You’re looking at Zillow listings again. Maybe it’s a three-bedroom with that updated kitchen, or a townhome closer to work. The price seems… doable? You’re earning decent money, got some savings, and everyone keeps saying rates are “stabilizing.” But then the panic hits: What if I buy too much house and end up drowning in payments?
I’ve sat across from hundreds of first-time buyers wrestling with this exact question. Some came in thinking they could afford a $400,000 home on a $65,000 salary (they couldn’t). Others were shocked to discover they actually qualified for way more than they thought. The gap between what you think you can afford and what the numbers actually say? That gap costs people either their dream home or their financial stability.
You need concrete answers, not vague advice about “living within your means.” How much house can you actually afford with your salary? More importantly, how do you use those mortgage calculators without getting a false sense of security?
I’m going to walk you through the real math, the formulas lenders actually use, and the costly mistakes I see people make when they skip the boring parts of affordability calculations.
Understanding the Real Math Behind Home Affordability
Most people approach this backward. They find a house they love, then try to make their salary fit the payment. That’s like picking out a car, then checking if you can reach the pedals.
Your salary isn’t the whole picture—it’s the starting point. What actually determines how much house you can afford is your gross monthly income multiplied against lending ratios, minus your existing debts, adjusted for down payment size and current interest rates. Sounds complicated because it is, but the formula itself is straightforward once you see it broken down.
When I started in mortgage lending back in 2009 (yes, right after everything imploded), one of my first clients was a nurse making about $72,000 a year. She had her heart set on a $315,000 condo. Her reasoning? “I can afford $2,000 a month, and that’s what the payment would be.” Except she had a $450 car payment and $12,000 in credit card debt she conveniently forgot to mention. Her actual qualification? Closer to $240,000. She was furious with me, like I personally set the lending standards.
But those standards exist for a reason—they’re designed to prevent you from becoming “house poor,” where you technically own a home but can’t afford to live in it comfortably.
Here’s what lenders actually calculate:
Your front-end ratio (housing expense ratio): Your total monthly housing payment shouldn’t exceed 28% of your gross monthly income. This includes principal, interest, property taxes, homeowners insurance, and any HOA fees. Everything rolled into one payment.
Your back-end ratio (total debt ratio): All your monthly debt payments combined—mortgage, car loans, student loans, credit cards, everything—shouldn’t exceed 36% of your gross monthly income.
These aren’t arbitrary. The Consumer Financial Protection Bureau has extensively documented that borrowers who exceed these ratios face significantly higher default rates. Banks aren’t being mean; they’re being mathematically cautious.
Some quick mental math you can do right now: Take your annual salary, divide by 12 to get your monthly gross income, then multiply by 0.28. That’s roughly your maximum monthly housing payment. Making $80,000? That’s $6,667 monthly gross, times 0.28 equals $1,867 maximum housing payment.
But wait—that’s just the start.
The 28/36 Rule and Why Lenders Use It
The 28/36 rule sounds like some secret code, but it’s been the backbone of mortgage qualifying since the 1980s. Even after the 2008 crisis, even with all the fancy new loan products, this ratio persists because it works.
28% front-end, 36% back-end. Two numbers that can make or break your home buying dreams.
Why these specific percentages? They’re based on decades of default data showing that when people spend more than 28% of their income on housing, their ability to absorb unexpected expenses (broken water heater, medical bills, job loss) drops significantly. When total debt exceeds 36%, the risk of default climbs sharply.
In my experience, the people who get frustrated with these limits are usually the ones who don’t carry other debt. “I don’t have car payments or student loans, why can’t I spend 35% on housing?” And technically, you sometimes can—some lenders will approve slightly higher ratios if your credit score is excellent and you have substantial savings. Fannie Mae’s guidelines allow for flexibility with compensating factors.
But here’s where I get opinionated: Just because you can get approved for a higher ratio doesn’t mean you should max it out. I’ve seen too many people who squeaked through at 33% front-end ratio, then spent the next five years stressed about every minor expense, never taking a vacation, eating ramen to make the mortgage. That’s not homeownership; that’s a prison sentence.
Let’s run real numbers. Say you earn $90,000 annually:
- Monthly gross income: $7,500
- Maximum front-end (28%): $2,100 for housing
- Maximum back-end (36%): $2,700 for all debt
If you have $400 in other monthly debt (car, student loans, credit cards), that leaves you 2,300forhousing(2,300forhousing(2,700 – $400). But your front-end limit is $2,100, so that’s your ceiling.
Now work backward. With a $2,100 monthly payment at a 7% interest rate on a 30-year mortgage, after accounting for property taxes (say 1.2% annually) and insurance (roughly $100/month), you’re looking at about a $280,000 to $300,000 home price, depending on your down payment.
That might feel low if you’re shopping in a high-cost market. But that’s the reality of affordability based on salary. Your feelings about housing prices don’t change the math.
How to Actually Use a Mortgage Calculator (and What Numbers to Plug In)
Most people use mortgage calculators wrong. They plug in the home price they want, look at the monthly payment, and think “Yeah, I can swing that.” Wrong approach entirely.
You need to start with your income, calculate your maximum payment using the 28/36 rule, then let the calculator tell you what price range that payment supports. Work backward from what you can afford to what you should shop for.
Freddie Mac’s mortgage calculator is one of the more realistic ones because it forces you to include property taxes and insurance, not just principal and interest. A lot of the bank calculators show you artificially low payments by hiding the full PITI (Principal, Interest, Taxes, Insurance).
Here’s what you actually need to input accurately:
Your gross monthly income: Not your take-home. Your salary before taxes and deductions. If you’re paid bi-weekly, multiply one paycheck by 26 and divide by 12. If you get bonuses or commission, lenders typically average the last two years.
Current debts: Everything with a monthly payment that appears on your credit report. Car loans, student loans, personal loans, credit card minimum payments (they use the minimum showing on your statement, not what you typically pay). Child support counts. Your Netflix subscription doesn’t.
Down payment amount: This changes everything. Put down 20% and you avoid PMI (private mortgage insurance), which can add 100−100−300 to your monthly payment. But even 3-5% down is acceptable on many conventional loans and FHA loans.
Interest rate: Don’t use the calculator’s default rate. Check what rates you actually qualify for based on your credit score. As of 2025, someone with a 760 credit score might get 6.5%, while a 680 score might be looking at 7.2%. That difference adds up—on a $300,000 loan, it’s about $140 more per month.
Property taxes and insurance: This is where people get killed. In Texas, property taxes can hit 2-3% of home value annually. In California, it’s closer to 0.8% thanks to Prop 13. Don’t know the tax rate in your target area? Look up comparable homes on Zillow—they usually show annual tax amounts. For insurance, call a local agent and get a quote. Ballparking it as “$100/month” when it’s actually $250 will destroy your budget.
HOA fees: If you’re buying a condo or in a planned community, these aren’t optional. They count toward your front-end ratio because they’re part of your housing expense.
I had a client in 2022 who used an online calculator, saw she could afford the payment on a $380,000 home, and made an offer. When we ran her actual application, her property tax estimate was off by $180/month (she used the current assessed value, not the purchase price, which resets the tax basis in many states), and she hadn’t accounted for the $220 HOA fee. She didn’t qualify. Lost her earnest money deposit because she couldn’t close. Using the calculator correctly would’ve saved her $2,500 and weeks of stress.
Take the five extra minutes to input real numbers, not aspirational ones.
Beyond the Calculator: Hidden Costs That Kill Your Budget
Calculators show you if you qualify. They don’t show you if you can actually live on what’s left over.
I’m going to be blunt about this: The bank’s version of “affordable” and your version of “I can sleep at night” aren’t always the same. Lenders approve you based on ratios. They don’t care if you want to eat out occasionally, save for retirement, or ever replace your car.
The hidden costs everyone forgets:
Maintenance and repairs: The standard estimate is 1% of home value annually, but older homes can easily hit 2-3%. That $300,000 house? Budget 3,000−3,000−5,000 per year for stuff breaking. And it will break. Water heaters die, roofs leak, HVAC systems fail—usually right after you close.
Utilities: Rent a 900 sq ft apartment? Your electric bill might be $80. Buy a 2,200 sq ft house? Try 180−180−250, especially in hot/cold climates. Water, gas, trash, internet—it adds up to an extra 200−200−400 monthly compared to renting.
Closing costs: Usually 2-5% of purchase price. On a $300,000 home, that’s 6,000−6,000−15,000 due at closing beyond your down payment. Some of this can be negotiated with the seller or rolled into the loan, but you need cash ready.
PMI: If you put down less than 20%, private mortgage insurance typically costs 0.5-1% of the loan amount annually. On a $285,000 loan (5% down on $300k), that’s $1,425 per year, or about $119/month added to your payment. It’s not permanent—you can remove it once you hit 20% equity—but it affects affordability in the early years.
Furniture and immediate repairs: You’re not moving into a fully furnished, perfect house. Budget 5,000−5,000−10,000 for essentials: lawn mower, tools, window treatments, furniture for rooms you didn’t have before, the repairs the inspector noted that you agreed to fix yourself.
Opportunity cost: This is the big one nobody talks about. Every dollar in your mortgage is a dollar not invested elsewhere. If you max out your housing budget, you’re probably sacrificing retirement contributions, emergency fund building, or investment opportunities. There’s a real cost to being house-rich and cash-poor.
Back in 2019, I watched a couple buy at the absolute top of their approval—$425,000 on their combined $135,000 income. They qualified, barely, at 35% back-end ratio. Two years later, their air conditioning died in July (Florida). $8,000 to replace it. They didn’t have it. They had to take out a personal loan at 11% interest to fix it because they’d emptied their savings for the down payment and had nothing left. They’re still angry about it, and honestly, I don’t blame them—but they also ignored the advice to buy under their maximum approval.
When calculators say you can afford $X, think of that as your ceiling, not your target. Aim for 20% below your maximum. That buffer is your sanity, your emergency fund, your ability to actually enjoy the house instead of just surviving in it.
What Your Salary Really Qualifies You For (Real Examples)
Theory is great. Real numbers are better. What does your actual salary qualify you for in practical terms?
I’m using current typical numbers: 7% interest rate, 30-year fixed mortgage, 1.2% property tax rate, $150/month insurance, no HOA, and following the 28% front-end ratio. Your market will vary, but these examples show the methodology.
$50,000 annual salary:
- Monthly gross: $4,167
- Max housing payment (28%): $1,167
- Estimated home price range: 160,000−160,000−175,000
- With 5% down: Loan amount around 152,000−152,000−166,000
Reality check: In many markets, this doesn’t buy much. But it’s what the numbers support. Your options are increase your down payment (reduces loan amount and monthly payment), improve your credit score (lower rate), reduce other debts (frees up back-end ratio), or increase income.
$75,000 annual salary:
- Monthly gross: $6,250
- Max housing payment (28%): $1,750
- Estimated home price range: 245,000−245,000−265,000
- With 10% down: Loan amount around 220,000−220,000−240,000
More realistic range for many markets. If you have no other debt, you might squeeze up to 285,000−285,000−300,000 depending on your down payment size.
$100,000 annual salary:
- Monthly gross: $8,333
- Max housing payment (28%): $2,333
- Estimated home price range: 330,000−330,000−360,000
- With 20% down: Loan amount around 265,000−265,000−290,000
Six figures sounds like a lot until you’re shopping in Seattle or Austin or Boston, where median home prices exceed $500,000. The math doesn’t care about your market—it only cares about your income and the ratios.
$150,000 annual salary (household):
- Monthly gross: $12,500
- Max housing payment (28%): $3,500
- Estimated home price range: 500,000−500,000−550,000
- With 20% down: Loan amount around 400,000−400,000−440,000
This is where most dual-income professional households land. Comfortable in mid-tier markets, still stretching in high-cost coastal cities.
$60,000 annual salary with 15,000inotherannualdebt(15,000inotherannualdebt(1,250/month):
- Monthly gross: $5,000
- Max back-end ratio (36%): $1,800 total debt
- Minus existing debt: $1,800 – $1,250 = $550 for housing
- This is below the 28% front-end limit ($1,400), so back-end controls
- Estimated home price range: 75,000−75,000−85,000
See the problem? This person’s other debt destroyed their home buying power. They make $60k but can only afford a home someone making $25k could afford. Debt is the killer. Pay it down before you shop for houses.
These estimates assume you’re using conventional financing. FHA loans use slightly different ratios (31%/43% instead of 28%/36%) and allow lower credit scores and smaller down payments, which can help first-time buyers, but you’ll pay mortgage insurance for the life of the loan unless you refinance later.
The mortgage pre-qualification income requirements aren’t designed to punish you. They’re designed to prevent you from defaulting. If you’re feeling limited by what your salary qualifies you for, you have three levers: increase income, reduce debt, or save a larger down payment. There’s no secret fourth option where the math suddenly changes because you really want that particular house.
What Actually Matters More Than the Calculator Says
I’m going to contradict myself slightly. The calculators and ratios are critical—ignore them at your peril—but they don’t capture everything.
Your personal risk tolerance matters. Some people sleep fine at 35% housing ratio. Others panic at 25%. If you’re someone who needs a fat emergency fund and low fixed costs to feel secure, buy below your maximum even if the bank approves you for more. If you’re comfortable with risk and have stable high income, maybe you stretch a bit.
Your life stage matters. Buying in your 20s when you might relocate for career opportunities? Maybe don’t max out. Buying in your 40s with stable careers and kids in local schools? Different calculation.
Your market trajectory matters. Buying in a rapidly appreciating market where waiting a year prices you out? Sometimes stretching makes sense because the alternative is being permanently priced out. Buying in a flat or declining market? You can afford to wait and save more.
The specific house matters. A $280,000 new construction with warranties and efficient systems is different from a $280,000 1960s charmer that needs a new roof and updated electrical. One will drain your maintenance budget; the other won’t.
But—and this is crucial—none of those factors should push you to ignore the fundamental math. They might justify aiming for the higher end of your range instead of the lower end, but they don’t justify buying a $400,000 house on $75,000 income just because “it’s your dream home” or “the market is hot.”
I worked with a teacher making $58,000 who wanted to buy in a gentrifying neighborhood where prices were climbing 8% annually. His qualification was around $225,000. Homes in his target area were hitting $260,000. I told him honestly: “You can’t afford this neighborhood right now.” He was devastated. But you know what happened? He spent 18 months aggressively saving, picked up summer work, paid off his car, and improved his credit score by 40 points. His qualification jumped to $265,000. He bought a house for $272,000 (with seller covering some closing costs). It’s now worth about $315,000. He made it work, but he did it by changing his financial position, not by pretending the math didn’t exist.
How to Improve Your Buying Power
If the numbers disappointed you, you’re not stuck. Here’s what actually moves the needle on how much house you can afford:
Increase your income. Obvious but worth stating. A $10,000 raise increases your home buying power by roughly 35,000−35,000−40,000. Side hustles, overtime, promotions—they all count if you can document two years of consistent extra income.
Obliterate your other debt. Every $100/month in debt you eliminate frees up roughly 15,000−15,000−18,000 in home buying power. Pay off that car, knock out the credit cards, refinance student loans to lower payments.
Improve your credit score. A jump from 680 to 740 might reduce your rate by 0.5%, which on a $300,000 loan saves you about $90/month and potentially lets you qualify for about $12,000 more home.
Save a bigger down payment. 20% down eliminates PMI, lowering your monthly payment and increasing what you qualify for. Plus, sellers take you more seriously with substantial down payment.
Consider different loan products. FHA, VA (if you’re a veteran), USDA (for rural properties), first-time homebuyer programs—they all have different ratio limits and requirements that might work better for your situation.
Shop in different areas. Sometimes the same commute distance in a different direction cuts home prices by 30%. Property taxes vary wildly between municipalities. You might not be able to afford your dream neighborhood yet, but maybe you can afford the next one over.
What doesn’t work: Lying on your application, using gift money you have to repay under the table, assuming “we’ll just make it work somehow,” or believing rates will definitely drop next year so you’ll refinance. Qualify for the loan you’re actually getting at the rate you’re actually paying, not some future hypothetical scenario.
Ultimately, figuring out how much house you can afford with your salary isn’t about gaming a calculator or finding a lenient lender. It’s about honest math and honest self-assessment. Can you actually afford $2,200/month in housing and still live the life you want? Can you handle a major repair without financial catastrophe? Will you resent the house in three years because you can’t afford to do anything else?
The calculator gives you the ceiling. Your judgment determines where you actually buy within that range. And if you’re smart, you leave yourself breathing room, because houses are supposed to improve your life, not dominate it.
Frequently Asked Questions
How much house can I afford making $60,000 a year?
With a $60,000 salary, your gross monthly income is $5,000. Following the 28% housing ratio, your maximum monthly payment would be $1,400. Assuming a 7% interest rate, property taxes around 1.2%, and homeowners insurance, you could afford a home priced between 195,000−195,000−215,000 depending on your down payment size and whether you have other debts. If you have significant car payments or student loans, your qualification could drop considerably based on the 36% back-end ratio.
What is the 28/36 rule in mortgage lending?
The 28/36 rule is the standard debt-to-income ratio most lenders use for mortgage qualification. The 28% front-end ratio means your total housing payment (principal, interest, taxes, insurance, HOA) shouldn’t exceed 28% of your gross monthly income. The 36% back-end ratio means all your monthly debt payments combined—including the mortgage—shouldn’t exceed 36% of gross income. These ratios help ensure you can afford your mortgage payment while managing other financial obligations.
Do mortgage calculators include property taxes and insurance?
Many basic mortgage calculators only show principal and interest, which significantly underestimates your actual monthly payment. Better calculators include PITI (Principal, Interest, Taxes, Insurance), plus HOA fees if applicable. Always verify what’s included. Property taxes alone can add 200−200−500+ monthly depending on location and home value, while insurance typically adds 100−100−250. Using a calculator that excludes these costs will give you a false affordability picture.
How much do I need to make to afford a $300,000 house?
To comfortably afford a $300,000 house following the 28% rule, you’d need an annual salary of roughly 75,000−75,000−85,000, depending on your down payment, current interest rates, property taxes in your area, and other debts. With 10% down ($30,000), a 7% interest rate, and typical property taxes and insurance, your monthly payment would be around 2,100−2,100−2,300. To keep that at 28% of income, you’d need monthly gross income of 7,500−7,500−8,200, which equals 90,000−90,000−98,000 annually.
Should I get pre-qualified or pre-approved before house hunting?
Get pre-approved, not just pre-qualified. Pre-qualification is an estimate based on information you provide without verification. Pre-approval means the lender actually checked your credit, verified your income and assets, and committed to lending you a specific amount (subject to appraisal and final underwriting). Sellers and their agents take pre-approved buyers seriously; pre-qualified buyers less so. In competitive markets, you won’t even get a showing in some cases without a pre-approval letter. It takes a few extra hours but can mean the difference between getting your offer accepted or losing the house.
