How Much House Can I Afford Calculator

How Much House Can You Afford Based on Your Salary?

Your salary determines the maximum mortgage payment a lender will approve, which directly translates to a home price range. Enter your income, debts, down payment, and the current mortgage rate in the calculator above. The result shows the maximum home you can purchase at current rates. Working backward from salary to home price prevents the common mistake of falling in love with a house, then discovering it exceeds your qualification - or worse, buying it and struggling with payments that consume too much of your income.

Salary-to-Home Price Quick Reference

At 6.5% rate, 10% down, minimal existing debt: $50,000 salary: max ~$175,000 home. $60,000: ~$215,000. $70,000: ~$255,000. $80,000: ~$295,000. $90,000: ~$335,000. $100,000: ~$370,000. $120,000: ~$450,000. $150,000: ~$565,000. $200,000: ~$755,000. These are approximate lender maximums. Comfortable spending (targeting 22-25% housing ratio instead of 28%) reduces each number by 15-20%. Dual-income households can combine salaries for qualification but should stress-test affordability on a single income as a precaution against income disruption.

Gross Salary vs Take-Home: The Real Budget

Lender qualification uses gross (pre-tax) income, but mortgage payments come from net (after-tax) pay. On $80,000 gross: take-home approximately $5,100/month (after federal tax, FICA, state tax). Lender-approved housing at 28%: $1,867. That $1,867 mortgage consumes 36.6% of take-home pay - significantly more burdensome than the 28% of gross suggests. The gap between gross-based qualification and net-based reality is why many homeowners who qualify for a mortgage amount still feel financially stretched. Using 25% of take-home pay as the housing ceiling produces a more comfortable ratio: $1,275 on $5,100 net, supporting approximately $220,000-$240,000 in mortgage.

How Do Raises and Career Growth Affect Affordability?

Your current salary determines today qualification, but career trajectory affects long-term sustainability. A 28-year-old earning $55,000 with expected 5% annual raises: income reaches $71,000 in 5 years, $92,000 in 10 years. A mortgage payment that feels tight at $55,000 becomes comfortable at $71,000 and easy at $92,000 - assuming the payment is fixed while income grows. Buying slightly above your comfort zone at the start of a high-growth career path may be rational if the payment consumes less than 30% of projected income within 3-5 years. This strategy does not work if career growth is uncertain or the starting stretch requires foregoing emergency savings.

Side Income and Qualification

Lenders count side income (freelance, rental, gig work) toward qualification only if documented on tax returns for at least 2 years and showing consistency or growth. A $75,000 salary plus $15,000 in documented freelance income: lenders may use $90,000 total for qualification. Undocumented cash income: not counted. Recent side hustle income (under 2 years): typically not counted. Rental income from an investment property: 75% of the rental amount (after a 25% vacancy factor) is added to qualifying income. The 2-year documentation requirement means starting a side business to boost home-buying income requires planning well before the mortgage application.

Student Loan Impact on Home Affordability

Student loans directly reduce mortgage qualification. A $400/month student loan payment on $70,000 income reduces the affordable home from $255,000 to approximately $200,000 ($55,000 less). On income-driven repayment with a $100/month payment: the impact is smaller, but lenders may use 0.5-1.0% of the total balance as the qualifying payment if the actual payment seems artificially low. A $50,000 student loan balance at 1% qualifying rate: $500/month imputed payment regardless of the actual IDR amount. This imputed calculation is lender-specific - some use the actual IDR payment, others use the higher imputed amount. Ask each lender about their student loan payment qualification methodology.

Reducing DTI Before Applying for a Mortgage

Pay off the smallest debt completely to eliminate a monthly payment line item. Even a $150/month credit card minimum removed from DTI adds $20,000-$25,000 in mortgage capacity. Pay down credit card balances below 30% utilization (reduces minimum payments and improves credit score simultaneously). Avoid large purchases or new credit accounts in the 6-12 months before applying. If possible, pay off a car loan - the typical $400-$600/month payment consumes $50,000-$80,000 in potential home-buying capacity. A strategic 6-month debt reduction plan before mortgage application can expand your affordable home price by $50,000-$100,000 while simultaneously improving your credit score for a better rate.

Joint vs Solo Application Considerations

Applying jointly with a spouse combines both incomes but also both debt obligations and the lower of the two credit scores. If one spouse has excellent credit (760) and the other has fair credit (640): the joint application may receive a worse rate than the high-score spouse alone. In this case, applying solo with the higher-credit spouse (if their income alone qualifies for enough) may produce a better rate and lower total cost despite the reduced qualifying income. After closing, refinancing to include both spouses once the lower score improves captures the additional income for future DTI calculations without the rate penalty of the lower score.
