Determine how much mortgage you can afford based on your salary in the USA. This calculator helps you understand the relationship between your income and potential mortgage payments by considering common mortgage rules and financial guidelines.
How the Mortgage Salary Calculator Works
The mortgage salary calculator estimates the maximum mortgage amount you can afford based on your gross annual salary. It uses standard mortgage affordability guidelines that consider your debt-to-income ratio and other financial factors.
Key Assumptions
The calculator uses these standard assumptions:
- Maximum debt-to-income ratio of 28-36%
- Standard mortgage interest rate of 6.5%
- 30-year fixed mortgage term
- No down payment (100% financing)
The calculator first calculates your monthly income, then determines the maximum monthly mortgage payment based on your income and the debt-to-income ratio. It then calculates the maximum mortgage amount using the standard mortgage payment formula.

Important Notes
This calculator provides an estimate based on standard assumptions. Actual mortgage approval depends on your complete financial situation, credit score, and lender requirements. Always consult with a mortgage professional for personalized advice.
The Formula Explained
The calculator uses these key formulas:
Monthly Income Calculation
Monthly Income = Annual Salary / 12
Maximum Monthly Mortgage Payment
Maximum Monthly Payment = Monthly Income × (Debt-to-Income Ratio / 100)
Maximum Mortgage Amount
Maximum Mortgage = [Maximum Monthly Payment × (1 - (1 + Interest Rate/12)^(-Term Months))] / (Interest Rate/12)
Where:
- Interest Rate = 6.5% (annual)
- Term Months = 360 (30 years)
Worked Examples
Example 1: $75,000 Annual Salary with 28% DTI
Monthly Income = $75,000 / 12 = $6,250
Maximum Monthly Payment = $6,250 × 0.28 = $1,750
Maximum Mortgage = [$1,750 × (1 - (1 + 0.065/12)^(-360))] / (0.065/12) ≈ $250,000
Example 2: $120,000 Annual Salary with 36% DTI
Monthly Income = $120,000 / 12 = $10,000
Maximum Monthly Payment = $10,000 × 0.36 = $3,600
Maximum Mortgage = [$3,600 × (1 - (1 + 0.065/12)^(-360))] / (0.065/12) ≈ $500,000
| Annual Salary | DTI Ratio | Max Monthly Payment | Max Mortgage Amount |
|---|---|---|---|
| $50,000 | 28% | $1,250 | $170,000 |
| $75,000 | 28% | $1,750 | $250,000 |
| $100,000 | 36% | $3,000 | $420,000 |
| $120,000 | 36% | $3,600 | $500,000 |
