Self-employed borrowers often face more hurdles in getting approved for a mortgage compared to traditional employees. Lenders want to see stable, verifiable income—but freelancers, contractors, and small business owners usually have fluctuating earnings and complex tax returns.

The Self-Employed Mortgage Calculator helps you estimate how much house you may qualify for by factoring in income, expenses, and debts. It uses lending rules like the 28/36 rule to approximate a safe and lender-friendly mortgage payment.

Formula

1. Net Income: Annual Income − Business Expenses
2. Net Monthly Income: Net Income ÷ 12
3. Max Housing Payment: Net Monthly Income × 28%
4. Max Total Debt Payment: Net Monthly Income × 36%
5. Available for Mortgage: Max Total Debt Payment − Other Debts
6. Qualifying Payment: Minimum of Max Housing Payment and Available for Mortgage
7. Loan Amount: Reverse-calculated from monthly payment using the mortgage amortization formula.

How to Use the Calculator

1. Enter your annual income.
2. Input your business expenses.
3. Add your other monthly debts (loans, credit cards, etc.).
4. Enter the loan term in years.
5. Input the expected interest rate.
6. Press calculate to see your qualifying payment and estimated loan amount.

Example

Suppose you earn $120,000 annually but spend $40,000 on business expenses.

• Net Income = $80,000 → Monthly ≈ $6,667
• Max Housing Payment (28%) ≈ $1,867
• Max Debt Payment (36%) ≈ $2,400
• With $400 in monthly debts, available for mortgage = $2,000
• Qualifying Payment = $1,867 (the smaller value)

With a 30-year mortgage at 6%, this supports a loan of about $312,000.
