- Annual Income = $90,000
- Monthly Debts = $500
- Down Payment = $40,000
- Interest Rate = 6%
- Loan Term = 30 Years
- Credit Score = Good

- Monthly Payment = $2,000
- DTI Ratio = 33%
This helps buyers understand their approximate purchasing power before applying for financing.
Understanding Debt-to-Income Ratio (DTI)
Debt-to-income ratio is one of the most important mortgage approval factors.
The formula is:
DTI=Monthly IncomeMonthly Debts+Mortgage Payment×100
Lower DTI ratios generally improve mortgage approval chances.
Recommended DTI Ratios
Most lenders prefer:
- Below 36% = Good
- Below 43% = Acceptable
- Above 50% = High risk
High debt levels may reduce borrowing capacity significantly.
Mortgage Payment Formula
The calculator estimates monthly mortgage payments using the standard amortization formula.
M=P×(1+r)n−1r(1+r)n
Where:
- M = Monthly payment
- P = Loan amount
- r = Monthly interest rate
- n = Total number of payments
This formula helps determine affordable mortgage payments over the loan term.
