How the Salary & Mortgage Calculator Works
The calculator uses standard mortgage formulas to compute monthly payments and total payments:M=P×(1+r)n−1r(1+r)n
Where:
- M = Monthly payment
- P = Mortgage principal (loan amount)
- r = Monthly interest rate (annual rate ÷ 12)
- n = Total number of payments (loan term × 12 months)
This formula accounts for compound interest, ensuring accurate estimates for fixed-rate mortgages.

Step 3: Enter Interest Rate

Step 4: Enter Loan Term

Example Calculation
Let’s say:
- Annual Salary: $80,000
- Mortgage Amount: $250,000
- Interest Rate: 4.5%
- Loan Term: 30 years
Calculation:
- Convert annual rate to monthly: 4.5% ÷ 12 = 0.375% (0.00375 as decimal)
- Total payments: 30 × 12 = 360 months
- Apply formula to get Monthly Payment: $1,266.71
- Total Payment over 30 years: $456,016
