Formula Used

The calculator uses the standard mortgage payment formula:

Mortgage Payment Formula

Monthly Payment = P × [r(1 + r)^n] / [(1 + r)^n - 1]

Where:

P = Principal loan amount
r = Monthly interest rate (annual rate ÷ 12)
n = Number of payments (loan term in years × 12)

For this calculator, we also add monthly property taxes and insurance to the monthly payment.

The total monthly payment is calculated as:

Total Monthly Payment

Total Monthly Payment = Monthly Mortgage Payment + (Annual Property Taxes ÷ 12) + (Annual Insurance ÷ 12)

Worked Example

Let's calculate a 15-year mortgage payment for a $200,000 loan with a 4% interest rate, $3,000 annual property taxes, and $1,200 annual insurance.

Principal (P) = $200,000
Annual Interest Rate = 4% (0.04)
Loan Term = 15 years (180 months)
Monthly Interest Rate = 0.04 ÷ 12 = 0.003333
Monthly Mortgage Payment = $200,000 × [0.003333(1 + 0.003333)^180] / [(1 + 0.003333)^180 - 1] ≈ $1,224.64
Monthly Property Taxes = $3,000 ÷ 12 = $250
Monthly Insurance = $1,200 ÷ 12 = $100
Total Monthly Payment = $1,224.64 + $250 + $100 = $1,574.64

Your estimated monthly payment would be $1,574.64, with $22,222.80 paid in total interest over the 15-year period.
