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 ÷ 100)
n = Number of payments (loan term in years × 12)

This formula calculates the fixed monthly payment required to fully amortize a loan over the specified term.

Worked Example

Let's calculate a mortgage payment for a $200,000 loan at 4% annual interest over 30 years.

Principal (P) = $200,000
Annual interest rate = 4% → Monthly rate (r) = 4% ÷ 12 ÷ 100 = 0.003333
Loan term (n) = 30 years × 12 = 360 months

Plugging these values into the formula:

Calculation

Monthly Payment = $200,000 × (0.003333(1 + 0.003333)^360) / ((1 + 0.003333)^360 - 1)

Monthly Payment ≈ $200,000 × 0.006546 / 0.999999 ≈ $1,321.54

Your estimated monthly payment would be approximately $1,321.54.

Frequently Asked Questions

What is a mortgage payment?: A mortgage payment is the amount you pay each month to repay your home loan, which includes principal, interest, and sometimes taxes and insurance.
How does the interest rate affect my payment?: A higher interest rate means you'll pay more in interest over the life of the loan, increasing your total repayment amount and monthly payment.
Can I pay extra toward my mortgage?: Yes, paying extra toward your principal can reduce the total interest paid and shorten the loan term. The calculator can help you estimate the benefits of additional payments.
What is loan amortization?: Loan amortization is the process of paying off a loan in regular installments, with each payment applying first to the interest and then to the principal.
