Mortgage Calculation Formula

The monthly mortgage payment is calculated using the following formula:

M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1 ] Where: M = Monthly payment P = Principal loan amount (Purchase price - Down payment) i = Monthly interest rate (Annual rate / 12) n = Number of payments (Amortization period × 12)

This formula uses the standard mortgage payment calculation method that accounts for the interest on both the original principal and the interest accumulated over time.

Worked Example

Let's calculate a mortgage payment for a $400,000 home with a 20% down payment, 25-year amortization, and 5% interest rate:

Down payment: $400,000 × 20% = $80,000
Principal: $400,000 - $80,000 = $320,000
Monthly rate: 5% ÷ 12 = 0.4167% or 0.004167
Number of payments: 25 × 12 = 300
Using the formula:
M = $320,000 [ 0.004167(1 + 0.004167)^300 ] / [ (1 + 0.004167)^300 - 1 ] M ≈ $2,124.50

Your estimated monthly payment would be $2,124.50, with a total interest paid of approximately $127,440 over the 25-year term.

Frequently Asked Questions

What is the difference between amortization and interest-only payments?

Amortization payments include both principal and interest, gradually reducing your loan balance. Interest-only payments only cover the interest portion, leaving the principal unchanged until the end of the term. Amortization is typically preferred as it builds equity over time.

How does the interest rate affect my monthly payment?

A higher interest rate increases your monthly payment because more of each payment goes toward interest. Conversely, a lower rate reduces your monthly payment and total interest paid over the life of the loan.

What is the difference between fixed and variable rate mortgages?

Fixed-rate mortgages have a constant interest rate for the entire term, providing predictable payments. Variable-rate mortgages adjust with market rates, which can lead to lower initial payments but may increase later. Fixed rates are generally more stable for budgeting.
