Formula Used

Mortgage Payment Formula

The monthly payment (M) is calculated using the formula:

M = P [i(1 + i)ⁿ] / [(1 + i)ⁿ - 1]

Where:

P = Principal loan amount
i = Monthly interest rate (annual rate divided by 12)
n = Number of payments (amortization period in years × 12)

This formula uses the standard amortization method where equal payments are made each month, with part of each payment going toward interest and part going toward principal.

Worked Example

Let's calculate a mortgage for $300,000 at 5% annual interest over 25 years:

Principal (P) = $300,000
Annual interest rate = 5% → Monthly rate (i) = 5% ÷ 12 = 0.4167%
Amortization period = 25 years → Number of payments (n) = 25 × 12 = 300

Plugging these into the formula:

M = $300,000 [0.004167(1 + 0.004167)³⁰⁰] / [(1 + 0.004167)³⁰⁰ - 1]

Calculating this gives a monthly payment of approximately $1,834.84.

Over 25 years, you would pay a total of $698,542.36, with $398,542.36 going toward interest.

Frequently Asked Questions

What is the difference between fixed and variable rates?

Fixed rates remain the same throughout the loan term, providing predictable payments. Variable rates fluctuate with market interest rates, which can lead to lower payments initially but may increase over time.

How does the amortization period affect my payments?

A longer amortization period means lower monthly payments but more total interest paid. A shorter period results in higher monthly payments but less total interest.

What is the difference between principal and interest payments?

Principal payments reduce the amount you owe on the loan. Interest payments are the cost of borrowing the money. Early in the loan term, most payments go toward interest.
