Formula

The formula for calculating mortgage payments is based on amortization:

Payment = (Loan Amount × r) ÷ (1 – (1 + r)^(-n))

Where:

• Loan Amount = principal borrowed
• r = interest rate per payment period
• n = total number of payments over the term

How to Use the Calculator

1. Enter your total loan amount.
2. Input your annual interest rate.
3. Enter the loan term in years.
4. Choose how many payments you make per year (12 = monthly, 24 = semi-monthly, 26 = biweekly, etc.).
5. Press Calculate to see your regular payment, total loan cost, and interest.

Example

Suppose you borrow $250,000 at a 5% annual interest rate for 30 years with monthly payments (12 per year).

• Loan Amount = $250,000
• Interest Rate = 5% annually
• Loan Term = 30 years
• Payments Per Year = 12
• n = 30 × 12 = 360 payments
• r = 5% ÷ 12 = 0.004167

Payment = (250,000 × 0.004167) ÷ (1 – (1.004167^-360)) ≈ $1,342.05

Over 30 years, you’d pay:

• Total Paid = $1,342.05 × 360 = $483,138
• Total Interest = $483,138 – $250,000 = $233,138
