How to use it
- Enter the loan amount
- Enter the annual interest rate
- Enter the term in years
- Read the monthly payment, total interest and total of payments
The Mortgage Repayment Rates Calculator takes your loan amount, annual interest rate and term to instantly show three key figures: the monthly payment you’ll owe, the total interest you’ll pay over the life of the loan, and the overall amount you’ll have paid when the loan is finished. Knowing these numbers helps you compare loan offers, budget for housing costs, and avoid surprises at closing. The monthly payment is the amount you’ll remit each month; the total interest is the cost of borrowing; the total of payments is simply the sum of all monthly payments. You can also experiment with different rates or terms to see how small changes affect your long‑term cost, giving you leverage when negotiating with lenders.
Pro tips
- Round the loan amount to the nearest hundred to simplify calculations
- Enter the interest rate as a percent (e.g., 5 for 5%) not a decimal
- Include property taxes and insurance separately if you need a full housing cost picture
- Double‑check the term matches the amortization schedule you intend to use

Case study
Sarah was unsure if a 4.5% rate over 30 years fit her budget. She entered her $250,000 loan, the rate and term into the calculator and instantly saw a $1,264 monthly payment, $206,000 total interest and $456,000 total paid. Armed with those numbers, she negotiated a lower rate and saved thousands over the loan’s life.
