You can compare mortgage payments at different interest rates by keeping the home price, down payment, and loan term the same while changing only the interest rate. This makes it easier to see how the rate itself affects the estimated monthly principal-and-interest payment. Even a relatively small rate difference can affect the payment and the total interest paid over many years. You should also remember that the rate you see in an example may not be the rate you ultimately receive because actual offers depend on factors such as your credit, loan type, property, and lender. A mortgage rate calculator can help you test different rates and compare their effect on payments. You can also use the mortgage payment calculator to examine the payment under different loan scenarios and understand how changing the rate affects the overall cost.
