Mortgage Rate Comparison Calculator

Enter loan amount and term, then two rates. See monthly payment and total interest for each.

Compare two rates

Enter values to calculate.

How it works

We use the standard P&I formula for both rates. Compare monthly payment and total interest to see the cost of a higher rate.

When to use it

Use it to see how much a 0.25% rate change affects payment and total cost, or to compare lender offers.

Frequently asked questions

Same as loan comparison?

Similar. This one keeps amount and term fixed and varies only rate.

Include points?

No. Add points cost separately or use the mortgage points calculator.
