Enter values to calculate.

How it works

We compute payment and total interest for each loan using the standard formula. Compare the totals to see which costs less over time, and whether a lower payment is worth more total interest.

When to use it

Use it to compare dealer vs bank rates, to compare 15- vs 30-year mortgages, or to see refinance savings.

Frequently asked questions
