Compares total cost (payment × number of payments). A lower monthly payment from a longer term can still cost more in total interest — that's the trade-off this highlights. Excludes fees and points. Not lending advice.

Cheaper payment vs. cheaper loan

A loan with a lower monthly payment isn't automatically cheaper — stretching the term lowers the payment but adds interest. Comparing total cost (every payment summed) reveals the real winner, which is often the shorter, higher-payment loan.

Quick FAQ

Should I always pick the lower total cost?

Usually, but cash flow matters too — a lower payment can be worth some extra interest if it keeps your budget safe. This shows both so you can weigh them.

What about fees?

This compares interest only. Origination fees and points can flip the result, so factor those in for a full apples-to-apples comparison.
