A 15-year option versus 30 years
A 15-year mortgage can have a higher monthly payment but a lower rate and far less lifetime interest than a 30-year mortgage. Fees can narrow or widen that difference.

Reading the output
Payment and lifetime cost answer different questions
Two amortization schedules with fees
Each option uses the fixed-rate amortization payment formula. Lifetime borrowing cost equals all scheduled payments plus entered upfront fees minus the original principal.

Before relying on the result
Payments, APR and loan terms
Is the lowest mortgage payment always best?
No. A longer term can lower the payment while producing more lifetime interest.
Does this comparison use APR?
Enter note rates for payment calculations and fees separately. Review lender APR disclosures as an additional comparison.
