Cosigner Loan Calculator

Estimate how adding a cosigner might improve your loan terms. Enter the loan amount and compare a higher rate (without cosigner) to a lower rate (with cosigner approval).

Calculate your payment

Enter values to calculate.

How it works

We don't change your credit; we show payment and total cost at two different rates so you can see the benefit of a stronger application with a cosigner.

When to use it

Use when considering asking a family member or other cosigner to help qualify or get a better rate.

Frequently asked questions

Is the cosigner responsible for the debt?

Yes. If you don't pay, the lender can require the cosigner to pay. Cosigning is a serious commitment.
