How to use this tool
Enter your remaining balance and APR. Set a monthly payment you can afford—or a target payoff date in months—and calculate to see payoff time, total interest, and total amount paid.
Worked example
Example: a $12,000 remaining balance at 8% with $350/month payments pays off in about 38 months and costs roughly $1,300 in interest.
How it works
Enter your remaining loan balance and interest rate, then either a fixed monthly payment or a target payoff timeline in months. The calculator estimates months to pay off, total interest, and total amount paid. Fees and taxes are not included.
Limitations
Assumes extra payments apply as you specify and that the lender accepts them without penalty. Verify prepayment rules first.

Frequently asked questions
What calculation modes are available?
