Check your interest type first

The CFPB says that if you plan to pay your auto loan off early, you want to make sure lenders are using a simple interest rate.

Ask your lender which kind of interest your loan uses and how it applies a payment that arrives between due dates. For monthly extras and a one-time payment see the car loan early payoff calculator; for a mortgage, the biweekly mortgage payment calculator.

Frequently asked questions

Why does biweekly pay off a car loan faster?

There are 26 biweekly periods in a year, so 26 half payments add up to 13 full monthly payments instead of 12. That extra month of payment goes to the balance.

How much does biweekly save on a car loan?

On the example loan it ends the loan 5 months sooner and saves $486 of interest.

Is biweekly better than adding the same money each month?

On the example loan one extra payment a year spread over twelve months ends it in 4 years 7 months, against 4 years 7 months for biweekly. You can do it with no special plan from your lender.

Will my lender accept payments every 14 days?

Some do and some do not. A payment that sits until the monthly due date, or is not applied to the balance, saves almost nothing, so ask when each payment is applied and whether there is a fee.

Does this calculator match my lender's plan?

It assumes each half payment lands on the balance the day it is received, with interest charged at the rate divided by 26. A plan that holds the money until the monthly date will save less.
