Frequently asked questions
- Does paying extra on my car loan save money?
- Yes. Extra payments reduce principal immediately, so less interest accrues on the smaller balance. The earlier in the loan you add extra, the more you save because interest is front-loaded.
- Will my lender apply extra payments to principal?
- Usually, but not always automatically. Some lenders apply extra to the next scheduled payment instead. Tell your lender to apply additional amounts to principal, and confirm there's no prepayment penalty.
- Is it better to pay off the car or invest the money?
- If your loan rate is higher than what you'd reliably earn investing, paying off the car wins on a risk-adjusted basis. Lower-rate loans may favor investing — but the guaranteed return of avoiding interest is appealing.
