Frequently asked questions
Do extra loan payments reduce interest?
Usually, yes. Extra money applied to principal lowers the balance used to calculate future interest, as long as your lender applies it to principal.
Is it better to pay extra monthly or occasionally?
Both can help. Monthly payments are easy to automate, while a lump sum reduces principal immediately. Compare each option with your cash-flow needs.
Should I pay extra on a low-rate loan?
Consider your emergency savings, higher-rate debt, employer matches, taxes, and other goals before prioritizing extra loan payments.
