How to Pay Off a Loan Faster
Extra principal payments attack the balance directly, so every future month charges you less interest.
At a glance
The Short Answer
The fastest way to kill a loan is extra payments applied to principal. On a $25,000 loan at 6% with a 5-year term, paying about $104 more per month ($587 instead of $483.32) pays it off a full year early and saves roughly $817 in interest.

Why Extra Principal Works So Well
Interest each month is computed on the remaining balance. An extra principal payment shrinks that balance immediately, so every subsequent month charges less interest and more of your regular payment goes to principal — a snowball effect. Early extra payments are worth the most because they reduce the balance for the longest time.
Four Proven Strategies
- Round up the payment: paying $500 instead of $483.32 costs little and quietly shortens the term.
- Make biweekly half-payments: 26 half-payments per year equals 13 full payments — one extra payment annually without feeling it.
- Apply windfalls: tax refunds and bonuses sent straight to principal cut months off the schedule.
- Refinance to a shorter term or lower rate: if rates have dropped or your credit has improved, reprice the remaining balance.
See It Before You Do It
Use the calculator above to preview the effect: rerun your loan with a shorter term to approximate an accelerated payoff. For the $25,000 example, switching from 5 years to 4 shows a payment of $587.13 and total interest of $3,182.03 — versus $3,999.20 on the original schedule.
Two Things to Check First
- Prepayment penalties: some lenders charge for early payoff; read your agreement before sending extra money.
- Payment application: tell the servicer extra amounts go to principal, not toward the next month's payment, or the benefit shrinks.
Frequently Asked Questions
Is it better to pay extra monthly or make one lump sum?
A lump sum today saves slightly more than the same total spread monthly, because the balance drops sooner. But consistent monthly extra payments are easier to budget — the difference is small, so pick what you will stick with.
Should I pay off my loan or invest the extra money?
Compare the loan rate to a realistic after-tax investment return. Paying off a 6% loan is a guaranteed 6% return; if your loan is at 3%, investing may win. High-interest debt almost always deserves priority.
Does paying off a loan early hurt my credit score?
Closing an installment account can cause a small, temporary dip because it changes your credit mix and history, but the effect is minor and short-lived compared with the interest you save.
How do biweekly payments pay a loan off faster?
Half a payment every two weeks adds up to 26 half-payments — 13 full payments a year instead of 12. That one extra payment per year can trim a 5-year loan by several months.
