Paying off a loan early almost always saves you money, and the hit to your credit score is small and temporary. On a $20,000 loan at 9% over five years, paying just $150 extra a month gets you debt-free about 18 months sooner and saves roughly $1,580 in interest. The credit-score dip — a few points when the account closes — fades quickly and is rarely a reason to keep paying interest.
The fear that early payoff "hurts your credit" stops a lot of people from saving real money. So let's separate the two questions clearly: does it save money (almost always yes), and does it wreck your credit (almost always no).
1. The Short Answer
If your loan uses simple interest — as most auto and personal loans do — interest is charged each month on whatever you still owe. Pay the balance down faster, and there is less balance left for interest to grow on, so you pay less interest overall and finish sooner. That is a guaranteed return equal to your loan's rate.
The credit-score concern is real but minor. Closing an installment account can nudge your score down a few points temporarily, mostly because scoring models like to see active, open accounts. That small, short-term dip is almost never worth paying hundreds or thousands of dollars in extra interest to avoid.
2. How Much You Actually Save
Here is a $20,000 loan at 9% APR on a standard 5-year (60-month) term, paid on schedule versus paying $150 extra every month. This is the comparison the loan extra payment calculator runs on your real loan.
| Approach | Monthly Payment | Payoff Time | Total Interest |
|---|---|---|---|
| Scheduled payment | $415 | 60 months | $4,910 |
| Pay $150 extra/mo | $565 | 42 months | $3,330 |
That single change — $150 more a month — ends the loan 18 months early and saves $1,580 in interest. The earlier in the loan you start adding extra, the bigger the savings, because there is more balance for those early payments to knock out before interest piles on it.
Interest saved on a $20,000 loan at 9% by paying $150 extra each month — and you finish 18 months sooner. The credit-score dip is a few points, and temporary.
3. The Truth About the Credit-Score Hit
When you pay off an installment loan, the account is reported as closed and paid. Because scoring models give a little extra weight to open, active accounts, your score can slip a few points. That is the entire "early payoff hurts your credit" story — a small, temporary dip, not damage.
And there is an upside that often offsets it: your positive payment history on the loan stays on your credit report for years, and lowering your total debt can help in other ways, including your debt-to-income ratio. For most people, the few points are not worth keeping a balance — and interest charges — alive.
Two things to check before a big payoff: confirm there is no prepayment penalty in your loan agreement (uncommon, but worth a look), and confirm your loan uses simple interest rather than precomputed interest. With precomputed interest, some of the interest is fixed up front, so early payoff saves less.
4. See Your Own Savings: Use the Loan Extra Payment Calculator
Your loan's balance, rate, and remaining term decide the payoff. Enter them into the free loan extra payment calculator, then add an extra amount — $50, $100, $150 — and watch the payoff date and total interest drop.
The calculator makes the trade-off concrete: you will see exactly how many months and how many dollars each extra payment buys, so you can pick an amount that fits your budget. Run your real loan numbers here.

5. Which Debt to Pay Off First
Before you accelerate a loan, make sure it is the right debt to attack. The rule is simple: pay extra on your highest-rate debt first, because that is where each dollar saves the most.
Credit cards almost always come first
A credit card near 23.79% costs far more per dollar than a 9% auto or personal loan. If you are carrying a card balance, extra money belongs there before a lower-rate loan — see why a card balance barely moves for how punishing that rate is.
Keep a cushion before going all-in
Do not drain your emergency fund to kill a low-rate loan early. Keep enough set aside for surprises, then direct the extra to debt. A loan paid off a few months later is far better than a payoff that leaves you reaching for a high-rate card when something breaks.
Use the same engine on your other debts
The extra-payment math works on any balance. If you are juggling several, debt snowball vs avalanche shows which order saves the most, and the loan extra payment guide walks through the mechanics in depth.
6. The Called-Out Moment
You have wanted to throw extra money at your car loan for a while, but someone told you "paying it off early hurts your credit," so you hesitated — and kept paying interest you did not have to. That advice cost you real dollars to avoid a few imaginary points.
On a $20,000 loan at 9%, the hesitation has a price tag: about $1,580 in interest and 18 extra months of payments, traded away to protect a score that would have dipped slightly and recovered within months. The math is not close. Saving the interest wins almost every time.
FAQ: Paying Off a Loan Early
Does paying off a loan early hurt your credit score?
Usually only a little, and only temporarily. When you pay off an installment loan, the account is marked closed, and because scoring models weigh open accounts more heavily, your score may dip a few points. The drop is minor and short-lived, and the benefit of being out of debt and saving interest almost always outweighs it. Your payment history on the loan stays on your report and continues to help you.
How much money do you save by paying off a loan early?
It depends on your balance, rate, and how much extra you pay. On a $20,000 loan at 9% APR with a 5-year term, paying $150 extra each month pays it off about 18 months early and saves roughly $1,580 in interest. The higher your rate and the earlier you add extra payments, the more you save, because interest is charged on the remaining balance every month. The free loan extra payment calculator shows your exact figure.
Is it better to pay off a loan early or invest the money?
Compare your loan's interest rate to what you could reasonably earn investing. If your loan rate is higher than your expected investment return, paying off the loan is the guaranteed better return. For a 9% auto or personal loan, paying it down usually beats investing because few safe investments reliably return 9%. For very low-rate loans, investing may come out ahead.
Are there penalties for paying off a loan early?
Sometimes, but prepayment penalties are uncommon on most auto and personal loans. Before making large extra payments, check your loan agreement for a prepayment penalty and confirm whether your loan uses simple interest (where early payoff saves interest) or precomputed interest (where the interest is fixed up front). Most modern loans use simple interest, so paying early does save money.
Should I pay off my car loan or my credit card first?
Almost always the credit card first, because its rate is far higher. A credit card near 23.79% costs you much more per dollar than a 9% car loan, so every extra dollar saves more on the card. Pay the minimums on everything, then throw extra money at the highest-rate debt first — usually the credit card — before accelerating a lower-rate loan.
Does making extra payments on a loan lower my monthly payment?
Not usually — extra payments shorten the loan term rather than reduce the required monthly payment. Your scheduled payment stays the same, but the loan ends sooner because you are paying down principal faster. Some lenders offer a re-amortization that lowers the payment after a large lump sum, but by default extra payments just get you to a zero balance earlier.
