Refinancing a personal loan means taking a new loan to pay off the existing one. It makes sense in three situations and backfires in one very common way.
When it works
1. Your credit improved. A jump from 620 to 700 since you borrowed can cut your APR by 8-12 points.
2. Market rates fell meaningfully since origination.
3. You need a lower payment to stay current. Extending the term costs more overall but beats default.
When it does not
You have been paying for two years on a five-year loan and refinance into a new five-year term. The rate drops, the payment drops, and you now pay interest for seven years total instead of five. This is the most common refinancing mistake and it usually costs more than the original loan would have.
The break-even test
1. Remaining interest on the current loan. Ask your lender for the payoff quote and total remaining interest.
2. Total interest on the new loan over the term you would take.
3. Fees: new origination fee plus any prepayment penalty on the old loan.
4. Savings = (1) minus (2) minus (3).
If the result is not clearly positive, do not refinance. Model both with the loan payment calculator.
Keep the term honest
The cleanest rule: never refinance into a term longer than the time remaining on your current loan. If 34 months remain, take a 36-month refinance at most. That preserves the interest savings instead of trading them for a smaller payment.
Credit impact
Expect a temporary dip of a few points from the hard inquiry and the new account's zero age. The closed old account stays on your report for ten years and continues contributing positive history. Net effect after three to six months of on-time payments is usually neutral to positive.
Alternatives worth checking first
- Ask your current lender for a rate reduction. Some will re-price for improved credit without a new loan.
- Enroll in autopay for a 0.25%-0.50% discount if you have not.
- Just pay extra. With no prepayment penalty, adding $100 a month to a 15% loan often saves more than refinancing to 12% over a longer term.
