- Credit cards – revolving balances
- Personal loans – installment debt
Simply enter your loan balance, interest rate, and monthly payments to see your debt-free date and test strategies. Credit Utilization

Loan Payoff Strategies You Can Test
Lump Sum Payments
- One-time extra payment reduces the principal immediately.
- Example: $2,000 lump sum on a $20,000 auto loan cuts ~6–8 months off repayment.
Extra Monthly Payments
- Add $100/month to principal → thousands saved.
Biweekly Payments
- 26 half-payments/year instead of 12 full payments → shortens mortgage or long-term loans.
Snowball vs Avalanche Method
| Method | How It Works | Best For | Drawbacks |
|---|---|---|---|
| Snowball | Pay the smallest balances first | Quick wins | May pay more interest |
| Avalanche | Pay highest interest first | Lowest cost overall | Progress feels slower |
Use the calculator to model both strategies and pick what keeps you consistent.
