Remaining Balance Over Time
How to Use This Loan Payoff Calculator
Enter your current loan balance, annual interest rate, and monthly payment. Then use the extra payment slider to see exactly how much time and interest you save by paying more each month.
How Interest Works on a Loan
Each month, interest is charged on your remaining balance. With a high interest rate (like credit card APRs of 20â30%), most of your minimum payment goes toward interest rather than reducing the principal. This is why it can take years to pay off even a modest balance with minimum payments.
- At 18% APR on a $10,000 balance: ~$150/month in interest alone
- A $250/month payment only reduces principal by ~$100
- Doubling to $500/month reduces principal by $350 â cutting payoff time dramatically
The Power of Extra Payments
Even $50â$100 extra per month can shave years off your loan and save thousands in interest. The earlier you make extra payments, the greater the impact because you're reducing the balance on which interest compounds.
Debt Payoff Strategies
Avalanche Method (Mathematically Optimal)
Pay minimums on all debts, then put every extra dollar toward the highest interest rate debt first. This minimizes total interest paid.
Snowball Method (Psychologically Motivating)
Pay minimums on all debts, then attack the smallest balance first. Quick wins build momentum and motivation to keep going.
When to Refinance Instead
If your loan has a very high interest rate (15%+), consider whether you can refinance to a lower rate before aggressively paying it down. A personal loan at 8% vs a credit card at 22% means every dollar goes much further.
Tips to Pay Off Debt Faster
- Set up automatic extra payments so you don't spend the money elsewhere
- Apply windfalls (tax refunds, bonuses) directly to the principal
- Pause contributions to non-employer-matched retirement accounts temporarily
- Sell unused items to generate a lump-sum payment
- Pick up a side gig and dedicate that income to debt payoff
