Enter your total debt balance, the annual interest rate (APR), and how much you can pay each month. The calculator uses standard amortization to show you exactly how many months until you're debt-free, how much interest you'll pay, and a visual breakdown of your balance over time.
Avalanche vs Snowball: Which Is Better?
Both strategies work — the best one is the one you'll stick with.
- Avalanche method: Focus extra payments on the debt with the highest interest rate. This minimizes total interest paid and is mathematically optimal.
- Snowball method: Focus extra payments on the smallest balance. You'll get quick wins that keep you motivated, even if you pay slightly more in interest.
Research shows that the snowball method has higher completion rates because of its psychological benefits. But if you're disciplined, the avalanche method saves more money. Try our budgeting mistakes guide to avoid common traps.
Tips for Paying Off Debt Faster
- Pay more than the minimum — even $50 extra per month makes a massive difference.
- Automate payments — never miss a due date or late fee.
- Use windfalls wisely — tax refunds, bonuses, and side-hustle income should go straight to debt.

Frequently Asked Questions
What is the difference between the snowball and avalanche methods?
The avalanche method pays off debts with the highest interest rate first, saving you the most money in total interest. The snowball method pays off the smallest balance first, giving you quick psychological wins. Both work — avalanche is mathematically optimal, snowball keeps you motivated.
How much extra should I pay toward my debt each month?
Even an extra $50-100 per month can shave months or years off your payoff date and save hundreds in interest. Use this calculator to see the exact impact. The 50/30/20 rule suggests putting 20% of your income toward savings and debt repayment.
Should I save or pay off debt first?
Most financial advisors recommend building a small emergency fund ($1,000) first, then aggressively paying off high-interest debt (above 7-8%), then building full savings. If your debt interest rate is low (under 5%), you might benefit from investing simultaneously.
