Debt Payoff Calculator
See exactly when you’ll be debt-free — and how much you can save by increasing payments or lowering your interest rate. Enter your debts below and choose a payoff strategy to get your personalized plan.
How to Use This Calculator

- Choose a strategy — Select Debt Snowball (pay smallest balance first for motivation) or Debt Avalanche (pay highest interest first for maximum savings).
- Add extra payments — Enter any additional amount you can put toward debt each month.
- See your results — The calculator shows your payoff date, total interest paid, and how much you save compared to minimum-only payments.

Understanding Your Results
Payoff Date
This is the month and year your last debt will be fully paid off, based on the strategy and extra payment amount you selected. Adding even $50–$100/month extra can shave months or years off your timeline.
Total Interest Paid
The sum of all interest charges across all debts from today until full payoff. This number is often shocking — use it as motivation to pay more than the minimum.
Interest Savings
The difference between paying only minimums versus your chosen strategy with extra payments. This is money that stays in your pocket instead of going to lenders.

Debt Snowball vs. Debt Avalanche: Which Is Right for You?
| Debt Snowball | Debt Avalanche | |
|---|---|---|
| Order | Smallest balance first | Highest interest rate first |
| Best for | Motivation — quick wins keep you going | Savings — mathematically cheapest path |
| Interest cost | Slightly higher total interest | Lowest possible total interest |
| Psychology | ✅ Strong — eliminates debts fast | ❌ Slower first win if highest-rate debt is large |
| Recommendation | Choose this if you’ve struggled to stay motivated | Choose this if you’re disciplined and want to save the most |
Our advice: Run both strategies in the calculator and compare. The difference in total interest may surprise you — sometimes it’s only a few hundred dollars over years, making the snowball’s motivation worth the small extra cost.
Tips to Accelerate Your Debt Payoff
- Pay more than the minimum. On a $5,000 balance at 20% APR, paying $150/month instead of $100 saves over $2,000 in interest and finishes 3 years sooner.
- Lower your interest rate. A balance transfer card with 0% intro APR can save hundreds. Or ask your current issuer for a rate reduction.
- Use windfalls wisely. Tax refunds, bonuses, and side income should go straight to debt — not lifestyle upgrades.
- Automate extra payments. Schedule an automatic extra payment right after payday so you’re never tempted to skip it.
- Track your debt-to-income ratio. Use our DTI calculator monthly to watch your progress.
Real Example: $15,000 in Credit Card Debt
| Scenario | Monthly Payment | Payoff Time | Total Interest |
|---|---|---|---|
| Minimum only ($300) | $300 | ~6.5 years | ~$8,400 |
| Avalanche + $100 extra | $400 | ~4.5 years | ~$5,100 |
| Avalanche + $200 extra | $500 | ~3 years | ~$3,200 |
| 0% BT card + $400/mo | $400 | ~3.1 years | ~$450 (BT fee only) |
As you can see, the combination of a balance transfer and higher monthly payments saves over $7,900 in interest compared to minimum-only payments.
Frequently Asked Questions
Is this calculator accurate?
It provides close estimates based on standard amortization calculations. Actual interest may vary slightly due to compounding frequency, payment timing, and whether your issuer uses daily or monthly balance calculations.
Should I include my mortgage?
You can, but most people focus payoff strategies on high-interest consumer debt (credit cards, personal loans, medical bills). Mortgage rates are typically much lower, making early payoff less urgent.
What if I can’t afford even the minimum payments?
If minimums exceed your budget, consider: (1) calling each creditor to request a hardship program, (2) working with a nonprofit credit counseling agency (NFCC.org), or (3) exploring debt management plans. Avoid for-profit “debt settlement” companies.
How often should I recalculate?
Revisit your plan whenever your income changes, you pay off a debt, or you add new debt. Monthly check-ins keep you accountable.
Can I use this for student loans?
Yes. Enter each student loan as a separate debt with its balance, APR, and minimum payment. The calculator treats all debts equally regardless of type.
