What is the difference between the debt snowball and debt avalanche methods?

The debt snowball method pays off the smallest balance first to build motivation, while the avalanche method targets the highest interest rate to save the most money. Both are automated in this free tool.

Can I include introductory APR (0% teaser rates) in the calculator?

Yes. Each debt allows you to enter an intro APR and the number of months it lasts. The calculator automatically switches to the regular APR after the intro period, giving you real‑world accuracy.

Is my debt information saved online?

No, everything runs locally in your browser. Data is saved only if you enable browser storage and never leaves your device. No account, no server, complete privacy.

Does this tool work for student loans and tax‑deductible interest?

Absolutely. You can mark any debt as tax‑deductible, and the calculator will adjust the effective interest rate based on your tax bracket, giving you a more accurate comparison.

Can I simulate one‑time lump sum payments or bonuses?

Yes, the tool includes a dedicated lump sum scheduler. Add any number of one‑time payments (e.g., tax refund, bonus) and specify the month they’ll occur.

What currencies are supported?

You can choose from USD, GBP, EUR, PKR, and INR. All amounts, charts, and PDFs will display in your selected currency symbol.

How does this compare to paid debt calculators like Undebt.it or Tally?

It offers most of the same advanced features – unlimited debts, intro APR, custom priority, inflation adjustment, and PDF export – completely free and without account creation. Paid tools often require subscriptions for full access.

Deciding between the debt snowball and debt avalanche methods can feel overwhelming.

What is the Debt Snowball vs. Debt Avalanche Method?

Both are structured repayment plans, but they prioritize your debts differently:

Debt Snowball: Pay off the smallest balance first while making minimum payments on everything else. Once the smallest debt is gone, roll its payment into the next smallest. This builds quick wins and psychological momentum—often recommended by Dave Ramsey.
Debt Avalanche: Attack the highest interest rate first, regardless of balance. Mathematically, this saves the most in interest charges and shortens your overall repayment timeline.

The best method depends on your personality and financial situation. Our calculator runs both strategies side‑by‑side so you can compare total interest, months until debt freedom, and monthly cash flow increases—empowering you to make an informed choice.
