ⓘ About this tool 🔄 Last updated 1 Sep 2026 ✓ Reviewed by TopToolAI Team

Compare the snowball and avalanche methods for paying off multiple debts, and see how much faster you could be debt-free with a set monthly payment. Paying an extra PKR 5,000 a month toward a PKR 300,000 balance at 20% interest can cut the payoff time by more than a year compared to making only the minimum payment, and save a meaningful amount of interest along the way.

How to use Debt Payoff Calculator

Step-by-step guide to the boxes below. Open it only if you need help.

  1. 1
    Total debt Number

    The balance you owe right now.

    Example: 5000

  2. 2
    Interest rate % (annual) Number

    The yearly interest rate on this debt, for example 18.

    Example: 18

  3. 3
    Monthly payment Number

    What you can pay every month. It must be higher than the monthly interest, or the debt will never shrink.

    Example: 200

  4. 4

    Click the button under the boxes. If something is missing or not valid, a short message tells you which box to fix.

    You see how many months it takes to become debt-free and how much interest you will pay. Change any box and try again to compare different numbers.

Debt Payoff Calculator FAQs

What's the difference between snowball and avalanche?
Snowball pays off the smallest balance first for quick psychological wins; avalanche pays off the highest-interest debt first to save the most money overall.
Which method is mathematically better?
Avalanche typically saves more in total interest, but snowball can be easier to stick with if motivation is a bigger challenge than the math.
Can I switch methods partway through?
Yes — these are just strategies for the order you pay debts off in; you can switch whenever it suits you without any penalty.
Should I stop investing to pay off debt faster?
It depends on the interest rate — debt at a rate higher than your likely investment return is usually worth prioritizing first.
