Debt Snowball Calculator UK
Plan a debt snowball strategy by paying off the smallest balance first, then rolling each cleared payment into the next debt. This calculator estimates payoff order, debt-free date, interest saved and time saved.

How the snowball method works
The calculator targets the smallest balance first. Once that debt is cleared, its minimum payment rolls into the next smallest remaining debt, creating a larger snowball payment.

What this means
The debt snowball method is built around momentum. It may not always save the most interest compared with targeting the highest APR first, but it can make progress feel clearer and easier to stick with.
How the debt snowball method works
The debt snowball method focuses on clearing the smallest balance first while keeping minimum payments going on the other debts. Once the smallest debt is cleared, the money that was going to that debt is rolled into the next smallest balance.
The main benefit is momentum. Clearing one debt can make progress feel more visible, which may help some people stay consistent. The trade-off is that it does not always minimise total interest compared with targeting the highest APR first.
This calculator gives a general estimate only. Real interest, fees, promotional rates and lender rules can change the exact outcome.
Smallest balance first
The snowball method starts with the debt that has the lowest balance.
Roll payments forward
When one debt clears, its minimum payment is added to the next target debt.
Momentum focused
The goal is to make progress feel visible and easier to maintain.
How to use this result
Use the payoff order as a practical estimate. Focus on the smallest balance first while keeping minimum payments going on the others.
Once the first debt is cleared, avoid absorbing that freed-up money into everyday spending. Rolling it into the next debt is what creates the snowball effect.

Debt snowball calculator FAQs
What is the debt snowball method?
It is a payoff method where you clear the smallest debt first, then roll that payment into the next smallest debt.
Is snowball better than avalanche?
Snowball is often better for motivation. Avalanche usually saves more interest because it targets the highest APR first.
Should I still make minimum payments?
Yes. The snowball method assumes minimum payments continue on all debts while extra money targets one debt at a time.
Is this calculator financial advice?
No. This calculator gives a general estimate only and should not be treated as personal financial advice.
