How This Calculator Works

This calculator organizes your accounts into a mathematical schedule. By allocating your minimum payments across all debts and concentrating any extra monthly funds on one target account, you accelerate principal reduction. Once the target account balance reaches zero, its payment is rolled into the next account.

Snowball vs. Avalanche Strategies Explained

The Debt Snowball method targets the debt with the smallest balance first, giving fast psychological momentum by clearing accounts early. The Debt Avalanche method targets the debt with the highest interest rate (APR) first, which mathematically minimizes the total interest you pay over the life of your debts.

Why Extra Payments Make a Powerful Difference

Adding even a modest extra monthly amount (£25, £50, or £100) speeds up repayment significantly. Extra payments directly reduce the principal balance, preventing future compound interest from accruing on that amount.
