Debt Snowball vs Avalanche: Which Strategy Saves More?
A factual mathematical comparison of interest savings and clearance timelines between the Debt Snowball and Debt Avalanche strategies.
When deciding between the Debt Snowball and Debt Avalanche methods, the choice comes down to prioritizing interest savings versus psychological momentum.
Fact: The Avalanche Method Saves More Money
Because the Debt Avalanche strategy targets accounts with the highest Annual Percentage Rates (APRs) first, it reduces total interest charges as fast as mathematically possible.
If you carry high-APR store cards (e.g. 29.9% APR) alongside lower-rate personal loans (e.g. 7.9% APR), targeting the store card first prevents daily compound interest from building up at nearly 30% annually.
Fact: The Snowball Method Clears First Accounts Faster
The Debt Snowball strategy targets accounts with the smallest principal balance first. If your smallest balance is £400, directing extra payments to that account will clear it in fewer months than tackling a £4,000 balance at a higher APR.
Clearing accounts early reduces the total number of bills you manage each month.
