Debt avalanche or debt snowball: which method fits?

Compare two popular payoff strategies and the tradeoff between mathematical savings and motivation.

This MayeleCalc guide explains the concept in plain language so you can use the related calculator with better context and confidence. Work through each section, review the practical example, and check the common mistakes before applying the result.

01

The avalanche targets the highest rate

The debt avalanche sends extra money to the highest-APR balance while minimum payments continue on every other debt. It generally minimizes interest when payments remain consistent.

02

The snowball targets the smallest balance

The debt snowball prioritizes the smallest balance. Early wins may strengthen motivation, even if a higher-rate account continues charging interest for longer.

03

Cash flow and behavior matter

A mathematically optimal strategy only works when it is sustainable. Choose an extra payment that leaves room for essentials and a basic emergency reserve.

04

Measure the payoff timeline

Track the estimated payoff month, total interest, and each balance. Recalculate after rate changes, new borrowing, or unexpected payments.

Practical example

See the idea in action

Compare at least three scenarios using the same starting amount. Change only one input at a time—such as the rate, term, or monthly contribution—so you can see exactly what drives the result.

Common mistakes to avoid

  • ×Comparing monthly payment without comparing total cost
  • ×Using an annual rate as though it were a monthly rate
  • ×Assuming an investment return is guaranteed

Key takeaways

  • Small rate changes can become meaningful over long periods
  • A lower payment does not always mean a lower total cost
  • Transparent assumptions make comparisons more useful

Put the idea into practice
