How to Pay Off Debt Faster (Avalanche vs Snowball)
Short answer
Pay minimums on every balance, then put every extra dollar toward either the highest interest rate (avalanche) or the smallest balance (snowball). Avalanche usually saves more interest; snowball can be easier to stick with.
Speed comes from maths and behaviour. Pick a method, automate minimums, and attack one target balance with every spare pound or dollar.
Avalanche method
List debts by interest rate. Destroy the costliest rate first while paying minimums on the rest. Best for total interest saved.
Snowball method
List by balance size. Clear the smallest first for quick wins, then roll that payment into the next balance.
Example
Card at 22% with 1,200 left vs personal loan at 9% with 6,000 left. Avalanche hits the card first. Model timelines in the debt payoff planner.
Do not forget the EMI
If you refinance, compare the new EMI with the loan EMI calculator and loan comparison calculator before switching.

Change one input at a time so you build intuition. Write the formula, substitute values, then confirm with the free debt payoff planner. If the tool disagrees with your hand math, check units first (months vs years, percent vs decimal, inclusive ranges).
Common mistakes to avoid
- Mixing up percent and decimal forms (15% is 0.15, not 15).
- Using the wrong base when calculating a change or a reverse percentage.
- Ignoring fees, tax or daylight saving when the real-world total depends on them.
- Rounding too early in multi-step arithmetic.
How to practise
Invent three mini-problems from your own life β a bill, a grade, a trip, a loan quote β and solve them on paper before you open the calculator. Teaching the steps to someone else is one of the fastest ways to lock in the method.
