Avalanche method (highest rate first) saves most interest mathematically. Snowball (smallest balance first) builds psychological momentum. 3k+8k+12k debts at 22%+15%+8%: avalanche saves ~800 vs snowball typically.
Strategy comparison.
Quick example
With debt 1 balance of 3,000 and debt 1 rate of 22% (plus debt 2 balance of 8,000 and debt 2 rate of 15%), the result is 896.00. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.
Which inputs matter most
You enter Debt 1 Balance, Debt 1 Rate, Debt 2 Balance, Debt 2 Rate, and Debt 3 Balance. Two inputs usually tip the answer one way or the other. Identify which ones matter most by flipping each value past a round threshold and watching whether the winning option changes.
What's happening under the hood
Approximation: avalanche typically saves 5-10% of total interest vs snowball. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.
Why payoff plans work
Debt feels overwhelming when it's an abstract total. Break it into a payoff date and a monthly figure and the problem becomes finite — you can see the finish line. That visibility is what this tool provides, and for many people it's the difference between dithering and acting.
What this doesn't capture
Real payoff journeys include missed payments, fee changes, balance transfers, and promotional rates that reset. The calculation assumes a steady plan; reality is rarely that clean. Use the figure as the best-case plan against which actual progress gets measured.
Where to go next
This calculation rarely sits alone in a planning exercise. If you're running these numbers, you'll probably also want the debt snowball vs avalanche planner, the debt payoff calculator, and the debt avalanche vs snowball comparison calculator — each one answers a different question in the same territory. Treating them as a set rather than in isolation usually produces a more honest picture.
Avalanche vs snowball produces savings based on the inputs provided.
