Snowball vs avalanche calculator in Excel (how-to)
A snowball vs avalanche calculator in Excel is a workbook that ranks debts, applies minimums, then pours extra payment into one target at a time. This page is the how-to — columns, inputs, and what the sheet should spit out — not another debate about which method is “morally better.” For the strategy overview, see snowball vs avalanche.
Inputs every calculator needs
- Debt name, balance, interest rate (APR), minimum payment
- One “extra payment” amount you can actually send each month
- Method toggle: snowball (lowest balance first) or avalanche (highest rate first)
- Optional: start month so payoff dates read as calendar months
Yellow = balances, rates, mins, extra.
Gray = order, interest, payoff month.
No macros.
How the sheet should calculate
- Sort (or RANK) debts by the active method.
- Each month: pay all minimums; add extra to the current target debt.
- When a balance hits zero, roll that payment into the next target (the “snowball” of cash flow).
- Show total interest and months-to-debt-free for the chosen method so you can flip and compare.
You do not need VBA. Helper columns with IF, MATCH/INDEX, or a simple ranked list plus a payment schedule table are enough for a personal tracker.
