Before building Debt Payoff Calculator, we checked calculator.net's debt payoff calculator directly — it's genuinely capable, supporting up to 20 separate debts with individual balances, rates, and minimum payments.
Avalanche vs snowball calculator, but only one method runs
It implements the avalanche method (highest interest rate paid off first) and explains, in text, that the snowball method (smallest balance first) "often results in borrowers paying more interest." True — but the calculator never actually runs the snowball numbers for you to see by how much, for your specific debts.
Debt avalanche interest saved, shown as an actual dollar figure
Feed the same two example debts — a $5,000 card at 22% and a $1,000 loan at 5% — into this tool with $200/month extra, and it simulates both strategies: avalanche finishes in 23 months for $1,088.14 in interest; snowball finishes in the same 23 months but costs $1,362.82 — $274.68 more, for prioritizing the smaller balance instead of the costlier one.
Debt snowball calculator multiple debts, side by side with avalanche
List any number of debts, one per line, and both strategies run simultaneously — payoff order, time, and total interest for each, so the tradeoff (avalanche usually cheaper, snowball sometimes easier to stick with) is a real comparison, not a claim you have to take on faith.
