Debt Snowball Calculator

Add multiple debts, apply minimums plus an extra monthly amount, and estimate payoff order, total interest, and debt-free time.

Extra monthly amount

Strategy

—Months to debt-free

—Estimated interest

—Estimated total paid

—Debts entered

—Estimated payoff order

Monthly-interest model using the entered APR and fixed minimum payments. Real cards and loans can use daily interest, changing minimums, fees, promotional rates, or prepayment rules.

Connected debt and interest-rate workflow

v10.91 connects debt payoff, credit-card cost, loan comparison, APR/APY, effective-rate, weighted-rate, and hypothetical consolidation calculations while preserving every established historical canonical and calculation engine.

Compare assumptions, not offers

Results are deterministic browser-local math from the values you enter. They are useful for scenario comparison, but they are not a lender quote, approval decision, investment forecast, credit recommendation, or substitute for an account agreement.

How to use this Debt Snowball Calculator

Practical tips and limits

Change the assumptions to match the scenario you want to model. Results are browser-local estimates and are not lender, landlord, tax, legal, or investment advice. Real contracts can use different timing, fees, eligibility rules, and rate conventions.
