Credit Card and Debt Payoff Calculator

Fixed monthly model: APR ÷ 12, interest added before payment, no fees, new purchases or rate changes. Percentage minimum uses the balance after interest and your editable floor; the default 25 is an assumption, not a provider term. Use one currency. Results are estimates, not financial advice or guarantees. Enter any named debts with fixed minimum payments, in one currency. Interest is added once at the start of each month. All minimums are paid first; extra and freed minimum payments are redistributed in the same month under a constant starting monthly budget. Snowball prioritizes remaining balance; avalanche prioritizes APR. Ties preserve input order. Both plans use the same strategy and inputs; the baseline only sets extra to zero. This separate model uses the opening balance, your minimum percentage and floor, and a fixed-payment comparison. Effective monthly rate = expm1(log1p(annual rate)/12); nominal monthly rate = annual rate/12. Both interpretations and your alternative floor are shown. Each payment is capped at balance plus interest. No fees, purchases, legal compliance assessment, or currency rounding. A remaining balance at 1,200 months means not repaid. The same fixed monthly payment is used for both plans, capped at balance plus that month’s interest. The fee is added to transferred principal once. The first N months have zero interest, then the user’s fallback rate applies, using the selected annual-rate interpretation. Blank fallback explicitly assumes the current rate. Interest is charged once on opening balance, payment is at month end. No new purchases, missed-payment terms, lender rules or daily interest are modeled. Values use your one monetary unit without currency rounding; a remaining balance at 1,200 months is not paid off. Cost differences are shown only when both plans repay.
