Both simulations pay all minimums, then pour the extra (plus freed-up minimums from paid-off debts) into the target. Avalanche is always mathematically ≤ snowball on interest; snowball sometimes wins on psychology. Interest compounds monthly at APR÷12. If a debt's minimum doesn't cover its interest, the tool flags it. Logged payments reduce the live balance, so the strategies and chart always project from where you actually stand — deleting a payment record restores the balance. · jonestes.me
