## How this is calculated

Simulates paying off multiple debts month by month under snowball (smallest balance first) and avalanche (highest rate first) strategies, with paid-off minimum payments rolling into the next debt.

**Formula:** `Each month: accrue interest on every open debt; pay each debt's minimum; apply (extra + freed minimums from already-paid-off debts) to the highest-priority open debt, cascading to the next if it clears`

**Variables:**

- `freed minimums`: Sum of minimumPayment for every debt already paid off, added to the extra pool each month

Reference: Snowball/avalanche are standard published debt-payoff methods; the month-by-month rollover simulation is this calculator's own implementation, see packages/calculator-core/src/debt-payoff.ts.

## Assumptions

- Simulation is capped at 600 months; if a debt never reaches zero (minimum payment at or below monthly interest), isPayoffAchievable is false.
- Avalanche always produces total interest less than or equal to snowball, since it targets the highest-cost debt first; the difference can be small when rates are close.
- Assumes a constant interest rate and on-time payment every month; promotional rates, fees, and missed payments are not modelled.

## Frequently asked questions

### Does a small extra payment still make a meaningful difference?

Yes. Even a modest extra amount speeds up payoff and reduces total interest compared to paying only minimums, since it starts the rollover effect sooner once the first debt clears.
