## How this is calculated

Runs a month-by-month amortization schedule with a one-time or recurring extra payment applied to the outstanding principal, compared against a no-prepayment baseline, to show interest saved and either time saved (reduce-tenure mode) or a lower EMI (reduce-EMI mode).

**Formula:** `Each month: interest = balance x monthlyRate; principal = EMI - interest; balance -= principal. On a prepayment month: balance -= prepaymentAmount (capped at balance). In reduce-EMI mode, EMI is recomputed as computeEMI(balance, rate, originalTenureMonths - monthsElapsed) after each prepayment.`

**Variables:**

- `EMI`: Fixed monthly installment; auto-computed from principal/rate/tenure unless the borrower supplies their actual EMI
- `monthlyRate`: Annual interest rate / 12 / 100
- `originalTenureMonths`: Remaining tenure in months before any prepayment

Reference: Matches the standard prepayment-impact methodology used by Groww and ET Money EMI prepayment calculators.

## Assumptions

- Reduce-tenure mode never recomputes EMI, so the loan finishes before the original tenure. Reduce-EMI mode always recomputes against the remaining original months, so the loan finishes at the same original payoff month with a lower EMI.
- Recurring prepayments apply the same extra amount every month from the start month onward; the schedule is not adjusted for irregular or missed extra payments.

## Frequently asked questions

### Does a small recurring prepayment really add up?

Yes, a modest extra amount paid every month compounds over the life of the loan since it reduces the principal, and therefore the interest charged, earlier and more often than a single lump sum of the same total size.
