# Credit Card Interest: 50,000 Balance, Fixed 5,000 Monthly Payment

> The same 50,000 balance at 40% APR, but paying a fixed 5,000 a month instead of the minimum due, showing the interest and time saved.

## Scenario inputs

  "inputs": {
    "outstandingBalance": 50000,
    "annualInterestRate": 40,
    "minDuePercent": 5,
    "minimumDueFloor": 200,

## How this is calculated

Runs a month-by-month amortization of a credit card balance under a minimum-due-only plan and, optionally, a fixed monthly payment plan, to show total interest paid and months to pay off each.

**Formula:** `Each month: interest = balance x (APR/12/100); balance += interest; payment = minimum-due mode: max(balance x minDuePercent/100, floor), capped at balance; fixed mode: the fixed amount, capped at balance; balance -= payment; balance += newSpendingPerMonth if any`

**Variables:**

- `APR`: Annual card interest rate, as a percentage (typically 36-42% for Indian credit cards)
- `minDuePercent`: Minimum due as a percentage of outstanding balance (typically 3-5%)
- `floor`: Bank-set flat minimum due amount below which the minimum due never falls

Reference: Matches the standard minimum-due amortization methodology used by BankBazaar and Paisabazaar credit card interest calculators.

## Assumptions

- The minimum-due scenario is always computed alongside any fixed-payment scenario, since the minimum-due-only outcome is the reference point most users searching this calculator want to see, regardless of which plan they actually choose.
- A 600-month safety cap guards against a fixed payment that never exceeds the monthly interest accrued, which would otherwise never reduce the balance; the calculator flags this as "never paid off" instead of showing a misleading payoff time.

## Frequently asked questions

### How much faster does a fixed payment clear the balance than minimum due?

A fixed payment well above the minimum due typically clears the balance in a small fraction of the time minimum-due-only repayment would take, since the full payment amount reduces principal every month instead of shrinking alongside the balance.
