Quick answer: the minimum-payment trap

Paying only the minimum (5% of the balance) on a ₹1,00,000 balance at 42% APR takes 20 years 8 months and costs ₹2,26,999.56 in interest.

Overview of the Credit Card Calculator

The minimum amount due on a credit card is designed to be small, so the balance shrinks very slowly while interest keeps being added. Enter your balance, the APR, the minimum due percentage and any payment floor to see how long it would take to clear the card and what it costs — compared with paying a fixed amount each month.

Paying a fixed amount equal to your first minimum clears the card much sooner and saves a lot of interest. For a payoff plan see the Credit Card Payoff Calculator; for several debts use the Debt Payoff Calculator.

How We Calculate

The calculator applies the standard financial formulas step by step.

  1. Each month interest = balance × APR ÷ 12 is added to the balance.
  2. The minimum due is the larger of the percentage of the balance and the floor amount.
  3. Subtract the payment and repeat until the balance reaches zero, tracking interest and months.
  4. Compare with paying the first minimum every month as a fixed payment.
minimum due = max(floor, balance × %)   interest = balance × APR ÷ 12

Credit Card Calculator — Frequently Asked Questions

What is the minimum amount due?

The smallest payment you must make to avoid late fees — usually a percentage of the balance (often 5%) or a fixed floor.

Why does paying only the minimum take so long?

Interest is added every month, so most of the payment goes to interest at first and the balance falls slowly.

What is the cost of paying only the minimum?

Often more than the original balance in interest over many years. The calculator shows the exact figure.

How can I pay off my card faster?

Pay a fixed amount at least equal to your first minimum, or more; pay the full statement balance to avoid interest.

What is the interest-free period?

If you pay the full statement balance by the due date, new purchases usually carry no interest. Revolving a balance removes it.

Does the minimum due change each month?

Yes. As the balance falls, the percentage-based minimum falls too, until it hits the floor.

How is the credit card calculator calculated?

It uses the standard formula: minimum due = max(floor, balance × %)   interest = balance × APR ÷ 12 The full method and a worked example are shown on this page.

Is this financial advice?

No. The calculator gives estimates for planning and learning. Real offers vary by lender, product and date, so confirm the details with your bank, lender or a qualified adviser before deciding.

Can I use another currency?

Yes. The maths is identical in any currency; only the currency symbol shown in the results differs.

Is my data stored?

No. Everything is calculated in your browser and nothing you enter is uploaded or saved.
