How to use a credit card responsibly

Aim to pay the full statement balance by its due date. Purchase interest-free periods depend on your card’s terms and often require full repayment; paying only the minimum generally leaves a balance that attracts interest.
Know the statement date, payment due date, interest rate, minimum payment and fees. Set reminders or a suitable direct debit, and make sure the paying account has enough money. A payment instruction alone does not guarantee that payment succeeds.
Avoid treating cash advances as ordinary purchases. They may attract immediate interest and separate fees. Check annual, late-payment and foreign-currency charges; rewards rarely compensate for expensive interest on a carried balance.
Review each statement, keep your PIN and one-time passwords private, and report unfamiliar transactions promptly to your issuer. If you start carrying debt, reduce new spending and make a repayment plan rather than relying on the minimum indefinitely.

What happens if you pay only the minimum?

The minimum payment is the amount due each month, not the full balance you owe. It may keep the account up to date, but interest continues on the unpaid balance. This hypothetical example shows why repayment can take years even without new purchases.

Starting card balance: MUR 50,000.00
Annual interest rate: 24%
Assumed minimum-payment rule: 5% of the balance after monthly interest, or MUR 200.00, whichever is higher. The final payment is capped at the amount owed.

Pay only the shrinking minimum

8 years and 10 months (106 months)

Total interest charged: MUR 30,834.24
Total repaid, including interest: MUR 80,834.24

Keep paying MUR 2,550 each month

2 years and 2 months (26 months)

Total interest charged: MUR 14,110.11
Total repaid, including interest: MUR 64,110.11

Keeping the payment at MUR 2,550.00, rather than reducing it with the minimum, saves MUR 16,724.13 in interest in this example.

The first month, step by step

Monthly rate = 24% ÷ 12 = 2%.
Interest = MUR 50,000.00 × 2% = MUR 1,000.00.
Balance after interest = MUR 50,000.00 + MUR 1,000.00 = MUR 51,000.00.
Minimum payment = 5% × MUR 51,000.00 = MUR 2,550.00, which is above the MUR 200.00 floor.
Amount reducing your debt = MUR 2,550.00 − MUR 1,000.00 = MUR 1,550.00.
Balance carried into month 2 = MUR 50,000.00 − MUR 1,550.00 = MUR 48,450.00.

The same calculation repeats each month. In month 2, the minimum falls to MUR 2,470.95. As payments shrink, progress slows; the minimum eventually reaches the cash floor.

Illustration only, not a particular bank’s terms. Assumes no new purchases, fees, cash advances or missed payments; a constant rate; interest added before payment once a month and rounded to cents. Banks may calculate interest daily and use different minimum-payment rules. Check your statement and agreement. Each year is 12 repayment months, with a shorter final year. Paying the full statement balance on time may avoid purchase interest where your card’s grace-period conditions apply.

A simple monthly habit

For Rs 5,000 of planned card spending, set aside Rs 5,000 to pay the statement when due, plus any applicable fees. You do not need to carry an interest-bearing balance just to demonstrate responsible credit use. If full repayment becomes difficult, pay at least the required minimum on time where possible and contact the issuer before you miss a payment.
