Minimum Amount Due Trap: Why Paying It Costs You Lakhs

Paying only the minimum amount due on a credit card keeps you clear of late fees and keeps your account current, but it does almost nothing to reduce what you owe. Interest of around 3% to 3.75% a month, plus 18% GST on that interest, eats most of each minimum payment. On a ₹1,00,000 balance, paying only the minimum can take around 30 years and cost more than ₹4 lakh in interest and GST.

RBI considers this risk serious enough that card statements must carry a warning that making only the minimum payment every month stretches repayment over months or years with compounded interest on the outstanding balance.

What the minimum amount due is

The minimum amount due (MAD) is the smallest payment that keeps your account in good standing for that month. It is not a discount on the bill, and it is not an instalment plan.

Formulas vary by issuer. Common versions are:

RBI's credit card directions require that the minimum amount due be set so that it does not cause negative amortisation, in other words, paying the minimum must not let the balance grow. RBI has penalised at least one bank for failing to ensure this. But "not growing" is a low bar. As the example below shows, the balance can shrink so slowly that it barely matters.

What paying only the minimum actually triggers

Paying the MAD on time protects you from two things: late payment charges, and being reported as past due to bureaus such as TransUnion CIBIL. It does not protect you from interest. The moment you pay less than the total amount due:

1. The interest-free period is lost. Interest is charged on the full statement balance from each transaction date, including on the part you paid, until the payment is credited.
2. New purchases attract interest from day one. Every swipe while a balance is carried accrues interest daily until the whole balance is cleared.
3. GST is added. 18% GST is levied on the finance charges, turning a 3.6% monthly rate into about 4.25%.
4. Utilization stays high. The reported balance barely moves, which can keep your credit score suppressed. See our guide to the credit utilization ratio.

The full mechanics are in how credit card interest works.

Worked example: ₹1 lakh, minimum payments only

Assumptions:

• Outstanding balance: ₹1,00,000
• Interest rate: 3.6% a month (43.2% a year), a typical rate for Indian cards
• GST: 18% on interest
• Minimum amount due: 5% of the balance, rounded up to the nearest ₹10, minimum ₹200
• No new spending and no late payments
• Interest is modelled monthly on the statement balance for simplicity; actual daily-balance calculations differ slightly

Month 1:

• Interest: ₹1,00,000 x 3.6% = ₹3,600
• GST on interest: ₹3,600 x 18% = ₹648
• New balance: ₹1,00,000 + ₹3,600 + ₹648 = ₹1,04,248
• Minimum due (5%): ₹5,220
• Balance after payment: ₹99,028

You paid ₹5,220, but your balance fell by only ₹972. More than 80% of the payment, ₹4,248, went to interest and GST.

Month 2: interest of ₹3,565.01 plus GST of ₹641.70 takes the balance to ₹1,03,234.71. The minimum due is now ₹5,170, leaving ₹98,064.71.

As the balance shrinks, so does the minimum payment, which is exactly why the debt lingers. Here is how it plays out:

After a full year of on-time minimum payments totalling ₹59,390, you still owe ₹88,948. After five years you have paid well over twice the original balance and still owe more than half of it. The whole ₹1,00,000 costs ₹5.2 lakh to clear, more than five times the amount you borrowed.

How fixed payments change the picture

The same ₹1,00,000 balance, same rate and GST, but paying a fixed amount each month instead of the shrinking minimum:

Paying a flat ₹5,000, roughly what the first minimum due was, cuts the payoff time from about 30 years to under 4 years and saves nearly ₹3 lakh. The trap is not the size of the first minimum payment; it is letting the payment shrink along with the balance.

How to get out of the minimum due trap

1. Stop adding to the balance

While you carry a balance, every new purchase attracts interest from the day you make it. Switch day-to-day spending to a debit card or UPI until the card is cleared.

2. Fix your payment amount

Decide on a fixed monthly amount you can sustain, at least your first month's minimum due and preferably more, and keep paying it even as the minimum falls. Set up a standing instruction for that amount.

3. Convert to a cheaper loan

If the balance will take more than a few months to clear, moving it to a lower-rate product usually saves money:

• Card EMI conversion: many issuers let you convert the outstanding balance or large purchases into EMIs at a lower rate than revolving interest. Check the processing fee and remember GST applies to the interest and fee.
• Personal loan: personal loan rates for good-credit borrowers are generally well below card revolving rates. Use the loan to clear the card in one go, then close the cycle of revolving. Our personal loan interest rates guide explains what affects the rate you are offered.
• Loan against FD or gold: if you have the collateral, these are typically cheaper still.

Whatever you choose, compare total cost, including fees and GST, not just the headline rate.

4. Pay early and more than once

Interest is calculated on daily balances, so a payment made earlier in the cycle saves more than the same payment on the due date. Paying twice a month also lowers the balance reported to bureaus.

5. Talk to the issuer if you are struggling

If you cannot pay even the minimum, contact the bank before the due date. Many issuers offer restructuring or settlement options. A settlement is better than a default but is reported to bureaus and can affect your score for years, so treat it as a last resort.

When paying the minimum is acceptable

Paying the minimum is better than missing a payment. Missing even the minimum triggers late fees once the account is more than three days past due, a negative entry with credit bureaus, and, if the minimum stays unpaid for 90 days past the due date, classification of the account as a non-performing asset. In a genuine one-month cash crunch, paying the minimum protects your credit record. Just do not let it become a habit.

Key takeaways

• The minimum amount due, commonly 5% of the balance, keeps you clear of late fees but not of interest.
• Paying less than the full bill cancels the interest-free period, so the entire balance and all new purchases attract interest plus 18% GST.
• On ₹1,00,000 at 3.6% a month, minimum-only payments take about 30 years and cost about ₹4.2 lakh in interest and GST.
• A fixed ₹5,000 a month clears the same balance in under 4 years; ₹10,000 clears it in 14 months.
• Stop new spending on the card, fix your payment amount, and consider a cheaper EMI or personal loan to clear the balance.
