One card, several balances
Treating these as one number is the root of most surprises. NiyamPay models them as separate buckets so you can see which part of the card is actually costing you money.
- Revolving balance — what was carried forward when a previous statement was not paid in full. Interest accrues on it daily.
- Fresh purchases — new spends in the current cycle. These are interest-free only while the account carries no revolving balance.
- Cash advance — cash withdrawn on the card. Interest usually starts on day one, with no interest-free period, and a withdrawal fee applies.
- Card EMI — a purchase converted into instalments at its own rate, sitting on the same card but behaving like a loan.
Interest, and the GST charged on it
Card interest in India is typically quoted as a monthly rate and accrues on the daily outstanding balance, which is why the charge changes with the timing of your payment, not just its size.
GST at 18% is applied to the interest and to most fees. It is a real part of the cost of the debt, so NiyamPay includes it in interest calculations rather than showing a pre-tax figure that nobody actually pays.
Illustrative example
- Revolving balance
- ₹1,00,000
- Monthly interest rate
- 3.5%
- Interest for the cycle
- ₹3,500
- GST at 18% on that interest
- ₹630
- Total cost for the cycle
- ₹4,130
Illustrative only. Your card's rate, cycle length, fees and daily balances will produce a different figure.
Why paying only the minimum due is expensive
The minimum due is typically a small percentage of the outstanding balance, subject to a floor. Paying it keeps the account current and avoids a late fee — that is all it is designed to do.
Because the minimum moves with the balance, it falls as the balance falls, which stretches repayment out for years. And when the minimum is close to the interest charged, almost none of the payment reduces what you owe.
- Paying the minimum protects your account status, not your money
- The interest-free period on new purchases is lost while a revolving balance exists
- A balance that barely moves month to month is usually a minimum-payment pattern, not bad luck
Negative amortisation on a card
If a cycle's payment is less than the interest and charges added in that cycle, the balance rises. On a card carrying a cash advance and a high revolving balance this can happen while you are paying every month, on time.
NiyamPay flags this condition directly, on the debt and in your plan, so it is visible before months of payments go into it.
Where your payment actually lands
A payment is not applied wherever you would prefer. Allocation follows a set order across the card's components, and that order determines whether an expensive balance shrinks or an inexpensive one does.
NiyamPay shows the allocation for every payment you record — how much went to interest and GST, how much to each bucket — so the ledger explains itself rather than presenting a single opaque total.
FAQ
Common questions
Is GST charged on credit card interest in India?
Yes. GST at 18% is generally applied to interest and to most card fees, so the real cost of carrying a balance is higher than the interest figure alone.
What happens if I pay only the minimum due?
Your account stays current and you avoid a late fee, but the balance reduces very slowly and interest keeps accruing, so total repayment can stretch over years.
Why did my card balance go up even though I paid?
If the payment was smaller than the interest and charges for that cycle, the balance grows. This is negative amortisation and NiyamPay warns you when a planned payment would cause it.
Does NiyamPay recommend credit cards or balance transfers?
No. NiyamPay does not recommend, compare or distribute any financial product. It only helps you understand and plan the debt you already have.
