Minimum due keeps the account current; it does not make the debt cheap
A credit-card statement can show a relatively small minimum amount due next to a much larger total amount due. Paying the minimum may avoid being treated the same way as a missed payment under the issuer’s terms, but the remaining balance can continue revolving and attracting interest.
RBI’s card directions specifically require issuers to warn that making only the minimum payment every month can stretch repayment over months or years with consequential interest.
Why the debt can shrink slowly
Consider a ₹1 lakh balance with a high APR. Interest is charged each billing cycle. If the minimum payment is a percentage of the balance, the rupee payment can also decline as the balance declines.
That creates a feedback loop:
- the balance attracts interest,
- the minimum payment pays that interest plus some principal,
- the balance falls,
- the next minimum payment may also fall,
- principal reduction remains slow.
New spending can stop the balance from falling
If you continue adding purchases while revolving the old balance, the monthly payment has to cover both new spending and interest before it meaningfully reduces old principal.
That is why the FinPockett calculator has an optional new-spending input. If payment is too low to reduce principal under the entered assumptions, it gives a warning rather than producing a misleading payoff date.
Compare three modes
| Mode | What the calculator assumes |
|---|---|
| Minimum payment | payment tracks a percentage assumption |
| Fixed monthly payment | same rupee amount each month |
| Pay in full | balance is cleared in that cycle in the simplified model |
A higher fixed payment usually shortens repayment dramatically because more of each payment reaches principal earlier.
Frequently asked questions
Is the minimum amount due an RBI-set percentage?
No. Issuer formulas vary. Use the percentage shown in your card terms or statement for a closer estimate.
Does paying minimum due stop interest?
No. The unpaid revolving balance can continue attracting interest under the issuer’s terms.
What if my payment is less than monthly interest plus new purchases?
The balance may not reduce. The calculator warns about that condition.
Does the calculator include every fee and GST line?
No. It models balance, interest and payment behaviour. Check the issuer statement for fees and tax treatment.
