A goal, not just a "what if"
Our minimum due calculator answers "what does my current payment cost me." This calculator answers the question the other way round: "I want to be done with this by a certain date — what does that actually require?" Once you commit to a fixed payment and stop adding new spend, the balance behaves like a normal loan, not a shrinking minimum due.
How this calculator works
Minimum-only comparison = simulated month by month, since a percentage-of-balance minimum has no closed-form formula — see the minimum due calculator for exactly how that simulation works.
A worked example
₹80,000 outstanding at 42% p.a., targeting a 12-month payoff:
The required fixed payment is about ₹8,279 a month, for a total interest cost of roughly ₹19,345. Paying only a typical 5%-of-balance minimum (with a ₹200 floor) instead would take about 234 months — nearly 20 years — and cost around ₹1,80,333 in interest. Committing to the 12-month plan here saves over ₹1.6 lakh in interest, simply by fixing the payment instead of letting it shrink.
Choosing a realistic target
A shorter target lowers total interest but raises the required monthly payment; a longer one eases the monthly amount but costs more overall. There's no target that's both fast and cheap on a high-rate balance — the honest trade-off is between what you can actually afford each month and how much interest you're willing to pay for the flexibility.
