Estimate how many months it takes to pay off a credit card balance at a fixed monthly payment.
Each month, interest accrues on the remaining balance (APR/12), then your payment is applied. We simulate this month-by-month until the balance reaches zero.
Paying a fixed amount every month toward a credit card balance sounds straightforward, but the payoff timeline is highly sensitive to the interest rate, which on Indian credit cards commonly runs 3-3.5% per month — 36-42% per year — among the most expensive consumer credit available. At those rates, a payment only slightly above the minimum due can take years to clear a balance, because so much of each payment is consumed by interest before any of it reduces principal; a payment that looks reasonable on paper can still leave the balance barely moving month to month if it is too close to the interest accruing.
If you are carrying balances on more than one card, the order you pay them off in changes the total interest paid: the avalanche method (paying extra toward the highest-interest card first, minimums on the rest) minimizes total interest mathematically, while the snowball method (paying off the smallest balance first regardless of rate) sacrifices some interest savings for the psychological win of closing an account sooner — either is far better than spreading extra payments evenly across all cards, which extends every balance's life unnecessarily. Critically, continuing to spend on a card while trying to pay it off undoes the plan entirely, since new purchases start accruing interest immediately in most cases once a balance is already carried.
Because Indian credit card interest typically runs 3-3.5% per month (36-42% annualized), a payment that is only somewhat above the minimum due can be mostly consumed by interest before any of it reduces the principal — the gap between your payment and the accruing interest is what actually determines how fast the balance falls.
The avalanche method — extra payments toward the highest-interest-rate card first, minimums on the rest — minimizes total interest paid mathematically. The snowball method (smallest balance first) can be worth the small extra interest cost if the quicker win keeps you motivated to stick with the plan; either beats spreading payments evenly across all cards.
Significantly — new purchases on a card already carrying a balance typically start accruing interest immediately, with no grace period, since the grace period on new purchases usually only applies when the previous statement was paid in full. Continuing to spend while paying down a balance can keep the total owed roughly flat even as payments are made.
Often yes if a genuinely lower rate is available, since a balance transfer or a personal loan used to pay off high-interest credit card debt can cut the interest rate dramatically — but check for balance transfer fees and confirm the new rate and terms are actually better before committing, since some transfer offers include a low introductory rate that resets higher after a set period.
