Credit Card Payoff — How Long Will It Take & How Much Interest Will You Pay?
Calculate how long it takes to pay off credit card debt and total interest paid. Learn strategies to pay off faster: snowball, avalanche, and balance transfer methods.
Credit card debt compounds aggressively. Paying only the minimum can keep you in debt for decades. Here’s the math and how to escape.
The minimum payment trap
Credit card companies typically set minimum payments at 2–5% of the balance. On a ₹1 lakh balance at 36% APR with 2% minimum:
- Minimum payment month 1: ₹2,000
- Interest charged: ₹3,000
- Balance actually increases because minimum < interest
Even at 5% minimum (₹5,000), payoff takes 2+ years with ₹40,000+ in interest.
The payoff formula
Months to Payoff = −log(1 − (Balance × MonthlyRate ÷ Payment)) ÷ log(1 + MonthlyRate)
Total Interest = (Monthly Payment × Months) − Original BalancePayoff strategies
1. Debt Avalanche (mathematically optimal)
Pay minimums on all cards, put extra money toward the highest interest rate card first. Saves the most money.
2. Debt Snowball (psychologically effective)
Pay off the smallest balance first. The quick wins build momentum. Less optimal mathematically but higher success rate.
3. Balance Transfer
Move debt to a 0% introductory APR card. You get 6–18 months interest-free to pay down principal. Watch for transfer fees (2–5%).
The power of paying more
On ₹1 lakh at 36% APR:
| Monthly Payment | Months to Payoff | Total Interest |
|---|---|---|
| ₹5,000 | 28 months | ₹38,000 |
| ₹8,000 | 15 months | ₹18,000 |
| ₹12,000 | 10 months | ₹11,000 |
| ₹20,000 | 6 months | ₹6,000 |
Every extra ₹1,000/month saves you thousands in interest.
