Credit Card Interest Calculator (Sri Lanka)
See how long it takes to clear your credit card balance and how much interest you'll pay at your current APR and monthly payment.
How this credit card payoff calculator works
The calculator simulates your monthly bill: each month it adds interest at APR/12 to the balance and subtracts your payment. It keeps looping until the balance hits zero. The output is the exact number of months to full payoff plus the total interest paid — the true cost of the balance you're carrying.
Typical credit card rates in Sri Lanka (2026)
Most Sri Lankan credit cards charge 2.5%–3% per month on the outstanding balance, which is 30%–36% AER. Some premium cards go a bit lower on selected transactions, and 0% installment plans on partner merchants are common — but standard revolving credit is always in the 24–36% range.
Tips to escape credit card debt
Never carry a balance you can't clear within 3 months at your current payment rate. Ask your bank for a balance-transfer to a personal loan — the rate drops from 30% to 15–20% overnight. Route large purchases through 0% installment plans instead of paying with the card and revolving. And check Findit.lk for banks offering promotional zero-fee balance transfers and reduced APR for new customers.
The real cost of the minimum payment
Paying the minimum (usually 5% of the outstanding) on a Rs. 200,000 balance at 30% APR takes over 8 years and costs more than Rs. 150,000 in interest. Doubling the minimum cuts it to under 3 years. The math strongly rewards even small extra monthly payments.
Frequently Asked Questions
What is the credit card interest rate in Sri Lanka?
Credit card interest rates in Sri Lanka are typically 24%–36% per annum in 2026 — among the most expensive borrowing available. Most banks charge around 2.5–3% per month on unpaid balances, which compounds to 30–36% AER. This is why clearing the full balance every month matters.
How is credit card interest calculated in Sri Lanka?
If you don't pay the full statement balance by the due date, banks charge interest on the entire outstanding balance from the transaction date — not just from the due date. Interest is computed on the daily balance and billed monthly. Even one late month can wipe out a year of rewards points.
Should I pay minimum or full balance?
Always pay the full balance. Paying only the minimum (usually 5% of the outstanding) means the remaining 95% keeps accruing 30%+ interest. On a Rs. 100,000 balance, paying only the minimum can take 4+ years and cost you nearly double in interest.
Can I convert my credit card balance to a personal loan?
Yes. Most Sri Lankan banks offer balance-transfer or loan-on-card facilities at 15–22% AER — far cheaper than the 30–36% credit card rate. If your card balance is over Rs. 50,000 and you can't clear it this month, converting to a fixed installment loan almost always saves money.
What is the grace period on Sri Lankan credit cards?
Most cards give an interest-free period of 20–52 days if you pay the full statement balance by the due date. Miss even one full payment and you lose the grace period on new transactions too — interest starts accruing from the moment of purchase, not from the due date.
How do I get out of credit card debt fast?
Stop using the card immediately, negotiate a balance transfer to a personal loan at 15–18%, and set up an auto-debit to pay a fixed amount each month. Even Rs. 10,000/month extra on a Rs. 200,000 balance saves you years of interest. Watch bank promotions on Findit.lk — banks periodically offer zero-fee balance transfers.
