How to use
- Enter the average daily balance from your statement.
- Enter the card APR (in Pakistan usually 35–45%).
- Enter the billing cycle days and how many months the balance will stay unpaid.
- See the daily, cycle, and monthly interest.
Tips
- Compare the daily charge to your minimum payment: if the interest alone is close to the minimum, the balance barely moves.
- Paying a week earlier in the billing cycle cuts the average daily balance and the interest with it.
- Balance transfers can help, but read the transfer fee and the revert rate first.
- The estimate assumes the balance stays unpaid; partial payments lower the charge.
Note
Banks use the average daily balance method, and you only get a grace period when the previous balance is paid in full. Late fees and cash advance charges are not included.
