Formula Used
The calculator uses the following formula to estimate interest charges:
Interest Calculation
Interest = (Current Balance × Daily Interest Rate × Number of Days in Billing Cycle) - (Average Monthly Payment × Number of Payments)
Where Daily Interest Rate is calculated as (Annual Percentage Rate / 365)
Minimum payment is calculated as the greater of 2% of the current balance or the minimum payment amount specified by your card.
Worked Example
Let's calculate interest for a $3,000 balance with a 15.99% APR and $250 monthly payments:
- Daily interest rate = 15.99% / 365 ≈ 0.04376%
- Number of days in billing cycle = 30
- Interest = ($3,000 × 0.0004376 × 30) - ($250 × 1) = $40.68 - $250 = -$209.32
This example shows a negative interest charge, meaning you're paying down your balance faster than the interest is accruing. The actual result will vary based on your specific terms and payment history.
