Daily Interest Formula:
| From: | To: |
The Credit Card Daily APR Calculator computes the daily interest charges on your credit card balance using the daily periodic rate derived from your annual percentage rate (APR). This helps you understand how much interest you'll accrue during a billing cycle.
The calculator uses these formulas:
Where:
Explanation: The calculator first converts your APR to a daily rate, then multiplies by your average balance and the number of days to determine your interest charges.
Details: Understanding how daily interest accrues helps you make informed decisions about credit card payments and balance management. Even small daily charges can add up significantly over time.
Tips: Enter your card's APR (found in your cardholder agreement), your average daily balance (from your statement), and the number of days in your billing cycle (typically 28-31 days).
Q1: Is the DPR calculation the same for all credit cards?
A: Most cards use 365 days, but some may use 360. Check your cardholder agreement for specifics.
Q2: How can I reduce my interest charges?
A: Pay your balance in full each month, make payments early in the billing cycle, or negotiate a lower APR with your issuer.
Q3: Does this include compounding interest?
A: This calculates simple daily interest. Some cards compound interest daily, which would result in slightly higher charges.
Q4: Why is my actual interest sometimes different?
A: Your actual ADB may vary from your estimate, or your card may have different calculation methods for purchases vs cash advances.
Q5: How accurate is this calculator?
A: It provides a good estimate, but for exact figures, refer to your credit card statement or issuer's calculations.
