Average Daily Balance Method Explained 🎩💳
The Average Daily Balance (ADB) Method is a clever way credit card issuers calculate how much you should pay in interest charges on your outstanding balance. Understanding this method might make you reconsider ordering that extra-large pizza on credit—unless you are planning to sell it at a profit, of course! 🍕💸
Definition
The Average Daily Balance Method calculates the interest charges on credit cards based on the outstanding balance each day during the billing period. Here’s how it works:
- Calculate the daily balances for each day of the billing cycle.
- Add them up and divide by the total number of days in the billing cycle to obtain the average daily balance.
- Multiply this average by the card’s daily periodic interest rate, which is derived from the annual percentage rate (APR) divided by 365 (or 366 in a leap year).
- Multiply this figure by the number of days in the billing period to find the final interest charge.
Formula
Total Interest = (Average Daily Balance) × (Daily Periodic Rate) × (Number of Days in Billing Period)
Example Calculations
Say you have a credit card with an APR of 18%, a billing cycle of 30 days, and the following balances:
- Days 1-10: $1,000
- Days 11-20: $500
- Days 21-30: $0
The ADB would be:
| Day Range | Daily Balance | Number of Days | Contribution to ADB |
|---|---|---|---|
| 1-10 | $1,000 | 10 | $10,000 |
| 11-20 | $500 | 10 | $5,000 |
| 21-30 | $0 | 10 | $0 |
| Total | - | 30 | $15,000 |
Average Daily Balance = Total Contributions / Total Days
= $15,000 / 30 = $500
Next, we find the daily periodic rate:
Daily Periodic Rate = APR / 365 = 0.18 / 365 = 0.00049315
Now, multiplying it all together:
Interest = ADB × Daily Periodic Rate × Days in Billing Cycle
= $500 × 0.00049315 × 30
= $7.40
No one said math was easy, but thankfully, most credit card companies have calculators for this!
ADB Method vs Flat Rate Method Comparison
| Feature | Average Daily Balance Method | Flat Rate Method |
|---|---|---|
| Interest Calculation Basis | Daily balances throughout billing period | Fixed balance during billing period |
| Flexibility in Payment | More favorable if payments are made regularly | Less favorable if balance fluctuates |
| Complexity | More complex to calculate | Simpler and straightforward |
