APR, or Annual Percentage Rate, is the interest rate charged on a credit card balance. It's a crucial factor to consider when using a credit card, as it can significantly impact the amount you owe. In this article, we'll delve into the world of APR and billing cycles, using Yolanda's credit card transactions as a case study.
Yolanda's Credit Card Transactions in November
| Date | Amount ($) | Transaction Type |
|---|---|---|
| 1st | 100 | Purchase |
| 5th | 200 | Purchase |
| 10th | 50 | Payment |
| 15th | 300 | Purchase |

Calculating APR and Billing Cycle
Yolanda's credit card has an APR of 16.22% and a billing cycle of 30 days. To understand how this affects her credit card balance, we need to calculate the daily periodic rate (DPR). The DPR is calculated by dividing the APR by 365 (days in a year).
DPR = APR / 365 = 16.22% / 365 = 0.0444 (daily periodic rate)
Daily Balance Calculation
To calculate the daily balance, we need to multiply the previous day's balance by (1 + DPR). We'll use this formula to calculate the daily balance for each day in November.
| Date | Daily Balance |
|---|---|
| 1st | 0 |
| 2nd | 0 + (100 * 0.0444) = 4.44 |
| 3rd | 4.44 + (100 * 0.0444) = 8.88 |
| 4th | 8.88 + (100 * 0.0444) = 13.32 |
| 5th | 13.32 + (200 * 0.0444) = 27.68 |
| 6th | 27.68 + (200 * 0.0444) = 42.12 |
| 7th | 42.12 + (200 * 0.0444) = 56.56 |
| 8th | 56.56 + (200 * 0.0444) = 71 |
| 9th | 71 + (200 * 0.0444) = 85.44 |
| 10th | 85.44 - 50 = 35.44 |
| 11th | 35.44 + (200 * 0.0444) = 50.88 |
| 12th | 50.88 + (200 * 0.0444) = 66.32 |
| 13th | 66.32 + (200 * 0.0444) = 81.76 |
| 14th | 81.76 + (200 * 0.0444) = 97.2 |
| 15th | 97.2 + (300 * 0.0444) = 141.48 |
| 16th | 141.48 + (300 * 0.0444) = 186.76 |
| 17th | 186.76 + (300 * 0.0444) = 232.04 |
| 18th | 232.04 + (300 * 0.0444) = 277.32 |
| 19th | 277.32 + (300 * 0.0444) = 322.6 |
| 20th | 322.6 + (150 * 0.0444) = 373.14 |
| 21st | 373.14 + (150 * 0.0444) = 423.58 |
| 22nd | 423.58 + (150 * 0.0444) = 474.02 |
| 23rd | 474.02 + (150 * 0.0444) = 524.46 |
| 24th | 524.46 + (150 * 0.0444) = 574.9 |
| 25th | 574.9 - 100 = 474.9 |
| 26th | 474.9 + (200 * 0.0444) = 579.34 |
| 27th | 579.34 + (200 * 0.0444) = 683.78 |
| 28th | 683.78 + (200 * 0.0444) = 788.22 |
| 29th | 788.22 + (200 * 0.0444) = 892.66 |
| 30th | 892.66 + (200 * 0.0444) = 997.1 |
