Introduction

When it comes to managing credit card debt, understanding how finance charges are calculated is crucial. In this article, we will explore a real-life example of a 30-day billing cycle and how finance charges are computed using the average daily balance method. We will use the transactions of Andrew, a credit card holder, to illustrate this concept.

The 30-Day Billing Cycle

A 30-day billing cycle is a common practice used by credit card companies to calculate finance charges. This cycle typically starts on the day the credit card statement is issued and ends on the day before the next statement is issued. In Andrew's case, his credit card has a 30-day billing cycle, which means that his statement is issued on the 1st of each month and is due on the 30th of the same month.

Transactions in March

The table below shows the transactions that Andrew made in March:

Date	Transaction Type	Balance
1st	Payment	$1,000
5th	Purchase	$500
10th	Purchase	$200
15th	Payment	$300
20th	Purchase	$100
25th	Purchase	$50
28th	Payment	$200

Calculating the Average Daily Balance

To calculate the average daily balance, we need to first calculate the daily balance for each day in March. We will then take the average of these daily balances to determine the average daily balance for the month.

Date	Daily Balance
1st	$1,000
2nd	$1,000
3rd	$1,000
4th	$1,000
5th	$1,500
6th	$1,500
7th	$1,500
8th	$1,500
9th	$1,500
10th	$1,700
11th	$1,700
12th	$1,700
13th	$1,700
14th	$1,700
15th	$1,000
16th	$1,000
17th	$1,000
18th	$1,000
19th	$1,000
20th	$1,200
21st	$1,200
22nd	$1,200
23rd	$1,200
24th	$1,200
25th	$1,250
26th	$1,250
27th	$1,250
28th	$1,050
29th	$1,050
30th	$1,050

Calculating the Average Daily Balance

To calculate the average daily balance, we need to add up the daily balances and divide by the number of days in the month.

Average Daily Balance = (1,000 + 1,000 + 1,000 + 1,000 + 1,500 + 1,500 + 1,500 + 1,500 + 1,500 + 1,700 + 1,700 + 1,700 + 1,700 + 1,700 + 1,000 + 1,000 + 1,000 + 1,000 + 1,000 + 1,200 + 1,200 + 1,200 + 1,200 + 1,200 + 1,250 + 1,250 + 1,250 + 1,250 + 1,050 + 1,050 + 1,050) / 31

Average Daily Balance = $1,243.87

Calculating the Finance Charge

To calculate the finance charge, we need to multiply the average daily balance by the APR and the number of days in the billing cycle.

Finance Charge = Average Daily Balance x APR x Number of Days

Finance Charge = $1,243.87 x 0.1660 x 30

Finance Charge = $63.49

In this article, we have explored a real-life example of a 30-day billing cycle and how finance charges are computed using the average daily balance method. We have used the transactions of Andrew, a credit card holder, to illustrate this concept. By understanding how finance charges are calculated, we can better manage our credit card debt and avoid unnecessary fees.
