Average Outstanding Balance on Credit Cards

Average Outstanding Balance on Credit Cards is a credit-card concept used to evaluate borrowing cost, account terms, rewards, or repayment risk.

The average outstanding balance on credit cards refers to the unpaid, interest-bearing balance averaged over a pre-defined period. This metric is crucial for both consumers and financial institutions as it indicates the amount of debt carried regularly and influences interest calculations.

Daily Balance Method

One way to calculate the average outstanding balance is the daily balance method. Here, the sum of the unpaid balances on the account each day during the billing cycle is divided by the number of days in the cycle.

Formula:

$$ \text{Average Outstanding Balance (Daily Method)} = \frac{\sum\text{Daily Unpaid Balances}}{\text{Number of Days in the Period}} $$

Monthly Balance Method

Alternatively, some institutions use a monthly average. This involves summing the month-end balances over a given period (usually 12 months) and dividing by the number of months.

Formula:

$$ \text{Average Outstanding Balance (Monthly Method)} = \frac{\sum \text{Month-end Balances}}{\text{Number of Months in the Period}} $$

Considerations

  • Interest Calculation: The average outstanding balance is vital for computing interest charges. Higher average balances result in higher interest payments.

  • Credit Score Impact: It affects credit utilization ratios, a key factor in credit scores. Higher average balances can negatively impact credit scores.

Practical Example

Let’s assume a credit card has the following daily balances over a 30-day period:

  • Days 1-10: $1,000
  • Days 11-20: $500
  • Days 21-30: $200

Using the Daily Balance Method:

$$ \text{Sum of Daily Balances} = (10 \times 1000) + (10 \times 500) + (10 \times 200) = 10000 + 5000 + 2000 = 17000 $$
$$ \text{Average Outstanding Balance} = \frac{17000}{30} = \approx 566.67 $$

Real-Life Scenario

For a year, a cardholder’s month-end balances were recorded as:

  • $300, $500, $450, $400, $350, $600, $550, $500, $400, $450, $500, $600

Using the Monthly Balance Method:

$$ \text{Sum of Month-end Balances} = 300 + 500 + 450 + 400 + 350 + 600 + 550 + 500 + 400 + 450 + 500 + 600 = 5550 $$
$$ \text{Average Outstanding Balance} = \frac{5550}{12} = 462.50 $$

Credit Utilization Ratio

This term refers to the percentage of credit used relative to the credit limit available. Calculating the average outstanding balance helps in determining one’s credit utilization ratio over a period.

APR (Annual Percentage Rate)

The average outstanding balance significantly impacts the Annual Percentage Rate (APR) on a revolving credit account, influencing the total interest paid.
