Previous Balance Method: Definition and Usage

The Previous Balance Method utilizes the balance at the beginning of the billing cycle to calculate interest, often leading to higher charges compared to the average daily balance method.

The Previous Balance Method is a billing method used by some credit card issuers to calculate the interest charges on an outstanding balance. In this method, the interest is determined based on the balance at the start of the billing cycle, rather than the balance at the end of the billing cycle or the average balance throughout the cycle.

Calculation and Implications

How Interest is Calculated

In the previous balance method, the following formula is typically used to calculate interest:

$$ \text{Interest} = \text{Previous Balance} \times \left(\frac{\text{Annual Percentage Rate (APR)}}{12}\right) $$

For example, if the beginning balance is $1,000 and the annual percentage rate (APR) is 18%, the monthly interest would be:

$$ \text{Interest} = 1000 \times \left(\frac{18\%}{12}\right) = 1000 \times 0.015 = 15 $$

Higher Interest Charges

Since this method relies on the balance at the start of the billing cycle, it can result in higher interest charges, particularly if payments and new charges reduce the balance during the billing cycle. This makes it less favorable for consumers compared to methods like the average daily balance method.

Example

Consider a credit card with a previous balance of $1,000, an APR of 18%, and a billing cycle with 30 days. If you make a payment of $500 on the 10th day, under the previous balance method, the interest for the cycle would still be calculated as:

$$ 1000 \times 0.015 = 15 $$

In contrast, if the average daily balance method were used, the interest would account for the payment made during the billing cycle, potentially lowering the charge.

Comparison with Other Methods

Average Daily Balance Method

In the average daily balance method, interest is calculated based on the average balance over the billing cycle. This method typically results in lower interest charges if payments are made during the cycle.

Adjusted Balance Method

The adjusted balance method calculates interest based on the balance at the end of the billing cycle after payments have been deducted. This often results in the lowest interest charges.

FAQs

Is the Previous Balance Method Common?

No, the previous balance method is less common compared to the average daily balance method because it tends to be less favorable for consumers.

Can I Avoid Interest Charges with the Previous Balance Method?

Yes, if you pay off your entire balance from the previous billing cycle, you can avoid interest charges entirely.

Why Do Some Credit Card Issuers Use This Method?

Some issuers prefer this method as it can produce higher interest revenues and is simpler to administer.

Summary

The Previous Balance Method calculates interest based on the balance at the start of the billing cycle.
