# Previous Balance Method Of Calculating Finance Charges – how it works

Have you paid a finance charge before? Do you know how your credit card issuer calculates your finance charges? If you have ever missed a credit card payment, you would have noticed a finance charge on your billing statement. This finance charge is calculated in different ways.
One of the ways of calculating finance charges is the Previous Balance Method. You can check your recent billing statement to know if your credit issuer uses this method or call customer service. If you understand how the previous balance method is calculated, you will be able to estimate your finance charges.

## How it Works

The previous balance method of calculating finance charges uses the balance at the beginning of the billing cycle to calculate your finance charge for that billing cycle. This means none of the activity that takes place with your account during that particular monthly billing cycle will affect your finance charge costs.

The benefit of using this method is that any changes made to your account during the billing cycle won’t lead to a higher finance charge. However, on the downside, payments you make during the billing cycle also won’t reduce your balance and, consequently, your finance charges.

If your credit card issuer uses the previous balance method to calculate your finance charge, keep in mind that your balance carries over to the next billing cycle, so what you do this month affects your finance charge for next month.

The previous balance method can be more expensive than other types of finance charge calculation methods. If your credit card issuer uses this method, you can minimize the amount you pay in finance charges each month by paying more money to the account than the amount you charge during the month.

### Finance Charge Calculation Example

The following shows an example of a finance charge calculated using the previous balance method. If,

APR (Annual Percentage Rate) = 14 percent

Periodic rate = 1.17 percent (APR / 12 months)

Days in billing cycle = 30

Beginning balance = \$1,000

Payment made on 16th day = \$100

Charge made on 20th day = \$50

Ending balance = \$950

Finance charge = Previous balance * periodic rate

= \$1,000 * .0117

= \$11.70 finance charge

### Compared to the Average Daily Balance Method

Many credit card issuers use the average daily balance method to calculate finance charges. With this method, the credit card issuer totals your balance each day of the billing cycle. Then calculates the average of that total.

If your credit card issuer used the average daily balance method, your finance charge with the same details as the scenario above would be slightly lower at \$11.40. Assuming you made payments and purchases on the same day of the billing cycle.

If you choose to carry a balance on your credit card, look for a card that comes with a low APR. Ask which interest calculation method the company uses. And make your card choice based on your spending patterns and the interest-calculation method that most favors your spending and payment patterns.

You can avoid finance charges regardless of which method your credit card issuer uses by paying your credit card balance in full each month.
