Monthly Finance Charge Formula

The formula for calculating the monthly finance charge is:

Monthly Finance Charge = (Average Daily Balance x Daily Periodic Rate x Number of Days in the Cycle) / 12

Breaking Down the Formula

Let's break down the formula into its individual components:

Average Daily Balance: This is the average balance of the account over the billing cycle. It is calculated by adding up the beginning and ending balances and dividing by 2.
Daily Periodic Rate: This is the interest rate charged per day, expressed as a decimal. For example, a 12% annual interest rate would be 0.12 / 365 = 0.000329 (daily periodic rate).
Number of Days in the Cycle: This is the number of days in the billing cycle, which can vary from 28 to 31 days.

Applying the Formula to a Real-World Scenario

Let's apply the formula to a real-world scenario:

Average Daily Balance: $20
Daily Periodic Rate: 0.04% (or 0.0004 as a decimal)
Number of Days in the Cycle: 30

Plugging these values into the formula, we get:

Monthly Finance Charge = ($20 x 0.0004 x 30) / 12 Monthly Finance Charge = $0.06
