About Credit Card Interest

Finance charges are the interest you pay when you carry a balance on your credit card. Most cards calculate interest daily based on your average daily balance during the billing cycle.

Note: If you pay your balance in full by the due date, you typically won't incur any finance charges. This calculator assumes you carry the same balance throughout the entire billing cycle.

This calculator helps estimate your potential finance charges. Print Results

What is a Finance Charge?

A finance charge is the total cost of borrowing money, including interest, fees, and other costs associated with a loan or credit. It is commonly applied to credit cards, personal loans, mortgages, and other forms of credit. Lenders and financial institutions use finance charges to compensate for the risk and opportunity cost of lending money.

How to Calculate Finance Charges

The method of calculating finance charges depends on the type of credit or loan. Below are common calculation methods:

1. Credit Card Finance Charges

Credit card issuers use different methods to compute finance charges, including:

• Average Daily Balance Method (Most Common)

• Adjusted Balance Method

• Previous Balance Method

• Daily Balance Method

Example: Average Daily Balance Method

1. Determine the Daily Balance:
   For each day in the billing cycle, calculate:

   $$\text{Daily Balance}=\text{Previous Balance}+\text{Purchases}-\text{Payments/Credits}$$

2. Compute the Average Daily Balance (ADB):

   $$\text{ADB}=\frac{\text{Sum of Daily Balances}}{\text{Number of Days in Billing Cycle}}$$

3. Calculate the Finance Charge:

   $$\text{Finance Charge}=\text{ADB}\times \left(\frac{\text{APR}}{365}\right)\times \text{Number of Days in Billing Cycle}$$

2. Loan Finance Charges (Simple Interest)

For personal loans or auto loans, finance charges are often calculated using simple interest:

$$\text{Finance Charge}=\text{Principal}\times \text{Interest Rate}\times \text{Time (in years)}$$

3. Mortgage Finance Charges

Mortgages use amortization, where interest is front-loaded. The finance charge is the total interest paid over the loan term.

Finance Charge Calculator Formula

The general formula for calculating finance charges is:

$$\text{Finance Charge}=\text{Principal}\times (\frac{\text{APR}}{100}\times \frac{\text{Time Period}}{365})+\text{Fees}$$

Variables Needed:

Variable	Description
Principal	The initial loan/credit amount
APR (%)	Annual Percentage Rate (interest rate + fees)
Billing Cycle (Days)	Duration for which the charge is calculated
Average Daily Balance	For credit cards, the average owed per day
Additional Fees	Late fees, service charges, etc.

Example Calculation

Credit Card Finance Charge

• Billing Cycle: 30 days

• APR: 18%

• Average Daily Balance: $1,000

Step 1: Convert APR to daily rate

$$\text{Daily Rate}=\frac{18\mathrm{\%}}{365}=0.0493\mathrm{\%}\text{ per day}$$

Step 2: Calculate Finance Charge

$$\text{Finance Charge}=\mathrm{\$}1,000\times 0.000493\times 30=\mathrm{\$}14.79$$

Total Finance Charge for the month = $14.79
