How Do They Calculate The Minimum Payment on Credit Cards

How Minimum Payments Work

Minimum payments are the smallest amount you must pay each month to keep your credit card account in good standing. If you don't pay at least this amount, your issuer may charge you late fees, raise your interest rate, or even close your account.

The minimum payment is typically calculated as a percentage of your current balance, with a minimum dollar amount to ensure you pay something even if your balance is very low. This percentage is usually between 2% and 3% of your balance, but it can vary depending on your issuer and the type of card you have.

Formula for Minimum Payment

The basic formula for calculating the minimum payment is:

Where:

• Current Balance - The total amount owed on your credit card
• Minimum Payment Percentage - The percentage of your balance that must be paid (typically 2-3%)
• Minimum Payment Amount - The smallest fixed amount that must be paid (usually $5-$10)

For example, if your balance is $1,000, the minimum payment percentage is 2.5%, and the minimum payment amount is $10, the calculation would be:

Interest Charges

Minimum payments include interest charges on your balance. The interest is calculated daily and added to your balance, which is then used to calculate the next month's minimum payment.

The formula for calculating interest charges is:

Where:

• Daily Balance - The average daily balance for the billing period
• Daily Interest Rate - The annual percentage rate (APR) divided by 365

This daily interest is added to your balance, increasing the amount you owe and the minimum payment for the next month.

Balance Transfers

When you transfer a balance from another credit card, the minimum payment calculation changes. The issuer typically sets a minimum payment percentage for the transferred balance, which may be higher than the standard rate.

For balance transfers, the formula is similar but may include a different minimum payment percentage:

The transfer minimum percentage is usually higher (often 3-5%) to encourage you to pay off the transferred balance quickly.

Payment Examples

Let's look at two examples to illustrate how minimum payments are calculated.

Example 1: Standard Credit Card

You have a credit card with:

• Current balance: $1,500
• Minimum payment percentage: 2.5%
• Minimum payment amount: $10

The calculation would be:

So your minimum payment would be $47.50.

Example 2: Balance Transfer

You transfer a balance of $2,000 with:

• Transfer minimum percentage: 3%
• Minimum payment amount: $15

The calculation would be:

So your minimum payment for the transferred balance would be $75.
