This calculator helps you understand how a $10 interest payment affects your $1000 credit card balance. It shows the remaining balance after the payment and the interest charged.

How the calculator works

When you make a payment on your credit card, the interest is calculated on the remaining balance. The calculator shows how much interest is charged and what your new balance will be after your payment.

Note: This calculator assumes the interest is calculated on the full balance before your payment. Some cards may calculate interest differently.

Key concepts

Interest is calculated on the outstanding balance before your payment
The payment reduces your balance, but interest continues to accrue
The remaining balance after payment is what you'll pay interest on next period

Example calculation

Let's say you have a $1000 credit card balance with 20% APR. If you make a $10 payment, here's what happens:

Step	Calculation	Result
1. Calculate interest	$1000 × 20% = $200	$200 interest
2. Apply payment	$1000 + $200 - $10 = $1190	$1190 new balance

After making the $10 payment, your new balance is $1190, and you'll owe $200 in interest next period.

Formula used

The calculator uses this formula to determine the new balance:

New Balance = (Original Balance × (1 + Interest Rate)) - Payment Amount

Where:

Original Balance = Your current credit card balance
Interest Rate = The APR (Annual Percentage Rate) converted to a decimal
Payment Amount = The amount you're paying toward the balance

Frequently asked questions

How is interest calculated on my credit card?: Interest is typically calculated daily on the average daily balance, then applied monthly. Some cards may use a different method.
Does making a payment reduce my interest?: No, making a payment only reduces your balance. Interest continues to accrue on the remaining balance.
How can I lower my credit card interest?: You can pay more than the minimum, transfer balances to a 0% APR card, or negotiate with your card issuer.
Is the calculator accurate for all credit cards?: The calculator provides an estimate. For precise calculations, check your card's specific terms and use your card issuer's calculator.
