Credit Card Interest Calculator Instructions
Use the calculator to estimate how much interest you may pay on your credit card balance and how long it may take to pay it off.
Have your latest credit card statement available before you begin.
Step 1: Enter Your Credit Card Balance
Enter the amount you currently owe on the card. Include the full outstanding balance, excluding any payments you have already made.
Step 2: Enter Your Interest Rate
Enter the card’s annual percentage rate, or APR. You can find this rate on your credit card statement or through your card issuer’s website.
Step 3: Choose Your Calculation Method
You can calculate your results in either of two ways:
- Enter an average monthly payment to see how long it may take to pay off the balance.
- Enter a target time period to see the monthly payment needed to pay off the balance within that timeframe.
When you enter one option, the other option becomes inactive.
Step 4: Enter Your Monthly Payment or Time Period
For a payment-based estimate, enter the amount you expect to pay each month.
For a time-based estimate, enter the number of months or years in which you want to repay the balance. Use the Months or Years selector to choose the unit.
Step 5: Review Your Results

Which Lenders Have the Best Debt Consolidation Loan Rates?
Finding the right lender could help you save hundreds or even thousands of dollars on interest. The smartest way to know if you’re getting the best personal loan rate is to compare offers from competing lenders.
How Can a Debt Consolidation Loan Save Money on Interest?
A debt consolidation loan is a financial tool that combines high-interest debts, such as credit card balances, into one more manageable loan with a fixed and typically lower annual percentage rate (APR). Here’s how it can help you save money on interest.
Single Monthly Payment
With a debt consolidation loan, you only have to make one monthly payment, simplifying your financial management.
Lower Fixed Interest Rate
Debt consolidation loans often offer lower fixed APRs than the variable and usually higher rates associated with credit cards. This means you’ll pay less in interest over the life of the loan.
Predictable Payments
Fixed interest rates provide predictability in your monthly payments, making it easier to budget and plan for debt repayment.
Faster Debt Payoff
With reduced interest charges, a larger portion of the monthly payment is applied toward reducing the principal balance, helping you pay off your debt faster.
Savings on Interest
The total interest cost over the life of the debt consolidation loan is typically lower than what you’d pay on multiple credit cards with higher rates.
It’s essential to choose a debt consolidation loan with favorable terms, such as a lower interest rate and reasonable fees. Additionally, avoid accumulating new debt on your credit cards while repaying the consolidated loan to benefit from the interest savings fully.
How Can a Balance Transfer Save Money on Interest?
Whether you want to take advantage of better rewards or low-interest credit cards, knowing how much interest you’re paying is crucial for your financial health. If you feel you’re paying too much credit card interest, consider transferring your balance to zero-interest credit cards offered during an introductory period.
A credit card balance transfer is a process that involves moving the outstanding balance from one credit card to another, typically one with a promotional 0% APR for a specific period. Here’s how it can help lower your payments and reduce interest costs:
Lower Interest Rate
When you transfer your balance to a card with a lower APR, you’ll pay less interest on the same amount of debt. This can significantly reduce the cost of carrying a balance.
Introductory 0% APR
Some balance transfer cards offer an introductory period with a 0% APR. During this time, you won’t accrue any interest on the transferred balance, allowing you to focus on paying down the principal debt.
Consolidation
If you have multiple high-interest credit card balances, a balance transfer allows you to consolidate them into a single, more manageable payment. This simplifies debt management and can lead to lower monthly payments.
More Payment Towards Principal
With lower or no interest charges, a larger portion of your payment goes toward reducing the principal balance. This accelerates the debt payoff process.
Predictable Payments
A fixed promotional APR or a lower ongoing APR provides predictability in your monthly payments, making budgeting easier.
Faster Debt Repayment
Reduced interest and larger payments toward the principal can help you pay off your debt faster, saving you money in the long run.
However, it’s important to be aware of balance transfer fees, typically around 3% to 5% of the transferred amount. To maximize the benefits of a balance transfer, aim to pay off the transferred balance within the promotional 0% APR period or before any promotional rate expires.
