Total Cost Equation:
From: | To: |
This calculator helps you determine the true annual cost of your credit card by combining both the interest you pay and the annual fee. Understanding this total cost can help you make better financial decisions when comparing credit cards.
The calculator uses a simple equation:
Where:
Explanation: The equation simply adds together all the costs associated with using the credit card for one year.
Details: Many consumers focus only on annual fees or only on interest rates, but the true cost of a credit card includes both. This calculation helps you compare cards more accurately and make informed financial decisions.
Tips: Enter your estimated annual interest payments (based on your expected balance and APR) and the card's annual fee. Both values should be in dollars and can include cents.
Q1: Should I include balance transfer fees?
A: If you're calculating costs for a specific year and did balance transfers, you should include those fees as part of your total costs.
Q2: What about rewards and cash back?
A: This calculator shows costs only. You may want to subtract any rewards you earn to get your net cost.
Q3: How can I estimate my annual interest?
A: Multiply your average daily balance by your daily periodic rate (APR/365), then multiply by 365 days.
Q4: Are there cards with no annual fee?
A: Yes, many cards have no annual fee, which makes their total cost equal to just the interest paid.
Q5: When does a high annual fee make sense?
A: When the card's benefits (travel credits, lounge access, etc.) outweigh the fee, or if you spend enough to earn substantial rewards.
