Comparing multiple credit cards can be complex, but this calculator simplifies the process by allowing you to input key details for up to three cards and instantly see a side-by-side comparison of interest rates, fees, and payment options.
How to Use This Calculator
To use the Multiple Card Calculator:
- Enter the details for each credit card you want to compare in the right sidebar.
- For each card, provide the annual percentage rate (APR), annual fee, and any other relevant information.
- Click "Calculate" to see the comparison results.
- Review the results to determine which card is most suitable for your needs.
The calculator will display the total cost of each card over a 12-month period, including interest and fees, allowing you to make an informed decision.
Formula Used
Total Cost Calculation
The total cost of each card is calculated using the following formula:
Total Cost = (APR × Balance) + Annual Fee
Where:
- APR is the annual percentage rate
- Balance is the average monthly balance
- Annual Fee is the yearly fee for the card
This formula provides a simple way to compare the cost of different credit cards over a 12-month period.
Worked Example
Let's consider two credit cards:
| Card | APR | Annual Fee | Average Balance |
|---|---|---|---|
| Card A | 18% | $95 | $1,500 |
| Card B | 21% | $0 | $1,500 |
Using the formula:
- For Card A: (0.18 × $1,500) + $95 = $270 + $95 = $365
- For Card B: (0.21 × $1,500) + $0 = $315 + $0 = $315
In this example, Card B is the more cost-effective option.
Card Comparison Table
Here's a sample comparison table for three hypothetical credit cards:
| Card | APR | Annual Fee | Rewards | Total Cost (12 months) |
|---|---|---|---|---|
| Premium Rewards | 15% | $95 | 3% cash back | $225 |
| Student Card | 18% | $0 | 1% points | $270 |
| Business Card | 20% | $120 | 2% travel credits | $360 |
This table shows that the Student Card offers the best balance of low cost and rewards.
