1. What is the Credit Card Savings Formula?

The Credit Card Savings Formula calculates the difference in interest payments between two different APR rates or repayment plans. It helps consumers understand potential savings from negotiating lower rates or changing payment strategies.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( I_{old} \) — Interest paid with original APR (in dollars)
• \( I_{new} \) — Interest paid with new APR or payment plan (in dollars)
• \( S \) — Total savings (in dollars)

Explanation: This straightforward calculation shows the monetary benefit of reducing your credit card interest rate or paying off debt faster.

3. Importance of Credit Card Savings Calculation

Details: Understanding potential savings can motivate consumers to negotiate better rates or adjust repayment strategies, potentially saving hundreds or thousands in interest payments.

4. Using the Calculator

Tips: Enter the total interest you would pay under your current plan and the projected interest under the new plan. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How do I estimate I_old and I_new?
A: Use online credit card calculators to project total interest for different APRs or payment amounts before and after changes.

Q2: Does this include balance transfer fees?
A: No, this only calculates interest differences. Add any fees to I_new for complete comparison.

Q3: What's a good savings amount?
A: Any savings is beneficial, but significant savings (20%+ of original interest) often justify changing cards or repayment plans.

Q4: Can this be used for other loans?
A: Yes, the same principle applies to any loan where you're comparing interest payments under different terms.

Q5: How accurate is this calculation?
A: It's precise for fixed-rate comparisons but assumes no additional charges/purchases on the card.
