Credit Card Interest Calculation Formulas
Monthly Payment Calculation (Fixed Term):
M = P × [r(1+r)^n] / [(1+r)^n - 1]
Where:
- M = Monthly payment amount
- P = Principal balance (credit card debt)
- r = Monthly interest rate (Annual rate ÷ 12)
- n = Total number of months
Payoff Time Calculation (Fixed Payment):
n = -log(1 - (P × r) / M) / log(1 + r)
Where:
- n = Number of months to pay off
- P = Principal balance
- r = Monthly interest rate
- M = Fixed monthly payment
Interest Calculation Each Month:
Monthly Interest = Remaining Balance × (Annual Rate / 12)
Principal Payment = Monthly Payment - Monthly Interest
New Balance = Previous Balance - Principal Payment
Total Interest Calculation:
Total Interest = (Monthly Payment × Number of Months) - Original Balance
Credit Card Debt Payoff Strategies & Analysis
1. Debt Avalanche Method
Pay minimums on all cards, then put extra money toward the card with the highest interest rate. This method saves the most money in interest over time.
2. Debt Snowball Method
Pay minimums on all cards, then put extra money toward the card with the smallest balance. This method provides psychological motivation through quick wins.
3. Balance Transfer Strategy
Transfer high-interest debt to a card with a lower promotional rate (often 0% APR). Be aware of transfer fees and the promotional period end date.
4. Debt Consolidation
Combine multiple debts into one loan with a lower interest rate. This simplifies payments and can reduce overall interest costs.
Impact of Extra Payments
Even small additional payments can significantly reduce payoff time and total interest. For example, paying an extra $50/month on a $5,000 balance at 18% APR can save hundreds in interest and shorten payoff time by years.
Minimum Payment Warning
Making only minimum payments (typically 2-3% of balance) can result in decades of payments and thousands in interest. Credit card companies are required to show this information on your monthly statement.
