Core Formulas
- - Monthly Interest = Balance × (APR / 12)
- - Daily Compounding = Balance × (APR / 365)
- - Minimum Payment = max($25, Balance × %)
- - Remaining Balance = Previous Balance + Interest - Payment
- - Total Interest = Sum of all monthly interest charges
Repayment Strategies
- - Minimum: Slowest, highest total interest
- - Fixed: Constant payment for predictable payoff
- - Snowball: Pay smallest balance first (motivation boost)
- - Avalanche: Pay highest APR first (most cost-efficient)
- - Hybrid: Mix of balance + APR optimization
- - Custom: User-defined priority order
Balance Transfer Logic
- - Intro APR applies for limited months
- - After promo period → regular APR applies
- - Transfer fee increases initial balance
- - Best used if debt cleared within promo period
Tax Impact
- - Business debt interest may be partially deductible
- - Student loan interest has deduction limits
- - Federal + state tax brackets affect savings
- - Net Cost = Total Interest - Tax Savings
Opportunity Cost
- - Money used for debt could be invested instead
- - Future Value = Payment × (1 + savings rate)^time
- - Higher interest debt → prioritize payoff over investing
Credit Score Impact
- - Utilization Ratio = Balance / Credit Limit
- - Below 30% improves score
- - Faster payoff → positive score impact
- - High balances → negative impact
