## Debt Payoff Methods

### Debt Avalanche (Mathematically Optimal)
- Pay minimums on all debts
- Extra payments to highest interest rate first
- Saves the most money on interest
- Best for disciplined, numbers-focused people

### Debt Snowball (Psychologically Optimal)
- Pay minimums on all debts
- Extra payments to smallest balance first
- Quick wins for motivation
- Best for people who need momentum

### Hybrid Approach
- Start with smallest debt for quick win
- Then switch to highest interest
- Balance of motivation and savings

## Key Concepts

### Minimum Payments
- Cover interest + small principal
- Keeps accounts current
- Very slow progress alone

### Extra Payments
- Applied directly to principal
- Reduces total interest paid
- Accelerates payoff significantly

### Interest Calculation
- Daily: Balance × (APR/365) × days
- Monthly: Balance × (APR/12)
- Higher rate = more expensive debt
