💡 Debt Payoff Strategies

🏔️ Debt Avalanche

Pay minimums on all debts, put extra toward highest interest rate. Saves most money mathematically.

⛄ Debt Snowball

Pay minimums on all debts, put extra toward smallest balance. Provides psychological wins and momentum.

💰 Extra Payment Sources

Tax refunds, bonuses, side hustle income, spending cuts, or windfalls can accelerate payoff significantly.

📊 Balance Transfers

Consider 0% APR balance transfer cards for high-interest debt, but have a payoff plan before rates increase.

🔄 Debt Consolidation

Personal loans with lower rates can simplify payments and reduce interest, but avoid taking on new debt.

💡 Side Income

Even $100-200 extra monthly from freelancing, selling items, or gig work can cut years off payoff time.

Real-World Examples

Example 1: Multiple Credit Card Debt

Situation: John has three credit cards: $5,000 at 24%, $3,000 at 18%, and $2,000 at 15%. He can pay $500 total monthly.
Using the calculator: Avalanche method: Pay minimums + extra to 24% card first. Payoff time: 22 months, Total interest: $1,847
Result interpretation: By focusing extra payments on the highest interest card first, John saves $432 compared to paying equally across all cards.

Frequently Asked Questions

Should I use the debt avalanche or snowball method?

Debt avalanche (paying highest interest first) saves more money mathematically. Debt snowball (smallest balance first) provides psychological wins that help maintain motivation. Choose based on your personality and motivation style.

How much extra should I pay toward debt?

Pay as much extra as possible while maintaining a small emergency fund ($1,000-$2,500) and meeting basic needs. Even an extra $50-100 monthly can significantly reduce payoff time and interest costs.

Should I pay off debt or invest?

Generally, pay off high-interest debt (>7-8%) before investing, especially credit cards. For lower-interest debt like mortgages, investing might provide better returns. Consider your risk tolerance and overall financial situation.
