A Python-based debt payoff calculator that helps you strategically plan your debt repayment. This tool compares two popular debt repayment strategies:

• Debt Avalanche: Pay off debts with the highest interest rate first (saves more money)
• Debt Snowball: Pay off debts with the lowest balance first (provides quick wins)

• Calculate payoff time for multiple debts
• Compare Avalanche vs Snowball strategies
• Track total interest paid
• Visualize debt payoff timeline
• Get personalized recommendations
