Advanced Debt Payoff Calculator

Manage and optimize multiple debts with advanced strategies, balance transfers, and consolidation options. Analyze total interest, payoff time, and repayment efficiency to make smarter financial decisions.

How It Works

  • - Each debt accrues interest monthly based on APR
  • - Payments are applied toward interest first, then principal
  • - Multiple debts are handled simultaneously
  • - Extra payments accelerate payoff and reduce interest

Core Formulas

  • - Monthly Interest = Balance × (APR / 12)
  • - Principal Paid = Payment - Interest
  • - Remaining Balance = Balance - Principal Paid
  • - Total Interest = Sum of all interest payments

Repayment Strategies

  • - Minimum: Pay required minimum (slowest, highest cost)
  • - Fixed: Consistent monthly payment
  • - Snowball: Pay smallest balance first
  • - Avalanche: Pay highest interest first
  • - Custom: User-defined priority order

Balance Transfer

  • - Promotional APR temporarily reduces interest
  • - Transfer fee increases total balance
  • - After promo period → normal interest applies
  • - Best used for short-term aggressive payoff

Loan Consolidation

  • - Combines all debts into one fixed loan
  • - Monthly Payment (EMI) = P × r / (1 - (1+r)^-n)
  • - Lower interest loan → potential savings
  • - Longer terms → lower payments but higher total interest

Cost Breakdown

  • - Principal: Original borrowed amount
  • - Interest: Cost of borrowing over time
  • - Fees: Transfer + consolidation charges
  • - Total Cost = Principal + Interest + Fees

Smart Insights

  • - Avalanche method saves the most money
  • - Snowball improves motivation and consistency
  • - Extra payments reduce years of debt
  • - Always compare total interest, not monthly payment
  • - Avoid new debt during repayment period
