Calculate how long it will take to pay off your debt and how much interest you'll pay
What is a Debt Payoff Goal Calculator?
A Debt Payoff Goal Calculator is a financial tool that helps individuals or businesses determine how long it will take to pay off their debt based on:
Current debt balance
Monthly payment amount
Interest rate
Desired payoff timeline
It provides a structured plan to eliminate debt efficiently, whether using methods like the Debt Snowball (paying smallest debts first) or Debt Avalanche (paying highest-interest debts first).
