Accelerate Debt Payoff
Paying more than the minimum each month dramatically reduces your total interest cost and payoff time. Even an extra $50-100/month can save years and thousands of dollars in interest on high-rate debt.
What is the Debt Payoff Calculator?
The Debt Payoff Calculator is an algorithmic strategy tool. It models how fast you can become debt-free by utilizing the famous "Snowball" method (paying smallest balances first) versus the "Avalanche" method (paying highest interest rates first).
How It Works (Algorithm)
The calculator runs amortization loops across multiple debts simultaneously. When one debt reaches a zero balance, the algorithm takes the money you were paying on that debt and "rolls it over" into the payment for the next debt, rapidly accelerating the payoff timeline.
$$ \text{Next Payment} = \text{Standard Payment} + \text{Rollover Cash} $$
The compounding logic behind the Debt Snowball strategy.
How to Use It
List all of your debts (student loans, car loans, credit cards) with their balances and interest rates. Enter how much extra cash you can afford to pay each month. The tool will mathematically map your fastest route to being 100% debt-free.
