Calculation Overview
Find your fastest path to becoming debt-free. Calculate payoff timelines and total interest costs.
Mathematical Model & Formula
n = -log(1 - (B*r)/PMT) / log(1 + r)
Uses logarithmic debt formulas to compute the precise number of compounding months required to clear the balance.
Variables Defined:
- B: Starting debt balance
- r: Monthly interest rate
- PMT: Monthly payment amount
Worked Example Scenario
Scenario: Paying off $15,000 at 18% with $500/mo.
- r = 0.18 / 12 = 0.015
- Monthly interest = $225
- Deducts principal recursive progress.
Result: Clears in 42 months.
Frequently Asked Questions
How can I lower my debt payoff timeline?
The single most effective action is paying more than the minimum payments, as every extra dollar reduces the principal balance directly.
