Accelerate Loan Repayment
Making extra principal payments reduces your loan balance faster, shortening the term and cutting total interest. Even small extra payments have a compounding benefit over the life of the loan.
What is the Repayment Calculator?
The Repayment Calculator is a specialized tool that helps borrowers answer one question: "If I want to pay off this debt in exactly X months, how much do I need to pay each month?"
How It Works (Formula)
Instead of solving for the length of time (like a credit card calculator), this tool solves for the payment amount. It uses an inverted annuity formula, forcing the amortization schedule to zero out precisely on your target date.
$$ PMT = \frac{P \times r}{1 - (1+r)^{-n}} $$
The amortized payment algorithm driven by a fixed time constraint ($n$).
How to Use It
Enter your total debt balance and the interest rate. Then, input your aggressive goal (e.g., "I want this paid off in 18 months"). The calculator will output the exact monthly payment required to achieve that goal.
