How to Use This Calculator
Adjust the loan amount, interest rate, and term to mirror a financing scenario; add optional extra principal or escrow-related costs to model real-world payments. Once you calculate, results appear instantly in the right-hand panel so you can compare principal/interest, escrow, total payment, and payoff horizon.
Methodology
The computation relies on standard fixed-rate amortization formulas, converts every periodic payment to the monthly equivalent, and rolls optional extras into the monthly total. When the extra principal input is used, it is applied each period before the next cycle begins to accelerate payoff and reduce interest.
