1. What is the Monthly Payment Calculator?

The Monthly Payment Calculator determines the fixed monthly payment required to pay off a loan over a specified term using the standard amortization formula. It helps borrowers understand their payment obligations for mortgages, car loans, and other installment loans.

2. How Does the Calculator Work?

The calculator uses the amortization formula:

\[ Monthly\ Payment = \frac{P \times r \times (1 + r)^n}{(1 + r)^n - 1} \]
