💡 Advanced Mortgage Calculator
Buying a home or securing a large mortgage is a major financial decision. This tool uses the standard fixed-rate amortization algorithm. By simply entering the home price, down payment, expected annual interest rate, and loan term, you can instantly estimate your fixed monthly payment.
📐 Amortization Formula
The core logic of this calculator is based on the standard financial formula: $$M = P \frac{r(1+r)^n}{(1+r)^n - 1}$$ where $M$ is the monthly payment, $P$ is the principal loan amount, $r$ is the monthly interest rate, and $n$ is the number of payments. Our built-in dynamic pie chart clearly illustrates the significant proportion of interest paid over the life of the loan, helping you plan better financial strategies.
