How Mortgage Payments Are Calculated

Your monthly mortgage payment is calculated using this standard formula that takes into account your loan amount, interest rate, and how long you'll take to pay it back. The formula ensures your payment stays the same every month while the mix of principal and interest changes over time.

M = P \times \frac{r(1+r)^n}{(1+r)^n - 1}

Variables Explained:

M
Your monthly mortgage payment
P
The principal amount you're borrowing
r
Your monthly interest rate (yearly rate divided by 12)
n
Total number of monthly payments (years times 12)

Why Use Our Advanced Mortgage Calculator?

The detailed amortization schedule shows you exactly how much principal and interest you'll pay each year, helping you understand how your loan balance decreases over time. This transparency empowers you to make informed decisions about down payment amounts, loan terms, and whether refinancing makes sense in the future.
