Mortgage Glossary

Amortization

The process of paying off debt over time through regular payments of principal and interest.

Principal

The original amount of money borrowed, excluding any interest or fees.

PMI

Private Mortgage Insurance, usually required if your down payment is less than 20%.

How it calculates

M = P [ r(1 + r)^n ] / [ (1 + r)^n - 1]

M = Monthly payment | P = Principal loan amount | r = Monthly interest rate | n = Number of months

Frequently Asked Questions

Common questions about the Mortgage Calculator.

Should I choose a fixed or variable rate?

Fixed rates offer stability as your payment never changes, while variable rates (ARMs) often start lower but can increase over time. Choose fixed if you value predictability.

What is an amortization schedule?

It is a table showing every monthly payment over the life of the loan. It breaks down how much of each payment goes toward the interest versus the loan balance (principal).
