Frequently Asked Questions

How is a monthly mortgage payment calculated?

Monthly mortgage payments are calculated using the standard amortization formula: M = P * [r(1+r)^n] / [(1+r)^n - 1], where M is monthly payment, P is principal, r is monthly interest rate, and n is total payments.

What does PITI stand for in a mortgage?

PITI stands for Principal, Interest, Taxes, and Insurance. These are the four core components of a monthly mortgage payment.

How does a larger down payment affect my mortgage?

A larger down payment reduces the principal loan amount you need to borrow. This directly lowers your monthly payment, reduces total interest paid, and can eliminate Private Mortgage Insurance (PMI) if you reach 20% down.
