1. What is a Mortgage Calculator with Credit Karma Accuracy?

Definition: This calculator estimates monthly mortgage payments using the same accurate formula as Credit Karma's mortgage calculator.

Purpose: It helps homebuyers and homeowners understand their potential mortgage payments before applying for a loan.
