Tips: Enter the principal amount in USD, annual interest rate as a percentage, and loan term in years. All values must be positive numbers.
Q1: What is included in the monthly payment?
A: This calculation includes principal and interest only. Additional costs like property taxes, insurance, and PMI are not included.
