## Overview

A $400,000 loan at 6% over 30 years comes to about $2,398 a month before taxes and insurance. Lenders often pair a payment like this with a household income in the high-$80,000s, since principal and interest alone eat a big slice of take-home pay. Across the full term the interest totals roughly $463,400, lifting everything you repay to about $863,400.

## Method

The principal-and-interest portion is computed using the standard level-payment amortization formula: M = P × r(1+r)ⁿ / ((1+r)ⁿ − 1), where P is the loan amount (home price minus down payment), r is the monthly interest rate (annual rate divided by 12), and n is the total number of monthly payments (term in years multiplied by 12). At a 0% rate the formula simplifies to M = P / n. From that fixed P&I payment, a month-by-month amortization schedule is built: each month's interest equals the remaining balance multiplied by the monthly rate, the remainder of the payment reduces the principal, and the final month absorbs any accumulated rounding difference so the balance closes exactly to zero. Property tax and home insurance are divided by 12 and added to P&I each month; PMI and HOA dues are added as their stated monthly amounts. Summing these components produces the PITI total shown in the headline.
