Loan Balance Over Time

Understanding Your Mortgage Payment

Your total monthly payment has two parts: Principal & Interest (P&I) — the principal pays down your loan balance while interest is the cost of borrowing — plus Taxes & Insurance, which most lenders collect monthly and hold in escrow to pay your property tax and homeowners insurance bills when they come due. If you put less than 20% down, private mortgage insurance (PMI) is also added.

The 28/36 Rule

A common guideline: your total housing payment should stay under 28% of gross monthly income, and total debt under 36%.

Extra Payments Matter

Adding even one extra payment per year can shave years off a 30-year mortgage and save tens of thousands in interest.
