How Mortgage Payments Work

A mortgage payment typically consists of four components, commonly referred to as PITI:

Principal: The amount that reduces your loan balance
Interest: The cost of borrowing, calculated on the remaining balance
Taxes: Property taxes (often held in escrow)
Insurance: Homeowners insurance and possibly PMI

Understanding Your Amortization Schedule

In the early years of a mortgage, most of your payment goes toward interest. As the balance decreases, more of each payment applies to principal. This is why making extra payments early can save substantial interest.

Factors That Affect Your Payment

Factor	Impact
Interest Rate	Higher rates increase monthly payment significantly
Loan Term	Longer terms lower monthly payment but increase total interest
Down Payment	Larger down payments reduce loan amount and may avoid PMI
Property Taxes	Vary by location, added to monthly payment
Insurance	Required by lenders, varies by property value

Tips to Lower Your Payment

Increase your down payment to avoid PMI (typically need 20%+)
Shop for lower rates — even 0.25% saves thousands over 30 years
Consider a longer term if cash flow is tight (but watch total interest)
Improve your credit score to qualify for better rates

Common Questions

Should I include taxes and insurance?

Yes — most lenders require escrow for taxes and insurance, so your actual monthly obligation includes these. Our calculator shows both the P&I payment and the full PITI.

What is PMI?

Private Mortgage Insurance protects the lender if you default. It's typically required when your down payment is less than 20% of the home price.

Frequently Asked Questions

Your monthly payment uses the standard amortization formula: M = P[r(1+r)^n]/[(1+r)^n-1], where P is your loan amount, r is your monthly interest rate, and n is the total number of payments. Taxes, insurance, and PMI are added on top.

Yes. Most lenders require you to pay property taxes and homeowners insurance through escrow, so your "total monthly payment" (PITI) includes these. We provide both the principal & interest and the full PITI breakdown.

Private Mortgage Insurance (PMI) is required when your down payment is less than 20% of the home price. It protects the lender if you default. It typically drops off once you reach 20% equity.

A 20% down payment avoids PMI and reduces your monthly payment. However, many loans allow as little as 3-5% down. Use our Affordability Calculator to see what works for your situation.
