Mortgage Payments Calculator: Estimate Your Monthly Housing Costs

What Is a Mortgage Payment?
A mortgage payment is a regularly scheduled payment made by a borrower to a lender. It typically consists of several components:
- Principal: The amount borrowed to buy the home
- Interest: The lender’s charge for loaning you the money
- Property Taxes: Annual taxes paid to local government, often divided monthly
- Homeowners Insurance: Required to protect the home and lender
- PMI (Private Mortgage Insurance): Applicable if your down payment is less than 20%
Why Use a Mortgage Payments Calculator?
Knowing your monthly payment amount before taking out a loan helps you:
- Determine affordability and budget accurately
- Compare loan options (15-year vs. 30-year, fixed vs. adjustable)
- Plan for additional costs like taxes and insurance
- Evaluate how much you can borrow responsibly

How Is Mortgage Payment Calculated?
The formula used is:
M = P × [r(1 + r)n] ÷ [(1 + r)n – 1]

- P: Loan amount (home price – down payment)
- r: Monthly interest rate (annual rate ÷ 12)
- n: Number of monthly payments (loan term × 12)

Frequently Asked Questions
1. How much mortgage can I afford?
Use the 28/36 rule: spend no more than 28% of your gross income on housing and 36% on total debt.
2. Can I reduce my monthly mortgage payment?
Yes, by making a larger down payment, choosing a longer loan term, refinancing at a lower interest rate, or eliminating PMI.
3. How do extra payments affect the mortgage?
Extra payments toward principal reduce your loan balance faster and save on interest over time.
4. Are taxes and insurance included in the monthly payment?
Yes, if you choose escrow, your lender collects a portion of these costs monthly along with principal and interest.
5. What is PMI and when is it required?
Private Mortgage Insurance is required if your down payment is less than 20%. It protects the lender in case of default.
