To calculate your mortgage payment, add:
Principal + Interest + Property Taxes + Insurance (+ Mortgage Insurance if required)
This is called PITI.
Principal & Interest: Based on loan amount, rate, and term Taxes: Annual property taxes ÷ 12 Insurance: Annual homeowners insurance ÷ 12 Mortgage Insurance: Applies to some loans The easiest way to calculate your mortgage payment instantly is using a tool:

What Makes Up a Mortgage Payment? (PITI Explained) 1. Principal The amount you borrowed that you repay over time.
2. Interest The cost of borrowing money, based on your interest rate.
3. Property Taxes Typically paid annually but divided into monthly payments via escrow.
4. Homeowners Insurance Protects your home and is usually included in your monthly payment.
5. Mortgage Insurance (If Applicable) PMI for conventional loans (low down payment) MIP for FHA loans Step-by-Step: How to Calculate Your Mortgage Payment Let’s walk through a realistic example.
Example Scenario (Illustrative Only) Home price: $400,000 Down payment: $80,000 Loan amount: $320,000 Loan term: 30 years Property taxes: $4,800/year Insurance: $1,200/year Step 1: Calculate Principal & Interest This depends on:
Loan amount Interest rate Loan term With a fixed-rate loan, this portion stays consistent.
Step 2: Add Property Taxes $4,800 ÷ 12 = $400/month
Step 3: Add Homeowners Insurance $1,200 ÷ 12 = $100/month
Step 4: Add Mortgage Insurance (If Required) Typically:
$100–$200/month (varies by loan & down payment) Step 5: Total Monthly Payment Component Monthly Estimate Principal & Interest $X,XXX Property Taxes $400 Insurance $100 Mortgage Insurance $150 Total Payment $X,XXX

What Affects Your Mortgage Payment the Most? 1. Loan Type Fixed vs adjustable rate FHA, VA, Conventional, Jumbo 2. Down Payment Higher down payment → lower monthly payment Lower down payment → may add mortgage insurance 3. Loan Term Term
Monthly Payment

4. Location Property taxes vary by county/state Insurance varies by region (flood, fire, etc.) What Is Escrow (And Why It Matters)? Most lenders include an escrow account:
You pay taxes & insurance monthly Lender pays them on your behalf This keeps your payment predictable instead of large yearly bills.
How Accurate Are Mortgage Calculators? Mortgage calculators are excellent for planning, but:
They use estimated taxes & insurance They don’t include lender-specific pricing They may not reflect your exact credit profile For exact numbers, you’ll need a Loan Estimate from a lender
From Estimating Payments → Choosing the Right Loan At this point, you understand how payments are calculated.
But here’s what most buyers realize next:
The same home price can produce very different payments depending on the lender, loan structure, and pricing.
That’s where comparing options becomes critical.
