🟦 How Mortgage Payments Are Calculated in the USA
A standard mortgage payment includes four main components. These are known as PITI:
1. Principal
The part of your payment that reduces your loan amount.
2. Interest
The cost you pay to borrow the money, based on your interest rate.
3. Taxes
Property taxes vary by state and county.
Example: Texas has higher property taxes compared to California or New York.
4. Insurance
Homeowners insurance is required by most lenders.
Optional: HOA Fees
If you live in a community or condo, you may need to pay monthly HOA charges.

To help you understand, here’s an example calculation:
| Input | Value |
|---|---|
| Home Price | $400,000 |
| Down Payment | $80,000 |
| Loan Amount | $320,000 |
| Interest Rate | 6.50% |
| Loan Term | 30 years |
| Property Tax | $2,800 / year |
| Insurance | $1,200 / year |
| HOA | $0 |
Results
- Monthly PI (Principal + Interest): ~$2,023
- Property Tax + Insurance: ~$250
- Total Monthly Payment: ~$2,273
- Total Interest Over 30 Years: ~$409,000
This means you will pay more in interest than principal unless you choose a shorter term (like a 15-year mortgage).
🟦 Types of Mortgages in the USA
There are four main mortgage types borrowers use:

🟦 Tips to Lower Your Mortgage Payment
Here are some smart ways to reduce your monthly housing costs:
✔ Improve your credit score
Better credit = lower interest = lower monthly payment.
✔ Increase your down payment
More down payment = less loan amount.
✔ Shop multiple lenders
Rates can vary significantly between lenders.
✔ Choose a longer loan term
30-year mortgages have smaller monthly payments than 15-year loans.
