A mortgage payment calculator is the most important tool a home buyer can use before signing anything. Your monthly mortgage payment isn’t just principal and interest — it includes property taxes, homeowners insurance, PMI if your down payment is under 20%, and HOA fees if applicable. This free mortgage calculator breaks down every component of your payment, shows you the full 30-year amortization schedule, calculates exactly how much extra payments save, and lets you compare a 15-year vs 30-year loan side-by-side. Whether you’re a first-time buyer in California, a refinancing homeowner in Texas, or a mortgage broker in Florida running scenarios for a client, this tool gives you the numbers you need.

What Is Included in a Monthly Mortgage Payment?

Most people think their mortgage payment is just the amount they borrowed divided by the number of months. In reality, a full mortgage payment — what lenders call PITI — includes four distinct components, and sometimes two more:

🏦

Principal (P)

The portion of your payment that reduces your actual loan balance. In early years, this is a small fraction of your total payment — most of it goes to interest.

💰

Interest (I)

The lender’s fee for lending you money. Calculated as your outstanding balance × monthly rate. The largest component early in the loan, shrinking over time.

🏛️

Taxes (T)

Monthly property tax escrow collected by your lender and paid to your county. Typically 1–2% of home value annually, divided by 12 for monthly payments.

🛡️

Insurance (I)

Homeowners insurance escrowed monthly. Also includes PMI (Private Mortgage Insurance) if your down payment was under 20%, and HOA fees if applicable.

Real Example: A $400,000 home with 20% down at 6.5% for 30 years has a P&I payment of $2,023/month. Add $333/month taxes, $125/month insurance, and $0 PMI (20% down) = $2,481 total monthly payment. This calculator computes all of this automatically — just enter your numbers.

How the Mortgage Payment Formula Works

Mortgage payments use the standard amortization formula that keeps your payment constant while gradually shifting the split between interest and principal:

Monthly Payment Formula (P&I Only)
M = P × [r(1+r)ⁿ] ÷ [(1+r)ⁿ − 1]
P = Loan amount | r = Monthly rate (annual ÷ 12) | n = Total payments
Example: $320,000 loan at 6.5% for 30 years → r = 0.005417, n = 360 → M = $2,023/month

How to Use This Mortgage Calculator

1

Enter Home Price and Down Payment

Enter your target home price and the percentage you plan to put down. The calculator computes your loan amount automatically. If your down payment is under 20%, consider adding monthly PMI.

2

Set Loan Term and Interest Rate

Choose 15, 20, or 30 years. Enter your expected rate (check current rates from your lender or use the national average). Use the 15 vs 30 Year Compare button to see the cost difference instantly.

3

Add Property Taxes, Insurance, PMI & HOA

These are real costs that your lender will collect monthly. Annual property tax is typically 1–2% of home value. Insurance averages $1,200–$2,000/year. PMI is usually 0.5–1.5% of loan amount annually.

4

Test Extra Monthly Payments

See how much interest you can save by paying extra each month. Even $100–$200 extra per month can shave years off your mortgage and save tens of thousands in interest.

15-Year vs 30-Year Mortgage: Which Is Right for You?

This is the single most impactful decision in mortgage selection. Here’s a clear comparison:

Interest RateTypically 0.5–0.75% lowerStandard rate
Equity Building SpeedVery fastSlow in early years
Cash Flow FlexibilityLess flexibleMore flexible

The Real Cost Difference: On a $320,000 loan at 6.5% — a 15-year mortgage costs about $2,790/month but only $182,000 in total interest. The 30-year costs $2,023/month but $408,000 in total interest — over $226,000 more. Use the “15 vs 30 yr” compare button to see this for your exact numbers.

How Extra Mortgage Payments Save You Thousands

The interest savings from extra payments are dramatic and often underestimated. Here’s why: your outstanding balance is recalculated every month. Any extra payment goes directly to principal, which lowers every future interest charge for the rest of the loan.

  • $100 extra/month on a $320k 30-year loan at 6.5% saves approximately $30,000 and 2.5 years
  • $200 extra/month saves approximately $54,000 and 4.5 years
  • $500 extra/month saves approximately $110,000 and 9 years

Understanding PMI: When It Applies and When It Drops

Private Mortgage Insurance is required when your loan-to-value ratio exceeds 80% — meaning your down payment is less than 20%. PMI typically costs 0.5–1.5% of your loan amount annually. On a $320,000 loan, that’s $133–$400/month added to your payment.

The good news: PMI is not permanent. Under federal law (Homeowners Protection Act), lenders must automatically cancel PMI when your loan balance drops to 78% of the original purchase price. You can also request removal at 80% LTV. This calculator automatically shows when PMI drops off based on your amortization schedule.

Frequently Asked Questions About Mortgage Payments

How is a monthly mortgage payment calculated?
A monthly mortgage payment uses the amortization formula M = P × [r(1+r)ⁿ] ÷ [(1+r)ⁿ − 1], where P is the loan amount, r is the monthly interest rate (annual ÷ 12), and n is the total number of payments. The full monthly cost also adds property tax, homeowners insurance, PMI if applicable, and HOA fees.
What is a good down payment for a house in the USA?
The traditional target is 20% to avoid Private Mortgage Insurance (PMI). However, FHA loans allow as little as 3.5% down, and some conventional loans allow 3–5%. A larger down payment reduces your monthly payment, eliminates PMI, and lowers total interest paid. This calculator shows exactly how your payment changes with different down payment amounts.
What is the difference between a 15-year and 30-year mortgage?
A 30-year mortgage has lower monthly payments but significantly higher total interest paid. A 15-year mortgage has higher monthly payments but typically a lower interest rate, and you pay roughly half the total interest. Use the 15 vs 30 Year comparison button in this calculator to see the exact dollar difference for your home price and rate.
What is PMI and when can I remove it?
Private Mortgage Insurance (PMI) is required when your down payment is less than 20%. It’s typically 0.5–1.5% of the loan annually. PMI must be automatically cancelled by federal law when your loan balance reaches 78% of the original value. You can request removal at 80% LTV. This calculator shows exactly when PMI drops off in your amortization schedule.
How much does an extra monthly payment save?
Extra payments go directly to principal, reducing every future interest charge. On a $320,000 30-year loan at 6.5%, an extra $200/month saves approximately $54,000 in interest and cuts 4.5 years off the loan. Enter your extra payment amount in the calculator above to see your personalized savings.
What is PITI in a mortgage?
PITI stands for Principal, Interest, Taxes, and Insurance — the four standard components of a full mortgage payment. Principal reduces your loan balance. Interest is the lender’s charge. Taxes are property taxes escrowed monthly. Insurance is homeowners insurance. Lenders often also include PMI and HOA fees in the monthly escrow payment.
What credit score gets the best mortgage rate?
Most lenders offer the best mortgage rates to borrowers with credit scores of 740 or above. Scores between 620–739 will qualify for conventional loans but at higher rates. FHA loans accept scores as low as 580. Even a 0.5% rate improvement saves significant money over 30 years — on a $320,000 loan, that’s roughly $32,000 in total interest savings.
What is the current mortgage rate in the USA (2026)?
As of April 2026, average 30-year fixed mortgage rates in the USA are approximately 6.5–7.5% for well-qualified borrowers. 15-year fixed rates are typically 0.5–0.75% lower. Rates vary based on credit score, loan type, down payment, lender, and Federal Reserve policy. Always compare multiple lenders for the best personalized rate.
How does an amortization schedule work?
An amortization schedule shows every monthly payment broken into principal and interest over the life of the loan. Early payments are mostly interest. Over time, the split shifts toward principal. By the final years, almost all of your payment reduces the balance. This calculator generates a full month-by-month table — click “View Full Amortization Schedule” to see it.
Does this calculator include taxes and insurance?
Yes. This calculator includes separate fields for annual property tax, annual homeowners insurance, monthly PMI, and monthly HOA fees. All are added to the principal and interest payment to show your true total monthly housing cost. The monthly breakdown chart shows exactly how much of your payment goes to each component.
