Mortgage Calculator With Taxes, Insurance, and PMI — Your Real Monthly Payment
That $1,500/month mortgage payment your calculator showed? Your real payment is probably $1,900–$2,200. Basic mortgage calculators only show principal and interest — they leave out property taxes, homeowner's insurance, and PMI. This guide explains every component of your true monthly payment and shows you how to calculate it accurately.

What PITI Means — The Full Payment
PITI stands for the four components of a complete mortgage payment:
- P — Principal: The portion paying down your loan balance
- I — Interest: The lender's fee for lending you money
- T — Taxes: Property taxes collected in escrow monthly
- I — Insurance: Homeowner's insurance + PMI if applicable
Most online calculators only show P+I. Your actual payment to the lender is PITI — and it can be 25%–50% higher than P+I alone.
Principal and Interest — The Calculator Part
P&I is calculated using this formula: M = P[r(1+r)^n]/[(1+r)^n-1] where M = monthly payment, P = loan amount, r = monthly interest rate, n = number of payments.
Real examples at 6.5% on 30-year fixed:
- $150,000 loan → $948/month P&I
- $200,000 loan → $1,264/month P&I
- $250,000 loan → $1,580/month P&I
- $300,000 loan → $1,896/month P&I
- $350,000 loan → $2,213/month P&I
- $400,000 loan → $2,528/month P&I
Use our mortgage calculator to get exact P&I for any loan amount and rate.
Property Taxes — The Biggest Variable
Property taxes are calculated annually as a percentage of assessed home value and divided into 12 monthly escrow payments. The US average is about 1.07% per year, but it varies enormously by state:
| State | Avg Rate | Monthly tax on $250k home |
|---|---|---|
| New Jersey | 2.23% | $465/month |
| Illinois | 2.08% | $433/month |
| Texas | 1.69% | $352/month |
| Florida | 0.98% | $204/month |
| Colorado | 0.60% | $125/month |
| Hawaii | 0.29% | $60/month |
Always use your specific county's tax rate — not national averages — for accurate calculations.
Homeowner's Insurance — Required by All Lenders
Lenders require homeowner's insurance as a condition of the mortgage. The national average is $1,428/year ($119/month) but varies significantly by location, home age, and coverage amount.
Factors that increase insurance cost:
- Coastal locations (hurricane/flood risk): +50%–200%
- Older homes (pre-1980): +20%–50%
- High-value homes: proportionally higher
- Poor credit score: +10%–30% in most states
- Wildfire zones (CA, CO, OR): dramatic increases
Budget $100–$200/month for most conventional homes. Get actual quotes before closing — insurance costs have risen 20%–30% in many markets since 2022.
PMI — Private Mortgage Insurance
PMI is required on conventional loans when your down payment is less than 20%. It protects the lender (not you) if you default. PMI costs typically 0.5%–1.5% of the loan amount annually.
PMI on a $250,000 loan:
- 0.5% rate → $104/month
- 1.0% rate → $208/month
- 1.5% rate → $313/month
Your PMI rate depends on credit score, loan-to-value ratio, and loan type. A 760+ credit score with 10% down gets the lowest PMI rate. Good news: PMI automatically cancels when your loan reaches 80% of original value, and you can request removal at 80% LTV.
FHA loans have MIP (mortgage insurance premium) instead of PMI — it works differently and often costs more long-term.
Full PITI Payment Examples
Here are complete payment breakdowns showing the difference between what basic calculators show and reality:
| Home Price | P&I only | +Taxes | +Insurance | +PMI | Real PITI |
|---|---|---|---|---|---|
| $200,000 | $1,138 | +$175 | +$110 | +$140 | $1,563 |
| $300,000 | $1,707 | +$260 | +$140 | +$200 | $2,307 |
| $400,000 | $2,276 | +$350 | +$170 | +$250 | $3,046 |
Assumptions: 6.5% rate, 30-year, 10% down, 1.05% avg tax rate, standard insurance, 1.0% PMI. Your numbers will differ based on location and credit.

How to Calculate PITI Manually
Step-by-step PITI calculation for a $300,000 home, 10% down, 6.5% rate, Texas location:
- Loan amount: $300,000 − $30,000 down = $270,000
- P&I: $270,000 at 6.5% for 360 months = $1,707/month
- Annual property tax: $300,000 × 1.69% (TX avg) = $5,070 ÷ 12 = $423/month
- Homeowner's insurance: $1,500/year ÷ 12 = $125/month
- PMI: $270,000 × 0.80% ÷ 12 = $180/month
- Total PITI: $1,707 + $423 + $125 + $180 = $2,435/month
That is $728/month — or 43% — more than the P&I-only figure. Always calculate PITI before deciding on a home price.
Pros and Cons
Pros
- ✅ Understanding PITI prevents budget shock after moving in
- ✅ Escrowing taxes and insurance makes payment predictable
- ✅ PMI is temporary — removed at 20% equity (conventional loans)
- ✅ Higher down payment eliminates PMI and reduces total PITI
- ✅ Shopping states with low property tax rates dramatically reduces PITI
Watch Out
- ❌ Basic calculators hide 25%–50% of actual monthly payment
- ❌ Property taxes can increase annually — PITI is not fixed
- ❌ Insurance costs have risen 20%–30% since 2022 in many markets
- ❌ FHA MIP lasts the life of the loan (if less than 10% down)
- ❌ PMI provides zero benefit to the borrower — it protects the lender
Frequently Asked Questions
PITI stands for Principal, Interest, Taxes, and Insurance — the four components of a complete monthly mortgage payment. Principal reduces your loan balance, interest is the lender's fee, taxes are property taxes collected in escrow, and insurance covers homeowner's insurance plus PMI if your down payment was less than 20%.
PMI typically adds 0.5%–1.5% of the loan amount per year, divided into monthly payments. On a $250,000 loan, PMI adds $104–$313/month depending on your credit score and loan-to-value ratio. PMI is required on conventional loans with less than 20% down and automatically cancels when your loan balance reaches 80% of the original home value.
Most basic mortgage calculators only show principal and interest (P&I). Our mortgage calculator includes property taxes, homeowner's insurance, and PMI for a complete PITI payment estimate. Always use a PITI calculator — not just P&I — when budgeting for a home purchase.
Annual property tax ÷ 12 = monthly tax payment. To find your annual tax: home value × local tax rate. Example: $300,000 home in Texas (1.69% rate) = $5,070/year ÷ 12 = $423/month. Find your county's exact tax rate at the county assessor's website for the most accurate estimate.
On conventional loans, PMI automatically cancels when your mortgage balance reaches 78% of the original purchase price (by law under the Homeowners Protection Act). You can request removal at 80% LTV. FHA MIP works differently — if your down payment was less than 10%, MIP lasts the entire loan term. With 10%+ down on FHA, MIP drops after 11 years.
