Mortgage Property Tax Calculator: How to Estimate PITI by State
Searchers often look for a mortgage property tax calculator, a property tax loan calculator, or a mortgage calculator with taxes and insurance — all asking the same question: what is the full monthly payment once local taxes and insurance are included?
The Mortgage Calculator answers that by combining:
- Principal and interest from the standard amortization formula
- Property tax escrow using state-level effective rates (county overrides where configured)
- Homeowners insurance using statewide planning estimates
- private mortgage insurance (PMI) when your down payment is below 20%
For a deeper split of each component, use the PITI Breakdown Calculator after you run the state mortgage calculator.
PITI by State: $300,000 Home, 20% Down, 6.5% Rate
| State | Principal & Interest | Property Tax (est.) | Insurance (est.) | Total PITI |
|---|---|---|---|---|
| Hawaii | $1,517 | $42 | $122 | $1,681 |
| Colorado | $1,517 | $105 | $165 | $1,787 |
| California | $1,517 | $185 | $139 | $1,841 |
| Florida | $1,517 | $264 | $212 | $1,993 |
| Illinois | $1,517 | $555 | $142 | $2,214 |
| Texas | $1,517 | $565 | $248 | $2,330 |
| New Jersey | $1,517 | $608 | $129 | $2,254 |
| New Hampshire | $1,517 | $458 | $131 | $2,106 |
| Vermont | $1,517 | $441 | $145 | $2,103 |
| Rhode Island | $1,517 | $449 | $152 | $2,118 |
*Property tax estimated using effective rates on $300,000 market value. Insurance is median statewide for $300k dwelling. P&I (principal and interest) amortized at 6.5% on $240,000 loan.
The principal and interest portion is the same across all states ($1,517) because the loan amount and rate are identical. The entire difference comes from two components:
- T — Property tax: Ranges from $42/month (HI) to $608/month (NJ)
- I — Insurance: Ranges from $122/month (HI) to $248/month (TX)
PITI vs. DTI: How Lenders Qualify You
Lenders use the 28/36 DTI (debt-to-income) rule to determine your maximum loan:
- 28% rule: PITI should not exceed 28% of your gross monthly income
- 36% rule: Total debt (PITI + car loans + student loans + credit cards) should not exceed 36%
PITI is the key variable in the 28% front-end ratio. In a low-tax state like Hawaii, $1,681 PITI → requires $72,043/year minimum income for the 28% rule to work. In New Jersey, $2,311 PITI → requires $99,043/year.
| State | PITI | Min income (28%) | Max loan (66k income) |
|---|---|---|---|
| Hawaii | $1,681 | $72,043 | $235,000 |
| Colorado | $1,787 | $76,586 | $222,000 |
| Florida | $1,993 | $85,414 | $196,000 |
| Texas | $2,330 | $99,857 | $156,000 |
| New Jersey | $2,254 | $96,600 | $162,000 |
*Max loan assumes $66k annual income (national median), 6.5% rate, 20% down, state-specific PITI.
The same income gets you $79,000 more home in Hawaii than in New Jersey — solely because of property tax differences.
Three Components That Change (and Two That Don’t)
Fixed for life of loan
- Principal & Interest — On a 30-year fixed $240,000 loan at 6.5%, P&I stays $1,517/month for 360 months
Change over time
- Property taxes — Increase with property reassessments and local tax rate changes
- Homeowners insurance — Increases with inflation, claim frequency, and property value changes
- Escrow adjustments — Lenders re-evaluate escrow annually; payments adjust up or down based on actual tax/insurance costs
Calculator Methodology
PITI is calculated as:
- Principal & Interest: $240,000 loan at 6.5%, 30-year fixed amortization
- Taxes: Effective property tax rate * $300,000 / 12 (rates sourced from Tax Foundation 2024 data)
- Insurance: Median annual premium for $300,000 dwelling / 12
Standard amortization formula:
Payment = P * r(1 + r)^n / ((1 + r)^n - 1)Where P = $240,000, r = 0.0054167 (6.5%/12), n = 360 months.

Frequently Asked Questions
What does PITI stand for in a mortgage payment?
PITI stands for Principal, Interest, Taxes, and Insurance. Principal and interest repay your loan. Taxes go to your local government based on your home's assessed value and the local property tax rate. Insurance covers hazard/homeowners insurance. Together, PITI makes up your full monthly housing payment.
How much of my monthly payment goes to property tax?
It depends entirely on your state and local tax rate. In New Jersey, property taxes on a $300,000 home are roughly $600/month (2.43% effective rate). In Hawaii, they are about $42/month (0.17% effective rate). The average across the U.S. is roughly $250-$350/month on a $300,000 home.
How does PITI affect how much house I can afford?
Lenders use the 28/36 DTI (debt-to-income) rule: your PITI should not exceed 28% of gross monthly income, and total debt payments should not exceed 36%. In high-tax states, the T (taxes) portion eats more of that 28% budget, reducing your maximum loan amount. Use a mortgage calculator with state tax data for an accurate estimate.
Is homeowners insurance included in PITI?
Yes. Lenders require homeowners insurance and typically collect the premium through your monthly payment into an escrow account. The annual premium is divided by 12 and added to your PITI. Average insurance runs $100-$200/month depending on your state, home value, and coverage level.
Does PITI change over time?
Yes. The P and I (principal and interest) are fixed on a 30-year fixed-rate loan. The T (taxes) and I (insurance) typically increase each year. Property taxes rise with reassessments and millage rate changes. Homeowners insurance premiums increase with inflation and claim trends. Your monthly payment will gradually rise even if your rate and term stay the same.
Which state has the highest PITI on a $300k home?
New Jersey has the highest PITI at roughly $2,311/month on a $300,000 home with 20% down at 6.5% — driven by the nation's highest effective property tax rate (2.43%). Texas is close at $2,163/month due to high taxes (1.6%) and higher insurance costs from weather risk.
PITI vs. DTI: What is the difference between these two mortgage ratios?
PITI (principal, interest, taxes, insurance) is your total monthly housing payment. DTI (debt-to-income) is the ratio lenders use to qualify you — your PITI plus other debts divided by your gross monthly income. PITI is part of DTI. The 28/36 rule means PITI should not exceed 28% of income (front-end), and total debt including PITI should not exceed 36% (back-end).
