PITI Mortgage Calculator

Enter your monthly principal and interest payment from your lender, your annual property tax, and your annual insurance to calculate your total monthly PITI payment. Add your expected rent to see how PITI compares as a percentage of rental income.


How to use this tool

Get your monthly principal and interest (P+I) figure from your lender quote or a mortgage calculator. Enter your annual property tax and annual insurance separately. If you have an escrow account, your lender will have these figures. The optional rent field calculates PITI as a percentage of income.

Understanding your results

Monthly PITI is the full monthly cost of holding the property: principal, interest, property tax (monthly), and insurance (monthly). Lenders use PITI to assess affordability. PITI as % of rent shows how much of your rental income the mortgage consumes. A ratio below 80% leaves room for other expenses and vacancy.

Legal context

Lenders use PITI to calculate your debt-to-income ratio (DTI). For investment properties, Fannie Mae and Freddie Mac typically require a Debt Service Coverage Ratio (DSCR) of 1.25 or higher, meaning rental income must be at least 125% of PITI. Property tax rates vary by state and county. HOA fees are not included in PITI but are counted in lender DTI calculations.

Frequently asked questions

What does PITI stand for?

PITI stands for Principal, Interest, Taxes, and Insurance. It represents the four components of a standard monthly mortgage payment. Principal is the loan repayment. Interest is the cost of borrowing. Taxes refers to property tax, and Insurance refers to homeowners insurance. Together they make up the total monthly housing cost used by lenders to assess affordability.

What DSCR do lenders require for investment properties?

Most conventional lenders require a Debt Service Coverage Ratio (DSCR) of 1.25 for investment properties, meaning rental income must be at least 125% of the monthly debt service (PITI). Some DSCR loan products accept ratios as low as 1.0, while more conservative lenders require 1.30 or above. A higher DSCR makes approval more likely and may secure better loan terms.

What are typical property tax rates in California?

California property tax rates are capped at 1% of assessed value under Proposition 13, plus local levies that typically add 0.2%–0.5%. Total effective rates are usually 1.1%–1.3%. Assessed value is set at purchase price and can only increase by up to 2% per year until the property is sold. This makes California taxes predictable for long-term holders but can mean significant jumps after a sale.

What are typical property tax rates in Texas?

Texas has no state income tax but funds local services largely through property taxes. Effective rates typically range from 1.6% to 2.5% of assessed value, making Texas one of the highest property tax states in the country. In Dallas-Fort Worth and Houston metro areas, rates of 2.0%–2.3% are common. Tax bills are based on annually appraised market value.

What are typical property tax rates in New York?

New York State property tax rates vary widely. New York City applies complex assessment rules that often result in lower effective rates for residential properties. Outside the city, suburban counties in Westchester, Nassau, and Suffolk can have effective rates of 2.0%–3.0%, among the highest in the country. Upstate New York also tends to have high rates due to local school district funding requirements.

What are typical property tax rates in Florida?

Florida effective property tax rates typically range from 0.8% to 1.2% of assessed value, below the national average. Rates vary by county: Miami-Dade, Broward, and Palm Beach counties tend to have rates around 1.0%–1.1%. Florida offers a Homestead Exemption for primary residences but investment properties do not qualify. Assessment increases are capped at 10% per year for non-homestead properties.

Does PITI include HOA fees?

No. HOA fees are not part of PITI but lenders do include them when calculating your debt-to-income ratio. If your property has an HOA, add the monthly fee to your PITI when assessing affordability and cash flow. Some DSCR loan calculations also deduct HOA fees from rental income before calculating coverage.

What is a PITI-to-rent ratio?

PITI-to-rent ratio measures what percentage of your gross monthly rent the PITI payment consumes. A ratio of 75% means $750 of every $1,000 in rent goes to PITI, leaving $250 for other expenses. Most investors target a PITI-to-rent ratio below 80% to maintain positive cash flow after factoring in vacancy, maintenance, and management costs.

How do I reduce my monthly PITI?

PITI can be reduced by making a larger down payment (reduces principal and interest), shopping for a lower interest rate, appealing your property tax assessment, or comparing insurance providers for a lower premium. Refinancing at a lower rate when market rates fall also reduces the P+I component. You cannot reduce property tax by negotiating with your lender.

Is mortgage interest tax deductible for rental properties?

Yes. For rental properties, mortgage interest is fully deductible as a business expense on Schedule E. This applies to the interest portion of your monthly payment, not the principal. Property tax on rental properties is also deductible. These deductions reduce your taxable rental income and are separate from the mortgage interest deduction rules that apply to primary residences under the Tax Cuts and Jobs Act.
