Mortgage Loan Calculator Including Taxes and Insurance Formula
Where: P = Principal Loan Amount, r = Monthly Interest Rate, n = Total Payments.
Formula Source: The standard fixed-rate mortgage amortization formula is universally accepted and is provided by high-authority financial sources such as CFPB (Consumer Financial Protection Bureau) and Investopedia’s Mortgage Calculations Guide.
Variables Explained
- Loan Amount: The principal amount borrowed to purchase the home.
- Annual Interest Rate: The nominal annual interest rate for the loan (in percent).
- Loan Term (Years): The duration of the loan, typically 15 or 30 years.
- Annual Property Taxes: The estimated yearly cost of property taxes (P). This is divided by 12 for the monthly escrow amount (T).
- Annual Home Insurance (HOI): The annual premium for homeowners insurance (I). This is also divided by 12.
- Annual PMI (Private Mortgage Insurance): Insurance required if the down payment is less than 20%. This is optional and is divided by 12.

What is PITI?
PITI stands for Principal, Interest, Taxes, and Insurance. It is the comprehensive measure of a homeowner’s total monthly cost associated with their mortgage. While the Principal and Interest (P&I) cover the repayment of the loan balance, the Taxes and Insurance (T&I) components cover escrow items managed by the lender.
Lenders often require borrowers to pay T&I into an escrow account monthly to ensure these obligations are met, thus protecting their collateral (the home). This calculator combines all four elements to give you a true, full picture of your housing expense, which is critical for pre-qualification and budgeting.
How to Calculate PITI (Example)
- Step 1: Calculate Monthly P&I Payment (M). Using a $250,000 loan, 6% annual rate, and 30-year term. $r = 0.06 / 12 = 0.005$, $n = 30 \times 12 = 360$. $M = 250,000 \times [0.005(1.005)^{360} / ((1.005)^{360} – 1)] = \$1,498.88$.
- Step 2: Calculate Monthly Taxes and Insurance. Assume Annual Taxes are $4,800$ and Annual HOI is $1,000$. Monthly T&I = $(\$4,800 + \$1,000) / 12 = \$483.33$.
- Step 3: Calculate Total PITI. Add the P&I and T&I components. PITI = $\$1,498.88 + \$483.33 = \$1,982.21$.
Frequently Asked Questions (FAQ)
- What is the difference between P&I and PITI? P&I (Principal and Interest) is the amount that goes directly toward paying off the loan balance and interest. PITI includes P&I plus the required monthly payments for Property Taxes and Homeowner’s Insurance (T&I), providing the total monthly housing cost.
- Is Private Mortgage Insurance (PMI) always required? No, PMI is typically only required if your down payment is less than 20% of the home’s purchase price. Once you reach 20% equity, you can usually request to have PMI canceled.
- What is the maximum loan term I can choose? While loan terms vary, the most common fixed-rate mortgages are 30 years and 15 years. This calculator allows you to enter any number of years for flexibility.
- How often do the Tax and Insurance portions of PITI change? The P&I portion remains fixed for a fixed-rate loan. However, the T&I portions held in escrow can change annually based on property reassessments (taxes) and changes in insurance premiums (HOI).
