Monthly Payment Details
What Is PITI?
PITI stands for:
- Principal – The portion of your payment that goes toward reducing the loan balance.
- Interest – The cost of borrowing money from the lender.
- Taxes – Property taxes, typically collected monthly and held in escrow.
- Insurance – Homeowner’s insurance protecting your property against damages and liabilities.
These four components make up your total monthly mortgage payment and are essential for accurate budget planning.
Why Use a PITI Mortgage Calculator?
Many homeowners underestimate the true cost of homeownership by looking only at the loan amount or interest rate. Your mortgage payment often includes taxes and insurance, which can significantly increase monthly costs.
Using this calculator, you can:
- Estimate total monthly payments accurately
- Plan your budget before buying
- Compare different loan terms and interest rates
- Decide on the appropriate down payment
- Assess affordability of potential homes
By factoring in all components of PITI, you get a realistic view of your monthly expenses.
How the PITI Mortgage Calculator Works
The calculator uses standard mortgage formulas to compute principal and interest based on the loan amount, interest rate, and loan term.
- Principal & Interest (PI): Calculated using the formula for a fixed-rate mortgage:
PI=1−(1+MonthlyInterest)−TotalPaymentsLoanAmount×MonthlyInterest
- Property Tax & Home Insurance: Annual amounts are divided by 12 to get monthly contributions.
- Total PITI Payment: The sum of PI, monthly property tax, and insurance.
This method ensures a precise monthly payment estimate for better financial planning.

Example Calculation
Suppose you want to buy a home with the following details:
- Home Price: $350,000
- Down Payment: $70,000
- Interest Rate: 4%
- Loan Term: 30 years
- Annual Property Tax: $4,200
- Annual Insurance: $1,500
Calculation Steps:
- Loan Amount = $350,000 – $70,000 = $280,000
- Monthly Interest = 4% ÷ 12 = 0.00333
- Total Payments = 30 × 12 = 360 months
- PI Payment = $280,000 × 0.00333 ÷ (1 – (1 + 0.00333)^-360) ≈ $1,336.76
- Monthly Tax Payment = $4,200 ÷ 12 = $350
- Monthly Insurance Payment = $1,500 ÷ 12 = $125
- Total PITI = $1,336.76 + $350 + $125 = $1,811.76
This monthly payment includes all principal, interest, taxes, and insurance.
