What is the PITI Calculator?
Compute principal, interest, taxes and insurance on a mortgage. To use the PITI Calculator, enter loan, rate, term, property tax per year, insurance per year; it returns monthly piti, principal and interest, taxes and insurance, and shows them instantly as you type.
Where the PITI Calculator fits
Compute principal, interest, taxes and insurance on a mortgage. The main figure it returns is the Monthly PITI, worked out from the values you enter.
It belongs with the other loans & debt tools. If you are comparing options or checking a result from another angle, try the Mortgage Interest Calculator, Credit Card Interest Calculator or the Interest Per Day Calculator.
How to use the PITI Calculator
- Fill in the fields. You will need Loan ($), Rate (%), Term (years), Property tax per year ($), Insurance per year ($). Take the rate and term from your loan offer. Fees and the rate type change the result. Fields marked optional can stay at zero.
- Read the result. The highlighted box gives the Monthly PITI, and the cards below show Principal and interest, Taxes and insurance. Tables and charts break it down further.
- Test other scenarios. Results update as you type. Change one value at a time to see what drives the answer, and press Reset to go back to the defaults.
Formula and how it works
Example with real numbers
Here is the PITI Calculator using the default values shown in the calculator above:
Inputs
| Loan ($) | 320,000 |
|---|---|
| Rate (%) | 6.5 |
| Term (years) | 30 |
| Property tax per year ($) | 4,200 |
| Insurance per year ($) | 1,500 |
Results
| Monthly PITI | $2,497.62 |
|---|---|
| Principal and interest | $2,022.62 |
| Taxes and insurance | $475.00 |
With these inputs the calculator returns Monthly PITI: $2,497.62. Change any value in the calculator to see how the result moves.
What if you change one input?
Sensitivity check: raising Loan ($) from 320,000 to 384,000 (about 20% higher) and leaving everything else as in the example above changes the results like this:
| Result | Example | After the change | Change |
|---|---|---|---|
| Monthly PITI | $2,497.62 | $2,902.14 | +16.2% |
| Principal and interest | $2,022.62 | $2,427.14 | +20% |
| Taxes and insurance | $475.00 | $475.00 | 0% |
The input that moves the result most is the one to check twice. Change it in the calculator above to test your own case.

Frequently asked questions
