How to calculate your mortgage payment in Excel
Quick insights
- To calculate your mortgage payment on a fixed-rate loan in Excel, use the PMT function: =PMT(interest_rate/12, loan_term*12, -loan_amount), where the interest rate is divided by 12 for monthly payments, and the loan term is in years.
- A mortgage payment has four main parts—principal, interest, taxes and insurance (PITI)—but the basic Excel formula is only for principal and interest.
- For advanced mortgage calculations in Excel, you can create an amortization schedule, analyze extra payments to see how they reduce loan balance and interest costs and build a loan comparison model.
Mortgage calculators can be great tools for estimating various costs, clarifying your budget and understanding home affordability. The Chase Mortgage Calculator can help you explore different loan options with specific figures.

Understanding mortgage payments
A mortgage payment is the amount a borrower pays each month to repay a home loan. It generally consists of four main components:
- Principal: The portion of your payment that goes toward reducing the loan balance. Over time, as you make payments, the principal decreases, helping you build equity in your home.
- Interest: The cost of borrowing money from the mortgage provider, calculated as a percentage of the remaining loan balance. Early in the loan term, a larger portion of your payment goes toward interest rather than the principal.
- Property taxes: Taxes charged by local governments based on your home’s value. These are often included in your monthly mortgage payment and held in escrow by your loan provider. Example: You live in Chicago and own a home valued at $300,000, and the property tax rate is 2.1%; property tax would be $6,300 ($300,000 x 2.1%) or $525 per month.ec-property-tax-rates-calculations
- Homeowners insurance: A policy that protects your home and belongings from damage, theft or liability. Loan providers typically require insurance, and the premium may be included in your monthly mortgage payment.
Setting up your Excel spreadsheet
To create a mortgage calculator in Excel:
- Start by setting up a structured spreadsheet.
- In column A, label key inputs such as “Loan Amount,” “Annual Interest Rate,” “Loan Term (Years)” and “Monthly Payment.”
- In column B, enter corresponding values.
Accurate data entry is crucial because small errors can result in incorrect payment estimates. Use Excel’s formatting tools to improve readability such as bold labels, currency formatting for dollar amounts and color coding to differentiate inputs and outputs. By organizing your data effectively, you’ll have a user-friendly calculator that delivers precise results.
The Excel mortgage payment formula
Each simplifies mortgage calculations with the PMT function, which determines the monthly payment. The formula structure is:
=PMT (rate, nper, pv)
- Rate: The monthly interest rate (annual rate / 12)
- Nper: The total number of payments based on regular, constant payments and a constant interest rate. (years x 12).
- Pv: The present value or loan amount.
For example, if you have a $300,000 loan with a 6% fixed annual interest rate for 30 years, the Excel formula would be:
=PMT(6%/12,30*12,-300000)
This formula returns the monthly mortgage payment. The negative sign before the loan amount ensures the result appears as a positive number. To check for errors, verify that you’re using the correct units (monthly rate and total months) and double-check input values.
Using the Excel mortgage calculator formula
Excel's PMT formula is a powerful tool for calculating mortgage payments. Keep in mind that the formula returns your principal and interest monthly payment, excluding taxes and insurance.
Here are some tips for interpreting the results:
- A lower interest rate can significantly reduce your total payment.
- Shorter loan terms mean higher monthly payments but lower overall interest costs.
- Experiment with different loan scenarios to compare affordability.
Advanced mortgage calculations in Excel
For deeper insights into your mortgage, Excel offers advanced calculation tools:
- Amortization schedules: Breaking down each payment into principal and interest components over time.
- Extra payments analysis: Determining how additional monthly payments can reduce interest costs and loan duration.
- Loan comparison models: Comparing different loan options side by side to find the best deal.
In summary
Understanding how to calculate mortgage payments in Excel can help you manage finances. The PMT formula allows for quick payment estimates, loan comparisons and extra payment planning. Additionally, tools like the Chase Mortgage Calculator help homebuyers explore different loan options and determine affordability. Using various tools can empower homeowners to make highly informed financial decisions.
