What Is the Google Mortgage Calculator Tool?
Google’s built-in mortgage widget provides instant P&I results directly in search. This lightweight clone delivers the same speed and accuracy on your own site, improving dwell time and lead capture without sending traffic away.
It calculates principal & interest only—perfect for quick comparisons before users apply for pre-approval.
How to Calculate Mortgage Payment Like Google (Example)

- Set down-payment percentage—Google defaults to 20%; adjust to 0% for VA or 3% for first-time buyer.
- Select the term you see in Google’s drop-down (15- or 30-year fixed).
- Input the rate displayed on Google’s rate card, then click “Calculate” for instant P&I.
