Collect the numbers
Add a Number or Slider field for each quantity you price by, such as square footage or a monthly bill.
Coming 2026Calculations arrive in 2026. You can show a result today with conditional logic or Zapier.
Feature
A form with calculations takes the numbers a lead enters, applies a formula and shows a result such as a price estimate. The lead receives something useful in return for their details, which gives them a reason to finish.
A form with calculations is a form that works out a figure from the lead's answers and shows that figure to them. A window replacement form, for example, can multiply the number of windows by a price per window and present the estimate on its final screen.
You can build a quote calculator that shows a price range today. The method uses endings and conditional logic. A form can have several endings, each ending has its own rules, and a rule can test whether a number is greater or smaller than a value. A homeowner who enters more than 10 windows sees the ending written for large projects, and everyone else sees the standard estimate.
A cost calculator form sends an exact price today by passing the lead to Zapier, where the calculation is done and the result is emailed. This suits a price that needs precise arithmetic, or one that your team wants to check before the customer sees it. Growform's own email alerts go to you and your team, so the message to the customer is sent from Zapier.
Calculations inside the form are planned for 2026, which will make Growform a full calculator form builder. Until then, number fields, sliders and buttons collect the inputs, and the two methods above present the result.
Add a Number or Slider field for each quantity you price by, such as square footage or a monthly bill.
Add an “In-form ending” for each price range and write the estimate for that range into it.
Give each ending a rule based on the number entered. Endings are checked in order, and the last one is the fallback.
Where a precise figure is needed, connect the form to Zapier, calculate the price there and email the result.
An estimate on the final screen is something the lead receives in exchange for their contact details.
A homeowner who has seen a price range for a new roof comes to the call with that range in mind.
The rules that choose an ending can also redirect a project outside your range or mark the lead as disqualified.
The quantities the lead entered are saved with the lead and passed on through email alerts, webhooks and Zapier.
Calculated fields are planned for 2026, and the ending and Zapier methods work on every plan today.
Calculations are coming in 2026. Today a form can show a different ending for each range of answers, or pass the numbers to Zapier for the calculation.
