Overview
Calculator from Elfsight builds an interactive cost, quote or estimate calculator on a Squarespace page: visitors move sliders, pick options and see a result computed from formulas you write. It is an embeddable widget hosted on Elfsight's platform rather than native Squarespace code. Field types include sliders, numeric inputs, dropdowns, single and multiple choice (with or without images) and section headings. Formulas support IF/THEN conditions, AND, OR and NOT operators and functions such as SUM, ROUND, MAX and MIN, and one result can feed into another. Conditional logic shows or hides fields based on earlier answers. Switch on submissions and the visitor's inputs and result arrive by email, which turns it into a lead form. Squarespace's form block has no calculation at all, so this fills a real gap.
Key features
- Sliders, numeric inputs, dropdowns, choice fields and image choices
- Formula engine with IF/THEN, AND, OR and NOT, plus functions such as SUM, ROUND, MAX and MIN
- Chained calculations so a subtotal feeds a final total
- Conditional logic to show or hide fields based on earlier answers
- Templates for finance, rent, delivery and product pricing, plus an AI generator that builds a calculator from a written description
- Optional submission with email notification, including sending from your own domain via SMTP
- Colours, fonts, background images and logos set without CSS
Who it suits
Trades and service businesses that quote from a few variables (area, hours, options), agencies with package pricing, landlords and lenders showing rent or repayment estimates, and anyone who wants a lead form that gives the visitor a number before asking for their details.
Honest limits
It is an estimate tool, not a checkout. The result does not flow into Squarespace Commerce, create an order or take payment. Formulas need careful testing with real numbers, and the editor is more involved than most Elfsight widgets, so allow an afternoon rather than ten minutes for anything with conditional logic. Submissions arrive by email or in the Elfsight dashboard, not in Squarespace's form storage or its email campaigns. Free-tier widgets carry Elfsight branding and monthly view limits, and because the calculator loads from Elfsight's servers it disappears if your subscription lapses.
Installation on Squarespace
Build the calculator in Elfsight's editor (or describe it to the AI generator and refine the result), test the formulas, copy the embed code and paste it into a Squarespace code block where you want it. Changes made later in the editor apply automatically.
