Choose from a range of input types to build your custom calculator. Add sliders so visitors can select values along a range, numeric fields for decimal, integer, or monetary values, and dropdown menus for predefined options.
Include checkboxes for single or multiple selections, picture choice questions with images, and contact form fields to collect names, email addresses, and phone numbers. The editor shows you exactly how your calculator will look as you add and arrange fields.
The calculator builder includes two ways to create formulas. The simple formula builder lets you drag and drop fields into a visual editor, then connect them with operators and functions like addition, subtraction, multiplication, IF statements, and weighted scoring. Results update in real time as you build.
For more advanced calculations, use the Excel-style formula builder. Import your own datasets and build formulas that reference multiple cells, rows, or columns. If you already have calculations working in a spreadsheet, you can recreate them here without starting from scratch.
Match your calculator widget to your website with custom colours, fonts, logos, and button styles. The responsive preview lets you check how your calculator looks on desktop, mobile, and tablet before publishing.
Your custom calculator automatically adapts to the page width when embedded, so it looks native to your site. On paid plans you can remove FreeOnlineSurveys branding entirely.
Get an embed code that works on any website, including WordPress, Squarespace, Wix, Shopify, or custom HTML pages. Paste the code into an HTML block and your calculator widget will appear on the page, resizing automatically to fit the layout.
You can also share calculators directly via link, making them easy to include in emails, social media posts, or messages without embedding.
Gate calculator results behind a contact form to collect email addresses and other details before showing the output. Every lead flows into the built-in contact manager where you can segment, filter, and export.
Add conditional messages that display different content based on calculator results. Show one message for results under a threshold and another for results above it, each with its own heading, description, and call-to-action button.
No coding required. Make custom calculators for ROI, pricing, and estimation tools with formulas, conditional logic, and lead capture.
The formula builder checks for errors as you work, highlighting issues before you publish so your calculator always returns accurate results.
Display results to visitors as they enter data, updating in real time alongside your calculator with charts, progress bars, and formatted values.
Calculators are completely free of tracking cookies and IP addresses are masked by default. Fully compliant with GDPR and CCPA.
Add CTAs to each results block with custom text and links. Show different calls-to-action conditionally based on the calculator output.
