Calculoid

What it is

Calculoid is a platform for building interactive web calculators, aimed at website owners who want visitors to price a product, estimate a return or work out a loan on the page. Its own words: "Calculoid is a platform for creating interactive web calculators which can be easily publish into your website." It adds that "You do not have to be a web developer to create your own online calculator in just a few clicks."

The home page headline widens the scope beyond calculators: "Web calculators, forms, quizzes and polls made easy", with the promise to "Engage users, collect leads, accept payments". The site is offered in English, Chinese (Simplified), Czech, French, German, Italian, Japanese, Portuguese, Russian and Spanish, and the site carries integration pages for Redmine, Mautic, Joomla, Drupal and WordPress, plus a changelog, documentation and a product sheet for people who want the detail before signing up.

What you build and how

The build is a short sequence on the home page. Choose one of the professional templates or start from scratch, customize fields, calculation and design "in an intuitive drag & drop wizard", publish with the embed code or an iframe, generate leads by letting a visitor submit contact details to get the result, and accept PayPal and credit card payments. The page frames it as "Web calculator, quiz or survey in a few clicks", so quizzes and surveys are within scope as well as calculators.

The builder's field types are listed on the web calculator builder page:

• Sliders and text fields for value input.
• Checkboxes and round boxes for options.
• Formula fields for calculations.
• A payment field for Stripe or PayPal payment.
• A send-result field for sending a quote and generating leads.
• Graphs and charts to display calculated values.

The formula layer is the part to look at closely. The company says Calculoid calculates "like in Excel Spreadsheet", and in addition to basic arithmetic you can "use popular Excel formulas, such as IF, sin, cos, log and others." It claims coverage "From basic 1+2 to complex volume discounting". For a pricing model with tiers or quantity breaks, that is the relevant capability: an IF-based structure inside a formula field rather than a separate rules engine.

Payments and lead capture are the commercial core. The payments section says: "Connect calculator to your Stripe or PayPal account and get paid online. Streamline your sales process with self-service pricing calculators and online payments." The lead section says visitors can send calculation results to their own email, so the site owner gets a lead for a mailing list, and adds that you can "even use Calculoid as a a full-featured conversion form". That last sentence is what places the product in the forms category: a calculator with a send-result field is also a contact or order form. A template on the site, Online Store, is described as "Create a simple online store, calculate the final price and get paid online."

The template list is concrete: Pricing Calculator, ROI Calculator, Loan & Debt Calculator, Costs Calculator, Saving Calculator and Online Store. Each carries a one-line description. The ROI template is for calculating "ROI of your products and services" and collecting customer leads, the Loan & Debt template covers "insurance, loans, debts", and the Saving template sends an email to collect the lead. The Pricing Calculator and Online Store templates are both marked "Online payments included". Solution pages in the footer add a medical and dosing calculator, payment, finance and price calculator builders, and a Redmine e-commerce and lead-generating solution, which shows how far the same building blocks are stretched.

Design is described as branding the calculator "so it looks like a native part of your website", and the reviews on the page mention customizing the look with CSS. The page states that all calculators are "100% mobile and touch-friendly" and that calculators and transferred data are "secured with SSL encryption."

For publishing and integration, the page says calculators "can be published to any website or online application and easily integrated with your information system using Zapier or REST API webhooks." The home page's top strip lists "Zapier integrations", and the footer names Redmine, Mautic, Joomla, Drupal and WordPress integration pages. Results are tracked: a blog item dated 13.01.20 describes a Submissions overview with more detailed statistics based on web calculator submissions, released in beta to all users.

What the pages say about plans, claims and support

The site offers a 30-day free trial: "Test all features in the 30-day free trial", with "No credit card or installation needed", and the sign-up buttons read "Sign Up Free". Plan names and prices sit on a separate Pricing page, not on the home or builder pages.

The trial detail matters because of one reviewer. On the home page, a Capterra reviewer who works in non-profit IT writes that they used the free capability and "unfortunately those features were no longer available. We have to make a purchase in order to use it." In other words, the free access is a trial, and a calculator you keep running is a paid one.

The site displays "Calculoid on Capterra overall 4.5/5 (4 reviews)". Individual reviews carry ratings for ease of use and customer service. One reviewer who has used it for over a year calls it "a little pricey, but mostly worth it" and says "customer support is quick and helpful". Another likes the ease of installation and the ability to design and customize, but notes "It takes some time to load on our web page". A third found the administration with Easy project complex. The company chose to show this set, including the critical lines, which is a point in its favor.

Who it suits and who it does not

Calculoid suits a small business, consultant or agency that wants a pricing or ROI calculator that also takes a payment or captures an email. Stripe and PayPal fields, emailed results and a Zapier or webhook path out cover the quote-to-sale chain without custom code. Teams that run Redmine, Mautic, Joomla, Drupal or WordPress have integration pages written for them, and a site with an international audience can serve visitors in any of the languages the site itself is offered in.

It is a weaker fit if you want a visual app builder with its own database and user logins, because the pages describe embeddable calculators, not full applications. Quizzes and surveys are in scope, but the field list is built around calculation, so a long research survey is not what it is designed for. The reviews also point to a practical check: one reviewer saw slow loading on their page, so test load time on your own site during the 30-day trial before you roll a calculator out widely.
