Transforming customer journeys with in-page quotes and calculations

Calculating for success

Boost sales and engagement

In today’s fast-paced digital world, businesses need tools that engage users, simplify decision-making, and drive conversions.

One of the most powerful tools growing in usage right now is the in-page calculator. With a little JavaScript magic, you can turn complex calculations into an interactive experience that delights users - and grows your business.

Make Decisions Easy for Your Customers

Customers often hesitate when a product or service feels complicated or uncertain. An in-page calculator removes the guesswork. Whether it’s calculating costs, savings or quotes, giving users instant answers builds confidence and reduces friction in the buying process.

Increase Engagement and Time on Site

Interactive tools keep visitors on your website longer. Unlike static pages, calculators invite users to click, type, and explore. The result? Higher engagement, stronger brand recall, and better chances of conversion.

Generate Leads While Adding Value

Calculators can double as lead generation tools. Asking users for their email in exchange for a detailed calculation gives them value upfront and provides you with a warm lead. This creates a win-win scenario - your users get instant insight, and you gain actionable business intelligence.

Recommending specific and applicable products leads to improved engagement and sales

Selecting a heating product is significantly complicated by the need to determine a room's heat loss in kWh.

Seeing that both engineers and customers were needing help choosing appropriate products, Dimplex chose to build their Heat Loss Calculator to give immediate recommendations and actions based on hard facts and measurements.

Fast, accurate heatpump quotes

With CRM data collection for ongoing engagement

To increase their competitive edge and claim more of the heatpump market, EDF Energy commissioned a heatpump quote calculator.

Customisations to the Drupal site behind it allowed the EDF team to specify all the parts, processes and costs involved, making it possible to give the customer specific and accurate final cost breakdown. Incredible ease of use for those involved on each side of the quote!

With contact and quote details stored into the CRM for follow-up, EDF have a fantastic new store front for their ASHP offering.

Rapid estimates help buyers plan projects faster

While there are numerous costs when building a high quality deck, the most substantial is the boards themselves. Rather than leave customers to scratch away at paper, or jump to another site to work things out, Millboard commissioned a pricing calculator to streamline the estimation and purchase experience.

Thanks to the quick access to pricing information, they saw customers staying longer on the site.
