Embeddable ROI / Cost Savings Calculator

The Problem

Showing a prospect a concrete, personalised number ("here's what you'd save") converts far better than a generic claim — this calculator does that math live, based on inputs your own visitors enter.

About this problem

A generic claim such as 'save up to 30%' is easy for a prospect to ignore, whereas a figure calculated from their own numbers feels relevant. An ROI or savings calculator takes a few inputs, such as headcount, hours spent or current cost, applies your formula and presents the result immediately, with no waiting for a quote.

Businesses usually look for this when they want to qualify visitors on a service or pricing page, or to support a sales conversation with something concrete. The calculator is only as credible as its assumptions, so it needs a clear formula, realistic input ranges and a result that is presented honestly rather than inflated.

What's Included

• A calculator built around your specific value proposition and formula
• Clean, embeddable widget matching your site's design
• Clear, compelling presentation of the result
• Testing with realistic example inputs to confirm the numbers make sense

What's NOT Included

• Deciding the underlying assumptions/formula — that's your call, backed by your own data
• Lead capture integration beyond showing the result (can be added, e.g. "email me this result")
• Ongoing changes to the formula as your offering changes (handled as update requests)

How It Works

1. I take your formula and assumptions and write them out as explicit steps, including the inputs required, their sensible ranges and any fixed values.
2. I implement the calculation in client-side code so the result updates live as the visitor changes inputs, with validation against impossible or empty values.
3. I build the widget's layout and styling to match your site's fonts, colours and spacing, and make it responsive on mobile.
4. I package it as an embeddable snippet that can be dropped into a page without conflicting with your existing styles or scripts.
5. I test with realistic example inputs, including extremes, and confirm the output agrees with the figures you calculate by hand.

In practice: you buy the service, send over whatever access or details the job needs, I investigate and do the work, and you confirm it's resolved before we call it done.

Frequently Asked Questions

How do I add an ROI calculator to my website?

It is built as a small widget you embed on a page. I provide the code snippet and install guidance for your site or platform.

Who decides the formula?

You do. The assumptions need to come from your own data, and I implement them. I can point out if a result looks implausible but cannot validate your business case.

Can it capture visitors' email addresses?

Lead capture beyond showing the result is not included, but a feature such as emailing the result can be added if scoped.

Will it match my site's design?

Yes, I style it to follow your site's look as closely as is practical.

What if my pricing or offering changes?

Changes to the formula or values are handled as update requests.

Does it work on mobile?

Yes, the widget is built to be responsive and is tested at phone widths.
