Unkillable Tools / Calculator / ROI calculator for B2B websites
An ROI calculator is the highest-intent page a B2B site can have. Someone modelling your product's return has already decided they want it to work.
The classic time-saved model. Change the team size.
Change the rates, the labels and the maths to match your business, then export it as a single HTML file you paste into your site. Free, no account, and it keeps working whatever happens to us.
Open the builderEvery B2B purchase over a certain size requires someone internally to justify it to someone else. An ROI calculator writes the first draft of that argument, in the buyer's own numbers, without a salesperson present.
Three outputs do the work: net annual benefit, payback period in months, and hours returned. The payback figure is usually the one that gets quoted internally, because "it pays for itself in seven weeks" survives being repeated in a meeting.
Default the inputs low. A calculator that claims a 900% return reads as marketing and gets discounted to zero; one that shows a solid, plausible number gets forwarded to a finance team.
Include the costs honestly — subscription plus setup, not just the licence fee. Buyers who spot an omitted cost stop trusting the whole model, and a calculator that includes implementation cost and still shows a strong return is far more persuasive.
ROI calculators tend to live on high-traffic pages and get linked from sales decks, which is exactly the usage pattern that burns through a monthly impression allowance. Discovering that your sales team's favourite link has turned into a dead button mid-quarter is an avoidable failure.
There's a procurement angle too: a self-contained file introduces no third-party data processor, which removes an entire section of the security questionnaire when an enterprise prospect asks what runs on your site.
You can add a lead form under the result with Pro, but we'd suggest showing the figure first. Gating a number people can estimate themselves mostly harvests fake email addresses.
Yes — add derived-value fields for compounding, the way the solar template does with its escalation factor.
Yes. Export it as a full page and it runs from a local file with no internet connection at all.
Hosted calculator builders charge $5–$115 a month and stop rendering when you exceed your monthly impressions. This one exports a file that runs on your own site and cannot be switched off.
