About B2B ROI Calculator

What this site is

B2B ROI Calculator is a free suite of calculators for modelling business investments: ten ROI calculators — general, CRM, SEO, enterprise SEO, marketing, content marketing, marketing automation, customer experience, website and HubSpot — plus three SaaS-metrics calculators for CAC, churn rate and LTV. ROI models run three scenarios (Conservative, Expected, Aggressive) over a 12-month horizon; SaaS-metrics calculators are exact identities.

How it works

Every calculation runs entirely in your browser — the numbers you enter are never sent to a server, and there is no account. Every formula is published on the methodology page, including the ramp-up and payback conventions and each model's stated approximations, so you can audit every number. Assumption fields ship with demonstration defaults marked as such — they are not claimed industry averages, and we do not publish fabricated benchmark statistics.

Why it's free

These are static, in-browser calculators, so our costs stay close to plain web hosting. Every calculator works with no email at all; the one optional step that asks for a work email is the downloadable PDF report, and your details are only shared with a partner if you explicitly tick the partner-offers box.

Who's behind it

B2B ROI Calculator is built and maintained by a small independent team that makes free, no-signup business tools. Questions, corrections or feedback: support@b2broicalculator.com.
