About B2B ROI Calculator

What this site is

B2B ROI Calculator is a free suite of 19 calculators for modelling business investments: twelve ROI calculators — general, CRM, SEO, enterprise SEO, marketing, content marketing, marketing automation, customer experience, website, ecommerce, B2B ecommerce and HubSpot — three unit-economics calculators for break-even, contribution margin and ROAS, and four SaaS-metrics calculators for CAC, churn rate, LTV and the LTV:CAC ratio. The investment models run three scenarios (Conservative, Expected, Aggressive) and report a 12-month result; the general ROI, unit-economics and SaaS-metrics calculators are exact formulas.

How it works

Every calculation runs entirely in your browser — nothing you enter is sent while you calculate, and there is no account (downloading the optional PDF report sends your email and a summary of your inputs; the privacy page says exactly what is kept). 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 Assumption fields ship with demonstration defaults marked as such — they are not claimed industry averages, and we do not publish fabricated benchmark statistics.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.
