An estimate you can argue with.
Every assumption is on screen and editable, the arithmetic is shown step by step, and the number you get out is only as good as the numbers you put in — which is true of every ROI calculator and stated on very few of them.

If you disagree with the reduction assumption
That is the input to push on, so here is the answer across its range with everything else unchanged. The rest of the model is arithmetic you can check; this row is the judgement.

An estimate, and it is labelled one everywhere it appears.
Under this site’s own policy an unlabelled figure is a fabricated claim, and that applies here more than anywhere. The label sits above the number rather than beneath it, because a reader who sees the figure first has already taken it as fact by the time they reach the caveat.
The defaults are set low on purpose. A calculator whose defaults flatter the answer is a slide rather than a tool, and the first thing a sceptical buyer does with one is halve every input to see whether the case survives. This one is designed for that to be easy.
What it does not know
It has never seen your engagements. It does not know how much of your research time is on jurisdictions inside declared coverage, how much of your review is judgement that will not move, or what your onboarding costs. Those are the three things that decide the real answer.
Which is why the reduction share is an input rather than a constant, and why the sensitivity table exists: it shows what happens when the number you doubt is the number you set.
Check the coverage first.
The addressable share is the input that quietly decides the answer, and it depends on how much of your work is in jurisdictions the product actually covers. That is published per country, gaps included — start there rather than with a percentage.
Ask, and you will get a figure somebody stands behind.
Prices are not published yet, so a conversation is currently the only way to get one. Everything that protects you is in every tier regardless of what it costs.
