Every plan leans on one big assumption. This tool puts a dollar figure on what happens if yours doesn't hold — itemized, line by line, from your own numbers.
60 seconds · free · your numbers never leave your browser
Nothing is invented and nothing is hidden. Every line of the receipt shows exactly how it was calculated from what you typed — and there's a plain-words breakdown under it.
Walk in with a figure instead of a feeling. Copy the breakdown straight into Slack, a memo, or the deck — the number does the arguing.
From the team behind the data-backed edge, read every Tuesday by global decision makers.

Is any of it first-party — your own customers, your own data?
