Cost calculator
The cost of an unprovable number.
When a result cannot be reproduced on demand, the cost is not the number itself — it is the hours, the people and the back-and-forth every time it is questioned. Enter your own figures and this page makes that operational cost visible.
Every estimate is worked out in your browser from the values you enter. It is illustrative — not a benchmark, not a saving, and not a return.

Primary sources of operational friction
- The number crosses 3 systems, so nobody owns the full trail.
- The formula changes about 2 times a year, so an old result may no longer match today's logic.
- Reconstruction pulls in 2 people each time, and one of them may have moved on.
- Each reconstruction takes around 3 hours of manual work.
Potential evidence gaps
- Which version of the formula produced a past result may not be recorded.
- The exact inputs a system received may not be captured at the moment of calculation.
- A portable record you can hand to a client or reviewer may not exist yet.
- For higher-value calculations, there may be no signed proof the result was not altered after the fact.
- Based on the values you entered.
- Illustrative estimate.
- Not financial, legal or compliance advice.
These figures reflect only the numbers you typed and the simple arithmetic shown under each card. They are not a benchmark, a saving, or a return — a receipt does not automatically remove any of this work, and no outcome is promised.
If any of this looks familiar, the next step is to see what a verifiable receipt captures.
Everything is calculated in your browser from the values above. Nothing is sent anywhere and nothing is saved.
