FAQ
Why is this a preview?
This calculator uses a simplified model while a more granular version is finalized.
Are these estimates exact?
No. They are directional so you can see the size of the leak before refining assumptions.
Can I change the assumptions?
Yes. Adjust the inputs to reflect your business and rerun the numbers.
Why use a range instead of a single number?
Ranges reflect uncertainty and help you stress-test best and worst cases.
Does this include profit?
Use the gross margin input to translate revenue impact into profit impact.
