FAQ
Equity Calculator questions
Does this model funding rounds and dilution?
No. The Equity Calculator is for the initial split among co-founders based on contribution. It doesn't model investor rounds, option pools, or dilution waterfalls — use Cap Table for that.
What does 'foregone salary' mean?
The market salary you could be paid somewhere else but are giving up to work on this startup. Someone leaving a $200k role to take $50k contributes $150k of foregone salary per year — real economic skin in the game.
Can I add more than the founders limit allows?
No. Nautis caps the number of founders per calculation. Run two calculations or merge similar contributors.
What if a founder joins later?
Add them with a Join Date after the relevant milestone (Idea Stage, MVP, or Funding). The points system reduces their share of time-based contributions accordingly.
Can I share the result with my lawyer?
Use Export to generate a downloadable file with the full breakdown — names, inputs, points, percentages, and the questions answered.
Will Nautis send the file to investors automatically?
No. Sharing is manual. Either invite teammates via Shared Access or download and email the export.
Is the model opinionated?
It's based on widely used contribution-weighting frameworks. Every input is transparent so you can override anything you disagree with.
Can I share without giving edit rights?
Yes. Shared access is granular — view-only is the default unless you grant edit.
