How does this calculator work?
A project price should cover visible and invisible work: discovery, communication, preparation, delivery, testing and close-out.
Practical use
Calculate the base cost first, then add revision and risk buffers. Margin is added as a share of the final price, not as an arbitrary percentage of cost.
Limitations
When scope is uncertain, limit included revision rounds and define chargeable changes.
