Prop Firm Startup Cost Calculator

Compare the same software contract under downside, base and growth assumptions. A model that looks cheap at launch can become expensive at scale, while a high fixed commitment can be painful if volume arrives slowly.

Planning model, not vendor quote. Enter written commercial terms. Unknown charges should stay outside the result until confirmed rather than being treated as zero.

Use the stress test before comparing vendors

Ask each provider for the exact calculation base of any percentage fee, minimum commitment, account definition, included modules, platform charges and third-party pass-through costs. Then run the same downside, base and growth assumptions for every proposal.
