Prop Firm Startup Cost Calculator

Model what a technology contract can actually cost over 12 months. Change the assumptions below to compare fixed fees, revenue share and per-account pricing on the same basis.

This is a planning model, not a vendor quote. Enter contractual figures from the vendor you are evaluating. Taxes, payment processing, legal, staffing, market data and other operating expenses may sit outside the technology contract.

Technology assumptions

Setup fee (€)

Monthly minimum (€)

Revenue share (%)

Expected monthly revenue (€)

Active accounts

Cost per active account (€)

The model uses the greater of monthly minimum or revenue-share cost, then adds per-account charges.

12-month model

€0

Estimated first-year technology cost

€0 average monthly cost including setup

0% of modeled annual revenue

€0 recurring cost per month under these assumptions

Why contract structure matters

A low onboarding fee does not necessarily mean a low total cost. Revenue share can be attractive during launch because cost follows sales, but it can become the largest technology expense as a firm grows. A fixed monthly contract behaves differently: the initial commitment can be higher, while the effective technology cost as a percentage of revenue can fall with scale.

Use the calculator during vendor due diligence

Ask each provider for enough information to model at least a low, base and high-growth case. Include minimum monthly commitments, revenue-share definitions, account charges, platform charges and mandatory add-ons. Then compare the same 12-month assumptions across vendors rather than comparing headline setup fees.
