Free calculators
Prop-firm calculators, free and without a login
Drawdown, daily loss, position size for forex, gold, NAS100 and US30, sizing in cTrader’s own units, consistency, trailing drawdown and the evaluation itself. Each one runs in your browser on the numbers from your platform, opens with a worked example, and says what it assumes.

Prop-firm challenge calculator
How many trades a target takes at your win rate and reward-to-risk, and how many losses in a row your risk per trade survives before each loss line.

What every calculator here has in common
Each one takes the numbers your platform shows - the initial account size, the balance and equity at the firm’s reset, equity now - and does the arithmetic the firm’s rule describes, with no slice held back. That is the number every other calculator in this category shows, and it is slightly more room than a risk engine that reserves for slippage would gate on. Every page lists its assumptions in full, and every page says the same thing about the firm: its own measurement, on its own server, in its own time zone, is the one that ends an evaluation.
The rules themselves - which firms measure the day from balance and which from equity, when each firm’s day resets, what a trailing floor does - are on the prop-firm pages, with a source and a checked date for each figure, and the words are in the glossary.
