Do these calculators create an account?
No. They run in the page. The hosted journal is a separate 7-day trial.
Tools
Calculators you can use before an account.
Nine tools, all free. They answer tick dollars, contract count, R, a trailing floor, a consistency percent, a payout split, expectancy, and a sample fee. Statement Check is the one that reads a file. The others read the fields on the page. A blank field, a zero where the formula needs a positive number, and a negative number each stop with a message under the result. Win rate and payout split stay between 0 and 100. Position size rounds down to whole contracts, and it will say when zero contracts fit instead of showing a fraction or a negative size. Nothing here submits an order or a payout request. When you want the same arithmetic on your own fills, the journal imports the CSV and keeps the preset on the account. The October sample is labelled sample data if you would rather click through a full book first.
Before you size
Tick value and position size answer a contract question. Risk and reward turns that stop into dollars. None of them know your firm’s trail until you compare the dollar risk with the room on the dashboard you actually trade.
Prop-firm arithmetic
These three use numbers you type or a sourced preset. A preset fills the fields and links the firm’s article. Editing the field only changes this page. It does not change the account.
The book, in the browser
Expectancy is the average trade if the win rate and the averages hold. The fee calculator prices a dated schedule so a file with no commission column is not a surprise. Statement Check reads a CSV locally and does not upload it.
FAQ
What happens if I leave a field blank?
The page asks for the missing number. It does not treat a blank as zero and it does not print a negative floor, contract count, or payout.
Are the presets the firm’s rule?
They copy a distance from the article linked under the chip, reviewed Oct 2026. The firm can change the plan you bought. Their dashboard stays official.
Which file should I check?
The export your platform already offers: Tradovate Orders, NinjaTrader executions, Rithmic order history, or a TopstepX trades CSV.
