Risk Per Trade Calculator
Estimate a risk-per-trade dollar cap from account size, drawdown room, daily loss limit, stop distance, unit value, and buffer values you enter.
Check the source first: this is an arithmetic planning worksheet. It has no firm presets, no strategy calls, no rankings, and no recommendations. Verify current official rules, drawdown logic, reset clocks, payout limits, and instrument values directly before relying on any number.

Formula Notes
- Account-percent cap: account size x entered account risk percent / 100.
- Drawdown-room cap: remaining drawdown room x entered drawdown risk percent / 100.
- Daily cap: if a daily loss limit is entered above zero, it is included as another cap.
- Lower arithmetic cap: the lowest positive cap among account-percent, drawdown-room, and daily-limit inputs.
- Risk per stop unit: stop distance x dollar value per stop unit.
- Estimated units: lower arithmetic cap minus buffer, divided by risk per stop unit. The result is not rounded into a tradable order size and does not account for margin, liquidity, or product rules.
- Losing trades to drawdown: drawdown room divided by lower arithmetic cap, from entered values only.
What This Calculator Does Not Know
This calculator does not know whether a firm’s drawdown is static, trailing, end-of-day, intraday, balance-based, equity-based, realized-only, or affected by commissions and fees. It also does not know margin requirements, liquidity, product volatility, open-position rules, scaling rules, news restrictions, consistency rules, payout review rules, or whether any trade should be taken.
Privacy And Input Handling
The calculator is designed to run in the browser from values typed into the form. The form has no action URL and the buttons use client-side math only. Do not enter personal data, login details, brokerage credentials, payment information, tax details, or live account identifiers into any public calculator.
Future Firm Presets Need Current Sources
This calculator has no firm presets. Any future firm-specific preset should cite current official firm rules, help-center pages, account specifications, dashboard notices, terms pages, or official announcements. It should identify the firm, program, account stage, account size, asset class or platform scope, drawdown model, daily loss rule, source URL, checked date, and confidence label.
Public chatter, trader complaints, review-site comments, affiliate pages, Discord posts, Telegram posts, screenshots, and social posts should not populate risk-per-trade math.
Corrections And Updates
Readers and firms can flag stale rule sources, changed drawdown logic, wrong unit values, missing product distinctions, or formula errors. BestProps should update the calculator notes when formulas, defaults, source hierarchy, or firm preset rules materially change.
