Three risk tools. One clearer decision.
Calculate a risk budget, position size and risk/reward ratio for ES, NQ, YM, RTY, MES and MNQ. No account required.
- Calculated locally in your browser
- No input data is sent

In short
These calculators turn a risk budget and price levels into readable outputs: dollar risk, whole-contract size, risk/reward ratio and theoretical breakeven win rate. Fees, slippage and each prop firm’s rules must still be checked separately.
Real-time calculation

Every result updates as soon as you change a value. No amount is stored.
Risk budget calculator
Convert an account percentage into a dollar amount, then see how many whole contracts fit that budget for a given stop.
Enter a strictly positive value.
Mathematical example only, not a risk recommendation.
Example: on ES, 5 points equal 20 ticks.
Tick size, tick value and point value checked against official CME product pages.
Formula used : Account size × risk (%); contract risk = distance × selected unit value; contracts = budget ÷ contract risk.
Position size calculator
Find the whole-contract size from your dollar budget and the actual distance between entry and stop.
Enter a strictly positive value.
Enter a strictly positive value.
Use the contract’s quoted price increment.
Use the contract’s quoted price increment.
Tick size, tick value and point value checked against official CME product pages.
Formula used : Contracts = risk budget ÷ risk per contract, rounded down. No dynamic margin estimate is displayed.
Risk / reward calculator
Check that stop and target sit on opposite sides of entry, then measure the ratio and theoretical breakeven threshold.
Use the contract’s quoted price increment.
Enter a strictly positive value.
Use the contract’s quoted price increment.
Use the contract’s quoted price increment.
Tick size, tick value and point value checked against official CME product pages.
Formula used : Ratio = target distance ÷ stop distance. Theoretical breakeven excludes fees, commissions and slippage.
Reference data
Values used for each contract
Each card separates the minimum tick size, its monetary value and the value of one full point. Margin requirements are not shown because they vary by broker and prop firm.

Risk budget
The chosen percentage is applied to the entered account size.
Budget = account × percentage ÷ 100
Risk per contract
Distance can be entered in points or ticks. The selected unit determines the monetary value used.
Contract risk = points × point value, or ticks × tick value
Whole-contract size
The budget is divided by one contract’s risk, then rounded down.
Contracts = floor(budget ÷ contract risk)
Breakeven threshold
The theoretical rate does not include execution costs.
Breakeven = 1 ÷ (1 + ratio) × 100
Frequently asked questions
What to know before using a result
What is the difference between a tick and a point?
A tick is the smallest quoted movement. A point is a full 1.00 move. On ES, one tick is 0.25 point and $12.50, while one point is $50.
Are calculations stored?
No. All calculations run locally in your browser, and this page does not send the values you enter.
Are fees and slippage included?
No. Results exclude commissions, platform fees and slippage. Add those costs to your own risk plan.
Can I use these tools for a prop firm?
Yes, as a planning aid. Contract limits, drawdown and the prop firm’s official rules always take priority.
Why does the result show zero contracts?
Your budget is below the risk of one contract with the entered stop. Check the inputs or compare a micro contract without artificially increasing risk.
Why is required margin not calculated?
Margin changes by broker, session and prop firm rules. A fixed value would quickly become misleading and must be checked at the source.
Then compare the result with Phidias rules
The calculators provide a mathematical estimate. Drawdown, contract limits and applicable terms remain those published by Phidias when you purchase.
