Risk Per Trade Calculator for Futures Traders

Last updated: April 9, 2026

Turn a stop width into a whole-contract size cap without doing the tick-value math by hand. This tool is built for futures traders who care about practical position sizing, not just percentage-theory formulas.

Calculator

Risk Per Trade Calculator

Pick a market, define the stop, and set the risk budget. The calculator converts that into a whole-contract size cap and flags when a micro contract would fit better.

Market preset

Preset mode auto-fills dollar-per-point and tick size for common futures contracts.

Dollar risk budget ($)

This is the maximum loss you are willing to take on the trade.

Entry price

Use the actual entry you expect, not a rounded estimate.

Stop price

The calculator uses the distance between entry and stop to price the trade risk.

Dollar value per point

Editable only in manual mode.

Tick size

Used to show tick distance alongside point distance.

Estimated round-trip costs ($)

Use this for commissions plus slippage if you want a more realistic estimate.

Optional helper: derive the budget from account size × risk %

Account size ($)

Only used if the direct dollar budget is blank.

Risk % per trade

Example: 0.5 means half a percent of account size.

Pasteable explanation

This is useful when you want to explain sizing logic to yourself or someone else without redoing the math in chat.

How to use it

Choose the futures contract you actually plan to trade.
Enter the maximum dollars you are willing to lose if the stop gets hit.
Enter the real entry and stop prices, not an estimated number of ticks.
Add estimated round-trip costs if you want the calculator to be stricter.
Use the output as the cap, not as an obligation. If the number feels too large for the setup quality, size down further.

Preset notes

What the preset is doing
Each preset only provides the point value and tick size. It does not decide whether the stop is sensible, whether the market is liquid enough, or whether the setup deserves that much risk.

ES and NQ: useful when the move quality is strong and you want to see whether a full-size contract still fits your budget.
MES and MNQ: often the cleaner choice when the stop is too wide for a mini-sized risk budget.
GC, MGC, CL, and MCL: included because point values move very differently from the index products and traders often mis-size them by memory.

FAQ

Why does the calculator round down?

Because the goal is to stay under the risk budget, not to come close to it. Futures contracts are indivisible, so the safe answer is the largest whole number that still fits.

Should I include fees and slippage?

Yes, if you want a more realistic sizing number. Leaving costs at zero makes the math cleaner, but it can overstate the true room available.

What if the tool says zero contracts?

That means the stop is too wide for the current dollar budget. Tighten the stop, use a smaller product, or reduce the idea to a micro contract.
