How this calculator works

The risk calculator converts between a percentage of an account balance and a fixed monetary amount. It is the first arithmetic step in planning a position: a monetary budget still needs a stop distance and an instrument value before it becomes a lot size.

A quick visual example

Illustrative inputs · not live prices
  1. Account balance$10,000
  2. Chosen percentage0.5% = 0.005
  3. Monetary budget$10,000 × 0.005 = $50

Replaces the form inputs with this example and calculates the result.

Choose the right inputs

Enter a positive account balance and choose percentage mode or fixed-amount mode. In percentage mode, enter the percentage as 0.5 for half a percent, not 0.005. In fixed mode, enter a monetary amount in the same currency as the balance. The example percentage illustrates arithmetic and is not a recommended risk level.

Understand your result

Percentage mode multiplies balance by percentage divided by 100. Fixed mode divides the amount by balance and multiplies by 100. The result describes one chosen budget. It does not reserve funds, change account settings or account for open positions.

Common mistakes to avoid

A planned budget is not a guaranteed loss ceiling. Stop execution, gaps and costs can change the final outcome. Several positions can also expose the same account at once; this calculator does not aggregate portfolio risk or measure correlations.

Frequently asked questions

Does this tell me the correct percentage to risk?

No. It converts a percentage or amount that you choose; it does not assess your financial circumstances or recommend a budget.

What should I use after this calculation?

Use the appropriate position-size calculator with the budget, a defined stop distance and verified instrument specifications.

Calculation formula

Monetary risk = balance × risk percentage ÷ 100. Percentage = fixed monetary risk ÷ balance × 100.

Worked example

A $10,000 balance at 0.5% corresponds to $50 planned risk. This does not specify a trade size until stop distance and instrument value are known.

Assumptions and limitations

Illustrative percentages are not recommendations. Gap risk, slippage and costs can cause loss beyond planned risk.
