Total position risk calculator

Add modelled losses for up to eight positions and compare them with your account budget. See remaining headroom or an excess.

Start with an example

Capital 10,000 USD, limit 3%, modelled losses 100 and 75 USD: total 175 USD (1.75%), remaining budget 125 USD.

Calculation inputs

Changing inputs recalculates the result. Use account currency for amounts unless a field names another unit.

How to interpret the result

Results appear when the calculator starts.

This adds stop-loss scenarios; it is not maximum possible loss, VaR or a correlation model. No amounts are reduced for assumed hedging or diversification. Include costs and assumed slippage in each position’s loss amount. Gaps and simultaneous deterioration in execution can produce a larger loss.

How the result is calculated

Total modelled loss = amounts for positions 1–8. Percentage = total / capital × 100%. Budget = capital × limit % / 100. Headroom = budget − total; a negative amount means the budget is exceeded.

Worked example

Example: capital of 10,000 USD and your own 3% limit give a 300 USD budget. Positions with modelled losses of 100 and 75 USD total 175 USD, or 1.75% of capital. Budget headroom is 125 USD. Adding a position with a modelled loss of 150 USD raises the total to 325 USD and exceeds the budget by 25 USD.

Inputs before results

Where do I find this calculator’s inputs?

You need reference capital, your own limit and each position’s modelled loss in one currency.

Loss amounts, rather than marginsFictional example. Modelled loss for position A: 100 USD; Modelled loss for position B: 75 USD; Combined modelled loss: 175 USD; Own budget: 3% of 10,000 USD: 300 USD; Budget remaining: 125 USD. Conclusion: add planned losses in the same currency, rather than notionals or margins. 3% is this exercise’s fictional limit.ILLUSTRATIVE DIAGRAMModelled loss for position A100 USDModelled loss for position B75 USDCombined modelled loss175 USDOwn budget: 3% of 10,000 USD300 USDBudget remaining125 USD

Balance, equity and used margin

Read current account amounts in the same currency. Balance, equity including open P/L, and free margin describe different quantities.

For the loss budget, deliberately choose balance or equity and keep that definition throughout the plan. In the margin calculator, enter current equity and margin already used by other positions. Do not substitute free margin for equity or count the new position’s margin twice.

Your modelled loss limit

The risk percentage is your own assumption relative to the entered capital. Take it from your plan; an instrument specification cannot select it for you.

The example 1% or 3% is for practice and is not a recommendation. A cash budget does not guarantee the closing result: a gap, conversion-rate change or worse execution can increase the loss.

Modelled loss for each position

For each position, record volume, planned stop, per-lot pip value in account currency, separate fees and assumed slippage. Transfer the modelled loss from position sizing or calculate it using the same units.

Each field represents one position; enter 0 for an unused slot. Enter losses as positive amounts. Do not substitute required margin. The sum does not model correlation or reduce risk for an assumed hedge.

One plan for the complete calculation

After confirming the complete chain from pip value to portfolio, collect assumptions and results in one plan. It is not saved automatically. Changed portfolio inputs or an expired draft invalidate the previous plan.

The plan needs JavaScript and a confirmed draft of the complete chain. Individual calculator formulas and examples remain available without JavaScript.
