Last updated: 2026-10-28 # Position size calculator How many lots to trade for the risk you choose: balance × risk ÷ (stop in pips × pip value per lot). Pick a WhitePips plan to see the trade against its daily and maximum loss. - **$10** one pip on 1.00 lot of a USD-quoted pair - **0.01 lot** the smallest step on most MT5 symbols - **$4,000** Max Daily Loss on a $100K Edge 1 Step Your figures WhitePips plan (optional) (Sets the balance and shows the plan's loss limits.) Account balance _USD_ Risk per trade _%_ Stop loss _pips_ Risk Stop Instrument The result Position size **—** This trade against the plan's daily loss **—** $0 — Full stop-outs that fit in one day **—** Money at risk **—** Pip value at that size **—** Units **—** Sizes are rounded down to 0.01 lot, the smallest step on most MT5 symbols. Commission is extra: on CFDs it is charged per lot, round turn (see [symbols and commission](https://whitepips.com/symbols) ). ## How it is calculated Lots = money at risk ÷ (stop loss in pips × value of one pip for 1.00 lot) ### Decide the money at risk Your balance multiplied by the share you are willing to lose on one trade. $100,000 × 0.5% = $500. ### Price the stop per lot One standard lot is 100,000 units of the base currency, so a one-pip move (0.0001, or 0.01 on yen pairs) is worth $10 on any pair quoted in US dollars and a converted amount on the rest. A 20-pip stop costs $200 per lot. ### Divide, then round down Money at risk ÷ the stop's cost per lot: $500 ÷ $200 = 2.50 lots. If the stop is hit you lose exactly the amount you decided to risk and no more. ### Pip value per 1.00 lot, by pair USD is the quote **$10** (EURUSD, GBPUSD, AUDUSD, NZDUSD) USD is the base **$10 ÷ price** (USDCAD, USDCHF) Yen pairs **1,000 ÷ USDJPY** (about $6.67 at 150) Crosses **$10 × quote in USD** (EURGBP, AUDCAD) Gold **$10 per 0.10** (100 oz a lot; a $1 move is $100) Worked example ### A worked example on a $100K Edge 1 Step Balance $100,000, risk 0.5% per trade, a 20-pip stop on EURUSD. Money at risk is $500. One pip on one lot is $10, so the stop costs $200 per lot. $500 ÷ $200 = 2.50 lots. A full stop-out at 2.50 lots costs $500, so it would take 8 losing trades in a row to reach the daily limit. That count, more than any single trade, is what keeps an evaluation alive. Balance **$100,000** Risk per trade **0.5%** ($500) Stop **20 pips** ($200 per lot) Position size **2.50 lots** Max Daily Loss **$4,000** Max Loss **$7,500** (Static) The WhitePips rule it meets ### Max Daily Loss and Max Loss On WhitePips CFD accounts both loss limits count open losses as well as closed ones, so a trade that is losing on screen already uses part of the day's allowance. On a $100K Edge 1 Step the daily limit is $4,000 and the Max Loss $7,500 (Static). [The rule, explained](https://whitepips.com/rules#rule-cfd-max-daily-loss) For education. The results are arithmetic on the figures you enter; the contract specification, prices and commission on your platform decide real results. Nothing here is financial advice, and trading leveraged products can lose money. ## Position size calculator: questions **What is a good risk per trade on a funded account?** There is no single right number, and nothing here is advice. Many traders size so that several losing trades in a row stay well inside the daily loss limit. On a $100K Edge 1 Step the daily limit is $4,000: risking 0.5% ($500) a trade leaves room for 8 full losses in one day; risking 2% ($2,000) leaves room for 2. **Why does the pip value change between pairs?** Because profit is paid in the pair's quote currency and then converted to your account currency. On EURUSD the quote is the dollar, so a pip on one lot is $10 with no conversion. On USDJPY it is yen, so the $ value depends on the yen rate. **Does leverage change my position size?** No. Leverage decides how much margin a position ties up, not how much it loses per pip. Two traders with the same lot size and stop lose the same amount whatever their leverage. **Is commission included?** No, the calculator sizes the stop only. On WhitePips CFD accounts commission is charged per lot, round turn: forex $5 on Edge and Instant and $4 on Prime; indices and stocks are free. See [every symbol's commission](https://whitepips.com/symbols) . **Does the daily loss limit count open trades?** Yes. On WhitePips CFD accounts both loss limits count open losses as well as closed ones, so a trade that is losing on screen already uses part of the day's allowance.
