GBP/USD Position Size Calculator
GBP/USD — 'cable' — trades like a faster version of EUR/USD: same $10 pip value per standard lot for USD accounts, but wider daily ranges that demand wider stops and therefore smaller lots at equal risk.

GBP/USD pip value and lot size
One pip on GBP/USD is 0.0001, and a standard lot is 100,000 pounds, so one pip is worth exactly $10 per standard lot when your account is in USD. A 40-pip stop with 1% risk on a $10,000 account gives $100 ÷ (40 × $10) = 0.25 standard lots.
With a GBP account the pip value is £-denominated by definition of the quote; for EUR and other account currencies the calculator converts the $10 value at current reference rates, and you can override the rate manually to match your broker.
Sizing for cable's volatility
GBP/USD routinely moves 30–50% further per day than EUR/USD, and it spikes around UK data and Bank of England decisions. Day traders typically need 20–40 pip stops, swing traders 100–200. The correct response to a wider stop is a smaller lot size, not a bigger risk budget — run your numbers above before every trade.
Frequently asked questions
How much is one pip worth on GBP/USD?
With a USD account, one pip (0.0001) is worth $10 per standard lot, $1 per mini lot, and $0.10 per micro lot — the same fixed structure as EUR/USD.
What lot size for GBP/USD with a $5,000 account?
At 1% risk ($50) with a 30-pip stop: $50 ÷ (30 × $10) ≈ 0.17 standard lots, i.e. 17 micro lots. Enter your own stop distance above for the exact figure.
Is GBP/USD riskier than EUR/USD?
Per pip the money risk is identical — what differs is volatility. Cable's larger daily range means wider stops, which the position size formula compensates for with smaller lots.
