Alpari FX Trading Calculators

Our forex trading calculators cover margin, pip value, profit/loss and risk percentage, and can help you quickly and easily calculate trades and manage your risk.

Risk percentage calculator

Our risk percentage calculator determines your lot size based on the percentage of your balance that you're willing to risk. Firstly, select your account currency and currency pair. Then add your stop loss level in pips, your balance amount and the percentage that you are prepared to risk, and click calculate.

View the formula used in this calculation

(Percentage risk x balance x (account/quote currency) / stop loss in pips) / (0.0001 x 100,000)

(Percentage risk x balance x (account/quote currency) / stop loss in pips) / (0.01 x 100,000) (for JPY)

View Example

In this example we have selected a risk percentage of 5%, a stop loss of 100 pips and a balance of 10,000 USD.

Account currency = USD
Currency pair = GBP/CHF
Opening price = 2.1443
Closing price = 2.1452
Account/quote currency= USD/CHF = 0.907029
Lot size = (5 x 10,000 x 0.907029 / 100) / (0.0001 x 100,000) = 0.453515

Our profit/loss calculator helps you estimate the potential profit or loss of your proposed trade. To calculate your profit/loss, choose your account currency and currency pair, input the opening and hypothetical closing prices, select buy or sell, and then enter the lot size and click calculate. Note that the yen is quoted to three decimal places and all other currencies are quoted to five decimal places. Please remember that this is just an estimate and is not guaranteed.

Result in pips

When buying: (Closing price – opening price) / 0.0001
When selling: (Opening price – closing price) / 0.0001

Result in monetary value

When buying: (Closing price – opening price) x (closing quote/account currency) x (lot size x 100,000)
When selling: (Opening price – closing price) x (quote currency/account currency) x (lot size x 100,000)

View Example

Account currency = USD
Currency pair = GBP/CHF
Base = GBP, Quote = CHF
Quote/account currency = USD/CHF = 1.1025
Opening price = 2.1443
Closing price = 2.1452
Lot size = 0.01
Profit = (2.1452 – 2.1443) x 1.1025 x (0.01 x 100,000) = 0.99225USD

Our pip value calculator will help you to work out the value of a pip, which is important as part of your risk management strategy. To determine the pip value, select your account currency and currency pair, then add the opening and closing prices, the lot size and click calculate.

(Quote/account currency) x (lot size x 0.0001) x 100,000

(Quote/account currency) x (lot size x 0.01) x 100,000 (for JPY)

View Example

Account currency = USD
Currency pair = GBP/CHF
Opening price = 2.1443
Closing price = 2.1452
Quote/account currency = USD/CHF = 1.1025
Lot size = 2.57
Pip value = 1.1025 x (2.57 x 0.0001) x 100,000 = 28.3

Use our margin calculator to determine how much margin you require to guarantee a new open position. Your margin will help you to decide on your level of leverage and lot size. To work out the required margin, choose your account currency, currency pair, lot size and leverage and then click calculate.

((Base/account currency) x lot size x 100,000) / leverage

Account currency = USD
Currency pair = GBP/CHF
Base currency = GBP
Base/account currency = GBP/USD = 1.5819
Lot size = 0.01
Leverage = 1:200 Required margin = (1.5819 x 0.01 x 100,000) / 200 = 7.91USD
