FX Calculator for Pips, Lot Size, Margin and Profit/Loss
Enter the currency pair, lots, leverage, direction, entry rate and exit rate to get the profit or loss in pips and yen, the value of one pip and the required margin. Yen pairs such as USD/JPY work as they are; for other pairs such as EUR/USD, type in the yen rate of the quote currency so the result can be converted into yen. All rates are typed by hand and no live feed is used. To project how savings grow over time, try the Investment Growth Simulator.

This tool is a calculation aid, not investment advice or a trade recommendation. Spread, swap points, commissions and stop-out are not included. Real profit and margin depend on your broker's execution and margin rules.
Trade settings
Individual accounts in Japan are capped at 25x. Other countries differ.
Notes
- Spread, swap points, commissions and stop-out are not included, so real results will differ by those amounts.
- One pip is 0.01 for yen pairs and 0.0001 for the others. Pips are handled down to 0.1 pip (a tenth of a pip).
- Required margin is units x entry rate / leverage, converted into yen and rounded up to a whole yen. Some brokers use a different reference rate for margin.
- For non-yen pairs, the single quote-currency/JPY rate you enter is used to convert both profit and margin. Real fills use different rates at entry and exit, so treat the result as an estimate.
- Profit in yen is rounded to the nearest yen. Rates are typed by hand; no live market data is fetched.
Glossary
Pip
The unit of an exchange-rate move. One pip is 0.01 for yen pairs and 0.0001 for pairs like EUR/USD.
Lot
The unit of position size. One lot is 100,000 units at many brokers; some use 10,000 or 1,000.
Leverage
The multiple of your margin you can trade. At 25x you need a margin of 4% of the position value.
Required margin
The collateral you must hold in the account to open a position. It is the position value divided by leverage.
Quote currency
The currency on the right side of a pair. For USD/JPY it is JPY, and the exchange rate is expressed in it.
FAQ
How much is one pip worth?
For yen pairs one pip is 0.01 yen per unit, so 100,000 units is 1,000 yen and 10,000 units is 100 yen. For other pairs, multiply 0.0001 by the units to get the value in the quote currency, then convert it with that currency's yen rate. For 10,000 units of EUR/USD with USD/JPY at 150, one pip is 1 USD, about 150 yen.
How is required margin calculated?
Multiply the units by the entry rate to get the position value, convert it into yen and divide by the leverage. Buying 100,000 USD/JPY at 150 with 25x leverage is a 15 million yen position, so the margin is 4% of that, 600,000 yen. Brokers may use a different reference rate, so the real figure can differ a little.
How is profit on a non-yen pair converted to yen?
The profit is first found in the quote currency and then multiplied by the quote/JPY rate you enter. For EUR/USD, enter the USD/JPY rate. Brokers usually convert at the rate when you close, so the result is an estimate to the extent your input differs from it.
How are pips signed for a short trade?
A sell trade profits when the exit rate is below the entry rate. Entry at 150.00 and exit at 149.50 is +50 pips, while an exit at 150.50 is -50 pips. A buy trade is the opposite.
Are spread and swap included?
No. This tool uses only the difference between the two rates. In real trading the spread makes your fill worse, and swap points and commissions are added depending on the holding period, so actual results differ by those amounts.
