The whole formula
pip value = pip size × position size × (quote currency → account currency)
That is all of it. A standard lot of 100,000 units with a 0.0001 pip is 10 units of the quote currency per pip. If your account is denominated in that quote currency, the conversion is 1 and a pip is $10.
Three sizes cover almost everything: standard lot 100,000, mini 10,000, micro 1,000 — giving roughly $10, $1 and $0.10 per pip on a four-decimal pair.
The mistake this page is built around
The pip is not always 0.0001.
- JPY pairs quote to two or three decimals, so the pip is 0.01.
- Gold (XAUUSD) is usually quoted to two decimals, and most brokers treat 0.01 as the pip.
- Indices and many CFDs move in whole points, and "pip" stops meaning anything useful.
Using 0.0001 where the pip is 0.01 understates the value by a factor of a hundred. The error runs one way and it runs badly: a trader sizing a position to risk $200 ends up risking $20,000. That is why the calculator raises a warning when a 0.01 pip meets a full standard lot rather than quietly returning the number.
If you are unsure, do not guess — one trade at the wrong scale is more expensive than the minute it takes to check the contract specification with your broker.
Why the conversion rate is a field and not a lookup
Most pip calculators quietly assume your account is in USD. That is right often enough to be dangerous.
For a pair XXX/YYY, the pip value is naturally expressed in YYY, the second currency. If your account is in a third currency — a euro account trading GBPJPY, say — the value has to be converted, and that conversion moves with the market. We ask for the rate instead of fetching one because we do not ship a price feed, and a stale rate presented as live is worse than an honest field.
The practical consequence is small but real: on a cross-currency account the pip value drifts day to day even though the position has not changed.
What pip value is actually for
It is not a risk measure on its own. It is the bridge between the chart and the account: the chart gives a stop distance in pips, the pip value turns that distance into money, and money is what your risk percentage is written in.
Used in the other direction it becomes position sizing — decide the money first, divide by the stop distance and the pip value, and the size falls out. That is what the position size calculator does, and it is the order that keeps the stop on the chart instead of on the account balance.
