What a pip actually is

A pip is the smallest standardised price move in a currency pair. For most pairs (EUR/USD, GBP/USD, AUD/USD and so on) a pip is the fourth decimal place — a move from 1.1050 to 1.1051 is one pip. For pairs quoted against the Japanese yen (USD/JPY, EUR/JPY) a pip is the second decimal place — a move from 150.20 to 150.21 is one pip, because yen values are quoted in whole units of currency rather than fractions. Some brokers also quote a fractional pip (the fifth decimal for most pairs, third for yen pairs), which is one-tenth of a standard pip.

Why knowing pip value matters

Pip value is the bridge between price action and money. When a chart shows EUR/USD moved 40 pips, that number means nothing to your account until you know what one pip is worth at your position size. A 40-pip move is a great trade on a standard lot (around $400 on most pairs) and a rounding error on a micro lot (around $4). Without pip value, stop-losses are guesses and risk management is vibes.

How the math works

The formula depends on which currency is quoted against which. For a pair where the quote currency is your account currency (e.g. you trade EUR/USD and your account is in USD), one pip on a standard lot of 100,000 units equals the pip size × lot size = 0.0001 × 100,000 = 10 units of quote currency, flat. For pairs where the quote currency is not your account currency, the formula divides by the quote-to-account exchange rate: pip value in account currency = (pip size × lot size) / exchange rate to account currency. For yen pairs, pip size is 0.01 instead of 0.0001, which is why yen pip values often look different from EUR/USD pip values even at the same lot size.

Lot sizes in plain terms

Standard lot: 100,000 units of the base currency. One pip is roughly $10 on most major pairs. Used by institutional traders and well-capitalised retail accounts.

Mini lot: 10,000 units. One pip is roughly $1. A reasonable starting size for retail traders learning to size positions.

Micro lot: 1,000 units. One pip is roughly $0.10. Common for smaller accounts and for strategy testing in live markets before scaling up.

Nano lot: 100 units. One pip is roughly $0.01. Available at some brokers for very small accounts or psychology-testing live fills.

Using pip value for position sizing

The practical application: you decide how much money you are willing to risk on a trade and where your stop-loss lives in pips. Pip value then tells you how big your position should be. Say you are willing to risk $100 on a trade, your stop is 25 pips away, and pip value at standard lot is $10. Then your position size is $100 / (25 × $10) = 0.4 standard lots (or 4 mini lots). This is the core of risk-of-ruin management — without pip-to-cash conversion, it is impossible to size consistently across pairs with different pip values.

Why pip value changes with exchange rate

A position's pip value drifts as the underlying exchange rate moves. On a GBP/USD long with a USD account, pip value is locked at $10 per standard lot because the profit is already denominated in dollars. But on a EUR/GBP long with the same USD account, pip value changes whenever GBP/USD moves, because profit in GBP has to be converted to USD at the current rate. The calculator uses the rate you enter, so for open positions, update the rate to see current-state pip value rather than entry-rate pip value. For position sizing before entry, use the current market rate.

What this calculator does not include

This tool returns pip value only. It does not calculate spreads, commissions, swaps, or slippage. Those costs are separate and can matter more than a single pip on short-term trades — on a 10-pip target with a 2-pip spread, you are handing back 20% of the target to the broker before you enter. When sizing positions, layer spread, commission, and expected slippage on top of the pip-value math, because the pip value alone overstates actual realised profit and loss.
