What is a Pip in Forex? Pip Value Math Explained
A pip ("percentage in point") is the smallest standardized price move in forex. On most pairs (EURUSD, GBPUSD) it's 0.0001 (the 4th decimal). On JPY pairs (USDJPY, EURJPY) it's 0.01 (the 2nd decimal). On gold (XAUUSD) it's typically 0.10. The pip VALUE — what one pip is worth in dollars — depends on lot size and the quote currency: 1 standard lot of EURUSD = $10/pip; 1 mini lot = $1/pip; 1 micro lot = $0.10/pip. A "pipette" is 1/10th of a pip, the 5th decimal — used by brokers for finer pricing precision.
Why a pip is 0.0001 on most pairs but 0.01 on JPY
Forex prices reflect the relative value of one currency against another. Most pairs trade at values around 1.0 (EURUSD = 1.10, GBPUSD = 1.27, AUDUSD = 0.66). A 4th-decimal move (0.0001) is roughly 0.01% of the price — small enough to be a meaningful unit but large enough to actually appear in market data.
JPY pairs are different because the yen has 100x lower per-unit value than the dollar (USDJPY = 150, not 1.50). The same 0.01% move at JPY's price level is 0.015 — too granular. The convention is to express JPY pip moves at the 2nd decimal (0.01), which keeps the practical "1 pip ≈ small but measurable move" feeling consistent.
Gold (XAUUSD) trades at thousands ($2,400+). Pip conventions vary by broker — most use 0.10 as 1 pip, some use 0.01 (10 pipettes per pip). Always check broker contract specs.
How to calculate pip value (the formula)
Pip value formula:
(pip size × lot size in units) / current exchange rate (if quote currency ≠ USD)
EURUSD example: - Pip size: 0.0001 - Lot size: 100,000 units (1 standard lot) - Quote currency = USD, so no conversion - Pip value = 0.0001 × 100,000 = $10/pip
USDJPY example: - Pip size: 0.01 - Lot size: 100,000 USD - Quote currency = JPY at 150 - Raw value: 0.01 × 100,000 = ¥1,000 - Convert to USD: ¥1,000 / 150 = $6.67/pip
This is why USDJPY pip value is ~$6-9 (not $10 like EURUSD) — JPY is the quote currency, so you have to convert back to your account currency.
Pipettes — the 5th decimal
Modern broker pricing has a 5th decimal on most pairs (EURUSD = 1.08543) and a 3rd decimal on JPY pairs (USDJPY = 150.234). This 5th/3rd decimal is called a "pipette" or "fractional pip" and equals 1/10th of a pip.
Why pipettes exist: in the old days (pre-2010) brokers quoted to 4 decimals only and competed mostly on spread width. Pipettes let brokers compete on tiny pricing differences — "0.6 pip spread vs 0.7 pip spread" matters more when you can quote 0.65 vs 0.74.
For traders, pipettes don't change the math. A "5-pip stop loss" still means 5 full pips (50 pipettes). Just be careful when copying spreads from broker comparison tables — "0.0 pip" usually means 0.0 pip + spreads sometimes including pipettes.
Frequently asked
Why is pip value different on different pairs?
Because pip value depends on the quote currency. EURUSD's quote is USD (1 pip = $10/lot). USDJPY's quote is JPY, so you must convert ¥1000 back to USD using the current rate.
How many pips should my stop loss be?
Depends on volatility and timeframe. Day traders on EURUSD typically use 15-30 pip stops. Swing traders use 50-150 pips. Position size = (account × risk%) / (stop pips × pip value). Use the calculator.
Are pip values the same in all account currencies?
No. If your account is in EUR but you trade EURUSD, pip value depends on the EURUSD rate at calculation time. Most modern broker platforms show pip value in your account currency in real-time.
