Pip value math

How many dollars a 1-pip move is worth on your position — the core position-sizing input in FX.

What it means

Pip value is the dollar amount one pip of movement represents on a given position. For USD-quote majors (EUR/USD, GBP/USD, AUD/USD) one standard lot equals $10 per pip, constant regardless of price. For yen-quote pairs (USD/JPY, EUR/JPY) pip value in dollars varies with the exchange rate — at USD/JPY 150, one standard lot is ~$6.67 per pip. For cross-rate pairs (EUR/GBP, AUD/JPY) pip value depends on the quote currency's rate back to your account currency.

Why it matters

Every position-size decision in FX runs through pip value. If you don't know how many dollars per pip you're risking, you don't know how much you're risking — period. The single most common retail error is sizing 'by lots' instead of 'by dollars,' buying 'half a lot of EUR/JPY' without knowing pips on EUR/JPY are different sized than pips on EUR/USD.

How to use it

Pre-trade, fix your dollar risk first ($200 max loss). Derive pip risk from stop distance (40 pips). Then compute position size: dollar risk / pip risk = pip value needed ($5/pip → mini lot, $10/pip → standard lot). For yen and cross pairs, let the platform calculate live pip value in your account currency — but verify the order of magnitude makes sense.

Example

EUR/USD long at 1.0850 with a 30-pip stop. Pip value = $10/pip per standard lot. Max loss = $300 per standard lot. If max risk is $150, size = half a standard lot = 50,000 EUR (5 mini lots).

Deep dive

The three pair categories and their pip math

(1) Direct USD-quote (EUR/USD, GBP/USD, AUD/USD, NZD/USD): pip value = $10 per standard lot, constant regardless of price. (2) Reverse USD-quote (USD/JPY, USD/CHF, USD/CAD): pip value in dollars VARIES with the exchange rate because the foreign currency is the quote. USD/JPY at 150 = $6.67/pip per standard lot; USD/JPY at 110 = $9.09/pip. (3) Cross pairs (EUR/JPY, GBP/AUD): pip value depends on the quote currency's rate vs USD. Retail platforms display the live value in the order ticket — but knowing why it changes is the difference between professional and amateur sizing.

Pip vs pipette and what the 5th decimal actually does

Modern ECN platforms quote to 5 decimal places on majors (or 3 on yen pairs). That extra digit is a pipette — 1/10 of a pip. A spread of '0.6 pips' is technically 6 pipettes (0.00006 on EUR/USD). Pip value math is unchanged; pipettes just give finer granularity for spread quoting and entry precision. The risk to retail: confusing pip and pipette when reading a quote ('the spread is 6.0' — pips or pipettes?). Always verify with the broker's documentation.

Frequently asked

What's the pip value on a micro lot?

Micro lot = 1,000 units (1/100 of a standard lot). EUR/USD micro: $0.10 per pip. USD/JPY at 150: $0.067 per pip. Most retail accounts under $5,000 trade micro lots to keep drawdowns survivable while building experience.

Why is pip value different on yen pairs?

Yen pairs quote to 2 decimals (150.25) instead of 4, so a pip is 0.01 not 0.0001. Net dollar risk per pip ends up roughly comparable across pairs: 0.01 × 100,000 / 150 ≈ $6.67 on USD/JPY vs $10 on EUR/USD.

Do I need to calculate pip value manually?

No — every modern broker displays live pip value in the order ticket in your account currency. The point of understanding the math is to sanity-check the platform and to size correctly when comparing cross-pair positions in a multi-pair strategy.
