Direct answer
Pip value is the amount of profit or loss in account currency caused by a one-pip move in a currency pair’s quoted price. For GBP/EUR, you start from the pair’s pip size (the minimum quoted price increment), convert that price change into a base-currency cash amount (for the trade’s position size), and then convert into the account currency if needed.
Mechanics: what “pip value” means
A pip is a standardized price increment used in FX quotes. The exact pip size depends on the instrument specification, but for many major pairs quoted to five decimals, a common convention is:
- 1 pip = 0.0001 in the pair’s quote currency terms.
For GBP/EUR, the quote is typically read as: 1 GBP buys X EUR. So the quoted price is in EUR per GBP.
Step 1 — define your pip size (ΔP)
Assume the instrument uses the common convention:
- ΔP = 0.0001 EUR per 1 GBP for a one-pip move.
Important: some platforms or instruments may use different decimal pricing or pip definitions. Always use the pip size defined by your contract specification (not a generic rule).
Step 2 — translate a pip price move into cash (base position)
Let:
- N = position size in GBP (number of GBP units),
- ΔP = pip price move in EUR per GBP.
Then the cash move in EUR from one pip is:
- Pip value (in EUR) = N × ΔP.
If your platform reports pip value per “standard lot” or “mini lot,” it already encodes N through its contract size definition. If you are computing it from scratch, you must use the same unit your execution uses.
Step 3 — convert to the account currency
If your account currency is EUR, you are done: the pip value in EUR is the cash value.
If your account currency is not EUR, you convert the EUR result into the account currency using the relevant FX rate at the time you do the calculation (the rate you use for conversion must match your platform’s quoting convention).
A general conversion structure is:
- Pip value (in account currency) = Pip value (in EUR) × (EUR→Account FX rate), provided that the conversion rate is quoted in the direction that turns EUR into your account currency.
Evidence or example: GBP/EUR with different account currencies
Example assumptions
Use these explicit assumptions to make the calculation checkable:
- Pair: GBP/EUR
- Pip size: 1 pip = 0.0001 (ΔP = 0.0001)
- Position size: N = 10,000 GBP
- No spreads or fees included (pip value is about price movement only)
Pip value when the account currency is EUR
1 pip moves the quoted price by ΔP = 0.0001 EUR per GBP.
- Pip value (EUR) = N × ΔP = 10,000 × 0.0001 = 1.00 EUR So, one pip corresponds to 1 EUR for this assumed position size.
Pip value when the account currency is GBP
Now convert the EUR pip value into GBP. Using an FX conversion rate (EUR→GBP):
- Pip value (GBP) = 1.00 EUR × (EUR→GBP rate) If you instead have GBP/EUR, you can derive EUR→GBP as the reciprocal of the GBP/EUR price, but you must be consistent with how your platform quotes and calculates conversions.
Pip value when the account currency is USD (illustrative structure)
A typical two-step path is required because the pip value is naturally in EUR:
- Pip value (USD) = Pip value (EUR) × (EUR→USD rate) Some calculators do this directly if they provide an internal conversion using an agreed route; others require you to compute it.
Limitations and risks: where calculations commonly go wrong
- Pip size mismatch: Different instruments can use different decimal places or pip definitions. If your ΔP is wrong, pip value is wrong. 2. Contract sizing mismatch: Pip value depends on the exact position unit (e. g. , “per standard lot” vs “per unit”). If N does not match your contract size, results won’t align with your platform. 3. Conversion direction errors: Converting EUR pip value into an account currency requires careful handling of whether a quoted FX rate means “X account currency per 1 EUR” or the reverse. 4. Market and execution effects not included: Pip value is based on a price move of one pip.
