What pip value means (before you calculate it)
A pip value is the monetary amount you gain or lose for a one-pip move in a specific FX pair, for a given trade size.
A pip is a standardized price step used by many FX quotes. For most pairs quoted with five decimals (e.g., 1.00000), a pip is typically 0.00010 of the quoted price (the last decimal place changes by one “pip”). Some pairs may be quoted with two decimals; then a pip is commonly 0.01.
Because pip value is a money amount, you need two parts:
- how much the price moved (pip size), and
- how that price move converts into the currency you measure profit/loss in (account currency).
Core pip value mechanics for any cross (model + inputs)
To calculate pip value for an NZD cross, start from a simple model:
- Let the pair be Base/Quote = A/B.
- Let P be the pip size in price terms (for example, 0.00010 if the market is quoted with five decimals).
- Let the trade size be L lots.
- Let the contract size per lot be C units of the base currency (often 100,000, but you must use the provider’s contract specification for your account).
Step 1: Convert one pip into the quote-currency amount
For a base/quote pair A/B, a one-pip move changes the value of the position in a way that is usually expressed as:
- Value per pip (in quote currency) ≈ (C × P × L) ÷ CurrentPrice
This works when your pip is defined as a move in the quote price of the form “base price per quote unit” (the common FX quotation convention).
Step 2: Convert quote-currency pip value into account currency
Your account may not be denominated in the pair’s quote currency. If your account currency is different, convert the quote-currency pip value using an available FX conversion rate.
- Value per pip (in account currency) = (pip value in quote currency) × (FX rate needed to convert quote → account)
This is where NZD crosses often differ in practice: you may need one or two conversion rates depending on which currency your account uses and which currency appears as the quote in the NZD pair you are trading.
Worked example: NZD cross pip value in different account currencies
Assumptions for this example (you can substitute your own values):
- Pair: NZD/USD (NZD is base, USD is quote)
- Pip size: P = 0.00010
- One lot: C = 100,000 NZD units
- Trade size: L = 1 lot
- Current price: CurrentPrice = 0.65000 USD per NZD
- Account currency cases: USD vs NZD
Case A: Account currency = USD (same as quote currency)
- Quote-currency pip value:
- pip value (USD) ≈ (100,000 × 0.00010 × 1) ÷ 0.65000
- pip value (USD) ≈ 10 ÷ 0.65000 ≈ 15.38 USD per pip
No extra conversion is needed because the quote currency already matches the account currency.
Case B: Account currency = NZD (account currency is base currency)
You now convert the USD pip value back into NZD. Since the account currency is NZD, the conversion uses an FX rate for USD → NZD. If NZD/USD = 0.65000, then USD/NZD = 1 ÷ 0.65000.
- pip value (NZD) = pip value (USD) × (USD → NZD rate)
- pip value (NZD) ≈ 15.38 × (1 ÷ 0.65000) ≈ 23.66 NZD per pip
Key idea: the numeric pip value changes with account currency even for the same one-pip move.
Why “pip value for NZD crosses” can be different from “pip value for major pairs”
An NZD cross typically means a pair that involves NZD but is not necessarily quoted against a “home” currency like USD. The core calculation is the same, but the conversion step becomes more complex:
- If your pair’s quote currency is not your account currency, you must convert.
- Conversions may require using a related FX quote as a proxy (for example, using the inverse rate if the needed direction is reversed).
Also, provider contract details matter. Some platforms define lot size or contract units differently for specific instruments. Using a wrong contract size C is a common source of mistakes.
