How to Calculate Pip Value in Forex
If you can't calculate what a pip is worth, you can't size your positions properly. Without proper position sizing, risk management doesn't exist — you're just guessing. This guide walks through the actual maths, not theory.
What Is a Pip?
A pip (percentage in point) is the smallest standard unit of price movement in a currency pair. For most pairs, it's the fourth decimal place:
- EUR/USD moves from 1.0850 to 1.0851 → that's 1 pip
- EUR/USD moves from 1.0850 to 1.0950 → that's 100 pips
Most brokers quote five decimal places (1.08501). That fifth digit is a pipette — one-tenth of a pip. So 1.08501 to 1.08516 is 1.5 pips.
JPY Pairs Are Different
Japanese yen pairs use two decimal places. One pip on USD/JPY is 0.01, not 0.0001.
USD/JPY moves from 150.50 to 150.75 → that's 25 pips, not 2,500. This trips up a lot of beginners — entering a 50-pip stop loss as 0.0050 instead of 0.50 puts you off by a factor of 100.
The Formula
Pip Value = (One Pip ÷ Exchange Rate) × Lot Size
Where one pip = 0.0001 for most pairs, 0.01 for JPY pairs.
That's it. Everything else is just plugging in numbers.
Worked Examples
EUR/USD — USD as Quote Currency
When USD is the quote currency, pip values come out directly in dollars.
- Pair: EUR/USD at 1.0850
- Size: 1 standard lot (100,000 units)
(0.0001 ÷ 1.0850) × 100,000 = $9.22 per pip
In practice, any pair ending in USD gives you roughly $10 per pip on a standard lot. The exact figure shifts with the exchange rate, but $10 is close enough for quick mental maths.
USD/CHF — USD as Base Currency
When USD is the base currency, the pip value comes out in the quote currency first.
- Pair: USD/CHF at 0.8800
- Size: 1 standard lot
(0.0001 ÷ 0.8800) × 100,000 = CHF 11.36 per pip
To get dollars: CHF 11.36 ÷ 0.8800 = $12.91 per pip
USD/JPY — Yen Pair
Remember: pip size is 0.01 here.
- Pair: USD/JPY at 150.50
- Size: 1 standard lot
(0.01 ÷ 150.50) × 100,000 = ¥6.64 per pip → about $6.64
That's noticeably lower than the ~$10 on EUR/USD. Same lot size, different risk.
EUR/GBP — Cross Pair
No USD in the pair, so you need an extra conversion step.
- Pair: EUR/GBP at 0.8550, GBP/USD at 1.2650
- Size: 1 mini lot (10,000 units)
(0.0001 ÷ 0.8550) × 10,000 = GBP 1.17 per pip
GBP 1.17 × 1.2650 = $1.48 per pip
Lot Sizes and Pip Values
For pairs ending in USD (EUR/USD, GBP/USD, AUD/USD), pip values scale linearly with lot size:
| Lot Type | Units | Pip Value (approx.) |
|---|---|---|
| Standard | 100,000 | $10 |
| Mini | 10,000 | $1 |
| Micro | 1,000 | $0.10 |
| Nano | 100 | $0.01 |
Half a standard lot → $5 per pip. Three mini lots → $3 per pip. The relationship is always proportional.
For non-USD pairs, these base values shift with the exchange rate, but the proportional relationship between lot sizes holds.
Quick Reference: Pip Values at 1 Standard Lot
These are approximate and fluctuate with exchange rates:
| Pair | Pip Size | Pip Value (USD) |
|---|---|---|
| EUR/USD | 0.0001 | ~$10 |
| GBP/USD | 0.0001 | ~$10 |
| AUD/USD | 0.0001 | ~$10 |
| USD/JPY | 0.01 | $6.50–7.00 |
| USD/CHF | 0.0001 | $11–13 |
| USD/CAD | 0.0001 | $7–8 |
| EUR/GBP | 0.0001 | $12–13 |
Why This Matters: Position Sizing
Knowing pip values lets you calculate position size from your risk tolerance:
Position Size = Risk Amount ÷ (Stop Loss in Pips × Pip Value per Lot)
Example: You have a $5,000 account. You want to risk 1% ($50) on a EUR/USD trade with a 40-pip stop loss.
$50 ÷ (40 × $1 per mini lot) = 1.25 mini lots
Without this calculation, you're either risking too much or too little on every trade. This ties directly into understanding leverage — higher leverage doesn't change pip value, but it changes how much margin you need to hold the position.
Three Mistakes to Avoid
Using the same lot size for every trade. A 20-pip stop and a 100-pip stop at 1 mini lot means $20 risk on one trade and $100 on the next. That's a 5× difference for no reason.
Ignoring pip value differences between pairs. 1 standard lot on EUR/USD ($10/pip) vs 1 standard lot on USD/JPY ($6.64/pip) is different risk despite identical lot sizes. This is also why understanding what the spread is matters — a 2-pip spread costs you more on a pair with a higher pip value.
Forgetting to convert to your account currency. If your account is in ZAR, a $10 pip value converts at the current USD/ZAR rate. At 18.50, that's R185 per pip — which changes your risk calculation significantly. Understanding pip values also feeds directly into calculating margin requirements for your positions.
Use a Pip Calculator
You don't need to do this by hand on every trade. The ComoFX pip calculator takes your pair, lot size, and account currency, and returns the pip value instantly.
That said — understand the maths behind it. Calculators can break, and you should be able to spot when a number looks wrong.
