In forex, a lot is the unit used to measure trade size, and a pip is the standard unit for measuring price changes. A standard lot is 100,000 units of the base currency, a mini lot is 10,000 and a micro lot is 1,000. For most pairs, a pip is the fourth decimal place (0.0001); for Japanese yen pairs, it is the second (0.01). Pip value, the amount one pip is worth, equals the pip size multiplied by the number of units traded, converted into the account currency. For EUR/USD, one pip on a standard lot is worth $10.

Key takeaways

• Standard lot = 100,000 units, mini lot = 10,000 units, micro lot = 1,000 units of the base currency.
• A pip is 0.0001 for most pairs and 0.01 for JPY pairs; a pipette is one tenth of a pip.
• Pip value = pip size × units traded, expressed first in the quote currency and then converted into the account currency.
• Pip value, not leverage, determines how much a position gains or loses for each pip the price moves.

What Is a Lot in Forex?

A lot is the standard unit of trade size in forex. Rather than typing an amount of currency, traders on platforms such as MetaTrader 4 and MetaTrader 5 enter a volume in lots.

Lot type	Volume in platform	Units of base currency	Pip value on EUR/USD
Standard lot	1.00	100,000	$10.00
Mini lot	0.10	10,000	$1.00
Micro lot	0.01	1,000	$0.10

Volumes can usually be set in steps of 0.01 lot, so a trade of 0.25 lots equals 25,000 units. CMS Prime lists a minimum trade size of 0.01 lot for its Core, Master and Signature accounts on its account comparison page.

The base currency is the first currency in a pair. In EUR/USD, one standard lot means buying or selling 100,000 euros. In USD/JPY, it means 100,000 US dollars.

What Is a Pip?

A pip (short for “percentage in point” or “price interest point”) is the conventional unit for measuring price changes in a currency pair.

• For most pairs, one pip is 0.0001, the fourth decimal place. If EUR/USD moves from 1.1000 to 1.1025, it has moved 25 pips.
• For pairs quoted in Japanese yen, one pip is 0.01, the second decimal place. If USD/JPY moves from 150.00 to 150.40, it has moved 40 pips.

Most platforms quote prices with one extra decimal place. That extra digit is a pipette, or fractional pip, equal to one tenth of a pip. On a five-digit EUR/USD quote of 1.10253, the final 3 is pipettes.

On MetaTrader, the contract specification often lists sizes in points, which usually correspond to the smallest price increment, the pipette. A spread shown as “12 points” on EUR/USD is therefore 1.2 pips. Terms such as pip, point and spread are defined in CMS Prime’s glossary.

The Pip Value Formula

Pip value tells you how much one pip of movement is worth for a given position size.

Pip value (in quote currency) = Pip size × Units traded

Because the result is in the quote currency, the second currency in the pair, it may need converting into the account currency:

• If the quote currency is the same as the account currency, no conversion is needed.
• If not, the value is converted using the current exchange rate between the quote currency and the account currency.

Worked Examples (USD Account)

Example 1: EUR/USD, 1 standard lot

Pip value = 0.0001 × 100,000 = $10. The quote currency is USD, so no conversion is needed. A 30-pip move equals $300 on one standard lot.

Example 2: USD/JPY, 1 standard lot at 150.00

Pip value = 0.01 × 100,000 = ¥1,000. Converted to USD: ¥1,000 ÷ 150.00 = about $6.67. Because the quote currency is JPY, the dollar value of a pip changes as the USD/JPY rate changes.

Example 3: EUR/GBP, 1 standard lot, with GBP/USD at 1.3000

Pip value = 0.0001 × 100,000 = £10. Converted to USD: £10 × 1.3000 = $13.00.

Example 4: USD/CHF, 0.50 lots at 0.9000

Pip value = 0.0001 × 50,000 = CHF 5. Converted to USD: CHF 5 ÷ 0.9000 = about $5.56.

Pair	Position	Pip value in quote currency	Approximate pip value in USD
EUR/USD	1.00 lot	$10	$10.00
GBP/USD	0.10 lot	$1	$1.00
USD/JPY at 150.00	1.00 lot	¥1,000	$6.67
EUR/GBP (GBP/USD 1.3000)	1.00 lot	£10	$13.00
USD/CHF at 0.9000	0.50 lot	CHF 5	$5.56

Pip Value for UAE Traders: Converting to AED

Many trading accounts are held in US dollars, while day-to-day expenses in the UAE are in dirhams. Because the UAE dirham is pegged to the US dollar at about 3.6725, with the Central Bank of the UAE intervening at 3.672 and 3.673, converting a USD pip value to AED is straightforward:

• $10 per pip ≈ AED 36.73 per pip
• $1 per pip ≈ AED 3.67 per pip
• $0.10 per pip ≈ AED 0.37 per pip

This conversion is useful for understanding exposure in local terms. It does not change how the account itself is calculated.

Lot Size and Pip Value for Gold and Other Instruments

The same principles apply to non-forex instruments, but contract sizes and tick sizes differ.

• Gold (XAU/USD): one lot is commonly 100 troy ounces. A $1.00 move in the gold price is then worth $100 per lot. Some brokers describe a $0.10 move as one pip, others use $0.01, so terminology varies.
• Indices and oil CFDs: contract sizes vary by broker and instrument.

Contract size, tick size and tick value for every symbol are listed in its specification on MT4 and MT5, found by right-clicking the symbol in Market Watch and choosing Specification. CMS Prime’s commodities trading page lists the metals and energy products it offers.

How Lot Size Connects to Risk

Pip value links position size to potential gains and losses. Two traders who see the same 40-pip move on EUR/USD can have very different outcomes:

Position size	Pip value	40-pip move
0.01 lot	$0.10	$4
0.10 lot	$1.00	$40
0.50 lot	$5.00	$200
1.00 lot	$10.00	$400
2.00 lots	$20.00	$800

This is why position sizing starts with pip value. A common approach is to decide the maximum amount at risk on a trade, measure the distance to the stop-loss in pips and then work out the lot size:

Lot size = Amount at risk ÷ (Stop distance in pips × Pip value per lot)

For example, with $100 at risk and a 40-pip stop on EUR/USD: $100 ÷ (40 × $10) = 0.25 lots.

Leverage affects how much margin a position needs, but it does not change the pip value. A 1-lot EUR/USD position moves $10 per pip whether the account uses 1:30 or 1:500 leverage. CMS Prime’s trading need-to-knows introduces how leverage and margin work.

Common Mistakes With Lot Size and Pip Value

• Confusing pips and points. A 20-point stop on a five-digit quote is 2 pips, not 20.
• Assuming every pair is $10 per pip. Only pairs quoted in USD have a fixed $10 pip value per standard lot on a USD account.
• Ignoring the JPY decimal. On yen pairs, a pip is 0.01, not 0.0001.
• Forgetting conversion. Cross pairs such as EUR/GBP or AUD/NZD need a conversion into the account currency.
• Using the same lot size on every instrument. Gold, indices and oil have different contract sizes and move by different amounts each day.

Frequently Asked Questions

How much is one pip worth in forex? It depends on the pair and the position size. For pairs quoted in US dollars, such as EUR/USD or GBP/USD, one pip is worth $10 on a standard lot, $1 on a mini lot and $0.10 on a micro lot. For other pairs, the value is converted from the quote currency into the account currency.

What is the difference between a standard, mini and micro lot? A standard lot is 100,000 units of the base currency, a mini lot is 10,000 units and a micro lot is 1,000 units. On MetaTrader, these appear as volumes of 1.00, 0.10 and 0.01 lots respectively.

Why are JPY pairs different? Japanese yen pairs are quoted to two decimal places rather than four, because of the yen’s lower value per unit. One pip on a yen pair is therefore 0.01 rather than 0.0001, and the pip value in USD changes with the exchange rate.

What is a pipette? A pipette is one tenth of a pip, shown as the fifth decimal on most pairs and the third decimal on yen pairs. Platforms with five-digit pricing quote in pipettes, which MetaTrader often labels as points.

Does leverage change pip value? No. Leverage changes the margin required to open a position, not the value of each pip. Pip value depends only on the position size, the pair and the exchange rate used for conversion.

How do I find pip value for gold or indices? Open the symbol’s specification on MT4 or MT5 to see the contract size and tick value. For gold, one lot is commonly 100 ounces, so a $1 price move equals $100 per lot, but terms vary between brokers.

Conclusion

Forex lot size and pip value are the two numbers that turn price movements into account results. Lots measure how much is traded, from micro lots of 1,000 units to standard lots of 100,000, while pips measure how far price moves. Multiplying pip size by the number of units gives pip value in the quote currency, which is then converted into the account currency. Understanding this calculation makes position size, stop distances and risk easier to compare across pairs. CMS Prime’s MT4 and MT5 platforms display contract specifications and pip-based results for every symbol.
