The answer

The direct answer: what 0.01, 0.1 and 1.0 lots mean

Here is the answer first. In forex, one standard lot as 100,000 base-currency units is a widely used convention, and on that basis 0.1 lot = 10,000 units (a mini lot) and 0.01 lot = 1,000 units (a micro lot). For example, 0.01 lot of USDJPY is 1,000 US dollars, and 0.1 lot of EURUSD is 10,000 euros of trade size. The way to get there is simple: units = contract size × lots.

That figure of 100,000, however, is not a fixed rule shared across the whole market. The contract size for one lot can differ by account type and instrument, and on CFDs in particular (gold, stock indices, crypto and so on) the forex idea of currency units does not carry over at all. So the final reference is always your trading account’s contract specification (contract size). In this article we first build the whole picture with the forex convention, then set out the exceptions and how to verify them.

This piece is the terms-and-conversion lesson of the lot-sizing cluster. The complete procedure for working position size back from a loss budget lives in the forex lot size formula guide, and the map of the whole cluster is the parent FX and CFD lot size calculation guide. Every number and figure shown here is fictional educational data, not a recommendation for any instrument or a suggestion of future profit or loss.

Terminology

Lot, units, contract size and order quantity

Most of the confusion comes from using similar words as if they meant the same thing. Start by separating four of them.

• Lot: the unit for counting trade size, specified as 0.01, 0.1, 1.0 and so on. On its own it is a multiplier of quantity, not an amount of currency.
• Contract size: the instrument specification that defines how many units one lot represents. For forex currency pairs it is conventionally 100,000 units.
• Units: the actual trade quantity, found with contract size × lots. So 0.1 lot × 100,000 = 10,000 units.
• Order quantity (volume): the figure you type into the trade ticket. Most platforms use lot notation, though some accounts let you enter units directly.

In other words, the same “0.1 lot” gives different units when the contract size differs. For a forex pair it is 10,000 units, but for an instrument whose contract size is 10,000 it would be 1,000 units. The word “lot” alone fixes neither the amount nor the risk, and that idea is the foundation of the whole article. The flow from a lot to an actual risk amount and required margin is covered in detail in the required margin and effective leverage guide.

Unit conversion

The 0.01 to 0.1 to 1.0 staircase: how units grow

When the lot grows tenfold, the units grow tenfold too. The figure below shows the three steps — micro, mini and standard — as a staircase, assuming a forex currency pair with a contract size of 100,000 (you can scroll it horizontally).

So the apparent smallness of a lot and its actual trade size need to be kept separate. Even if 0.01 lot “feels small,” on an instrument with a large contract size both the units and the implied gain or loss can be far from negligible. That is exactly why the next step is to check, with units attached, “how much one pip is worth.”

Smallest move

Pip, point, tick and the minimum price increment

Before computing 1-pip value, separate the units used to count price movement. Confuse them and you will be off by a digit.

• Pip: the conventional smallest move in foreign exchange. On most non-JPY pairs it is the fourth decimal place (0.0001), and on JPY pairs the second decimal place (0.01).
• Point: the smallest increment the broker actually displays. With fractional-pip pricing, one extra digit is called one point, and it is common to see 1 pip = 10 points. On some CFDs a point is defined as a 1.0 price move.
• Tick: the smallest unit a price actually moves in (tick size) and the money value of one such move (tick value). These are defined as instrument specifications and do not always coincide with a pip.

The distinction to hold on to is that a pip is a “foreign-exchange convention,” while a point and a tick are “broker and instrument specifications.” Even the idea that one pip on a JPY pair is 0.01 is a convention; if the broker quotes one extra digit (for example 0.001), the smallest step on screen is a point, not a pip. Always confirm how digits are counted against the price display and the tick size. The concrete workflow of measuring a stop distance in pips and turning it into a lot is covered in the forex lot size formula guide.

The formula

The 1-pip value formula: keep the units visible

The value of one pip is found with the formula below. The key is not to drop the units along the way.

This formula works both when you want the value from pips and, in reverse, when you are asking “which lot makes one pip worth a chosen amount.” It excludes spread, commission, swap and fill slippage, so the real result can be worse than this estimate.

Comparison

Comparing 0.01, 0.1 and 1.0 lots on USDJPY and EURUSD

Feeding the same formula with a fictional rate set (USDJPY = 150.00, EURUSD = 1.1000, USD to JPY = 150.00), the table lists units and 1-pip value with the account currency set to JPY. All of it is fictional educational data, not live prices.

On USDJPY the profit currency is JPY, so the profit-currency figure is already the JPY figure. On EURUSD the profit currency is USD, so the column with the USD-to-JPY conversion (for example 150.00) applied is the estimate that actually moves your account. The table also makes the proportional relationship visible: a tenfold increase in lots means a tenfold increase in value. Real figures shift with spread and fill price, so treat these as estimates.

Beyond forex

One lot of gold, indices and crypto CFDs is not 100,000 units

This is where people trip up most. Do not apply forex’s “one lot = 100,000 units” to XAUUSD (gold) or to index and crypto CFDs. These are not currencies; they trade in ounces, index points, coins and other units, and both the contract size and the definition of one pip or one point are entirely different. The table below is one fictional educational example of that difference (it varies widely by broker).

As you can see, when the instrument type changes, the meaning of “one lot” itself changes. Concrete examples for gold appear in the XAUUSD gold lot size guide, and the contract size and point value for index and crypto CFDs are covered, with worked numbers, in the CFD position sizing guide. For now, remember just one thing: do not carry the forex sense of currency units into these markets.

Verify the spec

Where to verify the contract specification: six fields to check

In the end, accurate calculation needs your own account’s instrument specification, not a convention. In MT4 or MT5 you can right-click the symbol and open its Specification. The card below lists the fields to check as a screen mock-up (fictional; not a reproduction of any real UI).

An illustrative display. The actual values and field names differ by broker and symbol. These numbers are educational and are not any specific broker’s specification.

With these six fields in hand, you can uniquely compute units, 1-pip (or 1-point) value, minimum lot and volume step. In particular, minimum volume and volume step are what you need to round a calculated lot down to a size you can actually place. If rounding down to the step falls below the minimum lot, that size may not be tradable. As a rule, round toward less risk, down to the nearest volume step.

Check it

Check units and 1-pip value with the conversion worksheet

The learning aid below takes contract size, lots, pip size and the conversion rate (profit currency to account currency), and shows units and 1-pip value with the formula attached. It is a simplified version meant to support the article, and it excludes spread, commission, swap, slippage and required margin. All calculation runs in your browser, and inputs are neither sent externally nor stored.

First, so it is readable even when JavaScript does not run, here is a static fictional educational worked example using the same defaults.

Once the worksheet has given you the feel, it is best to settle the values you will actually trade with in the free calculator. Checking units, 1-pip value, required margin and effective leverage for a single position is available on the free tier. When you reach the point of wanting to see aggregate risk across multiple positions, currency concentration and correlation, moving on to the aggregate multi-position risk guide and Pro features follows naturally.

Pitfalls

Common misunderstandings and how to avoid them

Mixing up lot, units and pip tends to collapse into a set of recurring patterns. If any sound familiar, open the contract specification and confirm on the spot.

• Applying “one lot = 100,000 units” to every instrument: gold, index and crypto CFDs use a different contract size. Do not think in currency units.
• Confusing pip and point: with fractional-pip pricing, 1 pip = 10 points. This is a classic source of being off by a digit.
• Using the same pip place for JPY and non-JPY pairs: swapping 0.01 and 0.0001 throws the value off by a factor of 100.
• Reversing the conversion-rate direction: multiplying without checking the profit-currency-to-account-currency direction shifts the magnitude.
• Ignoring minimum lot and volume step: a calculated value is not always placeable as is. Round down to the step.
• Treating the value as final without spread and costs: worksheet figures are estimates, and real fills can be worse.

Practical check

Pre-order checklist

When lot notation confuses you, checking in the following order prevents order-of-magnitude errors. None of these are trading decisions; they are steps for grasping quantity.

• Did you confirm the traded instrument’s contract size in the specification?
• Did you grasp the actual trade quantity with units = contract size × lots?
• Did you confirm that instrument’s pip or point definition and digit place (tick size)?
• Did you compute 1-pip value = contract size × pip size × lots × conversion rate, with units attached?
• When the profit currency and account currency differ, is the conversion-rate direction correct?
• Did you round to the minimum volume and volume step?
• For non-forex, are you avoiding carrying the forex 100,000-unit rule across?

Summary

Summary: the answer and your next step

In forex, on the convention of a 100,000-unit contract size, 0.01, 0.1 and 1.0 lots are 1,000, 10,000 and 100,000 units. But the deciding factor is the formula units = contract size × lots, not the figure 100,000 itself. Change the contract size and both the units and the 1-pip value change, and on gold, index and crypto CFDs the forex sense of currency units simply does not apply.

Compute 1-pip value with contract size × pip size × lots × conversion rate, keeping the units in place. Distinguish pip, point and tick, and do not swap the digit places of JPY and non-JPY pairs. Finally, always back it up with your account’s contract specification (contract size, tick, minimum volume, volume step, profit currency) — that is the heart of this article.
