How to Calculate Lot Size for Apple (AAPL): Shares, Lot Size and Position Sizing
BY TIOmarkets
|March 21, 2026Apple is one of the most widely held and traded stocks in the world, and its CFD equivalent is a staple instrument for retail traders seeking exposure to large-cap US technology.
Before placing an AAPL trade, knowing how lot sizes map to share exposure, what each price movement is worth in dollar terms, and how much margin a given position requires gives you the information needed to size your trade deliberately and manage risk consistently.
This guide covers how AAPL contracts are structured at TIOmarkets, how to calculate point value per lot, how to work out required margin, and how to apply a position sizing formula.
How AAPL Lot Sizes Work
At TIOmarkets, one standard lot of AAPL represents 100 shares. The minimum lot size is 0.01 lots, which represents 1 share. Positions can be sized in increments of 0.01 lots, giving traders precise control over their share exposure from a single share at the minimum up to 2,000 shares at the maximum of 20 lots per trade.
In practical terms, a 0.10 lot position represents 10 shares, a 0.50 lot position represents 50 shares, and a 1.0 lot position represents the full 100 shares. Because AAPL is a stock CFD, you are not purchasing or taking ownership of Apple shares. You are entering a contract that tracks the Apple share price, allowing you to take both long and short positions with leverage. All profit, loss, and margin calculations are denominated in USD, since AAPL is priced in US dollars per share.
Point Value for AAPL
AAPL is quoted in USD per share to two decimal places, meaning the smallest price movement is USD 0.01. This is referred to as a point or tick rather than a pip, which is terminology specific to currency pairs.
The point value per lot is calculated as: point size x shares per lot.
For a standard lot (1.0): USD 0.01 x 100 shares = USD 1.00 per point. For a mini lot (0.10): USD 0.01 x 10 shares = USD 0.10 per point. For a micro lot (0.01): USD 0.01 x 1 share = USD 0.01 per point.
A USD 1.00 move in the Apple share price equals 100 points. On a standard lot of 100 shares, a USD 1.00 move equals USD 100 in profit or loss. On a 0.10 lot the same move equals USD 10, and on a 0.01 lot it equals USD 1.00.
Apple shares can move several dollars in a single session around earnings announcements, product launches, and macroeconomic data that affects the broader technology sector. Understanding the dollar value of each point move relative to your lot size before entering a position is a practical first step in risk management.
Calculating Required Margin for AAPL
AAPL carries a 5% margin requirement at TIOmarkets, corresponding to leverage of 1:20. Because the margin is a percentage of the notional value of the position, and the notional value is based on the current share price, the required margin changes as the Apple share price moves.
The formula is: required margin = lot size x shares per lot x current share price x margin percentage.
Using an illustrative Apple share price of USD 210 per share (this is an example only and not a current market quote):
For a standard lot (1.0): 1.0 x 100 x USD 210 x 0.05 = USD 1,050. For a mini lot (0.10): 0.10 x 100 x USD 210 x 0.05 = USD 105. For a micro lot (0.01): 0.01 x 100 x USD 210 x 0.05 = USD 10.50.
When Apple shares are trading at higher levels the margin required to open a position increases proportionally, and when shares are lower the margin requirement falls.

Leverage on AAPL is subject to change depending on market conditions and applicable regulatory requirements.
Position Sizing for AAPL
Position sizing is the process of calculating what lot size to use so that your potential loss, if your stop loss is triggered, stays within a defined limit relative to your account balance. The approach is to set a maximum risk percentage per trade, then work backwards to the appropriate lot size.
The formula is: lot size = account risk in USD / (stop loss in points x point value per standard lot).
Worked Example
Suppose you have a USD account with a balance of USD 5,000. You are willing to risk 1% per trade, which is USD 50. Your analysis of the AAPL chart suggests placing a stop loss USD 2.50 below your entry price, which represents 250 points.
Point value per standard lot: USD 1.00.
Lot size = USD 50 / (250 x USD 1.00) = USD 50 / USD 250 = 0.20 lots.
Trading 0.20 lots with a 250-point stop loss risks USD 50 if the stop is triggered, exactly matching the 1% risk limit. At USD 210 per share, a 0.20 lot position represents 20 shares with a notional value of USD 4,200 and a required margin of approximately USD 210.
If you tightened your stop to USD 1.00 (100 points), the same USD 50 risk budget would support a 0.50 lot position. If you widened your stop to USD 5.00 (500 points), you would need to reduce to 0.10 lots to remain within the same risk limit. The position sizing formula ensures your lot size always adjusts to your stop distance, keeping risk consistent regardless of market conditions.
Using TIOmarkets' Calculators for AAPL
TIOmarkets provides an online calculator suite at tiomarkets.com to help traders work through position sizing and cost estimates before placing a trade.
The margin calculator at tiomarkets.com/margin-calculator takes your instrument, account currency, leverage, and lot size as inputs and returns the required margin at current prices. For AAPL, entering your lot size gives you the exact margin figure at the current share price, which is more reliable than a manual calculation using an illustrative price.
The profit calculator at tiomarkets.com/profit-calculator allows you to model a trade by entering your open price, close price, lot size, and account currency, returning an estimated profit or loss. This is particularly useful for checking how a specific stop loss or take profit level translates into a USD figure before committing to the trade.
Spreads, Commissions and Overnight Financing
AAPL spreads at TIOmarkets are variable and fluctuate with market conditions. They can widen around market open and close, earnings announcements, and periods of elevated volatility. Minimum spread figures represent the lowest observed under favourable conditions and are typically higher in practice. On a Raw account, a commission of USD 6 per round turn lot applies, charged in full when the position is opened and covering both the open and close of the trade. On Standard and VIP Black accounts there is no commission, with costs reflected in the spread.
Positions held overnight on AAPL are subject to an overnight financing charge. Current financing rates should be checked inside the MT4 or MT5 platform before holding AAPL positions overnight.
Positions held at the ex-dividend date may receive a dividend adjustment, which can be positive or negative depending on the direction of your trade.
