For many UK and Ireland-based clients, spread betting is often compared with CFDs because both products provide leveraged exposure to markets such as indices, forex, shares, commodities and ETFs. Both can be used to speculate on rising and falling prices, and both involve a high level of risk because leverage can magnify losses as well as profits.

This guide compares spread betting vs CFDs, explains how each product works in practice and highlights the points to consider before deciding whether either product is appropriate for you.

What spread betting and CFD trading have in common

Spread bets and CFDs are financial derivatives. Their value is derived from the price of an underlying market, such as an index, share, ETF, forex pair or commodity. When you use either product, you do not buy or own the underlying asset.

With both products, you can take a position on rising or falling prices. You ‘buy’ or go long if you think the market will rise, and ‘sell’ or go short if you think the market will fall. Your profit or loss depends on whether the market moves in your favour or against you.

Both products are traded on margin. This means you deposit a percentage of the full notional value of the trade to open a position. Margin can make trading more capital-efficient, but it also increases risk. A relatively small market move can have a larger effect on your account because profit and loss are calculated using the full value of the position, not just the margin you deposit.

Before placing a trade, make sure you understand how margin and overnight costs work. You can review CMC Markets’ trading costs for more detail.

Main differences between spread betting and CFDs

Tax treatment

The biggest difference for many UK and Ireland-based traders is tax treatment. Spread betting profits are generally free from capital gains tax and stamp duty in the UK and Ireland. CFD profits are generally subject to capital gains tax, although CFD losses may be offset against profits for tax purposes.

Tax should not be the only reason to choose one product over another. Tax treatment depends on your individual circumstances and may change in the future. Consider seeking independent tax advice if you are unsure how either product applies to your situation.

Availability

Spread betting is available only to customers who reside in the UK or Ireland. CFDs are available in many countries, including the UK and several other major financial markets. Neither spread betting nor CFD trading is available to retail clients in every jurisdiction.

Position sizing

Spread betting uses a stake size per point of market movement. For example, if you trade £10 per point, every one-point move in the market changes your profit or loss by £10.

CFD trading uses units or contracts. Your profit or loss is based on the difference between the opening and closing price, multiplied by the number of CFD units traded.

Currency exposure

Spread bets are placed in your local currency, which means there is no currency conversion on the trade itself. CFDs are traded in the currency of the underlying market. This means your profit or loss may be affected by foreign exchange movements, and currency conversion fees may apply.

Commissions and trading costs

Both products involve the spread, which is the difference between the buy price and the sell price. Spread betting is commission-free, with an additional spread payable on shares and ETFs. CFD trading is also commission-free on many markets, but commission applies when trading share and ETF CFDs.

Holding costs may apply to both spread bets and CFDs when positions are kept open overnight. These costs can be positive or negative, depending on the market, direction of the position and applicable holding rate.

Spread betting vs CFDs: Trade example

The mechanics of a spread bet and a CFD trade can look similar when the same market, opening price and margin rate are used. The main difference is how the position size is expressed.

For this example, assume the UK 100 - Cash has the following prices and margin rate:

Sell price: 7,277
Buy price: 7,278
Spread: 1 point
Margin rate: 5%

You think the UK 100 will rise, so you open a ‘buy’ position.

Step	Spread betting	CFD trading
Opening position	You open a position at £10 per point.	You buy 10 CFD units at the buy price.
Margin calculation	5% x (£10 x 7,278) = £3,639	5% x (10 units x 7,278) = £3,639
Market movement	The UK 100 rises by 25 points.	The UK 100 rises by 25 points.
Profit calculation	25 points x £10 = £250	25 points x 10 units = £250

In this example, the margin and gross profit are the same. The differences appear in the product structure: spread betting profit is based on stake per point, while CFD profit is based on units. Taxes, commissions, holding costs and FX exposure may also differ.

Spread betting or CFDs: Which is more appropriate?

Neither product is suitable for everyone. Both are leveraged, short-term trading products, and both can result in rapid losses. The right comparison depends on where you live, how you want to size positions, which markets you want to trade, how tax treatment applies to you and whether you understand the risks.

Spread betting may be considered by eligible customers in the UK or Ireland who want to trade in their local currency and who understand the tax treatment and risks. CFDs may be considered by traders who want access to CFD markets and are comfortable with contract-based position sizing, possible currency exposure and capital gains tax treatment.

Before using either product, consider whether you understand margin, holding costs, order types, market volatility and the possibility of losing your capital.

When spread betting may be considered

You want position size to be expressed as a stake per point.

You understand that profits are generally subject to capital gains tax in the UK.
You want the potential ability to offset CFD losses against gains, depending on your circumstances.
You understand that trades may be affected by FX movements when the underlying market is priced in another currency.

Key takeaway

The main difference between spread betting and CFD trading is how the products are structured and taxed. Spread betting is available only in the UK and Ireland and uses a stake per point, while CFDs are available in more countries and use contract or unit-based position sizing. Both products are leveraged and high risk, so the decision should be based on eligibility, costs, tax treatment, currency exposure, trading objectives and whether you understand the risks involved.
