We created a UK spread betting calculator to understand the profit or loss or a single spread bet based on a number of variables. These include the size of the bet, price movement and the broker’s spread when making the trade.


Our spread betting calculator utilises industry average spreads for over 40 brokers and end-of-day market prices to offer the most accurate scenario possible. When using the calculator, you can choose from six major currency pairs, or if you prefer, opt for the ‘other’ category to simulate making a spread bet on another market such as the FTSE 100.

You can take some of the guesswork out of spread betting. Use our example below to explore how margin requirements, as well as profit and loss, are calculated on spread bets.

The spread bet calculator uses real market data offering a unique experience where you can calculate the profit/loss of a spread betting strategy without a trading account or platform. Over time we will continue to enhance our spread betting calculator with new financial markets and trading instruments.

1. Choose your Market

Firstly, decide on the financial market that interests you from the forex pair dropdown in the deal ticket.

Our calculator is preloaded with data for six major currency pairs to help you simulate an accurate spread betting scenario. However, if you are looking to trade a different asset, or are still unsure on the financial market you want to focus on, simply choose the ‘other’ option from the deal ticket dropdown.

Select Currency Pair

To provide a real life trading environment, the buy and sell prices for these six forex pairs are generated based on industry average spreads and end-of-day market prices. These average spreads are continuously updated and sourced from over 40 of the best brokers worldwide.

To eliminate commission fees from your profit and loss calculations, we use standard account spreads where the brokers charge no commission on top of the spread. 

2. Decide on Your Spread Betting Strategy

The next step is deciding whether you believe prices will move in an upward or downward trajectory.

If you think the market price is going to decrease, you would select ‘SELL’. Conversely, if you predict the market price is going to increase, you would select ‘BUY’.

  • Long: betting the market will rise – profit from an upwards price movement
  • Short: betting the market will decrease – profit from a downward price movement

Go Long or Short

3. Choose your Position Size

In the size field of the calculator, enter the amount per point you want to trade.

When you choose your bet, you’re specifying how much you stand to gain or lose with each point the market moves. For instance, if you would like to bet £1000 per point, you would enter 1000 in the size field.

If you chose a bet size of £1000 per point and the market moved 2 points in your favour, you would make £2,000. If the market moved 10 points against your position, you would incur a £2,000 loss.

4. Update the Opening Price

The next step is to update the opening price. This is the initial price of the market you are interested in.

The default opening price is the industry average for the currency pair selected. This is designed to give you an idea of current market conditions, yet you can change the initial opening price to whatever you please to help you test trading strategies.

For instance, if you are looking at trading strategies for the Euro vs US Dollar and the current rate is EUR/USD is 1.20, you would enter 1.20 in the opening price level field.

Alternatively, you can enter a more favourable opening price than the current market price. For instance, if you are developing a spread betting strategy where you anticipate the market price to drop to EUR/USD 1.10, you can change the price to 1.10 in the opening price field.

Opening price

5. Update the Closing Price

In the next field, you can enter your desired closing price.

The closing price point is where you aim to either secure a profit or minimise a loss depending on how the market moves. For example, if the EUR/USD is trading at 1.20 and you are aiming for a profit that corresponds to the market price dropping by 0.18 points, you would enter 1.02 in the closing price field.

Closing Price

6.  See your Profit/Loss and Margin

Once you’ve entered your position size, opening price, and closing price, the spread betting calculator will automatically calculate your potential profit and loss. This is shown in the ‘Resulting P&L’ field.

profit or loss of the spread bet

To determine your margin requirements for the bet, enter the assets margin rate in the deal ticket. For example, if the margin rate is 3.33% for EUR/USD, you would enter 3.33 in the margin field. If the bet size is 1000, the opening price is 1.20, and margin rate 3.33%, a £39.96 margin will be required.

Margin Rate = Bet Size x Opening Price x Margin Rate
Margin Rate= 1000 x 1.20 x 3.33% = £39.96

If your prediction was correct and the market price decreased to 1.02, the result of your spread betting strategy would be £180 profit. Alternatively, if the market moved 0.18 points in the opposite direction, and increased to 1.38, you would experience a £180 loss.

How Can You Calculate The Outcome Of A Spread Bet?

Spread betting allows you to speculate on the price movements of assets such as stocks, currencies, commodities, and indices. Instead of owning the asset, you place a bet on whether the price will go up (buy/long) or down (sell/short). You can check out our full guide on spread betting with forex section.

Factor In The Spread When Trading

The spread is the difference between an assets buy and sell prices.

For example take the GBP/USD currency pair. If the buy price is 1.1152 and the sell price is 1.1150, the spread is 0.0002, often referred to as 2 pips.

In forex trading, a pip stands for ‘percentage in point’ and is the smallest price movement a given exchange rate can make. If the GBP/USD decreases from 1.1150 to 1.1149, that equates to 1 pip.

Spread Betting Benefits

The United Kingdom has the highest popularity of financial spread betting due to the unique benefits permanent residents can derive. A few of the key benefits including:

  • No tax on profits
  • The ability to trade with leverage
  • A wide range of markets to trade
  • The ability to go long or short

Below is a more in-depth analysis of core benefits that have led to the increased adoption of spread betting.

Calculating Tax When Spread Betting

While there are many taxes you can incur while trading, spread betting is exempt from capital gains tax and stamp duty, one of its major advantages. To find out more about spread betting taxes, including how to calculate your tax and report your earnings, you can check out our spread betting tax page.

Financial Spread Betting Examples

Below are two examples that show a profit and a loss scenario to help understand how a spread bet outcome occurs.

Example 1: Spread betting profit

Imagine you are developing a spread betting strategy for the EUR/USD forex pair.

Your online broker’s pricing is 1.1150 to sell EUR/USD, and 1.1152 to buy EUR/USD.

You believe the Euro will strengthen against the dollar, so you buy at 1.1152 with a bet size of £10 per point.  The market moves in your favour, and when the sell price reaches 1.1172 and buy price 1.1174, you decide to close out your position.

  • Opening price level: 1.1152
  • Closing price level: 1.1172

As the market moved 20 points in your favour from 1.1152 to 1.1172, your result is £200 profit.

Points the market moved = (1.1172 – 1.1152) = 0.0020 = 20 points

Profit = 20 points x £10 = £200

Example 2: Spread betting loss

Pretend the sell price of Apple shares was $150.50 and the buy price was $150.52. Apple is due to release their quarterly results and you believe they will be positive. So, with a bet size of £5 a point, you buy at $150.52.

The results are not as positive as you’d hope, and Apple’s stock price drops. You decide to cut your losses when the spread reaches $149 to sell and $149.02 to buy.

  • Opening price level: $150.52
  • Closing price level: $149

The market moved 152 points against you, resulting in a loss of £760.

Points the market moved = $150.52 – $149 = -$1.52 = -152 points

Loss = -152 points x £5 = -£760

How To Calculate The Outcome Of Sports Spread Betting?

While with financial spread betting you are betting on the direction prices are moving in a market such as forex or commodities, sports spread betting involves betting on the outcome of a match. Unlike traditional sports betting where you bet on a single outcome at fixed odds, sports spread betting allows you to bet against a spread or range of outcomes established by the spread betting broker.

Popular sports include football (soccer), basketball, golf, tennis, American football, cricket, rugby, darts, and snooker.

Sports Spread Betting Example

Say the spread for total goals in a football match is set at 2-3.

If you feel optimistic that it will be a high-scoring game, so you decide to buy at 3 for £10 a point.

The game finishes with 5 goals being scored in total. To calculate your winnings you would take the actual number of goals scored, being 5 in this example, and subtract the point at which you bought the spread, being 3, which equals 2.

5 – 3 = 2

You then multiply this by your stake of £10, resulting in winnings of £20

Profit = 2 x £10 = £20

Spread Betting FAQs

How To Calculate Margin In A Spread Bet

The margin calculation when spread betting is: Margin = total exposure x margin factor. As a practical example, if the margin offered by a broker was 5% (know as 20:1 leverage) for exposure of £100,000 a trader would need to put down £5,000 (5% x £100,000) to open the trade.
