Individual arbs usually return only a small percentage. What decides your monthly total is bankroll, how many opportunities you place and how well you protect your accounts. Here are realistic UK numbers.
Quick answer
Most UK arbitrage bettors earn anywhere from a few hundred pounds to over £1,000 per month, depending on their bankroll, the number of opportunities they place and how efficiently they use arbitrage betting software. While each individual arbitrage usually returns only a small percentage, consistent betting across multiple opportunities can produce a reliable secondary income over time.
If you're researching how to make money arbitrage betting, one of the biggest questions you'll probably have is: "How much can I actually make?" The honest answer is that it depends.
Unlike traditional sports betting, arbitrage betting isn't about predicting winners. Instead, you're taking advantage of pricing differences between bookmakers to secure a profit regardless of the outcome. That doesn't mean every bettor earns thousands every month. Your earnings depend on factors such as your bankroll, how often you place bets, the number of opportunities you can find and how efficiently you manage your accounts.
In this guide we'll explain how much money you can make arbitrage betting, provide realistic UK examples and show you the factors that have the biggest impact on long-term profitability.
Yes — but only if you approach it correctly and know how to get started arbitrage betting.
Arbitrage betting works because bookmakers don't always price markets identically. When the odds differ enough, it's possible to back every outcome across different bookmakers and lock in a guaranteed profit after staking the correct amounts. Rather than gambling on the result, you're exploiting market inefficiencies.
This means your profits come from:
Because each individual arbitrage usually returns a relatively small percentage, successful arbitrage betting relies on consistency rather than one huge win.
What the data says
The Gambling Commission estimates that around 25 million adults in Great Britain gambled in the past four weeks during 2025, highlighting the scale and liquidity of the UK betting market where arbitrage opportunities can arise across multiple bookmakers.

There isn't a fixed figure because everyone's circumstances are different. Some bettors make only a few hundred pounds per month, while others generate several thousand pounds by investing larger bankrolls and treating arbitrage betting like a structured side income.

What the data says
Official industry figures show Britain's gambling industry generated £16.8 billion in Gross Gambling Yield during the year to March 2025, with online gambling contributing £7.8 billion. This demonstrates the scale of the competitive online betting market that arbitrage bettors operate within.
These figures assume disciplined bankroll management and consistent access to quality arbitrage opportunities.
The biggest factor is your available betting bankroll. Because arbitrage profits are usually only a few percent per bet, larger stakes naturally produce larger returns. For example:
This is why experienced arbitrage bettors often reinvest profits and gradually increase their bankroll over time.
More opportunities generally lead to more profits. Finding profitable arbitrage bets manually can take hours every day, and many opportunities disappear within minutes. Using specialist software such as the OddsMatcher dramatically increases the number of opportunities you can place before markets move.
OddsMonkey expert insight
"Many bettors focus solely on finding more arbitrage opportunities, but consistency often comes from being selective. Prioritising well-priced markets with sufficient liquidity and reliable bookmakers usually produces steadier long-term returns than chasing every small percentage edge available."
Lora Savage, OddsMonkey Arbitrage Betting Expert
Arbitrage opportunities rarely last long. Professional bettors can identify and place both sides of an arbitrage in under a minute. The quicker you act, the more successful you'll be.
One of the biggest challenges with long-term arbitrage betting is account restrictions. Bookmakers may limit stake sizes or restrict promotions if they believe you're consistently exploiting pricing inefficiencies. This is why many experienced bettors spread bets across multiple bookmakers, avoid placing obviously calculated stake amounts and mix in recreational betting activity where appropriate.
Some sports generate more arbitrage opportunities than others. Popular sports typically offer more bookmakers, greater market liquidity and more frequent odds movement. Football arbitrage betting generally provides the greatest number of opportunities, followed by tennis arb betting, basketball and horse racing.

Profit on a £400 total stake
£16.38
After calculating the correct stakes, you invest £400 across all outcomes for a guaranteed return of £416.38 — a guaranteed profit of £16.38.
While £16.38 might not sound exciting, repeating this consistently across dozens of opportunities each month is where profits begin to grow. This article isn't about calculating arbitrage bets, so we won't get bogged down in the maths — the OddsMonkey Dutching Calculator is the ideal tool for calculating arbitrage bets just like our example.
For most people, probably not. Although some professional bettors earn substantial amounts, arbitrage betting becomes increasingly difficult as bookmakers begin restricting successful accounts.
OddsMonkey expert insight
"Long-term profitability isn't just about the size of your bankroll; it's about preserving access to profitable markets. Bettors who manage their accounts carefully often maintain earning potential for much longer than those who simply maximise short-term returns."

For the average UK bettor, arbitrage betting is better viewed as a profitable side hustle, a way to grow an existing betting bankroll, or a complementary strategy alongside matched betting.
Those expecting to become wealthy overnight are likely to be disappointed. Those who stay disciplined and realistic often enjoy far more sustainable results.
If your goal is to maximise long-term profits, focus on improving efficiency rather than chasing higher-risk opportunities.
Some of the most effective approaches include:
Instead of withdrawing every profit, consider reinvesting some of your winnings to increase future stake sizes.
Professional software can:
This allows you to place more profitable bets in less time.
The more bookmaker accounts you have, the greater the number of arbitrage opportunities available. Having access to a betting exchange creates more opportunities too. What you use most will depend on your arbitrage betting strategy. This also reduces your dependence on any single bookmaker.
Tracking profits, bankroll and bookmaker balances makes it easier to identify what's working and ensures you always have funds available where they're needed. The OddsMonkey Profit Tracker is built for exactly this.
It doesn't have to be a case of arbitrage betting vs matched betting. Many UK bettors eventually combine both strategies. Matched betting often provides larger returns from bookmaker promotions, while arbitrage betting generates profits from pricing differences.
Some people ask whether it is safe to arb as part of your matched betting strategy. Using both approaches together can provide more consistent earning opportunities throughout the year. Neither strategy is inherently "better" — they simply generate profits in different ways.
If you're wondering why your profits aren't growing as quickly as expected, these are the most common reasons:
Avoiding these mistakes often has a bigger impact than finding more arbitrage opportunities. With tools such as the OddsMatcher, Arbitrage Calculator, Dutching Calculator and Implied Probability Calculator, you can work out stakes in seconds and minimise errors.
The bottom line
"Most successful UK arbitrage bettors focus on steady, repeatable profits rather than spectacular wins. By treating arbitrage betting as a long-term strategy and combining it with good bankroll management, it's possible to generate a reliable secondary income over time."
For many UK bettors, yes. If you enjoy analysing markets and taking a disciplined approach, arbitrage betting offers one of the few betting methods capable of generating mathematically positive returns.
However, it's important to have realistic expectations. Most successful bettors don't make life-changing money overnight. Instead, they build profits gradually by:
Like any profitable strategy, success comes from discipline rather than luck.
If you're asking "how much can I make arbitrage betting?", the answer is that your earnings are largely determined by your bankroll, consistency and the tools you use.
Ready to maximise your arbitrage betting profits? OddsMonkey combines real-time OddsMatcher software, powerful calculators and market data to help you identify profitable arbitrage opportunities faster. Whether you're starting with a small bankroll or looking to scale your returns, the right tools can make a significant difference over time.
You can make your first arbitrage profit as soon as you find and place a qualifying opportunity correctly. However, most bettors build meaningful returns over weeks or months by consistently placing multiple arbitrage bets rather than relying on occasional opportunities.
Arbitrage betting can provide a consistent secondary income if you have sufficient bankroll, access to quality opportunities and manage your accounts carefully. Earnings are generally more predictable than traditional betting, but they are not guaranteed over the long term due to bookmaker restrictions and changing market conditions.
Yes. Because arbitrage profits are usually a small percentage of your total stake, increasing your bankroll allows you to stake more on each opportunity and potentially generate higher overall returns while maintaining the same percentage profit.
Yes. If bookmakers limit your stakes or restrict your account, your ability to place profitable arbitrage bets may decrease. Using multiple bookmakers, varying your betting activity and following sensible account management practices can help extend the lifespan of your accounts.
It can be. Although profits will be smaller initially, many bettors start with a modest bankroll, gain experience and gradually increase their stakes by reinvesting profits. The key is focusing on consistency rather than expecting large returns immediately.
Your bankroll is important, but so are the number of opportunities you can find and how quickly you can place them before the odds change. Many experienced bettors use arbitrage betting software to improve both speed and efficiency.
