While traditional bookmakers earn through margins built into the odds, Betfair Exchange works differently — it simply connects bettors and takes a small cut from the winner’s profit. That small cut, known as commission, has always been central to how Betfair operates. But in 2025, the structure has evolved. Betfair has introduced a new Expert Fee system, replacing the older “Premium Charge” model that frustrated many professional traders.
This article breaks down how Betfair’s commission and fees now work in 2025 — what’s changed, who it affects, and how to manage your costs whether you’re a casual bettor, a high-frequency trader, or an iGaming industry professional trying to understand how exchange economics really function.
What Is Betfair Commission and How Does It Work?
Betfair Exchange isn’t like a regular bookmaker. When you place a bet on Betfair, you’re not betting against the house— you’re betting against another user. Betfair’s role is simply to act as a middleman, matching your bet with someone on the opposite side.
When your bet wins, Betfair charges a commission on your net winnings for that market.
For example:
If you back Manchester United at odds of 2.0 for £100 and they win, your gross profit is £100. Betfair takes, say, 5% commission on that profit — meaning you keep £95.
If you lose, Betfair doesn’t charge anything. You only pay commission on net profit, never on stakes or losing bets.
This commission is what keeps the platform running, covering costs of liquidity, technology, and support, while still offering better odds than traditional bookmakers.
2025 Update: The End of Premium Charge
Since 2008, Betfair had an additional layer of fees called the Premium Charge — an extra cost for users who won too often or too efficiently. The idea was to ensure “fair contribution” from high-profit accounts who generated little commission relative to their winnings.
However, this model was widely criticized for being confusing, restrictive, and permanent. Once you qualified, you could be stuck paying up to 60% of your profits indefinitely.
In January 2025, Betfair finally retired this system and replaced it with something more modern, transparent, and flexible — the Expert Fee.
The Expert Fee Explained
The Expert Fee is Betfair’s new way of balancing the ecosystem while keeping most users unaffected. It’s designed to target only the most profitable traders on the platform — those generating high, consistent profits over time.
How It Works
Instead of looking at lifetime profit (like the Premium Charge did), the Expert Fee uses a rolling 52-week profit calculation. This makes the system much fairer — your fee level can go up or down depending on your recent performance.
Here’s the 2025 structure:
- If your total gross profit over the past 52 weeks is below £25,000, you pay no Expert Fee.
- If your profit is between £25,000 and £100,000, you pay an additional 20% on profit after accounting for buffer and regular commission.
- If your profit exceeds £100,000, your Expert Fee rises to 40%.
This means 80% of Betfair’s users won’t be affected at all — the platform claims the fee applies only to “top-tier” professional traders.
Why Betfair Introduced the Expert Fee
The main reason for this change was to make the system more dynamic and less punishing. The Premium Charge used to feel like a penalty that never went away once you triggered it.
The Expert Fee, on the other hand:
- Reflects your recent trading performance instead of lifetime records.
- Allows you to fall out of the fee bracket if your activity or profits decrease.
- Encourages consistent market contribution by rewarding liquidity providers who play fairly.
For Betfair, it’s also a way to stabilize revenue while maintaining user trust — especially as exchanges become more competitive and decentralized betting models grow.
Standard Commission Rates (Market Base Rate)
Every Betfair user still pays a standard Market Base Rate (MBR) commission on net winnings. This is separate from the Expert Fee.
In most countries, the default commission rate is 5%. However, this varies depending on:
- Region (different rates in the UK, Europe, and Australia)
- Sport or market type
- Promotional or loyalty discounts
For example:
- In the UK and Europe, the base rate generally stays at 5%.
- In Australia, some states charge 6–10% depending on regulations.
- Heavy users may qualify for discounts, reducing their effective rate to as low as 2%.
In simple terms:
Everyone pays standard commission on winning bets. Only high-profit traders may pay extra Expert Fees.
Understanding “Commission Generated”
Betfair’s fee system isn’t based purely on what you win or lose. It also accounts for something called commission generated, which includes both:
- Actual commission paid on winning bets
- Implied commission on losing bets
This metric ensures that users who trade actively — even with both wins and losses — aren’t penalized as harshly as those who win consistently without generating much turnover.
For instance, if you win £10,000 and lose £8,000 across different markets, Betfair will consider how much “commission activity” your account generated, not just the headline profit. It’s a way to reward active liquidity providers rather than purely profitable accounts.
Regional Differences in 2025
While the new Expert Fee applies globally, base commission rates still vary by country.
- United Kingdom & Europe: Still around 5%, with no major structural changes.
- Australia: Betfair increased its base rate on non-racing markets from 5% to 6% in March 2025, and racing commissions vary by state (some as high as 10%).
- Asia and LATAM: Betfair operates under partner licenses; base rates usually mirror the 5% benchmark but may fluctuate based on local taxes.
For international traders, it’s worth checking your local Betfair site for the latest MBRs, since even a 1% difference can affect long-term profitability.
How to Minimize Your Fees
Here are a few ways to keep your costs under control on Betfair Exchange:
- Trade Consistently, Not Aggressively
Avoid large, high-margin swings that push your annual profit into the next bracket. - Build Your Buffer
Remember that losses and commission create a “credit” against future Expert Fees. Trading more actively (even with small losses) can lower your effective rate. - Track Your Rolling 52-Week Profit
Betfair provides performance analytics in your account dashboard. Monitor your progress to stay below thresholds. - Utilize Betfair Discounts
Loyalty programs or volume-based incentives can reduce your base commission rate over time. - Diversify Markets
Trading in multiple sports and regions can spread your activity, lowering the impact of a single profitable segment.
In short: manage your profit rhythm, not just your win rate.
Why This System Is Better
Many experienced traders agree that the Expert Fee is a major improvement over the old Premium Charge. Here’s why:
- It’s temporary, not permanent.
- It’s based on performance, not account age.
- It’s predictable and transparent — Betfair explains exactly how the calculation works.
- It makes room for new traders to grow without fear of being hit by lifetime penalties.
By aligning fees with recent activity, Betfair has modernized its ecosystem — something the exchange model has needed for years.
Conclusion
As of 2025, Betfair’s commission system has entered a new era. The base commission — still around 5% — remains simple and familiar. But the Expert Fee now replaces the old Premium Charge, offering a fairer, more flexible framework for high-performing traders.
For everyday users, nothing much changes. You’ll keep enjoying the same great odds and liquidity Betfair is known for. For serious traders, the key is awareness — understanding where your profit stands and how to optimize your strategy to minimize fees. And for the iGaming industry, Betfair’s 2025 shift shows the future of exchange economics: transparent, data-informed, and user-centered.
