What the Premium Charge Actually Is
The Premium Charge is a weekly fee Betfair adds on top of standard commission for accounts that pass three lifetime tests: commission paid is below 20% of lifetime adjusted profits, lifetime adjusted profits exceed £1,000, and more than 250 markets have settled. When all three pass, Betfair takes 20% of that week's net profit minus the commission already paid. A stricter 50% tier applies to a smaller group of long-term winners. Losing weeks are never charged, and most accounts never pay it.
It is a clause in Betfair's terms of service, not a tax or a penalty, and it activates automatically. Both tiers are calculated weekly. The charge is debited from your balance every Wednesday and shown on your account statement as "Premium Charge". Betfair publishes the calculation method in its terms; it is not negotiable.
Why It Exists
Commission is taken from net market winnings, not gross profits. Traders with high turnover and a low margin per trade therefore pay little commission relative to the size of their wins, while recreational losers contribute disproportionately more.
Betfair needs long-term traders, because they provide the liquidity recreational users trade against, but regards them as under-charged at standard commission. The Premium Charge corrects that imbalance. It targets the small minority of accounts that pass all three lifetime tests: those that have won consistently for long enough that Betfair classifies them as professional users.
Tier 1 — the 20% Charge
An account is charged 20% of its weekly net profit if, in that week, it passes all three of these tests at lifetime level:
- Lifetime gross commission paid is less than 20% of lifetime market base rate adjusted profits.
- Lifetime market base rate adjusted profits exceed £1,000.
- The account has settled more than 250 markets across its lifetime.
If any one test fails, there is no charge that week. If all three pass and the week is profitable, the charge is 20% of (net profit minus standard commission already paid that week).
New accounts almost never trigger it, because they have not yet reached the 250-market or £1,000 thresholds. Long-term losing accounts never trigger it, because their lifetime profit is not above £1,000.
Tier 2 — the 50% Charge
The 50% tier, introduced in 2011, applies to a smaller subset of accounts that meet stricter conditions. The exact rules have changed since then; in outline:
- Lifetime gross commission paid is less than 40% of lifetime market base rate adjusted profits.
- Account has been on the exchange for an extended qualifying period (Betfair's calculation, not publicly fixed).
- Number of weeks where the account has paid the 20% Premium Charge exceeds Betfair's published threshold.
Reaching this tier means an account has profited consistently and substantially, week after week, for years. It is Betfair's hardest economic limit on systematically winning accounts.
The 50% tier exists and people pay it. If you build a profitable trading business on Betfair over several years, expect to meet it, and include it in your P&L model from the start.
The Three Tests Explained
Test 1 — the commission/profit ratio
Divide lifetime gross commission paid by lifetime market base rate adjusted profits. The test passes, counting towards the charge, when the result is below 20%.
| Lifetime commission | Lifetime adjusted profit | Ratio | Test 1 |
|---|---|---|---|
| £4,000 | £15,000 | 26.7% | Fails (plenty of commission already paid) |
| £4,000 | £35,000 | 11.4% | Passes (well below 20%) |
The test asks whether the account has paid Betfair enough commission to justify its profits. Below 20%, the answer is no, and the charge tops up the gap.
Test 2 — the £1,000 lifetime profit threshold
Lifetime market base rate adjusted profits must exceed £1,000. Anyone trading seriously for 3-12 months will have passed it. It exists to exclude tiny fluctuations and accounts that are essentially break-even.
Test 3 — the 250-market threshold
A market is a single Betfair market (Match Odds, Correct Score, To Be Placed and so on) and counts once at least one bet in it has settled. An active racing trader reaches 250 markets in 2-4 weeks; a casual football bettor in 3-6 months. The threshold filters out one-off lucky accounts.
How market base rate adjustment works
"Market base rate adjusted profits" means profits weighted by the standard commission rate of the markets traded. UK racing is currently 2%, football and tennis are typically 5%, and some niche markets are higher. Profits in low-base-rate markets count more heavily because Betfair takes less commission from them. The adjustment keeps the charge logic consistent whichever markets you specialise in.
Worked Example — Casual Trader
Lifetime stats: Markets settled: 410. Lifetime market base rate adjusted profits: £4,200. Lifetime commission paid: £1,260.
Test 1: 1260 ÷ 4200 = 30.0%. Above 20%. Test 1 fails.
Conclusion: No Premium Charge. The account has already paid plenty of commission relative to its profits.
Why this is the most common outcome: Most profitable accounts settle at a 25-40% commission/profit ratio because they trade higher-base-rate markets (5%+ on football), so they never trigger the charge.
Worked Example — 20% Tier
Lifetime stats: Markets settled: 18,400. Lifetime market base rate adjusted profits: £92,000. Lifetime commission paid: £14,720.
Test 1: 14720 ÷ 92000 = 16.0%. Below 20%. Passes.
Test 2: £92,000, well above £1,000. Passes.
Test 3: 18,400 markets, far above 250. Passes.
Result: Premium Charge applies in any profitable week.
This week: Net profit £3,200, commission already paid £540.
Charge calculation: 20% × (£3,200 − £540) = £532 charge debited Wednesday.
Effective combined rate: (£540 + £532) ÷ £3,200 = 33.5% of net profit. The trader keeps 66.5% of weekly profit instead of ~83%.
Worked Example — 50% Tier
Lifetime stats: Markets settled: 75,000+. Lifetime market base rate adjusted profits: £680,000. Lifetime commission paid: £71,400.
Test 1: 71400 ÷ 680000 = 10.5%. Below both 20% and 40%.
Result: 50% Premium Charge tier applies.
This week: Net profit £18,000, commission already paid £2,400.
Charge calculation: 50% × (£18,000 − £2,400) = £7,800 charge debited Wednesday.
Effective rate: (£2,400 + £7,800) ÷ £18,000 = 56.7% of net profit. The trader keeps 43.3% of weekly profit.
What this means: At this tier, plan around take-home profit, not headline gross profit.
How to Manage Exposure
Once the Premium Charge is a realistic prospect, the options fall into three categories.
1. Diversify across markets
Because the commission/profit ratio is lifetime, trading higher-base-rate markets (football at 5%, niche US sports at 6-7%) pushes it higher. A trader with 90% of lifetime activity on 2% UK racing will hit Tier 1 fast; one split 50/50 across racing and football pushes the trigger further out.
This only makes sense if you have a real edge in those markets. Trading without an edge to manage the Premium Charge is just losing money more slowly.
2. Operate with realistic P&L assumptions
Build the charge into your trading model from the start. Strategy backtests should assume a 25-40% combined commission and Premium Charge cost on the winning portion of trades. A strategy that does not survive that haircut is not a real edge.
3. Run multiple legitimate accounts where allowed
Betfair's terms permit one account per individual. Multiple accounts under the same name or at the same address will be detected and closed. Do not attempt to bypass account limits.
Professional trading shops do sometimes operate separate accounts under different real beneficial owners, such as a partner or co-trader. Each account is its own entity, with its own deposits, identity verification and trading activity. This is a structural choice, not an evasion mechanism.
Multiple accounts under fake identities or duplicate addresses breach Betfair's terms and lead to permanent closure with funds withheld. Anyone selling a workaround to the Premium Charge is selling a route to a closed account.
Myths and Misunderstandings
- Myth: "Anyone who wins on Betfair pays Premium Charge." Reality: Only accounts that pass all three lifetime tests at once pay it. Most winners never do.
- Myth: "The Premium Charge stops people winning." Reality: It takes a larger share from consistent high-volume winners, but it is a share of weekly profit, so a profitable week stays profitable.
- Myth: "Closing your account resets the lifetime tests." Reality: Betfair keeps lifetime statistics tied to verified identity. Re-opening an account does not reset them.
- Myth: "If I make small bets, I can avoid it." Reality: Test 3 counts markets settled. Stake size does not matter.
- Myth: "Tier 2 is gone or never enforced." Reality: Tier 2 is active and enforced. Long-term winners pay it weekly.
Where Premium Charge Doesn't Apply
- Sportsbook activity. The charge applies only to exchange bets. Betfair's fixed-odds Sportsbook uses standard sportsbook account management, including bet restrictions on winners, but not the Premium Charge.
- Other exchanges. Betdaq and Smarkets each currently charge 2% commission with no Premium Charge equivalent. Their liquidity is much lower than Betfair's, so many strategies that work on Betfair do not survive there.
- Matched betting and bonus capture. Activity aimed at bookmaker bonuses rather than exchange profit tends not to trigger the lifetime tests, because lifetime profit on the exchange leg stays modest. See the matched betting guide.
The Bottom Line
The Premium Charge is an automatic, formula-driven fee based on three lifetime tests, and it applies to a small minority of users, typically full-time, multi-year traders. For a beginner it is years away; focus on developing an edge. Between 12 and 24 months in, track where you sit on the lifetime tests and start modelling the charge. For a full-time trader it is an operating cost like any other.

Start Trading Smart on Betfair
If you're nowhere near the Premium Charge thresholds yet, focus on developing an edge. The charge is a problem to manage when you have one — not a reason to avoid the exchange.
