What is a treble bet? How trebles work, how to calculate returns, and football treble examples
Last updated: April 2026
A treble bet combines 3 selections into 1 bet — all 3 must win for the bet to pay out. The odds multiply together, which means trebles can produce substantial returns from modest stakes. But one loser kills the whole bet. The treble is the most popular multi-bet format in UK football — a treble football bet combining 3 Saturday match results is a ritual for millions of bettors every weekend. This guide explains how a treble bet works, how to calculate a treble bet, and the real probability behind football trebles that most bettors never think about.

How does a treble bet work?
Pick 3 selections in different events. All 3 must win. The decimal odds are multiplied together to give the combined odds.
A treble is a 3-fold accumulator. It's the step up from a double (2 selections) and the step down from a four-fold (4 selections). The maths works the same way — odds multiply — but with 3 legs the returns are significantly higher and the probability is significantly lower.
Football treble bet — the most popular format
Saturday 3pm treble
This is the classic football treble. Three selections from the Premier League Saturday fixtures:
| Selection | Match | Odds |
|---|---|---|
| A | Arsenal to win | 4/5 (1.80) |
| B | Liverpool to win | 4/6 (1.67) |
| C | Man City to win | 1/3 (1.33) |
£10 football treble:
Combined odds: 1.80 × 1.67 × 1.33 = 4.00Returns: £10 × 4.00 = £40.00Profit: £30.00Three short-priced favourites produce combined odds of 4.00 — which looks manageable. But what's the actual probability?
Each selection's implied probability:
- Arsenal: 55.6%
- Liverpool: 59.9%
- City: 75.2%
Joint probability: 55.6% × 59.9% × 75.2% = 25.0%
Your "safe" football treble has roughly a 1 in 4 chance of landing. Three-quarters of the time, it loses. That's the reality — and it's a reality most bettors never calculate before placing. The tendency to believe that three short-priced selections "should" all win is closely related to the gambler's fallacy — we overestimate the probability of combined events because we think about each leg independently rather than jointly.
Football treble at bigger odds
Three selections from the FA Cup 3rd round:
| Selection | Match | Odds |
|---|---|---|
| A | Leicester to beat Man Utd | 5/2 (3.50) |
| B | Wolves to beat Brighton | 6/4 (2.50) |
| C | Crystal Palace to beat Leeds | 2/1 (3.00) |
Combined odds: 3.50 × 2.50 × 3.00 = 26.25Returns: £5 × 26.25 = £131.25Profit: £126.25Implied probability: ~3.8%Bigger odds, bigger returns — but a roughly 1 in 26 chance of landing.
Horse racing treble
| Selection | Race | Odds |
|---|---|---|
| A | Storm Chaser, 2:30 Newbury | 4/1 (5.00) |
| B | Golden Arrow, 3:15 Ascot | 7/2 (4.50) |
| C | Dark River, 4:00 Cheltenham | 5/1 (6.00) |
Combined odds: 5.00 × 4.50 × 6.00 = 135.00Returns: £5 × 135.00 = £675.00Profit: £670.00At racing odds, trebles produce much larger returns — but the probability is correspondingly lower (~0.7% for this treble). This is where the question "should I place a treble or a Trixie?" becomes critical.
Our treble calculator computes exact returns for any odds, including each way trebles.
How to calculate a treble bet
Whether you want to calculate treble bet returns by hand or just understand the logic, here's the process. Multiply all 3 decimal odds, then multiply by your stake:
Returns = stake × odds_A × odds_B × odds_CProfit = returns − stake£10 at 2.00 × 3.00 × 4.00 = £10 × 24.00 = £240.00 (profit £230.00)
Fractional odds
Convert each to decimal first: divide numerator by denominator, add 1.
- 3/1 → 4.00
- 5/2 → 3.50
- 7/4 → 2.75
Multiply: 4.00 × 3.50 × 2.75 = 38.50. £10 returns £385.00.
Each way treble
An each way treble is 2 bets: a win treble and a place treble. £5 each way costs £10.
The win treble settles at full odds. The place treble uses place odds (typically 1/4 or 1/5 of the win odds). If all 3 win, both bets pay. If all 3 place but some don't win, only the place treble pays. If any selection doesn't place, both bets lose.
Treble vs Trixie — the key decision
A treble is 1 bet. A Trixie is 4 bets on the same 3 selections (3 doubles + 1 treble). Same selections, very different risk profiles:
| Scenario | £5 Treble (£5 stake) | £5 Trixie (£20 stake) |
|---|---|---|
| All 3 win at 3/1 | +£315 profit | +£780 profit |
| 2 of 3 win at 3/1 | −£5 loss (total) | +£60 profit |
| 1 wins at 3/1 | −£5 loss | −£20 loss |
| 0 win | −£5 loss | −£20 loss |
The treble is cheaper and pays well when all 3 win. But it gives you nothing from 2 winners.
The Trixie costs 4× more but pays from 2 winners. Two winners from 3 at decent odds is a realistic outcome — the Trixie turns that into profit while the treble returns zero.
The rule: if you're confident all 3 will win and want maximum return per pound, choose the treble. If you want protection against one selection letting you down, choose the Trixie. For horse racing at longer odds, the Trixie's coverage is particularly valuable — 2 winners from 3 at 4/1+ produces a strong double even without the treble landing.
The real probability of a football treble
Most bettors underestimate how often trebles lose. Here's the maths at different average odds:
| Average Odds | Implied Prob Per Leg | Joint Probability | Loses X out of Y |
|---|---|---|---|
| 1.50 (1/2) | 66.7% | 29.6% | 7 out of 10 |
| 1.80 (4/5) | 55.6% | 17.2% | 8 out of 10 |
| 2.00 (evens) | 50.0% | 12.5% | 9 out of 10 |
| 2.50 (6/4) | 40.0% | 6.4% | 94 out of 100 |
| 3.00 (2/1) | 33.3% | 3.7% | 96 out of 100 |
A treble of three evens shots loses 87.5% of the time. A treble at 2/1 each loses 96.3% of the time. These numbers don't mean trebles are bad bets — they mean you should stake accordingly and not expect them to land regularly.
If you find yourself placing trebles every week and increasing your stakes to recover losses, that's a pattern worth examining. Our problem gambling support page has free UK resources if betting has stopped feeling like entertainment.
What happens if one selection is void?
If one of your 3 selections is void (postponed, non-runner, walkover), the treble becomes a double on the remaining 2 selections at the same stake. If 2 are void, it becomes a single. Your bet isn't lost — it's downgraded.
The maths — is a treble worth it?
| All 3 Selections At | Combined Odds | £10 Returns | Probability |
|---|---|---|---|
| Evens (2.00) | 8.00 | £80 | 12.5% |
| 6/4 (2.50) | 15.63 | £156 | 6.4% |
| 2/1 (3.00) | 27.00 | £270 | 3.7% |
| 3/1 (4.00) | 64.00 | £640 | 1.6% |
| 5/1 (6.00) | 216.00 | £2,160 | 0.5% |
The returns scale exponentially but the probability drops just as fast. A treble at 5/1 each returns 216× your stake — but has a roughly 1 in 200 chance of landing. Trebles are entertainment, not investment. Stake small, enjoy the ride, and never bet more than you're genuinely comfortable losing.
