Winning margin betting explained

A winning margin bet picks the winner and the size of the win. Instead of three outcomes you get eight or so: home by one, by two, by three or more, the same for the away side, and usually a score draw and a no-goal draw. The bet is on 90 minutes plus stoppage time, and only the exact band you picked wins.

How it settles

Final score	Winning band
1–0, 2–1, 3–2	Home by 1
2–0, 3–1	Home by 2
3–0, 4–1, 5–0	Home by 3+
1–1, 2–2	Score draw
0–0	No goal
0–1, 1–2	Away by 1
0–2, 1–3	Away by 2
0–3, 1–4	Away by 3+

Some books merge the draws into one outcome or extend the bands to by four or more. bet365's rules make winning margin bets no action if the match is abandoned before 90 minutes. Read the band list before you stake.

The slices add up to the result

Every home band is a piece of the home win, so the home bands must add up to the home win chance. Here is an illustrative match with the home side expected to score 1.5 goals and the away side 1.1, run through a Poisson model. These are example inputs, not a BAI8 number:

Band	Chance	Fair price
Home by 1	23.2%	4.31
Home by 2	14.0%	7.14
Home by 3+	9.2%	10.9
Score draw	18.3%	5.46
No goal	7.4%	13.5
Away by 1	17.0%	5.88
Away by 2	7.5%	13.3
Away by 3+	3.2%	31.3

The home bands sum to 46.4%, the draws to 25.8% and the away bands to 27.8%, which is the ordinary three-way result. Notice how much of the home win sits in the one-goal band: half of it. That is typical of football, where most wins are narrow.

Where the margin hides

Turn a book's winning margin prices into chances and add them up. On an eight-way market the total is usually further above 100% than on the three-way result, so you pay more for the slice than for the whole. A price that looks big can still be worse value than the plain result once you account for that. The method is in what the bookmaker's margin really costs you.

A real card, and what it cannot split

Today's Desk card for Willem II v PEC Zwolle has Zwolle at 51.8%, the draw 23.7% and Willem II 24.5%. A winning margin bet on Zwolle by one, by two or by three or more takes a share of that 51.8%, but the card does not say how big each share is. That needs a goals model, which the Desk does not publish. The same gap shows up in European handicap betting, where a one-goal win is the handicap draw.

What this does not tell you

It does not tell you which band is value; that needs your own chances and the book's prices with the margin removed. The Poisson split above is a sensible starting point but it assumes goals arrive independently, and it tends to understate draws in low-scoring leagues. BAI8 prices the match result only, so nothing here is a BAI8 call.

18+. Bet only what you can afford to lose.
