Bookmaker Margin in Padel: The Cost Nobody Advertises

What a margin actually is

A fair coin has two outcomes at 50% each, which as decimal odds is 2.00 and 2.00. A bookmaker offering that market would not price it there — they would offer 1.91 and 1.91, and the difference is their income.

The name changes depending on who is talking: margin, overround, vigorish, juice. They all describe the same thing, which is how much more than 100% the implied probabilities add up to.

How to work it out

Turn each price into an implied probability by dividing one by it, then add them up. A match priced 1.80 and 2.10 gives 0.556 and 0.476 — 103.2% in total. The 3.2% over is the margin.

It only works over a complete set of outcomes. Both sides of a match winner is complete; one side of it is not, and neither is a handful of set-betting prices with one missing. Adding up an incomplete set produces a number that looks like a margin and is not, which is why we only show one where we can prove the set is whole.

Why padel margins run wider

Margins are set by competition, not by generosity. Football has thousands of books fighting over the same fixtures and margins fall to two or three per cent. Padel has a handful, so nobody is forced to sharpen a price to win the bet.

The thinner the market, the worse it gets. A match with six books quoting it is priced more keenly than one with two, and the lower tiers of the FIP tour are frequently priced by nobody at all.

It is worse away from the match winner

The match winner is the market every book quotes and the one most people bet, so it carries the tightest margin on offer. Set betting, totals and handicaps carry noticeably more, because fewer people bet them and fewer books price them.

That matters when you are hunting a clever angle. The edge you think you have found in a padel handicap has to clear a margin considerably larger than the one on the match winner — often large enough to eat the whole idea.

What it costs over a season

The difference between a 3% and a 7% margin sounds academic on one bet. Over a hundred bets of the same stake it is roughly four per cent of everything you staked, taken before any question of whether your opinions were any good.

Put the other way: taking the best available price instead of an average one is worth more, over a season, than most of the handicapping people spend their time on. It requires no skill and no view. It is simply arithmetic that most people never do.

A margin beats a bonus

A welcome offer is paid once. A margin is charged on every bet you place there for as long as you have the account. A book with a generous bonus and a wide margin is a book that pays you once and charges you forever.

This is the trade nobody puts on the landing page, and it is the reason we lead with the price rather than the promotion — an offer is only the deciding factor when two books are quoting the same number, which happens more than you would think because books sharing a pricing platform quote the same price.

Measured, not asserted

Every review site ranks bookmakers on a star rating somebody typed in. The margin is the one figure about a book that can be computed from what it is publishing right now, and it is the figure that decides what you actually get paid.

So we compute it per book, per market, and show the fairest first — on the markets where the outcome set is provably complete, and nowhere else.
