Horse Racing Bets: Where the Money Goes Before the Dividend Is Paid

A racing bet has two completely different cost structures depending on whether you took a tote price or a fixed one, and most punters use both without noticing the difference. This page works through the dividend calculation, the takeout, the fixed-odds margin and the deduction rules that change a payout after the bet is placed.

Two price types, two different fees

A tote price is not a price at all until the race is run. Every bet of that type goes into a pool, a percentage is removed, and whatever is left is divided among the winning units. A fixed price is a contract agreed at the moment you bet, and the operator carries the risk. The fee in the first case is the pool takeout; the fee in the second is the margin built into the prices. They are charged differently and they behave differently when the field changes.

How a tote dividend is actually worked out

The calculation is simple and public. Take the total amount in the pool, remove the takeout percentage, and divide the remainder by the number of winning units. That quotient is the dividend per unit. Nothing about the horse, the odds board or the crowd's opinion enters the sum except through how much money each selection attracted.

A worked pool

Suppose a win pool holds ten thousand dollars and the takeout is fifteen per cent. Fifteen hundred is removed, leaving eight and a half thousand to distribute. If a thousand dollars was bet on the winner, in units of one dollar, then eight and a half thousand divided by a thousand units gives a dividend of eight dollars fifty. Every winning dollar returns eight fifty, and that is the whole of the mechanism.

What the takeout really means for you

Takeout is removed before any result is known, which makes it the purest form of house edge in gambling: it is charged whether you win or lose, and it does not depend on anybody's judgement. A fifteen per cent takeout means the pool pays back eighty-five cents in the dollar across all participants, every time, by construction. Takeout rates differ by bet type, and they are generally higher on the exotic pools.

• Dividend = (pool - takeout) / winning units.
• The takeout is charged before the race is settled, on everybody.
• Exotic pools usually carry a higher takeout than win and place pools.
• A late plunge changes your dividend after you have bet, because the pool shares shift.

Fixed odds and the margin across a field

With fixed odds the cost is calculable the same way as in any other sport: divide one by each price to get an implied probability, then add every runner in the field. A fair book totals one. A racing book routinely totals well above it, because there are many runners and each one is a place to carry margin.

A worked field

Take a twelve-runner race where the implied probabilities add to one point twenty-five. The book is carrying twenty-five per cent over fair, which means that across all runners the operator expects to return eighty cents in the dollar. That figure is directly comparable with a tote takeout, and comparing them is the single most useful thing a punter can do with ten minutes and a calculator.

• Implied probability = 1 / decimal odds, summed across every runner.
• The excess over 1.00 is the book margin, and it is comparable to a pool takeout.
• Bigger fields generally carry wider books.
• A price that looks good in isolation says nothing about the book it sits in.

Scratchings and the deduction nobody budgets for

If a runner is withdrawn after you have taken a fixed price, the race you bet into no longer exists: your selection is now more likely to win than it was when the price was set. Operators handle this with a deduction from the payout, calculated from the price of the withdrawn runner on a published scale. The bet is not voided and the odds on your ticket are not changed — the payout is reduced.

What to check before it happens

The operator publishes its deduction scale and the point at which deductions start applying. The important details are which prices the scale is based on, whether there is a time after which a scratching no longer triggers a deduction, and whether tote and fixed bets are treated differently. On a race with a shortly priced runner in doubt, this is a larger factor than almost anything else about the bet.

• A deduction reduces the payout; it does not void the bet or change the stated odds.
• The scale is derived from the withdrawn runner's price, so a short-priced scratching costs the most.
• Tote bets handle withdrawals through the pool instead, which is a different mechanism.
• Check the operator's rule, not the convention you remember from somewhere else.

Each-way is two bets, and the place half is the expensive one

An each-way bet is a win bet and a place bet of the same size, which means a fifty dollar each-way bet costs a hundred dollars. The place portion pays at a fraction of the win odds, or from a separate place pool, depending on the bet type. People consistently underestimate both the stake and the cost structure, because the ticket shows one number and charges two.

How to think about it

Treat it as two separate decisions and price each one. Would you place that win bet at that price for that stake? Would you separately place that place bet at that return for that stake? If the answer to the second is no, you are buying it because it came attached, which is the opposite of a reason. 18+ only; Gambling Help Online is free at any hour on 1800 858 858.

• An each-way stake is double the figure you typed.
• The place return is a fraction of the win odds, or a separate pool dividend.
• The number of paid places varies with the size of the field, under the operator's rules.
• Promotions frequently exclude the place portion, or exclude each-way bets entirely.

Where to read on

Each of these covers one part of the same arithmetic in more detail, so you can check a figure rather than take it on trust.

The small print that actually matters

18+ and where to get help

Everything on this page is information about how money moves, not advice to gamble and not a promise that any bet or spin returns anything. Wagering is for adults over 18 only. If the amounts, the chasing or the hours have stopped feeling like a choice, Gambling Help Online is free, confidential and open at any hour on 1800 858 858, and BetStop is the national self-exclusion register for licensed Australian wagering operators — it does not reach offshore online casinos, which is one more reason to decide the limit before the deposit rather than after it.
