How To Calculate Doubles, Trebles And Accumulators
Returns from win doubles, trebles and accumulators are easily calculated by adding one point to the price of each horse, and multiplying the new figures.
Thus, a 2-1 and 4-1 double, with a point added, becomes 3 x 5 = 15, which is a 14-1 double. If it is a £1 double the return, will be £15.
If there are fractions, the same procedure of adding one unit is followed.
Thus, 5-2 and 5-1 in a double are expressed as 5/2 and 5/1
Add the figure which follows / to the figure in front of it, thus: 7/2 and 6/1
Multiply in the usual way, and the answer is the return, including stake.
7/2 x 6/1 = 21 or a 20-1 double
Return for a £1 double is therefore £20 plus the original stake of £1. Total Return £21
In calculating place bets, the simplest way is to multiply the SP by four or five, as the case may be for fourth odds or fifth odds.
Thus 5-4 place at quarter odds is 5/16ths and 5-4 place at fifth odds is 5/20, or 1/4
Thus 5-2 place at quarter odds is 5/8ths and 5-2 place at fifth odds is 5/10, or 1/2
Thus 11-4 place at quarter odds is 11/16ths and 11-4 place at fifth odds is 11/20ths
In calculating Tote bets, the easiest way is to convert the Tote dividend to SP, and then calculate as for SP bets. Dividends are expressed to 10p units including stake, so a 35p dividend is 25 - 10 or 5 - 2. A 55p dividend is 9-2. A £1.20 dividend is 11-1. A treble, with dividends of 25p, 55p and 18p would be 25-10, 55-10 and 18-10, or 6-4, 9-2 and 4-5.

Easy Way To Calculate Multiple Bets
This swift, simple method can be used to calculate any full cover bet (every combination of singles, doubles, trebles, etc, such as Patent) provided all bets are at the same stake.
Add two points to the SP of each winner, multiply the 'new' prices together, then deduct one unit stake from the result. The answer will be the total return due from the bet.
Example 1: 10p win Patent, winners at 2-1, 3-I and 6-4
Add two points and multiply:
4 x 5 x 3.5 = 70 times 10p = £7.00
Deduct one unit stake: £7.00 less 0.10 = £6.90
Example 2: 4 x 10p singles, 6 x 10p doubles, 4 x 10p trebles,
1 x 10p accumulator. £1.50 staked.
Winners at 2-1, 3-1, 6-4 and evens.
Add two points and multiply:
4 x 5 x 3.5 x 3 = 210 x 10p = £21.00
Deduct one unit stake:
£21.00 less 0.10 = £20.90
Those who may be discouraged by multiplication can reach the same result by adding one point to each SP and working out an accumulator. Thus, using the winners in Example 2, the prices become 3-1, 4-1, 5-2 and 2-l. 10p at 3-1 is 40p; 40p at 4-1 is £2.00; £2.00 at 5-2 is £7.00; £7.00 at 2-1 is £21.00. Deduct one unit stake of 10p and the answer is £20.90.
Mixed doubles, trebles, accumulators, Trixies, Yankees, Canadians, Heinz bets, etc, where singles are not included, can easily be calculated by the same methods. In such cases, all you have to do is to deduct a single return at the actual SP for each winner, from the total.
Thus, a Yankee, with winners as in Example 2: Deduct 30p, 40p, 25p and 20p (£1.15) from the £20.90 total, to give a Yankee return of £19.75.
