Lucky 31 calculator

How to use the Lucky 31 calculator

1. Enter your unit stake, the amount on each bet. A £1 Lucky 31 costs £31 in total. A 50p Lucky 31 costs £15.50. Each-way doubles the number of bets to 62, so a £1 each-way Lucky 31 costs £62.
2. Pick fractional, decimal or American odds. The calculator converts all five prices for you.
3. Enter the price for each of the five selections and mark each as Win, Place, Lose or Void.
4. Tick each-way if you want the place part, then choose the place terms (1/4, 1/5 or your own fraction).
5. Add a Rule 4 deduction or a dead heat to any selection if one applies.
6. Read the total stake, total returns and profit, plus the breakdown for singles, doubles, trebles, four-folds and the five-fold.

What is in a Lucky 31?

A Lucky 31 is a full-cover bet on five selections. It contains 31 separate bets:

Because the singles are included, one winner still returns something. For a version with four selections and 15 bets, use the Lucky 15 calculator. A Lucky 63 adds a sixth selection and 63 bets. For full-cover bets without the singles, such as the Yankee, Canadian and Heinz, use the bet calculator.

Lucky 31 worked example

Take a £1 Lucky 31 on five selections priced 2/1, 3/1, 4/1, 5/2 and 6/1.

If all five win, the returns are:

The stake was £31, so the profit is £4,288.00.

Now the 50p Lucky 31 with the same selections. The stake is £15.50 and every return is halved, so the total returns are £2,159.50.

How many winners do you need on a Lucky 31?

With one winner you only get that selection's single back at its odds. At 2/1 that is £3.00 from a £31 stake. With two winners you also get the double. With 2/1 and 3/1 winning at £1 a bet, the singles return £7.00 and the double £12.00, £19.00 in total from £31. The bet starts to pay for itself from about three winners, depending on the prices. The more winners you have, the more the doubles, trebles and four-folds add up.

Each-way Lucky 31

An each-way Lucky 31 puts a win part and a place part on all 31 bets, so there are 62 bets and the total stake is double the unit stake. The place part pays a fraction of the win odds (1/4 or 1/5 for most races), and a selection that places but does not win still returns on its place parts. Check the place terms for each race before you set them in the calculator.

Non-runners, Rule 4 and dead heats

• Void or non-runner: the leg is treated as having odds of 1.00. The bets it was in still stand, but as smaller bets (a double becomes a single, for example), and its own single is refunded.
• Rule 4: when a horse is withdrawn, a deduction in pence in the pound can be taken from the winnings of the remaining selections. Enter the deduction on the affected selection and the calculator reduces its odds before it settles the bets.
• Dead heat: when two or more selections tie, the stake on that part is divided between them. Enter the number of runners involved.

Typical bonuses

Some bookmakers add extras on full-cover bets, such as a bonus when all selections win or a consolation when only one wins. Terms differ by bookmaker and change often, so check the operator's current terms before relying on any bonus. The optional bonus fields in the calculator show these as separate lines and are for illustration only.
