Lucky 31 offers an exciting yet fairly complex way of placing multiple bets with the same stake. It’s essentially a bundle of singles, doubles, trebles, 4-leg accumulators, and 5-leg accumulators, all combined into a single wager that comprises a total of 31 outcomes, hence the name “Lucky 31”.

Choosing 5 players, horses, or teams suitable for this form of betting can be difficult enough, but pinpointing an optimal wager can be equally challenging. We present to you our free Lucky 31 Bet Calculator, a simple tool that can help you accurately narrow down your potential profits for all or individual portions of your Lucky 31 bets.

Steps to Use Our Lucky 31 Bet Calculator

In a nutshell, you only need to copy the odds from your chosen bookmaker for each leg of your Lucky 31 bet and input your total stake at the bottom of the calculator. Below is a quick step-by-step guide on how to use our free Lucky 31 Bet Calculator:

Step 1: Select Winners/Losers and Input Odds for Each Selection

The five selections in the “Outcome” column include five singles, ten doubles, ten trebles, five 4-fold accumulators, and one 5-fold accumulator bet. By default, these selections will be selected as “Winners”, but you can tap the arrow to change the fields to “Lost” (or “Dead Heat” and “Void” if you’re betting on horses).

In the next column, simply input the odds your bookmaker offers in the decimal format. You can change the odds format by tapping the cog icon in the top right corner.

Step 2: Input Your Bookmaker’s Lucky 31 Bonuses

Most bookies offer bonuses for Lucky 31 betting, such as the “All Winners” and “One Loser”, or insurance-type promos like “One Winner Consolation”. If your bookie offers such deals, copy the bonus amounts (expressed in percentages) into the corresponding fields, or simply type “0” if no bonuses are available.

Step 3: Input Your Stake in the Summary Screen

The last step requires you to input the amount of money you wish to place on your Lucky 31 wager.

The majority of UK bookies utilize the “stake per bet” format for their supported Lucky 31 betting options. If your bookmaker follows a different format where one wager is split across 31 smaller bets, simply tap on the arrow in the “Stake Type” row to change this field to “Total Combined Stake”.

After you’ve typed the odds and the wager, the Summary screen will display your total wager (outlay), total return, and total profit (return minus outlay).

(Optional) Step 4: Preview the Performance of Individual Wagers in Alternative 5 Selection Bets Screen

Although it’s possible, winning all 31 bets in a Lucky 31 is quite rare. That’s why our free calculator tool also includes an alternative Summary table that lists the estimated returns on individual bets that comprise your Lucky 31 wager with the stake and odds you provided.

The only difference in this screen is that bonuses are not calculated since they may vary from one type to another.

Lucky 31 Calculator Formula

Our free Lucky 31 bet calculator is based on several mathematical formulas that some of our other tools utilize. Namely, this software individually calculates singles, doubles, trebles, 4-leg accumulators, and 5-leg accumulators based on the odds and the stake you provided to calculate their payouts.

These payouts are then summed to show your total profit; your estimated returns are calculated by subtracting your total combined stake from the total profits.

How Our Lucky 31 Calculator Can Help

It’s easy to place a small Lucky 31 punt and rely on luck to win a few legs from it. Many bettors are not utilizing the full potential of this gambling type because they don’t have the time to analyze 31 combinations of five-team bets and how much they should back each.

Although our calculator can’t recommend ideal matchups or odds, this tool can help you quickly and accurately determine your estimated profits – for the entire Lucky 31 wager, and for its individual components.

We recommend using this tool for the evaluation of quality Lucky 31 opportunities. By taking a glance at the Alternative Summary Screen, you can reliably ascertain the profitability of your bets.

More importantly, our Lucky 31 Calculator allows you to seamlessly replace selections if you find better ones along the way. The table will automatically update your estimated profits and total earnings whenever any odds or stake amounts are changed.
