How to Use the bet365 Free Bet Calculator - Lucky 15, Yankee, Acca & More
Short Summary
The bet365 Free Bet Calculator lets you work out your potential returns on any bet type — Singles, Accumulators, Lucky 15s, Yankees, Patents and more — before you place a penny. Enter your odds and stake, and it instantly shows your total return and profit. It's one of the most useful tools on the site, especially for complex multi-selection bets where the maths isn't obvious. This guide explains how to use it and covers every bet type the calculator supports.
Why Use a Bet Calculator Before You Bet?
Most bettors place bets without knowing exactly what they'll win. They have a rough idea, but the precise return — especially on accumulators, each way bets or complex bets like Lucky 15s — isn't always clear until after the results come in.
The bet calculator fixes this. Before committing your stake, you can:
- Check if the potential return is worth the stake
- Compare what a £5 each way bet returns versus a £5 win-only bet
- Understand exactly how much you'd win if 4 of your 5 acca legs land
- Work out the total stake on a Lucky 15 before you accidentally commit 15x your intended unit stake
- Set a realistic target return and work backwards to find the right stake
It takes 30 seconds and removes all guesswork.
How to Use the bet365 Bet Calculator
- Go to the Bet Calculator on bet365 — find it via the footer, the site features section, or search "bet calculator" in the site.
- Select your bet type — Accumulator, Single, or click "More..." for all other bet types.
- Add your selections — For each leg, choose "To Win" or "Each Way" from the dropdown, then enter the odds. Click "+1 selection" to add more legs.
- Enter your stake — This is your unit stake. For multi-bet types like Lucky 15, the calculator multiplies this by the number of bets automatically.
- Tick E/W if betting each way — The calculator doubles your stake and calculates both the win and place returns.
- Read your results — The calculator shows Total Stake, To Return and Profit instantly.
Odds format: Enter odds in fractional format (e.g. 5/1, 9/4, Evens) or decimal (e.g. 6.00, 3.25, 2.00). The calculator handles both.
Every Bet Type Explained
The bet365 calculator covers Singles and Accumulators directly, plus an extensive range of bet types under "More...". Here's what each one means and when to use it.
Single
One selection. If it wins, you win. The simplest bet type.
Example: £10 on Arsenal to win at 2/1 → Returns £30 (£20 profit + £10 stake)
Double
Two selections combined. Both must win. Your winnings from the first selection roll onto the second automatically.
Example: £10 double on Arsenal (2/1) and Liverpool (3/1). Both win → £10 × 3 × 4 = £120 return (£110 profit)
Treble
Three selections, all must win. Returns roll through all three legs.
Fourfold, Fivefold, Sixfold, Sevenfold, Eightfold
Named accumulators for a specific number of selections — all must win. The bet365 calculator lists these individually (Fourfold = 4 selections, up to Eightfold = 8 selections), each as a single combined bet. Returns multiply through every leg. One loser ends the bet.
Trixie
3 selections → 4 bets (3 doubles + 1 treble). Unlike a straight treble, you don't need all three to win — if two win, you get a return from the double.
Total stake at £1/unit = £4
Patent
3 selections → 7 bets (3 singles + 3 doubles + 1 treble). The safest multi-bet for 3 selections — even one winner returns something.
Total stake at £1/unit = £7
Yankee
4 selections → 11 bets (6 doubles + 4 trebles + 1 fourfold). No singles — need at least 2 winners for a return.
Total stake at £1/unit = £11
Super Yankee (Canadian)
5 selections → 26 bets (10 doubles + 10 trebles + 5 fourfolds + 1 fivefold). The 5-selection equivalent of a Yankee — no singles, so 2 winners minimum needed for any return. Also known as a Canadian. Good for bettors who have 5 fancied selections and want full multi-coverage without paying for singles.
Total stake at £1/unit = £26
Lucky 15
4 selections → 15 bets (4 singles + 6 doubles + 4 trebles + 1 fourfold). The most popular full-cover multiple for horse racing. Even one winner returns something thanks to the singles.
Total stake at £1/unit = £15
Note: Many bookmakers offer a bonus on Lucky 15s for all 4 winners. Check any active bet365 promotions when placing.
Lucky 31
5 selections → 31 bets (5 singles + 10 doubles + 10 trebles + 5 fourfolds + 1 fivefold). Full coverage of 5 selections.
Total stake at £1/unit = £31
Lucky 63
6 selections → 63 bets (6 singles + 15 doubles + 20 trebles + 15 fourfolds + 6 fivefolds + 1 sixfold). Full coverage of 6 selections. One of the most popular multiple bets for Saturday horse racing cards.
Total stake at £1/unit = £63
Heinz
6 selections → 57 bets (no singles). Like a Lucky 63 but without the singles — lower total stake but need at least 2 winners for any return. Named after the 57 varieties.
Total stake at £1/unit = £57
Super Heinz
7 selections → 120 bets (no singles). All combinations of 7 selections except singles. Serious stakes involved — the calculator is essential before placing.
Total stake at £1/unit = £120
Goliath
8 selections → 247 bets (no singles). At £0.10/unit that's £24.70 — at £1/unit you're in for £247. Always use the calculator first.
Total stake at £1/unit = £247
Super Heinz with Singles
7 selections → 127 bets (Super Heinz's 120 bets + 7 singles). Adds singles to the standard Super Heinz, so even a single winner returns something. The safest version for 7 selections but the most expensive — £127 at £1/unit.
Total stake at £1/unit = £127
Goliath with Singles
8 selections → 255 bets (Goliath's 247 bets + 8 singles). The largest bet type on the calculator. Adds singles to the standard Goliath for full coverage — even one winner returns something. At £0.10/unit the total stake is £25.50; at £1/unit it's £255. The calculator is absolutely essential before placing this.
Total stake at £1/unit = £255

Each Way Bets — How the Calculator Handles Them
Tick the E/W box in the calculator and the maths changes significantly. An each way bet is two separate bets of equal stake — win + place. The calculator automatically:
- Doubles your total stake (e.g. £5 E/W = £10 total)
- Calculates the win part at full odds if your selection wins
- Calculates the place part at the stated fraction (typically 1/4 or 1/5 of win odds) if your selection places
- Shows the combined return
Each leg also has a dropdown to mark it as "To Win", "Each Way" or "Non Runner" — useful for mid-race or post-race calculations to see what you'll receive after a non-runner reduces your acca or Lucky 15.
Each Way Calculator Example
£5 E/W on a horse at 10/1, standard 1/4 odds, 3 places:
- Win part: £5 × 10/1 = £50 winnings + £5 stake = £55
- Place part: £5 × (10/1 ÷ 4) = £5 × 2.5/1 = £12.50 winnings + £5 stake = £17.50
- Total if wins: £72.50 return (£62.50 profit)
- Total if places only: £17.50 return (£7.50 profit on £10 total stake)
The calculator does all of this instantly — especially useful on complex each way multiples like a Lucky 15 E/W where calculating manually would take forever.
Real-World Examples
Example 1: 5-fold Accumulator
You have five selections at 2/1, 3/1, 5/2, 6/4 and 11/10. What does a £10 acca return if all five win?
Enter each set of odds into the calculator, select Accumulator, set stake to £10 → result shows immediately. Without the calculator: 3 × 4 × 3.5 × 2.5 × 2.1 × £10 = £882 — but one wrong decimal and your mental maths is off. The calculator removes that risk.
Example 2: Lucky 15 at Saturday Racing
You have four horse racing selections. At £1/unit your Lucky 15 costs £15 total. You want to know what you'd win if 3 of the 4 land. Enter the four sets of odds, select Lucky 15, stake £1 — the calculator shows exactly what the 3-winner and 4-winner scenarios return, including the bonuses if bet365 is running a Lucky 15 promotion that day.
Example 3: Checking If a Bet Has Value
You're considering a 4/1 shot each way at £10. Total stake: £20. Is it worth it? Use the calculator:
- Wins: £10 × 4/1 = £40 + stake = £50 (win), plus place return of £10 × 1/1 = £10 + stake = £20 (place) → £70 total
- Places only: £20 back from place part (breaks even on place, loses win stake)
Now you can make an informed decision rather than guessing.
Tips for Getting the Most Out of the Bet Calculator
- Always check your Lucky 15/31/63 total stake before placing. The total stake multiplies fast — at £2/unit, a Lucky 63 costs £126. Use the calculator to confirm before you hit confirm on the bet slip.
- Use the Non Runner option to calculate returns mid-race. If you have a Lucky 15 running and one horse is a late non-runner, switch that selection to "Non Runner" in the calculator to instantly see your revised potential returns.
- Compare bet types side by side. Use the calculator twice — once for a Trixie, once for a Patent — to compare how much more the Patent costs versus the extra security of the singles returning something.
- Check each way vs win-only before committing. On a well-fancied favourite at 7/4, is an each way bet actually worth the double stake? The calculator tells you in seconds.
- Work backwards from a target return. Want to win £500 on a three-fold treble? Enter the odds and adjust the stake until the return hits your target.

Final Verdict
The bet365 Free Bet Calculator is genuinely one of the most underused tools on the site. Most bettors only reach for it when they're confused about a big multi-bet — but it's just as valuable for everyday decisions: checking each way returns, comparing bet types, confirming your Lucky 15 total stake before it doubles what you intended. Make it a habit to run your bet through the calculator before placing, particularly on anything more complex than a single or double. It takes 30 seconds and removes every element of uncertainty about what you're risking and what you're chasing.
