Which calculator should I use?
Different bets need different sums. Use this list to pick the right tool in a few seconds.
- Bet calculator: singles, doubles, trebles, accumulators and full-cover bets such as a Yankee or Heinz. Use it when you want the total return and profit across several selections.
- Each-way calculator: racing and golf bets split into win and place parts. Enter the place fraction and number of places and it shows every outcome.
- Lucky 15 calculator: 15 bets from four selections, with the returns if one, two, three or all four win.
- Free bet calculator: what a free bet is really worth, depending on whether the stake is returned and your odds.
- Odds converter: switch between fractional, decimal and American odds, and see the implied probability and bookmaker margin.
The sums behind the tools
You do not need to calculate anything by hand, but it helps to know what the tools are doing. Here are three examples in euro.
Accumulator. Three selections at decimal odds of 2.00, 1.50 and 3.00 multiply to 9.00. A €10 stake returns €90, which is €80 profit. If any one leg loses, the bet loses.
Each-way. A €5 each-way bet costs €10. At 10/1 with a quarter of the odds for three places, a winner returns €72.50 in total, a placed horse returns €17.50 and a loser returns nothing.
Free bet. A €10 free bet at 3.00 where the stake is not returned pays €20 if it wins, because you only get the profit. That is why free bets are usually worth less than their face value, and why high odds suit them.
Bookmaker margin is the other number to watch. A match priced at 1.80, 3.60 and 4.50 has implied chances of 55.6%, 27.8% and 22.2%, which add up to 105.6%. The extra 5.6% is the margin, and the odds converter shows it for you. To learn the terms, read how betting odds work and bet types explained.
Using the tools safely
Our calculators are a guide only. Settlement rules, Rule 4 deductions, dead heats and bookmaker-specific terms can change what a bet actually pays, so always check the final figure with your bookmaker. A calculator also cannot tell you whether a bet is a good one. It only tells you what happens if it wins.
Set a limit before you bet, and use the figures to understand your risk, not to chase a bigger return. If you need support, call 1800 936 725 or visit gamblingcare.ie.

Frequently asked questions
Are the betting calculators free?
Yes. They are free to use, need no account and work on phone and desktop.
How do I work out my winnings on an accumulator?
Multiply the decimal odds of every selection together, then multiply by your stake. Three selections at 2.00 make 8.00, so a €10 stake returns €80. If any selection loses, the whole bet loses.
How does an each-way bet work?
An each-way bet is two equal bets, one for the selection to win and one for it to place, so it costs double the stake. The place part pays a fraction of the odds, set by the bookmaker for each race.
What is a Lucky 15?
A Lucky 15 is 15 bets on four selections: four singles, six doubles, four trebles and one four-fold accumulator. You need only one winner for a return, though one winner at short odds may return less than your total stake.
Are the calculator results guaranteed?
No. They are a guide. Rule 4 deductions, dead heats, void selections and bookmaker terms can change the final settlement, so check with your bookmaker.
