Singles vs multiples
A single is just one selection, with the best chance of winning. A multiple ties several together, so the odds multiply — four picks at 2.00 pay 16.00 — but every extra leg makes winning less likely.
The simple maths
- Single: Return = Stake x Odds
- Accumulator: multiply all the odds together, then times your stake
Enter odds in any format and the calculator does the rest.
Frequently Asked Questions
What is a single bet?
A single bet is the simplest type of wager — you pick one outcome and place your stake on it. If your selection wins, you receive your stake multiplied by the odds. For example, a $10 bet at decimal odds of 2.50 returns $25 (including your $10 stake), giving you a $15 profit.
What is an accumulator (parlay)?
An accumulator, also called a parlay or multi bet, combines two or more selections into a single wager. All selections must win for the bet to pay out. The odds multiply together, creating potentially large returns from small stakes. For example, three selections at 2.00, 1.80, and 2.50 combine to give total odds of 9.00. The trade-off is higher risk — if even one selection loses, the entire bet loses.
How are accumulator odds calculated?
Accumulator odds are calculated by multiplying the decimal odds of all selections together. For a treble with odds of 1.50, 2.00, and 3.00, the combined odds are 1.50 × 2.00 × 3.00 = 9.00. Your potential return is your stake multiplied by these combined odds. Our Accumulator Calculator handles this automatically for any number of legs.
What is a double bet?
A double is an accumulator with exactly two selections. Both must win for the bet to pay out. The returns from the first selection become the stake for the second. Doubles offer a good balance between risk and potential reward — they are the simplest multi bet and carry less risk than larger accumulators.
What is the difference between each-way and win-only bets?
A win-only bet pays out only if your selection finishes first. An each-way bet is essentially two bets in one — a win bet and a place bet. The place part pays out at reduced odds (typically 1/4 or 1/5 of the win odds) if your selection finishes in a qualifying place position (usually top 2-4, depending on the number of runners and the event). Each-way bets cost double the unit stake.
Should I place accumulators or single bets?
Single bets are statistically better for long-term profitability because each bet is independent and you only need one selection to win. Accumulators offer higher potential payouts but the probability of winning decreases with each added leg. For serious bettors focused on profit, singles and small multiples (doubles, trebles) are generally more sustainable. Accumulators work best as occasional entertainment bets with small stakes.
