How an accumulator pays
An accumulator (acca) is one bet on several selections. Every selection must win, and the odds multiply together. Four selections at 2.0 each give combined odds of 2 × 2 × 2 × 2 = 16.0, so a £5 acca returns £80.
If one selection loses, the whole acca loses. If a selection is void, it's removed and the acca carries on with the rest at lower combined odds.
How acca boosts work
Many bookmakers add a boost to winning accas, shown as a percentage of your winnings. The calculator applies the boost to net winnings (return minus stake), which is how acca boost promotions usually work. A £10 treble at 8.0 has £70 of winnings; a 10% boost adds £7.
At SaviBet, LuckCity and BetBlink, Acca Super Boost starts at 3% for trebles and rises to 100% for 20-fold accas, with every selection at odds of 1.50 or bigger. Check the current terms before you bet.
Things to remember
- More selections means less chance of winning. Each extra leg multiplies the odds because it makes the bet harder to win.
- Boosts have conditions, such as minimum odds per selection, eligible sports and bet types, and maximum boost amounts.
- Cash out offers change the payout of a bet before it settles and usually come with a margin built in.
