Accumulator Calculator, Work Out Your Bet Returns
Use our accumulator calculator to work out your potential returns on multi-selection bets, where odds multiply across every leg.
This accumulator calculator works out the return on a betting accumulator, or acca, of any size from a double to a 20-fold. Add a selection for each leg, type the odds, mark the results and the return updates as you type. It is for betting accumulators only, not hydraulic or savings ones.
An accumulator combines two or more selections into one bet. Every selection must win. The returns multiply: stake times the decimal odds of every leg. A £5 four-fold at evens on each leg pays £80.
This accumulator calculator lets you work out the returns instantly. Simply enter your selections, their odds, and your stake, the calculator multiplies the odds together and shows you the potential return and profit if every selection wins.

Turn each price into decimal odds by dividing the fraction and adding one, so 2/1 is 3.00 and 5/2 is 3.50. Multiply them all together, then multiply by the stake. That is the return. Profit is the return minus the stake. The bigger the acca, the faster the number grows, and the more legs that have to win.
Football accumulator calculator
Football accas work the same way. Type the odds for each match result, mark each leg Won or Lost, and the tool settles it. A postponed match is a void leg: mark it NR and the acca drops down one fold, so a five-fold becomes a four-fold on the legs that stood.
Each way accumulator calculator
Switch on each way and every leg gets a win part and a place part. The win acca needs every horse to win. The place acca pays if every horse at least places, at the place fraction for each race. Set the place terms per selection. The stake doubles, because there are two accas.
What happens if one leg is void or a non-runner?
Mark it NR. That leg is settled at 1/1, so it neither adds to nor takes from the return, and the acca is paid on the remaining legs. A lost leg loses the whole acca. There is no consolation on a straight accumulator, which is why some people prefer a Lucky 15.
Worked example: A £5 four-fold
£5.00 on 1. 2/1 won, 2. 1/1 won, 3. 5/2 won, 4. 3/1 won. Total stake £5.00.
| Bet | Bets | Stake | Return |
|---|---|---|---|
| 4-fold | 1 | £5.00 | £420.00 |
| Total | 1 | £5.00 | £420.00 |
Return £420.00 on £5.00 staked, a profit of £415.00. These are the figures the tool above opens with.
Built for a phone, not a desk
Most bet calculators are a desktop form buried in a page of adverts and articles. This one is one screen, made for a phone in the bookies or on the sofa. Tap the bets you want to place and they light up. Mark each pick Won, Lost or NR before you type a price, so losers need no odds at all. The total sits at the bottom of the screen the whole time. Every calculator on this site is the same tool with a different bet loaded, so there is nothing new to learn from page to page.
