Accumulator calculator
Add your legs, set a stake, and see your combined acca odds, total return and, the part most calculators skip, the true probability that every selection actually lands.
How accumulator odds work
An accumulator (acca) rolls several selections into one bet. The combined odds are the product of each leg's decimal odds: multiply them together. Four legs at 1.50, 2.00, 1.80 and 2.50 give 1.50 × 2.00 × 1.80 × 2.50 = 13.50, so a £10 stake returns £135.
Why accas are high-variance: every leg has to win. If each leg also has its own win probability, the chance the whole acca lands is the product of those probabilities, and that number falls fast. Four legs at 60% each is only 0.6⁴ ≈ 13%. The odds look big because the true chance is small.
Knowing the true combined chance is the edge. Compare the implied probability of the combined odds (1 ÷ combined odds) against the real product of your leg probabilities. If your honest probability is higher than the bookmaker's implied one, there's value; if it's lower, you're paying for the dream.

The singles we'd pick ourselves, with the research and the price behind each one
- The daily singles. Each one cleared three checks: the line landed in at least 9 of the two sides' last 12 games, a UK price of 1.35 or more, and our model's number clears what the price needs. Usually 0 to 5 a day, one unit each.
- The case for each, put together. The last 12 against what the price needs, who is missing, the head to head, and the best price at a UK bookmaker, in one place.
- The desk's card on every fixture it covers. Its verdict, every market graded, and the reason written down. And tomorrow's singles the night before.
