Oddsmart’s Accumulator Calculator optimises your matched-betting strategy by delivering fast, accurate projections for up to ten-leg accumulators, each-way bets, Rule 4 deductions and special promotions.
Simply enter your unit stake (e.g. £10), bet type (single through tenfold), odds format (fractional, decimal or American) and whether it’s each-way or win-only.
Then configure each leg with a selection name, back odds, expected result (Win, Place, Dead Heat, Lost or Void) and, if needed, a Rule 4 deduction percentage.
The calculator automatically converts all odds to decimal, applies dead-heat and Rule 4 adjustments, and computes effective odds per leg. Instantly, you receive your total stake, total return and total profit.
A scenario breakdown table illustrates your exposure at every possible failure point—“Leg 1 loses,” “Leg 2 loses,” … through “All legs win”—so you can optimise lay stakes, minimise risk and plan around free bets or promotional offers.
Bonus features include handling bookmaker incentives like all-winner bonuses, one-loser insurance and one-winner consolations.
Whether you’re qualifying for a free bet, hedging liability or planning your next acca, Oddsmart’s calculator ensures you know your worst-case loss and best-case profit before you stake a penny.
