Enter your stake and the price you took, mark the result, and see the return and the profit. It handles singles, accumulators, full-cover bets and each-way, with free bets, Rule 4 deductions and exchange commission if you need them.
Every return starts from the same sum: your stake multiplied by the decimal price. A $20 single at 3.75 returns $75 — $55 profit and your $20 stake back. Fractional (11/4) and American (+275) prices are converted to decimal first, which the calculator does as you type, so you can mix formats across legs without thinking about it.
For an accumulator the leg prices multiply together before the stake is applied: four legs at 1.83, 1.90, 2.40 and 2.10 give a combined 17.53, so $20 returns $350.63. A void leg is priced at 1.00, which means it drops out and the rest of the bet stands.
Trixies, Yankees, Lucky 15s and the rest are just many small bets rolled into one. A Lucky 15 is four selections combined into 15 bets — four singles, six doubles, four trebles and a fourfold — so a $1 Lucky 15 costs $15 and pays out as long as one selection wins. The calculator shows exactly which lines paid and what each contributed.
Turn on Each-way under More options to split the bet into a win half and a place half at your chosen place terms (1/5, 1/4). Rule 4 reduces winnings when a rival is withdrawn, Free bet removes the stake from the return, and Commission nets a percentage off winnings on the exchange — all optional, all applied instantly.
