This free online calculator calculates the stakes for backing and laying the same selection for a level profit after commission. It supports both same-market and cross-market calculations and shows you exactly how much commission is payable on each bet.

A popup version is also provided for your convenience.

1. Enter both prices

The Back Price must be higher than the Lay Price to ensure a guaranteed profit.
Enter prices in decimal, fraction or US format.
Fractions and US prices are autoconverted into exchange-friendly decimal prices.

2. Enter one stake

Enter the Back Stake, Lay Stake or Total Stake, depending on the bet type.
Enter the Lay Stake for trades on a price rise.
Enter the Back Stake for trades on a price fall.
If you enter two stakes, the first value is cancelled (reset to 0.00).

3. Specify whether the bets are same-market or cross-market

Select Back and Lay selection on same exchange for same-market bets.
Clear Back and Lay selection on same exchange for cross-market bets.
This setting determines whether commmission is applied to the individual Back Bet Profit and Lay Bet Profit (cross-market) or to the overall Market Profit (same-market).

4. Enter the applicable commission rate(s)

The default Commission for same-market bets and cross-market Lay bets is 5.00%.

5. Press Calculate to view results

View the stake(s) required to win the same Net Profit whatever the result.
Back Bet Profit and Lay Bet Profit show the profits from each of the two bets.
Commission Paid shows the commission deducted by the betting exchange.
Yield is obtained by dividing the Net Profit by the Total Stake and indicates the profitability of the trade or arb.
