A netting calculator combines multiple betting positions across exchanges or bookmakers into a single net position, showing your overall exposure and true profit or loss across all open bets on the same selection. This is essential when you have traded in and out of positions and want to understand your real liability.
Enter each back and lay bet you have placed on the same selection. The calculator nets them against each other and shows your combined position, liability, and expected outcome if the selection wins or loses.
How to Use the Netting Calculator
- 1Add each bet position — for each back or lay bet on the selection, enter the stake, odds, and whether it was a back or lay.
- 2Enter commission where applicable — add your exchange commission rate for any exchange positions.
- 3Read your net position — the calculator shows your combined profit if the selection wins and your profit if it loses, across all positions.
Netting: A Worked Example
Positions on Selection A to Win:
Back €50 @ 3.00 (bookmaker)
Lay €48 @ 3.10 (exchange, 5% commission)
Back €30 @ 2.80 in-play (bookmaker cash out not taken)
Lay €28 @ 2.90 in-play (exchange to reduce exposure)
Net calculation (selection wins)
Back profit: (50 × 3.00 − 50) + (30 × 2.80 − 30) = €100 + €54 = €154
Lay cost: 48 × (3.10−1) × 0.95 = €95.76 + 28 × (2.90−1) × 0.95 = €50.54 = €146.30
Net profit if wins: €7.70
Net calculation (selection loses)
Back losses: −€50 − €30 = −€80. Lay profits: +€48 + €28 = +€76
Net loss if loses: −€4
Common Mistakes When Netting Positions
- ✕Forgetting commission on exchange bets. Lay positions that pay out when the selection loses are not subject to commission, but back positions that win are. Mix these up and your net position is wrong.
- ✕Netting positions across different selections. You can only net positions on the same selection in the same market. Netting across different teams or different events is meaningless.
- ✕Missing in-play bets from the total. Any bet placed during the match on the same selection must be included. Missed positions leave you with an inaccurate liability picture.
Frequently Asked Questions
What is netting in betting?
Netting combines all back and lay positions on the same selection into a single net profit or loss figure. It shows your true overall exposure rather than individual bet results in isolation.
When do I need to net betting positions?
Any time you have traded in and out of a position: opened a lay, partially closed it, added another back, or used in-play cash out partially. The netting calculator gives you the real picture of what you stand to win or lose.
Is netting the same as trading out?
Not exactly. Trading out means placing an additional back or lay to lock in profit or cut losses. Netting is the calculation you use to see your current position before deciding whether to trade out and at what price.
