How this calculator works
Paris couverts is a technique that uses a back bet (placed at a bookmaker) and a lay bet (placed at a betting exchange) to cover both outcomes of a marché, eliminating exposure to loss and extracting value from free bets and bonuses.
The optimal lay stake is calculated to make profits equal in both scenarios. For a qualifying bet (argent réel), the formula is: lay stake = (back stake x back cotes) / (lay cotes - commission rate). For a free bet where the stake is not returned: lay stake = (back stake x (back cotes - 1)) / (lay cotes - commission rate).
The lay liability is the amount you must hold in your exchange account to cover the lay bet: liability = lay stake x (lay cotes - 1). This is not lost money; it is returned if the lay wins.
For qualifying bets, you typically incur a small loss because back cotes and lay cotes are rarely identical and exchange commission applies. This qualifying loss is the cost of unlocking a free bet.
For free bets (stake not returned, SNR), the calculation changes because you are not risking your own stake on the back side. The net profit from a free bet is typically 70-90% of the face value, deen attente on how closely back and lay cotes match and the level of exchange commission. A free bet of 20 units at close cotes with 5% commission typically extracts 14-17 units of guaranteed profit.
Exchange commission reduces the effective lay cotes. A 5% commission on a lay at 3.10 means the real lay cotes are 3.10 - (3.10 - 1) x 0.05 = 3.10 - 0.105 = 2.995. The calculator applies commission to all lay winnings automatically.
Closer back and lay cotes produce smaller qualifying losses. Always cherche lay cotes within 0.10-0.15 decimal of the back price to keep qualifying losses manageable.

FAQ
What is a free bet SNR?
SNR stands for "stake not returned". When a free bet wins, you receive only the winnings, not the original stake amount. This is the most common type of free bet offered by bookmakers, notamment 1win.
What exchange commission rate should I use?
Major exchanges typically charge 2-5% commission on net winnings per marché. Check your specific exchange account; premium members sometimes pay lower rates. The default in this calculator is 5%.
Why do I sometimes make a loss on a qualifying bet?
Qualifying losses arise when back and lay cotes differ. The lay cotes are usually slightly higher because exchanges charge commission, creating a gap. This small loss is the cost of qualifying for a free bet or bonus.
How do I find the best lay cotes?
Compare cotes at major betting exchanges. Higher liquidity marchés (e.g. top football leagues) typically have tighter back-to-lay spreads, reducing qualifying losses.
Is paris couverts risk-free?
When executed correctly with matching back and lay bets, paris couverts involves minimal financial risk from the bet outcome itself. The main risks are operator error (wrong stake or cotes entered), bookmaker bonus term changes, and account restrictions from identified matched bettors.
