You've backed a selection at a sportsbook. To lock in a result you place an opposing (lay) bet — on an exchange, or by backing the other outcome at a second book.
What it computes
Given your back stake and both prices, it tells you the exact lay stake so your profit is the same whichever way the event goes.
The two modes
- Qualifying bet — minimise the small loss while you unlock a bonus.
- Bonus bet (SNR) — maximise the cash you keep from a free bet (typically ~70%).
The Converter uses this maths automatically and adds a commission input for exchanges.
