How to use this calculator
How to use the Matched Betting Qualifier Calculator
Use this matched betting qualifier calculator to estimate your qualifying loss before placing your first bookmaker and exchange bets. A qualifier is your initial bet to unlock an offer, Freebet SNR means stake not returned, and Freebet SR means stake returned with winnings.
- Qualifier = first bet placed mainly to qualify for a bonus, usually with a controlled small loss.
- Freebet SNR = stake not returned, so only winnings are paid on the free bet.
- Freebet SR = stake returned, so winnings include the returned free bet stake.
- Enter your bookmaker back stake and back odds.
- Enter exchange lay odds and lay commission.
- Set back commission if your bookmaker market charges commission.
- Use the advanced underlay or overlay slider only if you want a non-even hedge.
- Check both outcomes and focus on the expected qualifying loss amount.
This qualifier calculator is designed for UK matched betting workflows and helps compare back and lay results, lay liability, and expected qualifying loss quickly.
