Bonus Bet (Free Bet)

A bonus bet, often called a free bet, is a voucher a bookmaker issues instead of cash. You use it exactly like real money to back a selection, but the settlement works differently: if the bet wins, you’re paid the winnings only — the stake evaporates rather than being returned to your balance. Back a €20 bonus bet at 3.00 and you collect €40, not the €60 you’d get from a genuine €20 cash stake at the same price.

That single mechanical difference — stake withheld on settlement — is what separates a bonus bet from actual bankroll, and it’s why bonus bets are worth noticeably less than their face value. A €20 note is worth €20 whatever you do with it. A €20 bonus bet is only worth something once it wins, and even then it’s worth less than €20 cash would have earned you on the same bet.

Bookmakers hand these out for all sorts of reasons: a welcome offer for new accounts, a “second chance” credit if your first real-money bet loses, a loyalty reward, or a nudge to try a market like acca insurance. The terms attached — minimum odds, expiry windows, which sports qualify, whether the bonus bet stake counts if you cash out early — vary enormously between operators and matter as much as the amount itself.

Example

Say Bayer Leverkusen host Union Berlin and you’re given a €30 bonus bet as a deposit-match reward. Leverkusen to win is priced at 1.72 (roughly 5/7 fractional). You place the full €30 bonus bet on that.

Leverkusen win. The bet returns 30 × 1.72 = €51.60 in total winnings terms if it were cash — but because it’s a bonus bet, the stake of €30 is stripped out before you’re paid. You receive €51.60 − €30 = €21.60, credited as withdrawable cash.

Now compare that with a friend who staked €30 of their own money on the same match at the same price. Cash return: €51.60, of which €30 is just their stake back and €21.60 is genuine profit — same profit figure, but they also keep their original €30. You don’t, because it was never really yours.

This is the part people miss: the value of a bonus bet is not its face amount, it’s roughly (odds − 1) / odds of the face amount, assuming the odds are fair. At 1.72, that’s 0.72/1.72 ≈ 42% — so a €30 bonus bet used at those odds is worth about €12.60 in expected terms, not €30. Push the odds higher and that ratio improves. The same €30 bonus bet used on a selection at 4.00 would return €120 total, paying out €90 after the stake is stripped — an extraction rate of 75% instead of 42%. Bonus bets get more valuable the longer the odds, which is the opposite of how most punters intuitively use them.

Key Points

• The stake is never yours: whatever the outcome, you don’t get the bonus bet amount back. Budget for it as “potential winnings only,” not as spendable bankroll.
• Higher odds extract more value: because the stake is deducted regardless of price, a bonus bet placed at 4.50 returns a far higher percentage of its face value than the same bonus bet placed at 1.50. If you have a choice of selections, lean toward longer, still-legitimate prices rather than odds-on shouts.
• Check the minimum odds clause: most operators require a minimum price (commonly around 1.50–2.00 decimal, or higher) for the bonus bet to qualify at all. Placing it below that threshold can void the offer entirely.
• Expiry dates are real deadlines: bonus bets typically lapse within 7–30 days of issue. An unused bonus bet is worth precisely nothing, so treat the expiry like a bill due date, not a soft suggestion.
• One bonus bet, one selection is usually cleanest: splitting a bonus bet across multiple smaller bets, where allowed, dilutes the odds advantage described above and adds complexity for little gain — unless you’re deliberately hedging.
• Don’t chase break-even with it: because a bonus bet only pays out winnings, using it to “get back” a previous loss doesn’t restore your original stake — it only ever adds partial value on top. Treat it as a discount on future betting, not as lost money recovered.
