How free bets work — and why a $10 free bet isn't worth $10

Last updated: 2026-07-13 · Gamblerfy editorial team

A "free bet" sounds like free money, but it's the sportsbook equivalent of a bonus with fine print. The single most important thing to know: on most free bets, you don't get the stake back — so a $10 free bet is worth noticeably less than $10 in cash. Here's exactly how they work.

A free bet is a token, not cash

You can't withdraw a free bet. It's a credit you must stake on a qualifying bet. What you can withdraw is whatever it wins — and that's where the catch lives.

"Stake not returned" (SNR) — the default

The vast majority of free bets are stake not returned: if the bet wins, you keep the profit but not the free-bet stake. Compare it to a cash bet:

The formula is simply profit = (odds × stake) − stake. That missing stake is why a $10 free bet is really worth around $7 of value, not $10.

SNR vs SR (stake returned)

The rarer, better version is stake returned (SR): a winning free bet pays profit plus the stake, just like cash. For the same face value, an SR free bet is worth much more — roughly 95% of face value, versus about 70% for SNR. If an offer doesn't say, assume SNR.

Which odds to use it on

Because the stake is lost either way, higher odds waste proportionally less of a free bet. A $50 SNR free bet on a 1.20 favourite returns just $10 profit — you've thrown away most of its value. The same token at 4.00 returns $150. Longer odds recover more of the value, but of course they're less likely to win. This is the opposite of intuition: the "safe" favourite is usually the worst use of a free bet.

How it compares to a casino bonus

A free bet is to sportsbooks what a no-deposit or free-spins bonus is to casinos — headline value that shrinks once you read the terms. The honest way to judge either is by what you can actually keep, which is the whole idea behind our Bonus Value Score. To see the true return of any odds, use the Odds Converter (it shows what a stake returns), and remember the bookmaker's margin is baked into those odds too.

A free bet lowers your cost to bet, but it doesn't change the house edge or make betting profitable on average. Treat it as entertainment value, not a strategy. Read our responsible gambling guide.
