Free Bet Calculator
Free · No signup · Works in your browser
See exactly what a free bet returns. Enter the free-bet amount, the decimal odds you'd use it on, and whether the stake is returned. Most free bets are stake-not-returned — you keep the winnings only — which is why they're worth less than the same amount of cash.
Enter the amount, odds and type to see the return.
How it's worked out
A stake-not-returned free bet pays your winnings only:
Return = free-bet amount × (decimal odds − 1).
Example: a $10 SNR free bet at 5.00 returns 10 × (5.00 − 1) = $40 — you keep the $40 profit but not the $10 stake. A cash bet would return $50, so the free bet is worth less. A stake-returned free bet pays amount × odds ($50), like cash.
Use it on higher odds
Because the stake is lost either way, higher odds recover more of a free bet's value — the lost stake is a smaller slice of a bigger win. A $50 SNR free bet on a 1.20 shot returns just $10; the same token at 4.00 returns $150. Read the full picture in our how free bets work guide.
Calculations are exact from the numbers you enter. This tool shows the return if the bet wins; it does not adjust for the probability of winning, and ignores boosts, part-cash-out or void rules.
