Free Bet Calculator Ireland
Almost every Irish bookmaker welcome offer is “Stake Not Returned” (SNR) — meaning if your free bet wins, you keep the profit but not the original free bet amount. This calculator shows exactly what a free bet is worth in real cash.

How Free Bet Value is Calculated
A free bet’s real cash value depends on the odds you use it at. At longer odds, the profit is bigger but less likely to land. The formula below calculates the expected value — what the free bet is worth on average, factoring in the probability of winning:
SNR Free Bet Value
Cash Value = Free Bet × (Decimal Odds − 1) / Decimal Odds
Example: €10 free bet at odds 3.00
Cash Value = €10 × (3.00 − 1) / 3.00 = €10 × 2/3 = €6.67
SR Free Bet Value (full odds)
Cash Value = Free Bet × Decimal Odds / Decimal Odds = Free Bet amount
Cash Value = Free Bet × (Decimal Odds − 1) / Decimal Odds
Example: €10 free bet at odds 3.00
Cash Value = €10 × (3.00 − 1) / 3.00 = €10 × 2/3 = €6.67
SR Free Bet Value (full odds)
Cash Value = Free Bet × Decimal Odds / Decimal Odds = Free Bet amount
Why odds matter: At odds 2.00 (evens), a €10 SNR free bet is worth €5. At odds 4.00, it’s worth €7.50. The higher the odds, the higher the potential return — but also the lower the probability of winning. For matched betting, odds around 3.00–5.00 are typically the sweet spot to extract value while keeping risk manageable.
