How to use the free bet calculator
- Enter the free bet amount, the face value of the free bet.
- Pick fractional, decimal or American odds and enter the price.
- Choose SNR (stake not returned) for a standard UK free bet, or SR (stake returned) to compare.
- Add more legs if you want to treat the free bet as an accumulator.
- Mark the result as Win, Lose or Void, and read the returns and profit.
Stake not returned vs stake returned
Most bookmaker free bets are stake not returned (SNR). The free bet stake is not paid back with your winnings, so you only receive the profit. A £10 free bet at 5/1 pays £50, not £60. With stake returned (SR), which is rarer, the same bet pays £60.
| Free bet type | £10 at 5/1, wins | Profit |
|---|---|---|
| SNR (stake not returned) | £50.00 | £50.00 |
| SR (stake returned) | £60.00 | £50.00 |
Under both types, the profit is £50. The difference is whether the £10 stake is included in the amount paid back. A losing free bet returns £0 under both and costs you nothing, because you did not pay the stake.
Free bet worked examples
- SNR single, wins: £10 free bet at 5/1 returns £50.00.
- SR single, wins: £10 free bet at 5/1 returns £60.00.
- Loser: £0.00 returns in both modes.
- Two-leg accumulator: a £10 free bet on a 2/1 and a 3/1 accumulator has combined decimal odds of 12.00. With both legs winning, SNR returns £110.00 and SR returns £120.00.
- Accumulator with a void leg: if the 3/1 leg is void, the bet settles as a single on the 2/1 at 3.00. SNR returns £20.00 and SR returns £30.00.
- Another single: £25 free bet at 7/2 returns £87.50 under SNR and £112.50 under SR.
What this free bet calculator is not
This is a bookmaker returns calculator. It shows what a free bet pays. It does not lay off a qualifying bet or work out a hedge, so it is not a matched betting calculator.

Free bet calculator FAQs
Where can I find a free bet calculator in the UK?
You are on one. Enter your free bet amount, the odds and the type of free bet, and it shows what the bookmaker would pay.
How do I calculate free bet winnings?
For a standard free bet, multiply the free bet by the odds minus one. A £10 free bet at decimal 6.00 (5/1) pays £10 × 5 = £50.
What is the difference between SNR and SR?
SNR means stake not returned: you only get the winnings. SR means stake returned: the stake is paid back as well.
Does a losing free bet return anything?
No. A losing free bet returns £0, and you have lost none of your own money.
Does this work for accumulators?
Yes. Add the legs and the calculator combines the odds. A void leg is dropped and the bet is settled on the remaining legs.
