How to Use This Calculator
Enter the number of free spins from the bonus offer, then the value per spin (check the casino's bonus terms — it's usually listed as something like "spins valued at £0.10 each"). Set the RTP of the game the spins are awarded on, and enter the wagering requirement applied to winnings. Enter 0 for wagering if the offer is wager-free.
The calculator returns three figures: total notional spin value (spins × value), theoretical winnings (spin value × RTP), and realistic expected return after the wagering cost is applied.
Why the Headline Spin Count Is Misleading
Casinos promote free spin offers using the number of spins as the headline figure. "100 free spins" sounds substantial, but without knowing the spin value and wagering requirement, it tells you almost nothing about the actual worth of the offer.
100 spins at £0.10 = £10 in gross spin value. At 96% RTP, that produces £9.60 in expected winnings. Apply a 30x wagering requirement on those winnings: you must now wager £288 on a 96% RTP game. The expected cost of that wagering is 4% × £288 = £11.52 — which exceeds your expected winnings of £9.60. The mathematical expected return from this offer is zero.
This is the standard arithmetic of most free spins offers with wagering attached. The value of claiming them lies in variance — the real possibility of running above expectation — and in the entertainment of the session itself, not in a reliable profit. For offers where the maths genuinely work in your favour, see our free spins listings, including no-deposit free spins that carry no upfront financial commitment.
