Quick answer
100 free spins at $0.20 on a 96% RTP slot return about $19.20 on average. With no wagering that is what they are worth. With 35x wagering on the winnings, clearing it costs about $26.88 on average, more than the winnings, so most players finish with little or nothing to withdraw. The spins cost nothing, so their value never falls below $0.
Worked example
Formula
Spins worth = spins × spin value
Average winnings = spins worth × RTP
Wagering cost = winnings × wagering × (1 − RTP)
Value after wagering = winnings − wagering cost, never below $0
100 spins × $0.20 = $20 of spins. At 96% RTP they return $19.20 on average. With 35x wagering on that $19.20 you must bet $672, which costs $672 × 4% = $26.88 on average. $19.20 − $26.88 is negative, so the calculator shows $0: in practice the wagering usually uses up the winnings, but you can't lose your own money on the spins themselves.
What makes free spins worth more
- Spin value matters more than the number of spins: 50 spins at $0.20 beat 100 at $0.05.
- No wagering keeps the full average value; 35x wagering on winnings usually wipes it out.
- RTP is fixed by the offer's slot. Check its RTP before you play, as casinos can run lower versions.
- A max cashout caps big wins, which lowers the value further.

Questions
Frequently asked questions
How much are free spins worth?
Multiply the spins by the spin value, then by the slot's RTP. 100 spins at $0.20 on a 96% slot are worth about $19.20 on average, before any wagering.
How does wagering change the value of free spins?
Wagering on the winnings means betting them again, which costs the house edge on every bet. At 35x on a 96% slot, the expected cost is 1.4 times the winnings, so little is usually left.
Why does the calculator need the slot's RTP?
The RTP sets the average return of each spin. A 97% slot returns more than a 94% slot, and it also lowers the cost of any wagering.
Is the estimated value what I will win?
No. It is an average across many players. Any one set of spins can pay nothing or much more.
