Estimate how long your money lasts on a slot. The "expected" figure assumes average results; the realistic figure accounts for volatility.
*Rough estimate of the median number of spins before a bankroll runs out, based on typical win distributions for each volatility class. Real sessions vary enormously.
Average cost per spin = stake × (1 − RTP). Expected spins = bankroll ÷ cost per spin. But because wins come in uneven bursts, most sessions end much sooner than the average suggests — especially on high-volatility games. Read more in our bankroll maths guide.
