Turnover
The total amount you have wagered over a period, regardless of wins or losses.
Also known as: playthroughaction
The cumulative sum of every bet you have placed, ignoring whether each bet won or lost. If you bet €1 fifty times, your turnover is €50 — even if you’re net up or down.
Wagering requirements are measured in turnover: “40× wagering” means you must generate turnover equal to 40× the bonus.
Expected loss over turnover T at house edge H = T × H. On €4,000 of turnover at 3.5% house edge, expected loss is €140.
Do not confuse turnover with net loss or with deposit. It’s the volume of activity, not the position at the end.
