The calculator
Wagering is capped at 10x in Britain. Averages assume all stakes on games contributing 100%. A bonus can be lost before wagering is complete.
Reading the results
Total stakes is the bonus times the requirement. Per day divides that by the days allowed. Average cost is what that staking costs over the long run at the chosen RTP.

What it cannot tell you
Whether you will complete the wagering. The average hides a wide spread: some attempts end with nothing, others well ahead. It also assumes every stake counts in full, which is true of most slots and rarely of table games.
