Your guess and the reality
What does this problem cost you each month?
Choose one problem, write your guess if you wish, then enter three figures of your own. The calculation runs in your browser, and none of it reaches us.
How we calculated it
Occurrences × minutes ÷ 60 × hourly cost, rounded to the nearest 100. Then the same calculation with each figure a quarter lower, and each a quarter higher. The error in your figures may be greater than that.
