I've added Estimated cost and how long your cron will be kept executing at the Control Panel.
For example, I have three cron jobs daily, one cron job every 6 hours, one cron job every 30 minutes, and here's the estimation:
You have 5 cron jobs. Estimated cost: $0.20075 / year. Your cron will be executed in 4454 years 2 months 13 days 18 hours.
So, if I make a payment of $1, it's enough to launch my cron for 5 years :D
