What is the current submission limit for free jotforms per day/month?

For Free user, the monthly submission limit is 100 or for payment submission it is only 10. You can have a total of 9 Payment submission and 91 normal submission whichever reached the limit first. 

Also, our system reset the monthly limit counter back to 0 every first day of the month. The next reset will be on January 01, 2017.
