You can view the current Monthly Usage in the account Monthly Usage page http://www.jotform.com/myaccount/usage
But please take note that, since the monthly submissions/usage is being reset every 1st Day of the current month, the current view is for the current month only.
You will not see the past month usage view on this page.
In your case, perhaps you can just use your form submissions as the basis to know your previous month submission.
You can try using the Submission History Chart to have better viewer/chart.

Hope this help. Please inform us if you need further assistance.
