How many submissions are there in starter plan?

i am using jot form for my institution.i want to know how many submissions are there in starter plan per form????

The limit is for the whole account, not for each form you have. The free plan is limited to 100 regular or non-payment submissions and 3 payment submissions. If you have payment integration in the form such as Paypal, that will fall under Payment Submissions limit. 

You can check the other limits here https://www.jotform.com/pricing.
