Car insurance increase?

I’m a 22 year old who is currently covered under Allstate. I was paying $950 Per 6 months until i rear ended someone this past summer. I did not recieve an increase on my next policy but the most recent one has gone up $700 per six months. I am now paying 1650 every 3 months. I have been insured with them for 3 years, i did minor damage to their car, about 4k worth to mine, there were no injuries, i did not receive a ticket with any points. It is a 2007 chevy cobalt that i own with approx 30k miles. I have had my license since i was 17 and have not been in any accidents or received any tickets prior to this accident. Does this sound about how much my insurance should go up for one accident?
