If you were involved in an accident where you were at fault, and the payout from your insurance company was over $1,000 you will see a surcharge on your next policy renewal. There is no "clear cut" amount or formula to know how much exactly your policy will increase. If this was your one and only accident inside of three years, you can expect anywhere from a 15% to 20% increase on your rates.
Again, there are many variables that go into your overall rate, so it's not uncommon for the increase to be below those numbers, or more. This should give you an idea on how much your insurance will increase after an at fault accident.
