Typically any car designated "total loss" you can recover two amounts -So they paid you back for your coverage while it wasn’t in your possession? If so, that’s impressive!
1) a per diem for loss of use from date the casualty occurred to when it was deemed a total loss, unless you get a rental car in which case the rental offsets the per diem and
2) a car is deemed to have suffered it's damage on the date of loss. When it is totalled the policy is usually considered 'completed' in so far as there is no additional coverage remaining on the vehicle after that date it was totalled. You stop being responsible to pay coverage as of the date of loss, when there was no longer an insurable interest. Basically, if you keep getting charged as of the date of loss, the company refunds the difference between what was owed through date of loss, and whatever you kept paying.
FYI, most insurance companies also report total loss claims to the state and invalidate your registration as of the date of loss, requiring you to re-register and reinsure after completing whatever the applicable inspection/rebuild process is.
