Short Rate Calculation Information:

Earned premium is the amount you will owe the insurance company when you cancel your policy.

Don't forget to include fees into this total to get the final amount owed to the insurance company.

If you cancel your policy mid-term, you will owe the short rate calculation amount determined by the short rate calculator.

If your policy cancels for non-payment, you will owe the pro rata calculation amount determined by the calculator.
