Pro rata is an adverb or adjective, meaning in proportion.[1] The term is used in many legal and economic contexts. It is sometimes spelled pro-rata, but this is technically a misspelling of the Latin phrase. In North American English this term has been vernacularized to prorated.

Calculation of return premium of a cancelled insurance policy is often done using a cancellation method called pro rata. First a return premium factor is calculated by taking the number of days remaining in the policy period divided by the number of total days of the policy. This factor is then multiplied by the policy premium to arrive at the return premium. Traditionally this has been done manually using a paper wheel calculator. Today it is normally done using an online wheel calculator.[21]

Reading a monthly bill for service that would be prorated.
Determine the daily amount of a monthly charge being prorated by dividing it by the number of days in the cycle (30 is normally used by most systems by default). The resulting number is the daily amount. Example: Based on a 30 day bill cycle and a monthly recurring charge of $30, the daily amount is $1.00 ($30/30 days = $1.00). Determine the number of prorated days. The monthly service charges begin the day service is activated. Example: Service starting on the 20th day of a cycle means there are 10 prorated days. Multiply the daily amount by the number of days being prorated. This gives you the total prorated amount. Example: $1.00 x 10 days = $10.
