What does prorated mean?
Prorated describes something that has been divided or calculated in proportion to another factor, most often the duration of time or the amount of service received. For example, a landlord may charge prorated rent when a tenant occupies only part of a month, and an employer may prorate a salary when working hours change. The word is especially associated with billing, contracts, insurance, employment, and property. It conveys fairness and a deliberate adjustment based on a stated ratio rather than an all-or-nothing charge. Although it can occasionally suggest inconvenience or extra calculation, it is generally a neutral, practical term. The related verb is “prorate,” and the noun “proration” names the process or resulting adjusted amount.
Divided or calculated according to a proportion, especially according to the relevant period of time, amount used, or level of service.
"The company offered a prorated refund to customers who cancelled their subscriptions early."
Used especially in financial, contractual, insurance, employment, and property-management contexts.
To calculate or divide a charge, payment, or quantity in proportion to the relevant time, use, or other factor.
"The landlord prorated the first month's rent to account for the apartment being vacant for two weeks."
In the simple past, “prorated” can function as a verb; the related noun is “proration.”
Prorated payments turn one fixed total into a fair share, making them especially common for rentals, subscriptions, memberships, and work that lasts only part of a billing period.

Where does prorated come from?
The word comes from English “prorate,” which was formed from the prefix pro- meaning “in accordance with” or “according to” and the verb “rate,” meaning to assess or classify. “Rate” ultimately derives from Latin rata, the feminine of ratus, meaning “calculated, determined, or settled by rule.” The Latin root ratio, a calculation or proportion, also underlies related words such as “ration” and “rational.” The adjective “prorated” developed as the present participle of “prorate” and came to describe an amount or charge calculated proportionally.
