To Prorate means to divide or distribute a cost, benefit, or amount proportionally based on time, usage, or another measurable factor. This method ensures that each party or period receives or pays a fair share relative to their portion of the whole. Proration is commonly used in various financial and contractual contexts, such as rent and utilities, salaries and wages, insurance premiums, dividends and interest, subscription services, and more.

Proration ensures fairness and accuracy in financial transactions, especially when full-period charges or benefits do not apply.
