When calculating prorated amounts, you may need to use different words depending on the context. Synonyms for prorated include proportionate, divided, adjusted, split, distributed, and allocated. These words imply that a certain value is being divided into equal parts according to a certain criterion, such as time or usage. For example, if you're calculating a prorated rent amount, you could say that the rent is proportionate to the number of days in the month or that it's adjusted based on the move-in date. In other cases, the word prorated may be the most precise way to describe the situation, but using synonymous terms can help clarify the meaning for your audience.
