The two proration methods commonly used are the 365-day method and the 30-day month method. The 365-day method prorates amounts based on the actual number of days in a year. The 30-day month method, on the other hand, assumes each month has 30 days, making it simpler for monthly or quarterly calculations in contexts like real estate or insurance.
