Frequently Asked Questions

Proration is the allocation of a total amount over a partial period, often used for rent, subscriptions, or salaries when service is not used for the full period.

Divide the total amount by the total number of periods, then multiply by the number of periods used. For example, if rent is $1200 for 30 days and you stay 10 days, the prorated amount is ($1200/30)*10 = $400.

Yes, the calculator supports days, weeks, and months. Ensure you use consistent units for total and used periods.
