## Quick Answer

Calculate the proportional cost of rent, a subscription, or salary for a partial billing cycle. Enter the full rate, period days, and active days.

## Definition

A prorate calculator is a financial utility that determines the proportional charge or payment of a recurring amount over a partial period. It divides the total amount for a full period by the number of days in that period to establish a daily rate, and multiplies it by the number of active or occupied days. It is widely used to calculate partial-month rent, subscription refunds, or mid-period salary adjustments.

## How to Use

1. **Enter full period amount** — Type the total rent, salary, or subscription price for a full billing cycle.
2. **Set total period days** — Provide the number of calendar days in the full billing period (typically 28, 30, or 31).
3. **Enter active days** — Input the number of days you are actually using the service or occupying the space.
4. **View prorated amount** — See the calculated daily rate, the prorated charge, and the remaining refund amount.
