To calculate the pro rata rate, first determine the total amount to be allocated. Then, decide the basis for allocation, such as time, quantity, or usage. Finally, apply the formula: Pro Rata Rate = (Individual Part / Total Basis) * Total Amount. For example, if dividing a $1000 cost over 10 days and you need the rate for 3 days: Pro Rata Rate = (3/10) * $1000 = $300.
