Enter the speed of delivery and the maximum time for delivery into the calculator to determine the delivery radius. This calculator helps to estimate the area covered for delivery services.

Delivery Radius Formula

The following formula is used to calculate the delivery radius.

R = S * T

Variables:

  • R is the delivery radius (miles)
  • S is the speed of delivery (miles per hour)
  • T is the maximum time for delivery (hours)

To calculate the delivery radius, multiply the speed of delivery by the maximum time for delivery.

What is a Delivery Radius?

A delivery radius is the maximum distance from a central point that a delivery service will cover. It is typically used by businesses to define the area they can serve within a reasonable time frame, ensuring efficient and timely deliveries. The radius is determined by the speed at which deliveries can be made and the maximum time allocated for a delivery to reach its destination.

How to Calculate Delivery Radius?

The following steps outline how to calculate the Delivery Radius.


  1. First, determine the speed of delivery (S) in miles per hour.
  2. Next, determine the maximum time for delivery (T) in hours.
  3. Next, gather the formula from above = R = S * T.
  4. Finally, calculate the Delivery Radius (R) in miles.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

speed of delivery (S) = 30 miles per hour

maximum time for delivery (T) = 2 hours
