Enter the target date and start date into the calculator to determine the waiting period.

Waiting Period Formula

The following formula is used to calculate the waiting period.

WP = (TD - SD) / DPD


  • WP is the waiting period (days) TD is the target date (date) SD is the start date (date) DPD is the days per division (days)

To calculate the waiting period, subtract the start date from the target date to get the total number of days. Then, divide this number by the days per division. The result is the waiting period in days.

What is a Waiting Period?

A waiting period is a designated amount of time that must pass before certain benefits in an insurance policy or other contractual agreement can begin. It is often used in health insurance policies, where the insured must wait a certain period of time before coverage starts for certain medical conditions or procedures. This is typically used to prevent people from signing up for insurance only when they need immediate coverage. The length of the waiting period can vary depending on the policy or contract.

How to Calculate Waiting Period?

The following steps outline how to calculate the Waiting Period.

  1. First, determine the target date (TD) and start date (SD) in days.
  2. Next, subtract the start date (SD) from the target date (TD) to get the difference in days.
  3. Next, divide the difference in days by the days per division (DPD).
  4. Finally, calculate the Waiting Period (WP).
  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.

Target date (TD) = 2022-10-15

Start date (SD) = 2022-09-25

Days per division (DPD) = 7
