Enter the survey word count and the total number of rows into the Survey Length Calculator. The calculator will evaluate the Survey Length. 

Survey Length Formula

The following two example problems outline the steps and information needed to calculate the Survey Length.

SUR = (W/5 + R*1.8) / 60
  • Where SUR is the Survey Length (minutes)
  • W is the survey word count 
  • R is the total number of rows 

To calculate the survey length, divide the survey word count by 5, add this to the product of 1.8 times the number of rows, then divide by 60.

How to Calculate Survey Length?

The following example problems outline how to calculate Survey Length.

Example Problem #1:

  1. First, determine the survey word count.
    • The survey word count is given as: 1000.
  2. Next, determine the total number of rows.
    • The total number of rows is provided as: 50.
  3. Finally, calculate the Survey Length using the equation above: 

SUR = (W/5 + R*1.8) / 60

The values provided above are inserted into the equation below and computed.

SUR = (1000/5 + 50*1.8) / 60 = 4.83 (minutes)


Example Problem #2: 

For this problem, the variables required are provided below:

survey word count = 1000

total number of rows = 30

Test your knowledge using the equation and check your answer with the calculator..

SUR = (W/5 + R*1.8) / 60 = ?
