Enter the number of promoters and detractors, and the total number of respondents into the calculator to determine the Total Net Promoter Score.

Tnps (Total Net Promoter Score) Formula

The following formula is used to calculate the Total Net Promoter Score (Tnps).

Tnps = ((P - D) / R) * 100

Variables:

  • Tnps is the Total Net Promoter Score (%)
  • P is the number of promoters (people who would highly recommend the product or service)
  • D is the number of detractors (people who would not recommend the product or service)
  • R is the total number of respondents

To calculate the Total Net Promoter Score, subtract the number of detractors from the number of promoters. Divide the result by the total number of respondents. Multiply the quotient by 100 to get the Total Net Promoter Score as a percentage.

What is a Tnps (Total Net Promoter Score)?

The Total Net Promoter Score (TNPS) is a metric used to measure customer loyalty and satisfaction. It is calculated by subtracting the percentage of detractors (customers who would not recommend a company) from the percentage of promoters (customers who would recommend a company). The score ranges from -100 to 100, with a higher score indicating a higher level of customer satisfaction and loyalty.

How to Calculate Tnps (Total Net Promoter Score)?

The following steps outline how to calculate the Total Net Promoter Score (Tnps).


  1. First, determine the number of promoters (P).
  2. Next, determine the number of detractors (D).
  3. Next, determine the total number of respondents (R).
  4. Next, use the formula Tnps = ((P – D) / R) * 100 to calculate the Total Net Promoter Score.
  5. Finally, calculate the Tnps by inserting the values of P, D, and R into the formula and performing the calculations.

Example Problem:

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

Number of promoters (P) = 150

Number of detractors (D) = 50

Total number of respondents (R) = 500
