How to Calculate Ratings with Put and Share

Reviewed by Calculator Editorial Team

Calculating ratings using the Put and Share method involves determining the overall rating based on individual ratings and their distribution. This guide explains the process step-by-step with a practical calculator.

What is Put and Share?

The Put and Share method is a rating calculation technique used in various fields, including customer satisfaction surveys, product reviews, and performance evaluations. It helps determine an overall rating by considering both the individual ratings and how they are distributed among different categories or criteria.

This method is particularly useful when you need to combine multiple ratings into a single comprehensive score while accounting for the relative importance of different aspects being rated.

How to Calculate Ratings

To calculate ratings using the Put and Share method, follow these steps:

  1. Identify all the individual ratings you want to include in your calculation.
  2. Determine the weight or importance of each rating category.
  3. Multiply each individual rating by its corresponding weight.
  4. Sum all the weighted ratings to get the total weighted score.
  5. Divide the total weighted score by the sum of all weights to get the final rating.

This process ensures that each rating contributes proportionally to the final score based on its importance.

Key Concepts

The Put and Share method is based on the principle of weighted averages. It allows you to combine multiple ratings into a single score while accounting for the relative importance of each component.

The Formula

The formula for calculating ratings using the Put and Share method is:

Final Rating = (Σ (Rating × Weight)) / Σ (Weight)

Where:

  • Rating - The individual rating for each category
  • Weight - The importance or weight assigned to each category

This formula ensures that each rating is proportionally included in the final score based on its weight.

Worked Example

Let's consider a scenario where you have three ratings with different weights:

  • Customer Service: 8 (Weight: 0.4)
  • Product Quality: 9 (Weight: 0.3)
  • Delivery Time: 7 (Weight: 0.3)

Using the Put and Share formula:

Final Rating = [(8 × 0.4) + (9 × 0.3) + (7 × 0.3)] / (0.4 + 0.3 + 0.3)

= [3.2 + 2.7 + 2.1] / 1.0

= 8.0 / 1.0

= 8.0

The final rating is 8.0, which represents the overall performance based on the weighted average of the individual ratings.

FAQ

What is the difference between Put and Share and simple averaging?
Put and Share uses weighted averages, which account for the relative importance of different ratings, while simple averaging treats all ratings equally.
Can I use Put and Share for any type of rating?
Yes, the Put and Share method can be applied to any scenario where you need to combine multiple ratings into a single score, such as customer satisfaction, product reviews, or performance evaluations.
How do I determine the weights for each rating?
Weights can be determined based on the relative importance of each rating category, which may be based on expert opinion, historical data, or stakeholder input.
Is the Put and Share method suitable for all industries?
Yes, the Put and Share method is widely applicable across various industries, including retail, healthcare, education, and manufacturing.
Can I use the Put and Share calculator for more than three ratings?
Yes, the calculator can handle any number of ratings by allowing you to add or remove rating categories as needed.
