The Google Review Rating Calculator is a powerful tool designed to aggregate customer feedback from Google reviews into a single, meaningful score. This tool computes the average star rating based on the quantity and quality of reviews, offering businesses and service providers a clear insight into their performance as perceived by customers.

## Purpose and Functionality

The primary purpose of this calculator is to quantify the overall customer satisfaction and portray it in a simple rating format. It considers all customer reviews and ratings, from one star to five stars, to compute an overall weighted average. This rating provides businesses with a numeric representation of their customer service, product quality, or overall business efficiency, directly influencing potential customer decisions and business reputation.

## How It Works: Inputs and Formula

The calculator uses a straightforward method involving specific inputs and a mathematical formula to derive an average rating.

## Inputs Required:

**Total number of reviews**: This is the sum of all reviews received.**Individual star ratings**: These are counts of how many 1-star, 2-star, 3-star, 4-star, and 5-star reviews there are.

## Formula:

The calculator employs a weighted average formula, which considers the star value of each review category multiplied by its occurrence:

[ \text{Weighted Average} = \frac{(5 \times N_5) + (4 \times N_4) + (3 \times N_3) + (2 \times N_2) + (1 \times N_1)}{N_1 + N_2 + N_3 + N_4 + N_5} ]

Where:

- ( N_1, N_2, N_3, N_4, N_5 ) are the counts of 1-star to 5-star reviews, respectively.

## Step-by-Step Example:

Suppose a café has received the following review counts:

- 5-star reviews: 150
- 4-star reviews: 60
- 3-star reviews: 30
- 2-star reviews: 10
- 1-star reviews: 5

## Calculation Steps:

**Multiply**each category by its star value:

- ( 5 \times 150 = 750 )
- ( 4 \times 60 = 240 )
- ( 3 \times 30 = 90 )
- ( 2 \times 10 = 20 )
- ( 1 \times 5 = 5 )

**Sum**these values:

- ( 750 + 240 + 90 + 20 + 5 = 1105 )

**Total number of reviews**:

- ( 150 + 60 + 30 + 10 + 5 = 255 )

**Divide**the weighted sum by the total number of reviews to get the average:

- ( \frac{1105}{255} \approx 4.33 )

Thus, the café’s Google review rating would be approximately 4.33 out of 5.
