Basic maths question - calculating Trustpilot score.

SideWinder · 10 Aug 2021 at 17:30

Hello!

I want to calculate how many more 5* stars review a company will need to go from 4.6 to 4.7 on Trustpilot. It would be great to know how many would be required to hit 4.8 and 4.9 too.

4.6 currently:

270 reviews
5 star = 223
4 star = 19
3 star = 7
2 star = 7
1 star = 14

I am aware this is easy maths and the figure I came up with just seemed quite high (3 figures)...so I wanted to double check.

Can anyone help with this easy maths?

I know this doesn't help the most recent post but since I created this thread in August, my business was 4.6 and now its just hit 4.8. :cool:

@Catherine Gabriel - Will wait for someone to help as I was also stuck but a variable that Trustpilot also include is the amount of recent 5* reviews as they are worth more than the older ones. Just thought I'd mention it.

Your average is 4.55

5 * 346 = 1730
4 * 15 = 60
3 * 1 = 3
2 * 2 = 4
1 * 39 = 39

Gives a total of 1836 stars from 403 reviewers so 4.55 average.

The tiny bit to make the 4.6 may be due to a lot of recent 5* reviews which are worth more @Catherine Gabriel

My business were able to source 10-14 5* reviews in a week which really pushed us up quicker.

The score isnt just based on the star rating of the reviews, there is some weighting applied to each review also.

Yes I know that. I mentioned it above to help Catherine.

so like older reviews lose weight to keep the score relevant with fresh reviews?

does anyone check these places anyway? I always google the company and check what people are saying on forums or reddit

Correct. The newer reviews are worth more as they are simply recent so a true reflection of the service at the moment. Whereas reviews from a years ago would be less relevant. Also take into account a company would (almost definitely!) want to improve on their standards so there could be additional employees/people leaving etc.

People do refer to Trustpilot a lot. We also use reviews.co.uk as our official partner.
