Hi,
I am trying to work out the following:

I have a database of Clients and I have how long they have been a client of the business. I want to work out percentages based on:

% of clients who have been with the business less than one year, between 1 to 5 years, between 5 to 10 years and finally over 10 years.

There are 3345 active clients. So I would want to know the total % for each of the above criteria - if that makes sense?

Any ideas?

Many thanks

Lesley

will you consider to split the 'how long' column into 2 with years & months?

this solution based on the 'how long' column with a different format that can be hidden
