Hi, Repeat buyers is a great feature introduced by Fiverr for showcasing the people that these sellers have same buyers who have exceptional customer retention rate.. I have following stats. Can anyone tell how the percentage is calculated ?

It's the percentage of buyers who ordered from you again out of all your buyers in the last 90 days. I'm not good enough at math's to explain it further in understandable language, but I think that explains it all!
