FM20 Coach Calculator for Football Manager

I've updated my popular five star coach calculator for Football Manager 2020. This calculator can be used to work out the star rating of each coach in each of the coaching assignments.

Football Manager Tools | FM20 Coach Calculator

Welcome to my all new and improved FM20 coach calculator.

We all want the best coaches available for our clubs to help us with player development, in the youth and the first teams. It sometimes seems a bit hit and miss with signing coaches, so I created a tool that enables me to calculate the staff star rating ahead of signing them so we can make sure we only have 5-star coaches at the club (or as close to as we can).

Simply enter the coaches mental attributes into the FM20 coach calculator, and then, depending on whether you’re looking for a fitness coach, general coach or goalkeeping coach, enter the attribute values that are specific to the coach in question, e.g., for a fitness coach you only need to enter their Determination, Level of Discipline and Motivating mental attributes and then their Fitness attribute. The FM20 coach calculator will then give you their star rating.


Coaches only play a small role in developing players at your club. You should also ensure you upgrade your training facilities to make sure your players have the best equipment available to help them reach their potential.

Until next time.

  1. Would you be able to share the formulas you used? I want to make a excel sheet for my personal use and I can’t find these formulas anywhere. Thanks!

    1. There are lots of posts on the internet with the formulas. Mine are hidden behind code which if I copied and pasted here wouldn’t make sense. For example, IF(fieldname8*6+fieldname13*3+(fieldname3+fieldname4+fieldname5)*2>=270,5,IF(fieldname8*6+fieldname13*3+(fieldname3+fieldname4+fieldname5)*2>=240,4.5 etc.

      1. The first line break of code breaks down to Attx6 + Techx3 + (DDM)x2 If it is equal to or greater than 270, theyre a 5 star coach. Between 270 and 245 theyre 4.5 star. Is that right?

  2. Ok I just found them. I’ve literally spent hours on this. I just remembered FM19 is when they updated the training stuff. I couldn’t find anything for FM20 but when I searched FM19 I finally found them. Thanks for the help!
