How to calculate what percentage of customers account for 80% of the expenditure.

[TATUPOCCARD]

Hello! I have a table with the following data:

1. Customer code
2. Brand
3. Gauge
4. Total volume sold
5. Total spending

I want to know how to calculate what percentage of customers (those with a volume greater than 0) account for 80% of the total spending. In other words, an 80/20 Pareto analysis.

Thank you!

Thank u for the response! I may have expressed myself poorly, but I don't want to fix that 20%. I need to know what % of customers account for 80% of the spending. In other words, perhaps for one brand, 100 out of the 200 customers do this (50%), but for another, only 50 out of the 5000 do (10%). What I want to find out is those 100 or 50 customers in each example.
