Well, I want to clarify that I'm totally new to this, so maybe I'm doing something wrong and I don't know it, I hope you can help me. My problem is that a few months ago I started using the revenue calculator and every time I wanted to know how profitable a product was giving me percentages that looked normal and understandable. but now using the same product to try to see what profitability gives me, it indicates that the profit margin for example is -626.60%.

this are the dimensions for my package: 50 x 40 x 60 ( cm ) , with a total of 20 ( kg ) and one unit is 0.1 kg.

the item price is 6 $. shipping price 0 $.

so here comes what makes no sense : PER UNIT THEY WOULD CHARGE ME 40.85 !!!!!

and in a listing almost the same as the one I want to make, the profit margin is 24.57% positive. how can that be? I don't understand.

I don't know what it is, if it's an error in my account, or if it's really like that and amazon fba is no longer useful.

It would be very foolish of me to send the products and get killed with the costs for not believing that this was really for real and not a system error or something, I have no idea I'm very lost.

if someone can please advise me and help me I would be very grateful!

greetings and thanks to those who can help me.
