How is feedback calculated?

[tommy50607]

I have seen acounts with 100% feedback and negative ratings and also new acount with a few sales and 1 negative rating and like 96% feedback. How is it calculated? I have a seller acount with 36 ratings and 100% feedback, if I get one negative feedback, what will my rating be?

If you got a neg, your feedback score would be 8 positives and 1 neg (if feedback was NOT excluded according to what ebay tells you if you click on the "How is Feedback percentage calculated).

1/9=.11; times 100 = 11.11; 100-11.11=88.89, which would then be rounded.
