The Modify Fee Rates option allows you to edit the fee rates the calculator is using at
any time. When you click on the Modify Fee Rates link it will bring up a dialog window where you can
edit all of the different eBay Fee Groups. You can see a screenshot of Modify Fees dialog below...

The first step in editing your fee rates would be to decide which category of eBay Fee Rates you are
editing. Are you editing the fee rates for eBay.com, eBay Motors, eBay Stores, etc.? The calculator allows you to edit
the fee rates for all of them. To choose between one or the other simply click on the appropriate radio button at the
top of the dialog that corresponds to the category you would like to edit. In this case, I'll choose
eBay because I'll be editing the fee rates for eBay.com. After you've chosen your category you need
to choose your Fee Group. Since eBay fees come in many different forms (Insertion Fees, Final Value
Fees, Listing Upgrade Fees, etc.) I like to divide them up into different categories, or what I call
Fee Groups. Once you choose the Fee Group you would like to edit the approriate fee
table for that group will be displayed on the right side of the dialog. In this case, I'll choose the Listing
Upgrade fee group because I would like to edit the Listing Upgrade fees for eBay.com. Once I click on the
Listing Upgrade Fees option the Listing Upgrade Fees Table appears which allows me
to enter in any amount I want for any upgrade I want. Once I'm finished making my changes, I simply click on the
"OK" button to save my changes. If you're editing your fee rates and you've found that you've made a mistake simply
click on the "Reset to Default" button to reset all of the fee rates the calculator is using back to their initial
(default) values.
