Final Value Fees
At the end of an auction, you will be charged 
a Final Value Fee based on the final sale price 
(final value) of your item:


Regular and Reserve Auctions (when the 
reserve has been met)

The final value is the closing bid. Remember, 
there is no Final 
Value Fee charged if the reserve is not met.

Dutch Auctions

The final value is the lowest successful bid, 
multiplied by the quantity of items you sold.




Then here's how you calculate your Final Value 
Fee 


 
Take the first $25 of your final value, and 
calculate 5% of that. If your   item sold for $25 
or less, this is your Final Value Fee.
 
If your final value was more than $25, take 
the additional amount, from $25.01 to $1,000, and 
calculate 2.5% of that.
 
If your final value was more than $1,000, 
take that additional amount and calculate 1.25% 
of the remaining amount.
 
Add these amounts together and you have your 
Final Value Fee!
