Take the first $25 of your final value and multiply it by 5%. 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 between $25.01 and $1,000 and multiply it by 2.0%.
If your final value was more than $1,000, take the additional amount above $1000 and multiple it by 1.00%.
Add up these these amounts and that is your Final Value Fee.

For example, a $1500 item would cost:

$25 times 5% = $1.25
$975 times 2.0% = $19.50
$500 times 1.0% = $5.00
Total = $25.75

A $500 item would cost:

$25 times 5% = $1.25
$475 times 2.0% = $9.50
Total = $10.75
