Why WordPress Is Not Giving 50% Of Each Sale?

I recently launched my first WordPress theme. I am selling in $19. But each sale is giving me $4.90. I am selling html/psds. I always get more then 50% of each sale. But in WordPress its different. If any one can help or suggest, If I am missing something?

Hi

( ( Item Price - Buyer fee ) - TAX ) - Author fee = Your Earning
Check your Author fee here:

for wordpress buyer you can check by go to edit your item then in description and price section.

US Tax Treaties:

Thanks

Wordpress category has a fixed buyer fee of $12.00
(HTML = $4.00, PSD = $2.00)

List Price: $19.00
Buyer Fee: $12.00
Gross income: $19.00 - $12.00 = $7.00
US Royalty Withholding Tax: $7.00 * 0.00% = $0.00
Author Fee: $7.00 * 30.00% = $2.10
Earnings: $7.00 - $0.00 - $2.10 = $4.90
