Point Calculator Earnings with tax or without tax?

[encan]

When calculating my points should i enter the gross paid amount or the net amount that was deposited into my bank account?

For example,

I get 2000,00 new turkish liras GROSS.
After taxes it becomes about 1500,00 NET.

for a period of 12 months should i calculate 2000x12 or 1500x12?

Thank you in advance for your responses.
