If you read the blog on Medium that I linked in this blog, you see when you get whale taxed, and how that happens.

So the Whale Tax (WT) kicks in once your deposit reaches more than 1% of the total supply of DRIP, which is capped at 1M tokens. So once your deposit in DRIP reaches 10k Drip, 5% WT is deducted from your available daily payout. 20k Drip — 10%, 30k — 15% and so on.

I think this helps you to do the math. I know I'm very far from being a whale, so I don't bother if you don't mind. 😉
