Cardano Stakepool cost/fees Demystified

Cardano Stakepool cost/fees Demystified

You’ve finally decided to delegate your ADA (what took you so long, anyway?) You fire up Daedalus in the search for the perfect pool and you notice that all pools have some sort of costs associated with them: “Pool margin” and “Cost per epoch”. What’s up with that?

Do you need to pay 340 ADA each 5 days in order to delegate to a pool? No, of course not. You don’t have to pay anything (except some one-time minimal transaction fees).

I know, the terms can be confusing. Don’t worry, you’re not the only one who got confused by the whole cost issue. Here’s a recent snapshot from Reddit:

Let me walk you through a typical scenario so you can have a better understanding of the whole process.

Step 1. You find a pool to delegate your ADA. Click, click, next, next, enter spending password, next, continue and poof, you pay ~2.17 ADA and you’re delgated. Why 2.17 ADA? I won’t bore you with the details but some transactions are required behind the scenes for you to be able to delegate. The good news is that if you decide to delegate to another pool, you’ll only pay a ~0.17 ADA transaction fee. That’s it. No more taxes. You’re all set.

Step 2. Epochs go by and your pool starts minting blocks. This is good! You’ll get rewards. For the sake of simplicity we’re going to ignore the treasury tax. Let’s assume that 1 block = 1000 ADA. Cost per epoch = 340 Pool margin = 5% Pool mints 10 blocks

Step 3. Time to do the math. 10 blocks * 1000 ADA = 10000 ADA. Out of the 10000 ADA taxes are subtracted. First, the scarry “Cost per epoch”. So that’s 10000–340 = 9660 ADA (Why 340? Because that’s the minimum allowed by the protocol and most stake pool operators go for that value. ) “Pool margin” comes next, so that’s 9660 ADA — 5% = 9180 ADA The remaning 9180 ADA will be distributed to the delegators, proportionate to their stake.

Pretty simple, eh?
