Calculating LP Rewards — Simplified

I’ve learned a unique quirk about liquidity pools and wanted to share what I’ve figured out.

How are LP rewards actually calculated, and what drives profit?

I used Blockscout to estimate the size of the liquidity pool on Mordor and determine what percentage of it I own. It turns out I’m sitting on about 57% of the pool — but I wasn’t seeing meaningful rewards.

So I dug into the formulas (from the blog) and ran them through AI to better understand what’s going on. Here’s the simplified version:

LP Profit ≈ DEX Fees − Impermanent Loss

Now here’s the counterintuitive part:

Impermanent loss increases when price moves — even if the token goes up.

At first, that doesn’t make sense. You’d think if the token price increases, LP holders should benefit. But that’s not how AMMs work.

As a liquidity provider, you’re constantly being rebalanced by the AMM:

  • When price goes up → the pool sells your appreciating token

  • When price goes down → the pool buys more of it

This keeps the pool balanced, but it means:
:backhand_index_pointing_right: You’re effectively selling winners and buying losers automatically

That rebalancing is what creates impermanent loss.

Yes, you earn a portion of DEX fees from every swap — but:

If fees < impermanent loss, you’re not actually making money.


Key takeaway:

:backhand_index_pointing_right: Liquidity pools hate volatility
:backhand_index_pointing_right: Liquidity providers need consistent volume, not wild price swings


So what actually makes money in a liquidity pool?

Volume.

High, steady trading activity (with relatively stable prices) is where LPs finally start to profit.


Reality check (Mordor):

From what I can see on Blockscout:

  • Only ~1–2 swaps per day

  • Very low trading volume

At this level of activity:
:backhand_index_pointing_right: There simply aren’t enough fees being generated
:backhand_index_pointing_right: LP providers are unlikely to see meaningful rewards


If anyone sees this differently or has additional data, I’d love to compare notes — still learning this space.

volume is key for ghost chain rewards and LPs…
