Impermanent loss occurs when the price ratio of tokens in a liquidity pool changes. Here's the math, when it becomes permanent, and how to minimize it.
This guide is designed for first-pass understanding. Start with core terms, then apply the framework in your own account workflow.
Impermanent loss is the hidden cost of providing liquidity in DeFi. It's the reason your LP position might be worth less than if you'd simply held your tokens in your wallet; even though you earned trading fees the entire time. Understanding impermanent loss is essential for anyone considering yield farming, and the math is simpler than most people think.
Impermanent loss is the difference in value between holding tokens in a liquidity pool versus simply holding them in your wallet. It occurs when the price ratio of pooled tokens changes; the greater the divergence, the larger the loss. It's called "impermanent" because the loss reverses if prices return to their original ratio, but it becomes permanent when you withdraw your liquidity.
When you provide liquidity to an automated market maker (AMM) like Uniswap, you deposit two tokens in equal value; say $5,000 of ETH and $5,000 of USDC. The pool uses these tokens to facilitate trades.
Here's the key insight: the AMM constantly rebalances your position to maintain equal value of both tokens. If ETH's price doubles, the pool doesn't just let you hold your original ETH and enjoy the gains. Instead, it sells some of your ETH for USDC to maintain the 50/50 balance. You end up with less ETH and more USDC than you started with.
The result: your LP position is worth less than it would have been if you'd just held both tokens separately in your wallet. That difference is impermanent loss.
Let's walk through a concrete example with real numbers.
Starting position:
Now ETH doubles to $4,000:
Arbitrageurs trade with the pool until the pool price matches the market price. For the pool price to reflect $4,000/ETH while maintaining k = 2,000, the new balances become:
If you had just held:
The impermanent loss: $6,000 - $5,656 = $344, or about 5.7% of the held value.
Notice what happened: the pool sold some of your ETH as the price rose. You ended up with 0.707 ETH instead of 1 ETH, plus extra USDC. You still made money overall ($5,656 vs $4,000 deposited), but you made less than you would have by just holding. That gap is the impermanent loss.
Impermanent loss is the difference between holding two tokens in your wallet vs providing them as liquidity in a DEX pool. When the price ratio of the tokens changes, the pool automatically rebalances — you end up with more of the cheaper token and less of the expensive one. The greater the price divergence, the larger the loss.
Impermanent loss becomes 'permanent' when you withdraw your liquidity at different prices than when you deposited. If the prices return to their original ratio, the loss disappears. However, trading fees earned while providing liquidity can offset the loss — that's the trade-off you're making.
Provide liquidity to pools with correlated assets (ETH/stETH, USDC/USDT) where the price ratio stays stable. Use concentrated liquidity positions in narrower ranges. And choose pools with high trading volume — the fees earned are more likely to outweigh impermanent loss.

What Is Yield Farming? DeFi Returns, Risks, and Strategies
Yield farming means providing liquidity to DeFi protocols in exchange for token rewards. Here's how it works, realistic return expectations.
Impermanent loss depends on how much the price ratio between the two tokens changes; not the direction. Whether ETH goes up or down relative to USDC, you experience IL. Here's how the math scales:
| Price Change | Impermanent Loss | Example |
|---|---|---|
| 1.25x (25% move) | ~0.6% | ETH: $2,000 to $2,500 |
| 1.5x (50% move) | ~2.0% | ETH: $2,000 to $3,000 |
| 2x (100% move) | ~5.7% | ETH: $2,000 to $4,000 |
| 3x (200% move) | ~13.4% | ETH: $2,000 to $6,000 |
| 4x (300% move) | ~20.0% | ETH: $2,000 to $8,000 |
| 5x (400% move) | ~25.5% | ETH: $2,000 to $10,000 |
The relationship isn't linear; it accelerates. A 2x move costs you about 5.7%, but a 5x move costs you over 25%. For highly volatile tokens that can 10x or crash 90%, impermanent loss can be devastating.
Impermanent loss also works symmetrically. If ETH drops by 50% instead of rising, the IL is the same magnitude. The pool buys more ETH as the price drops (maintaining the balance), so you end up with more ETH and less USDC than if you'd held. When the asset drops, this means you're holding more of the depreciating token.
The "impermanent" in impermanent loss refers to the fact that if prices return to their original ratio, the loss disappears entirely. The pool rebalances back to your original token amounts, and you haven't lost anything (and you've earned trading fees in the meantime).
The loss becomes permanent when you withdraw your liquidity while prices have diverged from your entry point. At that moment, the rebalancing the pool did; selling your appreciating token or buying more of the depreciating one; is locked in. You've realized the loss.
This creates a psychological trap. If you're in an LP position with significant impermanent loss, you might think "I'll just wait for prices to return." But what if they never do? What if the divergence increases? At some point, holding an LP position with growing impermanent loss is functionally equivalent to a losing trade — you're just choosing not to realize it.
The decision to withdraw should be based on whether you believe the trading fees you'll earn going forward will outweigh the expected impermanent loss; not on hoping prices return to your entry.
You don't need to do the math yourself. Several tools help you estimate or track impermanent loss:
The most important number isn't the impermanent loss alone; it's net return: fees earned minus impermanent loss. A position with 8% impermanent loss but 12% in fees earned is still profitable. A position with 3% IL but 1% in fees is not.
You can't eliminate impermanent loss if you're providing liquidity to a standard AMM pool, but you can reduce it:
The name is somewhat misleading and has been criticized. The loss is called "impermanent" because it reverses if token prices return to their original ratio. But in practice:
Some people prefer the term "divergence loss"; it more accurately describes the phenomenon as a loss caused by price divergence between the two tokens. Whatever you call it, the economic impact is the same.
The fundamental question every liquidity provider should ask: am I better off providing liquidity, or should I just hold these tokens in my wallet?
The answer depends on three factors:
A rough rule of thumb: on major pairs with high volume (ETH/USDC on Uniswap), fee income typically outweighs impermanent loss over longer time periods; assuming you don't withdraw during extreme price moves. On low-volume exotic pairs, IL often dominates, and you'd be better off holding.
There's no universal answer. Each pool, each time period, and each market condition produces different results. The only way to know your actual performance is to track it.
Let's look at a few scenarios to make impermanent loss concrete:
Scenario 1: Moderate move, high-volume pool
Scenario 2: Large move, low-volume pool
Scenario 3: Stablecoin pool
These examples illustrate why pool selection is everything. The same strategy that prints money on a high-volume stablecoin pool can lose you thousands on a volatile small-cap pair.
Uniswap V3 introduced concentrated liquidity, which deserves special mention in any impermanent loss discussion. Instead of providing liquidity across all possible prices (0 to infinity), you choose a specific range; say, $1,800 to $2,200 for ETH.
Within your range, you earn far more fees because your capital is deployed more efficiently. But if the price moves outside your range, two things happen:
Concentrated liquidity amplifies both fee income and impermanent loss. A 2x price move in a concentrated position can result in far more than the 5.7% IL you'd see in a standard pool. The tighter your range, the higher the amplification in both directions.
If you're providing liquidity across multiple DeFi protocols, tracking your actual performance, not just the APY displayed by the protocol, is critical. Your real return is fees earned minus impermanent loss minus gas costs.
Clarity helps you track your DeFi positions alongside your broader portfolio, so you can see how your LP positions are actually performing compared to simply holding. Connect your wallets and exchange accounts to get a unified view of your crypto allocations, including LP tokens, staked positions, and lending deposits. Making informed decisions about whether to stay in, adjust, or withdraw requires clear data — and impermanent loss makes that data harder to intuit without the right tools.
Before providing liquidity, do the math. Use an impermanent loss calculator to understand what different price scenarios mean for your position. Look at historical volume and fee data for your target pool. Ask yourself: would I be happy holding a mix of these two tokens if prices move significantly? If the answer is no, providing liquidity to that pair probably isn't right for you.
