Providing liquidity to a decentralized exchange can earn trading fees, but it changes the assets you hold. In a pool that automatically rebalances as traders swap, the quantity of each token in your position shifts when their relative prices move. Comparing the value of that rebalanced position with simply holding the original tokens reveals a risk measure commonly called impermanent loss.
The name can be misleading: the difference is not imaginary, and it does not have to disappear. It describes a comparison at a chosen moment. If you withdraw after the prices have diverged, the relative shortfall versus holding becomes realized in your portfolio, before considering fees, incentives, gas, taxes and other factors. CryptoWave’s DEX liquidity-risk calculator is a simplified scenario tool to help make those assumptions visible.
What an LP position is being compared with
Impermanent loss compares two paths that start with the same pair of assets and the same initial value. In one path, the assets remain in a liquidity pool and the automated market maker adjusts their quantities as trades respond to changing prices. In the other path, the provider keeps the original token quantities outside the pool. The percentage difference between the two values is the relative effect of rebalancing.
This is not necessarily the same as a dollar loss from the starting deposit. Both paths can gain value if the market rises or lose value if it falls. The key question is whether the pool position performed differently from holding the same starting assets. That distinction matters when an LP compares a pool with a simple portfolio, rather than comparing the current balance only with the initial deposit.
A simple constant-product example
Many familiar AMMs use a constant-product relationship for a pair of token reserves. In the idealized version, the reserve quantities multiply to a constant, often written x times y equals k, before fees and other protocol details. When the outside market price changes, arbitrage trades can move the pool toward the new relative price. The pool then holds a different mix of the two tokens than it did at the start.
For a balanced, equal-value deposit in a basic constant-product pool, a common simplified comparison is based on the ratio between the final and initial relative prices. If one token becomes four times more valuable relative to the other, the model gives a pool-versus-hold difference of about negative 20%, before fees. This does not mean the LP’s total dollar balance necessarily fell by 20%; it means the modeled pool value is lower than the value of holding the original amounts under those assumptions. The Uniswap v2 whitepaper describes the mechanics of a constant-product pair and the way arbitrage interacts with pool prices.
Relative price matters more than a single token’s direction
Impermanent loss is driven by how the assets move against each other, not simply whether both rise or both fall against dollars. If two assets maintain a close relationship, their relative price may change less than either token’s dollar price. A pair of assets designed to track similar values may therefore have a different rebalancing profile from a volatile token paired with a major asset, although stable-value assets can depeg and carry their own risks.
Correlation is not a guarantee. Tokens that move together during calm conditions can diverge during market stress, a protocol incident or a liquidity shock. A provider should inspect the pair’s historical behavior and understand what each token represents, but historical correlation cannot ensure that the same relationship will continue. Consider scenarios where one asset rises sharply, falls sharply or loses its intended peg.
Fees and incentives belong in a separate line
Trading fees can offset some or all of the modeled pool-versus-hold difference over a period, but the offset is not automatic. Fee income depends on actual trading activity, pool rules, liquidity share, fee tier and how a position is managed. Incentive rewards can add another source of return, but they may be variable, time-limited or paid in a volatile token. Subtract network transaction costs, deposit and withdrawal costs, management costs and relevant taxes when evaluating an actual position.
Do not compare a gross annual percentage advertised by a dashboard directly with a model of impermanent loss over a different time period. First learn how the rate was calculated, whether rewards are included, and whether the displayed figure is historical or projected. Trading volume and liquidity can change quickly. A high recent fee rate may reflect a short-lived event rather than a stable future stream.
Concentrated liquidity changes the shape of exposure
Some AMMs let providers choose a price range rather than supplying liquidity across a broad range. Concentrated positions can use capital more efficiently while the market stays within the selected range, but they can also become inactive for trading once the price moves outside it. The token mix can become heavily weighted to one side at the boundary, and the provider may need to reposition if they want to resume earning fees.
A simple equal-weight constant-product calculator does not model concentrated positions, changes in fee income, active rebalancing or range-management decisions. It is useful for learning the basic comparison, not for evaluating every protocol design. Read the documentation for the exact pool version and position type before using a calculator result as a proxy for your own exposure.
Liquidity depth, price impact and slippage are different concepts
Pool liquidity describes the assets available for swaps; price impact is the movement caused by a specific trade against that liquidity. A larger trade relative to a pool’s reserves generally has a larger effect on the marginal price in a basic AMM. The impact depends on the trade direction, fee and pool design. Total value locked is only a broad snapshot and does not by itself tell you the exact price for a trade.
Slippage is the difference between an expected quote and the eventual execution. It can include price movement while a transaction is pending, competing transactions and route changes. Price impact is attributable to the trade interacting with the pool; slippage tolerance is a transaction setting that controls how much the execution may differ before it reverts. A high tolerance does not improve liquidity—it can allow a worse execution to proceed. Always examine the quote and minimum received amount before signing.
How to use a scenario calculator responsibly
Enter the initial position value and the price change for both assets relative to a consistent starting point. The CryptoWave tool applies a simplified 50/50 constant-product model to compare the pool with holding, then allows fees and costs to be entered separately. Its second scenario is only an approximation of price impact for a balanced pool; it is not a live swap quote and does not query reserves or route through an aggregator.
Change one assumption at a time and test several paths. A useful review includes small divergence, large divergence, a token moving in each direction, zero fee income and a realistic cost estimate. Treat the output as a way to understand sensitivity. Do not infer that a positive historical fee total will continue or that a model captures smart-contract, bridge, oracle, governance, depeg or exploit risk.
Research the pool and transaction path
Before supplying assets, verify the protocol’s official domain, chain, pool contract and token addresses. Read the pool’s fee rules and documentation. Check whether liquidity is fragmented across fee tiers or versions, whether the displayed pool is active and whether the tokens have meaningful external liquidity. A familiar token name is not proof of a genuine contract, and a large headline TVL does not certify a protocol.
Consider contract history, audits and security disclosures without treating any one of them as a guarantee. Understand upgrade permissions, admin controls and the process for pausing or changing contracts. If the strategy depends on a bridge or a third-party vault, include those layers in the risk review. Keep experimental activity separate from long-term holdings and do not grant an unfamiliar site more token permissions than the intended action requires.
A measured LP checklist
- Write down the starting token quantities and relative price.
- Model divergence in both directions and account for the pool version.
- Estimate fee income separately from impermanent loss and incentives.
- Include entry, exit, gas, management and tax costs where relevant.
- Check current reserves, trade size, route, price impact and minimum received.
- Verify network, contracts, approvals and provider documentation.
- Reassess when the price leaves a concentrated range or pool conditions change.
