Accurately assess liquidity mining risk using the impermanent loss calculator

When you decide to participate in DeFi liquidity mining, the impermanent loss calculator becomes the first tool to address. This tool helps investors accurately estimate risks and avoid falling into price fluctuation traps. Since the rise of the DeFi wave, decentralized financial products like Compound and Uniswap have emerged endlessly. Liquidity mining, with its dual incentive mechanisms of fee sharing and governance token rewards, has attracted many traders. However, few realize that behind this seemingly high-yield investment method lies a deadly risk—impermanent loss.

Why Does Liquidity Mining Cause Impermanent Loss?

Providing funds to a liquidity pool is not risk-free. When you supply liquidity to an ETH/USDC trading pair, you need to deposit both tokens in equal value. The key point is that the liquidity pool must always maintain a constant product—that is, the product of the quantities of the two tokens remains unchanged.

Imagine this scenario: you deposit 10 ETH and 1,000 USDC. If the price of ETH rises, the protocol will automatically sell some ETH for USDC to maintain balance, meaning your ETH holdings decrease, and you miss out on some of the upside. Conversely, if ETH’s price drops, the protocol sells USDC for ETH, increasing your ETH holdings, but since the price has fallen, your total assets may shrink.

This loss is called “impermanent” because as long as tokens remain in the liquidity pool, the loss fluctuates. The loss only becomes real when you withdraw your funds from the pool. Typically, we compare the “total assets from continuous mining” with the “total assets from simply holding tokens” to calculate the specific value.

Core Principles and Formulas of the Impermanent Loss Calculator

Understanding the mathematical principles behind impermanent loss is a prerequisite for using the calculator. In the constant product market maker (CPAMM) model, if initially we have a tokens A and B with quantities a and b, the constant product formula is: a × b = c (where c is a constant).

When the price of token A changes from Pa to a new price, the pool needs to rebalance. Based on the constant product formula, the new quantities can be derived as:

New quantity of token A = √(c / new price)

New quantity of token B = √(c × new price)

To intuitively understand this change, let’s illustrate with a concrete example.

Practical Calculation of Impermanent Loss in ETH-USDC Mining

Initial Conditions:

• ETH initial amount: 10
• USDC initial amount: 1,000
• ETH initial price: 100 USDC
• Constant product c = 10 × 1,000 = 10,000

Scenario 1: ETH price rises 10% to 110 USDC

Assets after mining:

• New ETH amount = √(10,000 ÷ 110) ≈ 9.535
• New USDC amount = √(10,000 × 110) ≈ 1,048.81
• Total asset value = 9.535 × 110 + 1,048.81 ≈ 2,097.66 USDC

If you didn’t mine, just holding the original assets:

• Total value = 10 × 110 + 1,000 = 2,100 USDC

Impermanent loss = (2,100 - 2,097.66) ÷ 2,100 ≈ 0.112%

Scenario 2: ETH price drops 10% to 90 USDC

Assets after mining:

• New ETH amount = √(10,000 ÷ 90) ≈ 10.541
• New USDC amount = √(10,000 × 90) ≈ 948.68
• Total asset value = 10.541 × 90 + 948.68 ≈ 1,897.37 USDC

Holding original assets:

• Total value = 10 × 90 + 1,000 = 1,900 USDC

Impermanent loss = (1,900 - 1,897.37) ÷ 1,900 ≈ 0.138%

From these cases, a general impermanent loss formula can be derived for pools with 1:1 staking ratios and one stablecoin:

Impermanent Loss = [(r+2) - 2√(r+1)] ÷ (r+2)

where r is the multiple of price change. If the token ratio in the pool is not 1:1, multiply the formula result by the proportion of the volatile token to get a more precise estimate.

Comparative Analysis of Impermanent Loss in Different Scenarios

Key Finding 1: Larger price swings lead to greater impermanent loss

As shown, whether prices go up or down, any change causes impermanent loss. The extent of loss is non-linear with respect to price volatility—more volatility results in higher loss ratios.

Key Finding 2: Downward price movements cause more impermanent loss than upward movements

For the same magnitude of fluctuation, price drops lead to larger impermanent losses than equivalent increases. This is because the loss calculation is percentage-based, and the base is smaller during declines. Using a professional impermanent loss calculator reveals this asymmetry clearly.

Key Finding 3: Unequal token ratios can actually reduce impermanent loss

Counterintuitive as it sounds: the higher the proportion of stablecoins in the pool, the smaller the impermanent loss. The more unbalanced the staking ratio of the two tokens, the lower the absolute impermanent loss. This is because when one token dominates, price fluctuations have a diluted impact on overall assets.

Risk Assessment Recommendations When Choosing a Mining Pool

Step 1: Use the impermanent loss calculator for simulation

Before investing, input your chosen token pair and expected price fluctuation range into the calculator. This helps you see the worst-case loss, aiding rational decision-making.

Step 2: Prefer stablecoin pairs

Pools like ETH/USDC or BTC/USDT, where one side is relatively stable, can effectively hedge volatility, making impermanent loss more manageable.

Step 3: Be cautious with high-volatility altcoin pools

Some small tokens offer tempting mining rewards, but extreme price swings can wipe out all gains or even cause capital loss. Simulating worst-case scenarios with the calculator is essential.

Step 4: Pay attention to token staking ratios

Even within the same trading pair, different pool ratios (e.g., 1:1 vs. 2:1) result in different impermanent loss levels. Comparing these with the calculator helps select the most suitable configuration.

The Development of the DeFi Market and Investor Choices

Since the DeFi boom, decentralized finance has gone through multiple cycles. Liquidity mining has indeed generated substantial returns over recent years, but the market has also faced numerous smart contract security incidents. Using an impermanent loss calculator to scientifically assess risks has shifted from optional to essential.

Any investor participating in liquidity mining must recognize that impermanent loss is not a minor cost to ignore; it can be a decisive factor in overall returns. By properly utilizing the calculator and understanding risks under different market conditions, you can make smarter decisions in the DeFi space. Although DeFi still faces many technical and risk challenges ahead, a thorough understanding of the core concept of impermanent loss is an essential lesson for every liquidity provider.
