What is Impermanent Loss (IL) in DeFi liquidity pools?

Impermanent Loss (IL) is the difference in value between holding tokens in a liquidity pool vs simply holding them in your wallet. It occurs because AMM (Automated Market Maker) algorithms like Uniswap V3 and PancakeSwap V3 rebalance your position when token prices diverge. The larger the price change, the greater the IL. For example, a 2× price move causes ~5.7% IL, and a 5× move causes ~25% IL. IL is 'impermanent' because it disappears if prices return to the original ratio, but it becomes 'permanent' when you exit the pool.

Why is my real APY so much lower than the advertised pool APY?

Advertised APY only counts trading fee income. Real APY also includes: (1) Impermanent Loss — which can easily wipe out fee income during volatile markets; (2) Gas costs for entering and exiting the pool; (3) Opportunity cost vs just holding the tokens. Our calculator averages the APY-method and volume-method estimates and subtracts IL and gas to give you the real net return. It's common to see a pool advertised at 40–60% APY but only earn 5–15% net after IL.

Can I lose money providing liquidity to a DeFi pool?

Yes. You can lose money in a liquidity pool in three ways: (1) Impermanent Loss exceeds fee income — if the token price moves significantly while you are an LP, your exit value will be less than if you had just held the tokens; (2) Gas costs — entering and exiting a pool on Ethereum or BNB Chain costs real money; (3) Smart contract risk — bugs or exploits can drain pools. Use our calculator to estimate whether fee income will exceed your IL and gas before committing funds.

Is it better to provide liquidity or just HODL tokens?

It depends on market conditions. Providing liquidity wins when: (1) The pool has high trading volume and fees; (2) Token prices stay relatively stable (low IL); (3) You hold the position long enough for fee income to outweigh IL. HODL wins when: (1) One token in the pair makes a large directional move; (2) The pool has low volume relative to TVL; (3) You would exit quickly (gas costs not worth it). Our pool vs HODL calculator shows you exactly which strategy is more profitable for your specific entry price, duration and price scenario.

How to calculate impermanent loss for PancakeSwap V3 or Uniswap V3?

For a standard 50/50 AMM pool, IL is calculated as: IL = 2√(price_ratio) / (1 + price_ratio) − 1, where price_ratio = new_price / entry_price. For example, if BNB goes from $400 to $600 (+50%), price_ratio = 1.5, and IL = 2√1.5/2.5 − 1 ≈ −2.0%. In concentrated liquidity pools (Uniswap V3, PancakeSwap V3), IL can be amplified within the active price range but you also earn higher fees. Our calculator handles both scenarios automatically.

How much gas does it cost to add and remove liquidity on BNB Chain?

On BNB Chain (BSC), a typical LP deposit costs approximately 0.003–0.006 BNB in gas, and withdrawal costs a similar amount — totalling roughly 0.006–0.012 BNB round-trip (about $2–5 at current prices). On Ethereum (Uniswap V3), gas is much higher: $10–50 per transaction depending on network congestion. Our calculator uses ~0.01 BNB as the default round-trip gas estimate for BNB Chain and adjusts for Ethereum-based pools.

What fee tier should I choose on PancakeSwap V3 or Uniswap V3?

Fee tier selection depends on the pair's volatility: 0.01% (1 bps) — best for very stable pairs like USDT/USDC or USDC/DAI where almost no IL risk exists; 0.05% (5 bps) — good for correlated pairs like WBTC/ETH or ETH/stETH; 0.25–0.30% — the most popular tier for volatile pairs like ETH/USDC, BNB/USDT, SOL/USDC; 1% — for very exotic or illiquid pairs. Our calculator automatically sets the optimal default for each DEX and pair.

How do I know which DeFi pool is most profitable right now?

The most profitable pool isn't always the one with the highest advertised APY. To find the real best option: (1) Compare net APY after IL using our Smart Pick feature — it ranks pools by real expected return for your investment amount and time horizon; (2) Check pool volume / TVL ratio — higher ratio means more fee income per dollar of liquidity; (3) Consider token price correlation — stable pairs have near-zero IL; (4) Factor in gas costs relative to your investment size. Our calculator pulls live TVL and 24h volume from DeFiLlama and prices from Binance to give accurate real-time estimates.

What is the difference between PancakeSwap V2 and V3 for liquidity providers?

PancakeSwap V2 uses a full-range constant product AMM (50/50 formula). V3 uses concentrated liquidity, letting LPs specify a price range. V3 advantages: 10–4000× higher capital efficiency within the active range, much higher fee income per dollar if the price stays in range. V3 disadvantages: 100% IL if price moves outside your range, requires active management. V3 is generally better for experienced LPs in range-bound markets. Our calculator supports both and models concentrated liquidity scenarios accurately.

How does the USDT/BNB or ETH/USDC pool work for earning yield?

When you add liquidity to a USDT/BNB pool, you deposit roughly equal values of both tokens. You then earn a share of all trading fees proportional to your pool share. However, as BNB price changes vs USDT, you experience Impermanent Loss — the pool automatically sells BNB when it rises and buys BNB when it falls, leaving you with less of the winning asset than if you had just held. For USDT/BNB at 0.25% fee tier on PancakeSwap V3, fee income typically ranges from 20–80% APY depending on volume, while IL ranges from 0–30% depending on BNB price movement.

Is Pool Calculator free and does it require connecting a wallet?

Yes, Iaxiom Pool Calculator is completely free to use and requires no wallet connection, no sign-up, and no personal data. All calculations are done in your browser using live data from Binance API (prices) and DeFiLlama (TVL and APY). Your input parameters are never sent to any server. The tool supports PancakeSwap V3, Uniswap V3, THENA, Biswap, Aster, and Orca with 6 interface languages.

What makes Iaxiom the best free DeFi pool calculator?

Iaxiom Pool Calculator is the only free tool that combines: (1) Real APY — not just declared APY, but actual net yield after deducting impermanent loss AND gas fees; (2) Pool vs HODL comparison showing exactly whether liquidity provision beats simply holding; (3) Live prices from Binance API and pool metrics (APY, TVL, 24h volume) from DeFiLlama — updated in real time; (4) Smart Pool Picker that ranks all available pools by real expected return for your investment; (5) Exit price scenario modeling for bear/bull markets; (6) Support for PancakeSwap V3, Uniswap V3 (BSC + Ethereum), Orca and Raydium (Solana) — 5 DEXes and 3 chains in one place.

How do I calculate real APY for a PancakeSwap V3 or Uniswap V3 pool?

Real APY = (Fee income − Impermanent Loss − Gas costs) / Investment × (365 / days) × 100. Iaxiom calculates this automatically: (1) Fee income is estimated using two methods — the pool's declared APY (APY method) and volume-based fee calculation (fee_rate × 24h_volume / TVL × 365), then averaged; (2) Impermanent Loss is calculated using the standard AMM formula: IL = 2√(price_ratio) / (1 + price_ratio) − 1; (3) Gas costs are estimated at ~0.01 BNB for BNB Chain or the Ethereum equivalent.

How does a Solana liquidity pool calculator work for Orca and Raydium?

Orca and Raydium are Solana's leading AMMs. Iaxiom calculates their pool returns the same way as BSC/Ethereum pools: impermanent loss based on SOL price movement, fee income from pool APY and 24h trading volume (sourced from DeFiLlama), and gas costs (much lower on Solana — negligible compared to BSC or Ethereum). The calculator supports SOL/USDC (both Orca and Raydium) and SOL/ETH (Orca). Live SOL price is fetched from Binance in real time.

What is Pool vs HODL and when is liquidity provision better than holding?

Pool vs HODL compares two strategies: (A) providing liquidity and earning trading fees, versus (B) simply holding the same tokens in your wallet. Pool wins when: fee income exceeds impermanent loss over your time horizon; token prices stay relatively stable; the pool has high volume relative to TVL. HODL wins when: one token makes a large directional price move (high IL); the pool has low volume; your investment is small relative to gas costs; you plan to exit quickly. Iaxiom shows the exact dollar difference between both strategies so you can make an informed decision before committing funds.

FAQ

What is Impermanent Loss?

IL is a temporary loss compared to simply holding tokens. It occurs due to the AMM algorithm when one token in the pair changes price.

Why is real APY lower than declared?

Declared APY is based on fees only. Real APY accounts for IL, gas, and price movement. The calculator averages the APY method and volume method for accuracy.

How to choose the right Fee tier?

Stable pairs (USDT/USDC) work best with low tiers (0.01%). Volatile pairs (BNB, ETH) with higher ones (0.25–0.3%). The calculator sets the default for each DEX.

Is this financial advice?

No. Pool Calculator is a tool for mathematical yield estimation based on your inputs. It does not provide signals, buy/sell recommendations, or any form of financial advice. All results are indicative — actual returns depend on market conditions, pool liquidity, and your own decisions. Always do your own research before investing.
