What is the Impermanent Loss Calculator?
Compare a simplified 50/50 constant-product pool position with holding the same starting assets. The calculator forms the final-to-initial price ratio and applies the standard 2√r ÷ (1+r) relative-value factor.
This calculator turns a crypto or blockchain scenario into arithmetic that can be inspected and repeated. It names the inputs, preserves intermediate values, states the equation, and displays the assumptions that determine the answer. It does not quietly download an asset price, exchange fee, network condition, reward rate, difficulty value or token supply.
That distinction matters because crypto markets and protocols change quickly. A number that was reasonable yesterday may not represent the next transaction, block, reward period or unlock. The result is therefore a model of the values entered, not a forecast, endorsement or promise. Read the result label and limitations before using the number in a trading, mining, staking, treasury or portfolio decision.
Similar-looking crypto measures answer different questions. Profit includes price movement, a trading-fee estimate isolates explicit percentage charges, market capitalization multiplies price by circulating supply, and fully diluted valuation uses a broader supply assumption. Keeping those concepts separate prevents a polished result from being interpreted as something the equation never measured.
How to use the Impermanent Loss Calculator
Collect or confirm Currency, Initial relative token price, Final relative token price, Starting liquidity value from the exchange, wallet record, protocol documentation, mining meter, token schedule or planning scenario that defines the analysis. Use the same asset, quote currency, time boundary and fee convention across related inputs.
- Select the display currency where offered. Currency selection formats amounts; it does not convert exchange rates.
- Enter every required value. The page rejects blanks, non-finite numbers, impossible percentage relationships and values outside the documented ranges.
- Select Calculate Impermanent Loss. Review the large answer, four colored supporting details, scale, caution and every calculation step.
- Recheck decimal placement carefully. A rate entered as 2 means 2%, while an asset quantity may validly contain many decimal places.
- Save, download or print the result with the date and assumptions if someone else must reproduce it later.
For a related crypto calculation, use the Crypto Profit and Loss Calculator to model a direct asset trade.
Run separate scenarios for alternative prices, fee tiers, power costs, reward rates, supplies or allocations. Scenario comparison is more informative than treating one set of uncertain inputs as a precise prediction. If a platform publishes a different result, inspect its definitions, rounding, mark-price method, compounding rule and included charges before deciding that either result is wrong.
Formula and calculation method
The calculator forms the final-to-initial price ratio and applies the standard 2√r ÷ (1+r) relative-value factor. Intermediate arithmetic retains additional precision, while displayed amounts are rounded only after the stated relationship is evaluated.
The calculator deliberately avoids live data so the same inputs reproduce the same answer. This also means the user is responsible for selecting an appropriate observation time and source. Record whether a price is last trade, bid, ask, mark, index, average execution or a hypothetical target. For token supply, distinguish circulating, total and maximum supply rather than substituting one for another.
Percentage inputs are divided by 100 before multiplication. Monetary results use the chosen display currency, quantities retain useful decimal precision, and time inputs follow the units shown beside each field. These conventions are repeated in the dynamic steps so a reviewer can trace the displayed answer without reverse-engineering hidden code.
How to understand the result
The large gradient value is the primary modeled result. Four colored cards expose supporting amounts such as gross value, fees, accumulated quantity, energy use, valuation, locked supply or target trades. The horizontal scale is an orientation aid generated from the scenario; it is not a market rating, safety threshold or recommendation.
To inspect another part of the same scenario, use the Crypto Portfolio Rebalancing Calculator to calculate allocation trades.
A positive profit estimate can still be unattractive after taxes, spread, slippage, funding or risk. A high staking yield can accompany token inflation, lockups or price decline. A profitable mining day can become unprofitable when difficulty, reward, uptime or electricity cost changes. A large market capitalization does not mean that the same amount of cash entered the asset or could leave it without moving price.
If the result appears surprising, first verify price units, quote currency, percentage versus decimal entry, asset quantity, time horizon and fee direction. For leveraged positions, compare the result only with the exchange's own documented liquidation engine. For DeFi and tokenomics tools, verify pool design and supply definitions. These checks are more useful than adding false decimal precision to uncertain assumptions.
Worked example and practical interpretation
When the relative token price doubles, the simplified 50/50 pool position trails holding by about 5.72% before fees.
The example demonstrates the equation rather than recommending an asset, platform, protocol, trade or target. Replace every number with values from a clearly timed source or a labeled scenario. Preserve the same definitions when comparing two results; otherwise a change may reflect a different fee, price source or time boundary rather than a meaningful improvement.
A professional review records the observation time, source, currency, included fees and any excluded costs. For a historical transaction, reconcile the estimate with statements and wallet records. For a forward-looking plan, test both favorable and adverse inputs, especially volatile price, reward, energy, difficulty and liquidity assumptions.
Accuracy, risk and professional use
This model applies only to a basic 50/50 constant-product pool. Trading fees, concentrated liquidity, ranges, incentives, gas, taxes and protocol risk are excluded.
When the analysis needs a connected check, use the Token Price from Market Cap Calculator to translate valuation into a token price.
A compact equation cannot model every exchange rule, smart-contract behavior, oracle, custody failure, network interruption, liquidation cascade, validator penalty, token emission, market-depth constraint or counterparty risk. The calculator is an education and planning aid, not a trading signal, price forecast, tax return, engineering certification or guarantee that an order or protocol will behave as modeled.
Do not enter seed phrases, private keys, wallet credentials, personal identifiers or exchange passwords. None is needed for these calculations. When a result could affect significant money, independently verify the arithmetic and the current external facts with primary documentation before acting.
