What DeFi Yield Farming Calculator does and how it behaves

A liquidity position can earn rewards while still underperforming the same tokens held outside a pool. This calculator combines deposited value, token price changes, farming rates, and holding time to compare LP value, estimated rewards, APR, and compounded APY. Its impermanent loss figure is a relative result: it measures the difference between providing liquidity and simply holding the original assets. It does not necessarily mean the position lost money in currency terms.

How the result is produced

1

LP value and impermanent loss

The calculator uses the starting liquidity position and subsequent token price changes to estimate the value represented by the LP position. It then compares that amount with the value of retaining the originally deposited tokens. The percentage difference is impermanent loss. This comparison is meaningful only when the selected pool assumptions match the actual pool.

Yield and compounding

APR represents an annualized return without reinvesting interim earnings. APY represents a compounded annual return, so it depends on how often rewards are assumed to be reinvested. The calculator applies the stated rate and duration to estimate farming income, then presents that income alongside LP value and impermanent loss rather than treating headline yield as the entire result.

Good uses

  • Compare two farms whose advertised rates differ but whose token pairs carry different impermanent loss exposure.
  • Estimate whether projected liquidity incentives could offset underperformance against holding the deposited tokens.
  • Translate a protocol's APR into an APY under a chosen reinvestment schedule before committing liquidity.

Limits and checks

  • Impermanent loss depends on the pool design, asset weights, and price movement. A standard equal-weight estimate may not describe concentrated-liquidity, stable-asset, or weighted pools.
  • APR and reward-token prices can change during the holding period, so an annualized estimate is not a promised return.
  • Transaction fees, gas costs, slippage, taxes, failed reinvestments, and smart-contract losses may be outside the displayed result.

Common questions

Why can the farm show positive earnings but still trail simply holding the tokens?

Rewards add value, but the pool continually changes the quantities of the two assets represented by the position. After a large relative price move, the LP position can be worth less than the untouched deposit would have been. If that difference exceeds fees and incentives earned, the farm has positive income but negative performance against the holding benchmark.

Does the calculated APY predict what I will earn over a full year?

No. APY annualizes a rate under a compounding assumption. It does not ensure that the farm's APR, reward emission, pool fees, token prices, liquidity, or reinvestment costs will remain constant. Use it to compare stated scenarios, not as a forecast or guarantee of realized returns.
