About this calculator
Estimate returns by applying APY as an effective annual yield over the selected days, then subtract entered gas costs and impermanent-loss allowance. APY already includes compounding; frequency is used only for the APR-to-APY comparison. Token prices, pool changes, smart-contract risk and changing yields are not modeled.
Worked example
calculated with the default values below
Principal deposited 10,000 $ · Annual percentage yield 12 % · Days deposited 365 days · Annual percentage rate (base) 11.3 % · Compounding per year Daily · Gas and entry fees 20 $ · Impermanent loss allowance 0 % Final balance 11,200.00 $ · Yield earned 1,200.00 $ · Profit after costs 1,180.00 $ · Return over your period 11.800 % · APY implied by the base APR 11.96 % · Average daily yield before costs 3.2877 $ · Impermanent loss allowance 0.00 $

Formula and variables
Gross = principal × (1 + APY/100)^(days/365); implied APY from APR = (1 + APR/(100n))^n − 1

- Impermanent loss (%)
Gross balance = principal × (1 + APY/100)^(days/365). APY is effective and already includes compounding; compound the base APR separately only to show its implied effective annual yield.
Frequently asked questions
Why does the base APR differ from the quoted APY here?
The balance applies the entered APY as an effective annual yield over the selected days; it does not compound that APY again at the selected frequency. The APR comparison separately shows the effective annual yield implied by compounding the base APR. The impermanent-loss field is a user-entered allowance, not a forecast of actual pool loss; gas is subtracted from modeled profit.
