About this calculator
Liquid staking changes the usual trade-off between earning staking rewards and keeping capital usable elsewhere. In this framework, an ETH position is represented by a liquid staking token, and that token can still be deployed in DeFi while continuing to accrue its base staking return. The calculation therefore matters because it shows how a single principal base can support two distinct yield streams at the same time. Rather than treating the result as one undifferentiated number, the model separates the staking component from the DeFi component so the source of return remains visible.
That distinction is useful when comparing stacked strategies with simpler alternatives such as plain staking or passive holding. A combined figure can make the extra return from the DeFi layer easy to compare, but it also clarifies that a higher headline APY is not a free upgrade. The staking layer carries its own risks, while the lending or collateral layer introduces another set of exposures on top. Historically, traders often interpret stacked yield as more efficient capital use, yet the same structure also concentrates more moving parts into one position. This calculator is designed to quantify the return side of that trade-off while keeping the two layers analytically separate.
How the calculation works
The calculator starts with principal, expressed as the initial ETH value used in the strategy. In the simplified model, that same principal is the base for both yield layers. The first layer is the liquid staking yield, which represents the staking return earned by holding an LST such as stETH or rETH. The second layer is the DeFi APY, which reflects the additional return generated by supplying that LST into a lending market or using it as collateral in a yield-bearing setup. To estimate a combined annualized return, the model approximates combined APY as the sum of the staking yield and the DeFi yield when both apply to the same principal. The holding period then converts that annualized figure into a period return, allowing the calculator to estimate ending value and total gain over less than or more than one year. Instead of presenting only a final balance, the output also breaks total gain into staking-layer gain and DeFi-layer gain. That split makes it easier to see whether most of the result comes from the base LST position or from the added DeFi layer.
When to use this
This calculator is most useful when comparing a plain liquid staking position with a stacked setup that adds a lending or collateral layer. In that context, it helps isolate how much extra return the DeFi component contributes on top of the base staking yield. It is also relevant when evaluating whether a relatively small APY increase materially changes the economics of the position once additional protocol and depeg risk are acknowledged. By separating the sources of return, the model gives a clearer view of what the extra complexity is actually paying for.
Its usefulness is lower for strategies with rapidly changing rates or reward structures spread across multiple tokens, because the simplified estimate assumes stable annualized inputs over the selected period. It also does not attempt to capture several important mechanics that can dominate real outcomes, including liquidation risk when collateral is borrowed against, borrowing costs, or compounding effects from reinvesting rewards. In practice, traders often use this type of calculator as a first-pass comparison tool rather than a full position simulator. It is best read as a clean baseline for stacked yield, not as a complete map of every cash flow and risk embedded in a live DeFi strategy.
Worked example
Consider a position worth $10,000 in ETH equivalent. That ETH is held through a liquid staking token earning 3.2%, and the same token is then used in a DeFi setup that adds another 2.0% annualized return. The holding period is 1.5 years. In the calculator’s simplified additive model, the two yield layers are combined first: 3.2% + 2.0% = 5.2% combined APY. Applied to the $10,000 principal, that implies an annual gain of about $520. Over 1.5 years, the estimated gain becomes $780, producing an ending value of roughly $10,780.
The split between layers shows where that return comes from. The staking portion contributes $480, while the DeFi layer contributes $300, for a total gain of $780. Read this way, the example is not just a headline yield calculation; it is a decomposition of the strategy. The base LST position generates most of the return, and the DeFi layer adds a smaller incremental amount on the same principal. The final output is therefore 5.2% combined APY, $10,780 value after the period, and a clearly separated view of staking versus DeFi contribution.
Common mistakes
A frequent mistake is treating the combined APY as if it were fixed or guaranteed. In practice, both the staking yield and the DeFi yield can change over time, so a single combined figure is better understood as a simplified estimate than a locked outcome. Another common error is ignoring the structure of the DeFi layer itself. If the LST is used as collateral in a borrowed position, the return profile may be tied to liquidation risk, which this calculator does not model. Traders also sometimes assume the liquid staking token will always trade at par with the underlying asset, even though depeg risk can affect realized value.
There is also a modeling mistake: reading the output as a full simulation rather than an additive approximation. The calculator does not automatically reflect compounding, fees, or the price volatility of any reward tokens unless those effects are explicitly built into the strategy assumptions. Finally, some users interpret stacked yield as if one layer somehow offsets the other layer’s risk. In reality, the exposure from staking and the exposure from the DeFi protocol stack rather than cancel out. The result may look efficient on the return side, but the risk profile becomes more layered at the same time.
Related concepts
This calculator sits close to lending effective APY because the DeFi component often comes from supplying an LST into a lending market or using it as collateral in a yield-generating structure. Understanding the effective return of that layer helps explain why the combined figure can differ from the staking rate alone. It also connects directly to compound interest. The simplified model here is additive, but real-world outcomes can diverge when rewards are periodically reinvested or when quoted rates assume compounding in different ways.
APR-to-APY conversion is another nearby concept. Staking protocols and DeFi markets do not always quote returns on the same basis, so comparisons can become distorted if one rate assumes compounding and the other does not. On the risk side, the calculator should be read alongside ideas such as leverage and drawdown, especially when the LST is posted as collateral. Even if the strategy is not highly leveraged in a conventional sense, collateral usage can still create path-dependent outcomes when asset prices move or when the LST deviates from parity. Taken together, these related concepts help frame combined yield as more than a single percentage: it is a layered return structure with layered assumptions behind it.
Frequently asked questions
How do you calculate combined yield from liquid staking and DeFi?
In this simplified model, the combined yield is estimated by adding the liquid staking yield and the DeFi APY together because both are treated as applying to the same principal. The calculator then uses the holding period to convert that annualized rate into an estimated gain and ending value, while also separating the staking contribution from the DeFi contribution.
Is liquid staking yield the same as staking APY?
Usually yes in this context, because the liquid staking token represents a staked position and earns the underlying staking return. However, the quoted figure can differ depending on whether a protocol presents it as APR, APY, or a variable reward estimate. That is why comparing rates across platforms requires attention to how each number is defined.
Does using stETH or rETH in DeFi increase total APY?
It can increase the headline APY by adding a second yield layer on top of the base staking return. In analytical terms, the LST continues earning staking yield while the DeFi position contributes an additional return stream. The higher combined figure, however, reflects added complexity and additional protocol, depeg, and operational risk rather than a risk-free improvement.
Why does the calculator split staking gain and DeFi gain?
The split makes the source of return easier to interpret. Instead of showing only one combined number, the calculator identifies how much gain comes from the base liquid staking position and how much comes from the lending or collateral layer. That separation is useful when comparing stacked strategies with simpler alternatives or judging whether the extra layer is materially changing results.
Does this calculator include compounding?
Not necessarily. The calculator uses a simplified annualized estimate unless the underlying strategy explicitly compounds rewards. That means the result is best read as a baseline approximation rather than a full reinvestment model. If rewards are periodically redeployed, actual outcomes can differ from the additive estimate shown by the calculator.
What risks are not shown in combined yield calculators?
Common omissions include slashing, LST depeg risk, smart contract risk, liquidation risk, and changes in reward rates over time. The calculator also does not fully capture fee drag, borrowing costs, or the effect of volatile reward tokens unless those are built into the assumptions. As a result, the displayed yield should be read as a return estimate, not a complete risk model.
