What is APY in staking and how are rewards calculated?

The APY in staking is the annualized percentage that estimates the rewards a participant can accumulate by contributing to the validation of a blockchain network. This indicator appears on any platform that offers staking, including the section Earn from Bit2MeAnd it's usually the first figure any user checks before deciding where to allocate their crypto assets. However, few people understand what's really behind that number or why it changes from week to week. Understanding how APY staking is calculated gives you the ability to interpret those figures yourself, instead of blindly comparing them across platforms.

In this guide, we'll review what APY measures, how it's calculated from network fees, total staking, and block rewards, and why this figure is never fixed or guaranteed. We'll also look at the factors that explain why APY varies between networks such as Ethereum, Cardano o Polkadotand how to critically interpret the data displayed by any platform. If you're still not clear on what this entails... staking As a participation mechanism, this piece complements our general guide on staking and Earn, where we explain the fundamentals of validation in networks of Proof of Stake (PoS).

In the European Union, the regulation MiCA (Markets in Crypto-Assets)The regulation, in force since 2024, governs the provision of services related to crypto assets, including staking, by authorized providers. This framework does not eliminate the risk associated with the volatility of crypto assets, nor does it make the APY a guaranteed figure; it simply establishes transparency and protection requirements for those offering these services within the European Union.

What is APY in staking and why is it the most frequently consulted metric on Earn?

APY stands for Annual Percentage Yield, meaning the annualized percentage of rewards, although in the context of staking it's more accurate to speak directly of the annualized percentage of rewards. It's a projection: it takes the rewards that a protocol distributes over a short period, usually per block or epoch, and extrapolates them to twelve months, assuming that these rewards are continuously reinvested in the asset itself. Those looking for general information about APY for cryptocurrencies will usually first encounter this figure on a staking platform, alongside each asset available for participation.

It's important to distinguish APY from another related term, APR (Annual Percentage Rate), which represents a similar projection but without assuming the compounding of rewards. The difference may seem technical, but it changes the final number: an APY is usually somewhat higher than an APR calculated on the same base rewards because it incorporates the effect of accumulating rewards on top of those already earned. When a platform displays both figures for the same asset, this numerical difference is precisely a reflection of the assumed capitalization.

For a participant already familiar with staking, APY serves as a quick benchmark for comparing assets, not as a guaranteed figure. You can always check the current conditions for each asset before deciding where to participate on the platform. This comparison is only meaningful if you understand that each protocol calculates its APY using its own rules, which we will explain in the following sections.

How does APY differ from staking a traditional bank interest rate?

When someone first hears “annual percentage,” they naturally associate it with the interest rate offered by a bank account. However, the mechanism behind staking rewards is conceptually different. A bank pays you an interest rate because it takes your money on deposit and invests it in other financial products on its own, returning a portion of that profit to you as a contractual obligation backed by the bank itself and, in the European Union, by Deposit Guarantee Funds.

Staking rewards don't work that way. When a participant allocates crypto assets to network validation, they aren't lending that money to an entity that returns it with a bonus: they're contributing to the network's ability to securely process and confirm transactions. The protocol itself, not a bank, issues new units of the asset or redistributes network fees among those participating in that validation, and this distribution is what translates into rewards for the user.

This difference has significant practical consequences. There is no deposit guarantee fund to cover crypto assets staked, and the protocol has no contractual obligation equivalent to that of a bank: the network simply follows its own issuance and distribution rules, which can change with protocol updates. Therefore, in Bit2Me Academy We always talk about staking rewards and not an equivalent banking concept: the underlying economic mechanism is different from the traditional banking system.

How is APY staking calculated? Network fee, total stake, and block rewards

At a high level, the calculation of APY in staking combines three elements that each Proof of Stake protocol manages differently. The first is block rewards: each time the network validates a new block or closes an epoch, the protocol issues or redistributes a certain number of units of the asset among the validators who participated in that process. This annualized flow of rewards is the basis upon which all subsequent calculations are built.

The second element is total staking, that is, what proportion of the total asset supply is currently allocated to network validation. This data is crucial because block rewards are distributed among all participants: if total staking increases, the same reward stream is divided among more staked units, and the percentage corresponding to each individual participant tends to decrease. If total staking decreases, the opposite occurs, and the estimated APY increases to incentivize more users to participate in validation.

The third element is the network or validator fee. Many networks charge a fee on the gross rewards before distributing them, either as part of the protocol itself or as a fee for whoever operates the validator node on behalf of the user. This fee is subtracted from the final calculation, so the APY that a participant actually receives is always net of these costs.

Why is the APY never fixed or guaranteed?

The APY in staking is not a fixed or guaranteed rate: it varies over time depending on network conditions and each protocol's issuance policy. This occurs for several reasons that should be considered before focusing solely on the number displayed by a platform at any given time.

The first reason is that total staked holdings are constantly changing. Every day, new participants allocate crypto assets for validation or withdraw those they already have allocated, and this movement automatically redistributes the flow of block rewards among a different number of staked units. The second reason is that many protocols adjust their issuance rate algorithmically, aiming to maintain a target level of participation in the network; when that target is exceeded or not reached, the issuance, and therefore the estimated APY, is recalculated.

Specific network events also have an impact, such as protocol updates, changes in validator fees, or penalty situations known as slashing, which temporarily reduce the rewards available to participants. Therefore, any specific APY figure you see on a platform should be understood as a snapshot of the current moment and not as a future commitment. No platform, including Bit2MeIt can guarantee that the APY remains stable over time, because it depends on variables external to the service itself.

Factors that cause APY to vary between different networks and protocols

In addition to varying over time within the same network, APY also differs significantly between different networks and protocols. These are the factors that explain this difference:

• The specific consensus mechanism: direct staking on the base network is not the same as delegated staking through a pool or liquid staking with a derivative token.
• The emission rate specific to each protocol, which can be fixed, decreasing, or dynamically adjusted according to the total participation.
• The commission charged by the validator or node operator, which varies from one provider to another within the same network.
• The total level of staking participation of that specific network at a given time.
• The existence or not of lock-up periods that condition when the assigned crypto assets can be withdrawn.

These differences explain why comparing the APY of two different networks, such as Ethereum versus Cardano or Polkadot, is not a straightforward comparison like comparing two identical products. Each protocol defines its own issuance rules, fee structure, and participation level, so a higher APY on one network does not automatically imply a better offer for the user: liquidity, project maturity, and exit conditions must also be considered before allocating crypto assets to any of them.

How to critically interpret the APY that a platform advertises?

Seeing a large number next to an asset's name might tempt you to compare platforms based solely on that figure, but it's worth checking what's really behind it. A first point to verify is whether the displayed APY is gross or net of fees: some platforms show the figure before deducting the validator's fee, which inflates the number compared to what the user actually receives.

A second point is the frequency of data updates. The APY in staking changes with the total network participation, so a figure that isn't updated regularly can become outdated compared to the actual protocol conditions at that time. It's also worth checking whether the calculation assumes automatic accumulation of rewards or if, on the contrary, they would have to be claimed and manually reassigned to reach that annualized figure.

Finally, it's reasonable to question the source of the data: whether the platform explains how it calculates the displayed APY, or if it simply reproduces a number without context. You can See rewards in Earn At any time, you can compare the current conditions, asset by asset, and use that comparison as a starting point, not as an automatic decision. No advertised APY replaces reading the full protocol conditions or guarantees a specific outcome in the future.

Good practices before looking at the APY to choose where to participate

With all of the above in mind, these are the practical steps to follow before making a decision based on an asset's APY:

1. Check if the displayed figure is net of network or validator fees, not just the gross figure.
2. Check the date or time of the last data update within the platform.
3. Evaluate the periods of lock-up or liquidity associated with that specific asset, not just the advertised percentage.
4. Compare the APY between several assets within the same platform before comparing between different platforms.
5. Track the data regularly instead of memorizing a specific figure as if it were permanent.

Following this process doesn't eliminate the variable nature of APY, but it does reduce the likelihood of making a decision based on a figure taken out of context. A deep understanding of APY staking is what separates someone who simply follows the data from memory from someone who interprets it critically before allocating their crypto assets to any network. The next time you see a striking percentage next to an asset, you'll have the tools to ask yourself what exactly is behind that number.
