# Hedera SRB

HBARSRB is a benchmark representing the mean, annualized staking rate across all active Hedera validators.

HBARSRB is calculated and published by Staking Rewards via the [Hedera Profile](https://www.stakingrewards.com/asset/hedera-hashgraph) and [Data API](https://www.stakingrewards.com/data-api).

> **TL;DR:** Hedera staking rewards combine fixed daily HBAR rewards plus transaction fees, annualized over 365 days and divided by total staked HBAR tokens. The rate is non-compounded and assumes 100% validator efficiency.

$$
HBARSRB = ((dr+ df) \* t\_y)/st
$$

<table data-full-width="false"><thead><tr><th width="154">Formula key</th><th width="194">Metric name</th><th>Description</th></tr></thead><tbody><tr><td>dr</td><td>Daily Rewards</td><td>Fix reward rate per staked HBAR per day.</td></tr><tr><td>df</td><td>Daily Fees</td><td>The total number of HBAR tokens paid as transaction fees on the network.</td></tr><tr><td>st</td><td>Staked Tokens</td><td>The total number of tokens that are currently being staked across Hedera.</td></tr><tr><td><span class="math">t_y</span></td><td>Year Constant</td><td>365d</td></tr></tbody></table>

* HBARSRB takes into account all accumulated rewards, whether they have been claimed or remain unclaimed.
* HBARSRB operates on a non-compounded basis, meaning it excludes returns generated from the reinvestment of rewards.
* HBARSRB is based on an assumption of 100% validator efficiency. For a HBARSRB adjusted according to individual validator performance, please refer to HBARSRB(v).

#### Slashing

{% hint style="info" %}
Although Hedera Hashgraph operates as a PoS system, it does not involve slashing or bonding, so nodes do not face the related loss of liquidity.

### Hedera Validator Staking Rewards Rate: HBARSRB(v) <a href="#hedera-validator-staking-rewards-rate-hbarsrb-v" id="hedera-validator-staking-rewards-rate-hbarsrb-v"></a>

Staking Rewards calculates the HBARSRB for each validator based on their individual performance and commission rate.

$$
HBARSRB(v) = HBARSRB \* (1*p)*(1-cr)
$$

<table data-full-width="false"><thead><tr><th width="129">Formula key</th><th width="176">Metric name</th><th>Description</th></tr></thead><tbody><tr><td>p</td><td>Performance</td><td>The percentage of successfully validated blocks.</td></tr><tr><td>cr</td><td>Commission Rate</td><td>The percentage commission rate the validator has set as a delegation fee for all delegators.</td></tr></tbody></table>

**Observation Period:**

1. HBARSRB is determined based on the latest generated block at the point of evaluation.
2. This data is then annualized for a comprehensive year-long projection.

**Calculation**

The calculation happens every 2 hours and is immediately published via [Data API](https://www.stakingrewards.com/data-api).

**Limitations**

HBARSRB employs a 365-day convention for annualizing current block provisions and daily fees. This convention remains consistent and does not accommodate adjustments for leap years.

***

### HBAR Real Reward Rate (HBARSRB^R) <a href="#hbar-real-reward-rate-hbarsrb-r" id="hbar-real-reward-rate-hbarsrb-r"></a>

The real reward rate calculates the HBARSRB adjusted for inflation in the network.

$$
HBARSRB^R = (1+HBARSRB) /(1+i)-1
$$

<table data-full-width="false"><thead><tr><th width="150.33333333333331">Formula key</th><th width="265">Metric name</th><th>Description</th></tr></thead><tbody><tr><td>i</td><td>Inflation Rate</td><td>The annual provisions adjusted by the actual block time of the last 24h and divided by the total token supply in the network.</td></tr></tbody></table>

\
**Inflation Rate Behaviour**

The release of HBAR tokens into circulation is controlled by a predefined schedule.
