# Skale SRB

Learn how SKALE staking rewards are calculated. SKLSRB formula covers monthly node bounty rewards, total staked SKL tokens, and annualized node yield.

SKLSRB is a benchmark representing the annualized staking rate for the SKL token.

SKLSRB is calculated and published by Staking Rewards via the [SKL Profile](https://www.stakingrewards.com/asset/skale) and [Data API](https://www.stakingrewards.com/data-api).

> **TL;DR:** SKALE staking rewards come from node bounties, paid once per node per calendar month by the SKALE Manager BountyV2 contract. The reward rate equals the bounties of the latest monthly epoch, annualized over 12 epochs, divided by total staked SKL tokens. Validator-level rates are adjusted by commission.

$$
SKLSRB = mr \* t\_e / st
$$

<table data-full-width="false"><thead><tr><th width="187">Formula key</th><th width="207">Metric name</th><th>Description</th></tr></thead><tbody><tr><td>mr</td><td>Monthly Reward</td><td>The sum of BountyReceived bounties claimed by all active nodes in the latest calendar-month epoch.</td></tr><tr><td>st</td><td>Staked Tokens</td><td>The total staked tokens amount.</td></tr><tr><td><span class="math">t_e</span></td><td>Epochs per Year</td><td>12 (one bounty epoch per calendar month, <code>EPOCHS_PER_YEAR</code> in BountyV2)</td></tr></tbody></table>

### Skale Validator Staking Rewards Rate: SKLSRB(v)

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

$$
SKLSRB(v) = vr \* t\_e \* (1 - cr) / vst
$$

<table><thead><tr><th width="149">Formula key</th><th width="216">Metric Name</th><th>Description</th></tr></thead><tbody><tr><td>vr</td><td>Validator Rewards</td><td>The BountyReceived bounties collected by the validator's nodes in the latest calendar-month epoch.</td></tr><tr><td>cr</td><td>Commission Rate</td><td>The commission rate the validators has set as a delegation fee.</td></tr><tr><td>vst</td><td>Validator Staked Tokens</td><td>The stake of the validator in the network (investment).</td></tr><tr><td><span class="math">t_e</span></td><td>Epochs per Year</td><td>12</td></tr></tbody></table>

***

### Skale Real Reward Rate (SKLSRB^R)

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

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

<table data-full-width="false"><thead><tr><th width="141">Formula Key</th><th width="158">Metric name</th><th>Description</th></tr></thead><tbody><tr><td>i</td><td>Inflation Rate</td><td>Node bounties of the latest monthly epoch, annualized over 12 epochs, divided by the circulating supply.</td></tr></tbody></table>
