Casper rewards calculator
Estimate what staking with a validator earns, after its commission.
Estimate your rewards
Any active validator: about 10.09% a year
What each validator's stake earned per CSPR over the last 84 eras, after the 2/8 of era rewards that go to the network's sustain fund, before the validator's commission. Casper adds rewards to the stake every era.
Your estimate
About 5.04% a year. That is 10.09% a year less this validator’s 50.0% commission, which it sets on-chain and takes from rewards before paying its delegators. Enter an amount to see what it earns.
An estimate, not a promise. It assumes the network keeps paying what it pays now and that the validator performs like an average one. Real rewards move with luck, uptime, fees and network changes. Not financial advice.
How this is worked out
Each era's switch block lists every validator's reward; 75% of it is paid to the validator's stake. Over the last 84 eras that came to 0.0000230257 CSPR per CSPR staked an era, before commission: 10.6% a year with rewards restaked.
- Eras counted
- 84
- Paid to stake
- 75% of era rewards
- The rest goes to the network's sustain fund (chainspec rewards_handling)
- Minimum delegation
- 500 CSPR
- Delegators per validator
- At most 1,200
Assumptions
- Rates are what each validator's stake earned over the last 84 eras (about 7d 0h), so they already reflect its performance.
- Casper adds rewards to your stake every era; the estimate here is simple interest, so it reads a little low over long periods.
- Delegations start earning 2 eras after they are made, and undelegating takes 7 eras.
