How to Use This Calculator
  1. Enter Stake required (tokens), Token price ($), and Staking APR (%).
  2. Set Hardware/VPS monthly ($), Bandwidth monthly ($), and Electricity monthly ($).
  3. Adjust Expected uptime (%), Annualized slashing risk (%) as needed.
  4. Review the Net monthly profit ($) ($) result.
  5. Use Net APR after costs (%) (%) and Stake value ($) ($) to inform your decision.

What each input means

Stake required (tokens)
Minimum tokens required to run a validator (Ethereum = 32 ETH).
Token price ($)
Current price of the staked token in USD.
Staking APR (%)
Annual percentage rate for staking rewards.
Hardware/VPS monthly ($)
Monthly cost for server/VPS (e.g., Hetzner, AWS, or self-hosted amortized).
Bandwidth monthly ($)
Monthly internet/bandwidth costs for node operation.
Electricity monthly ($)
Monthly electricity cost (for self-hosted hardware).
Expected uptime (%)
Expected validator uptime. Lower uptime = less rewards + potential penalties.
Annualized slashing risk (%)
Estimated annual probability-weighted slashing loss (typically very low).
Initial setup cost ($)
One-time hardware purchase or setup costs.
Time horizon (months)
How long you plan to operate the validator.

What each result means

Net monthly profit ($)
Monthly staking rewards minus operating costs and slashing risk.
Net APR after costs (%)
Effective annual return on staked capital after all operating costs.
Stake value ($)
USD value of the required stake.
Monthly rewards ($)
Monthly staking rewards adjusted for uptime.
Monthly operating cost ($)
Total monthly hardware, bandwidth, and electricity costs.
Annual rewards ($)
Total annual staking rewards (uptime-adjusted).
Annual operating cost ($)
Total annual operating expenses.
Break-even (months)
Months to recoup initial setup costs from net profits.
Total tokens earned
Total staking reward tokens earned over the time horizon.
Total profit ($)
Net profit over the full time horizon after setup and operating costs.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Stake required (tokens) = 32, Token price ($) = 2000, Staking APR (%) = 4, Hardware/VPS monthly ($) = 50 = 10 input(s) provided
  2. Calculate Net monthly profit
    Net monthly profit = monthlyRewardUsd - monthlyOpCost - monthlySlashingRisk
    106.93 = $106.93
  3. Calculate Net APR after costs
    2.005 = 2.005%
  4. Calculate Stake value
    Stake value = stakeRequired * tokenPrice
    64000 = $64,000
