Commission comes before net rewards
A validator commission is usually deducted from gross staking rewards. Token inflation or a validator's advertised performance is not the user's net return.
Formula
Net APR = Gross APR × (1 − Commission %)
Compounding changes APY
APY depends on how often net rewards are compounded. More frequent compounding increases APY, but not the underlying gross APR.
Formula
Net APY = (1 + (Net APR ÷ Compounds per Year)) ^ Compounds per Year − 1
Nominal rewards omit other outcomes
Token price, slashing, downtime, MEV, tax, unbonding and provider risk remain outside a nominal staking return calculation.
