How Staking Rewards Actually Work: Nominal Rate, Compounding, and What Eats It

Nominal, compounded, and the gap between them

A protocol does not hand you 8 percent on 31 December. It credits a slice of it every epoch — every few minutes on some chains, every day on most staking dashboards. If each slice is restaked, the next slice is computed on a slightly larger balance, and the year ends above the headline number. That is the whole content of APY = (1 + nominal ÷ n)^n − 1: with n = 365 and a nominal 8 percent, you finish at 8.3278 percent. With monthly payouts, n = 12 and you finish at 8.30 percent. The difference between daily and monthly compounding is three hundredths of a percentage point — real, but far smaller than most yield marketing implies.

Compounding is also not automatic everywhere. Some chains restake rewards for you inside the validator balance; others credit them to a separate spendable account where they sit idle until you act. If you never claim and restake, n is effectively 1 and your 8 percent nominal really is 8 percent — you have simply left 32.78 tokens per 10,000 on the table. Check which of the two your chain does before you assume the compounded figure applies to you.

What comes off the top: commission, lock-up, slashing

Delegating to a validator costs a commission on your rewards, typically 5 to 15 percent. It applies to the reward stream, not to your principal, so it scales the nominal rate before compounding: 8 percent minus a 10 percent cut leaves 7.2 percent nominal, which compounds daily to 7.4648 percent. Your 10,000 tokens end the year at 10,746.48 instead of 10,832.78 — 86 tokens for a fee you probably never saw quoted in percentage-point terms. Zero-commission validators exist and usually cover their costs elsewhere; a commission that can be raised without notice is worth checking for.

Then there is time you are not paid for. Most proof-of-stake chains impose an unbonding period — often around 21 days — during which the tokens are neither earning nor sellable. Exit once in a year and you compound over 344 days instead of 365, which turns 7.4648 percent into 7.02 percent. Slashing is rarer but larger: a validator that double-signs or goes badly offline can cost its delegators a slice of principal, and a 5 percent slash erases more than half a year of net rewards at these rates. Neither risk appears in the number on the landing page.

Your token count rises; your share of the network can still fall

Staking rewards are usually newly issued tokens. They are not revenue paid out of profits — they are dilution, distributed to the people who stake and taken, in relative terms, from everyone who does not. That makes the honest yardstick not your token count but your share of the total supply. If the supply grows 3 percent a year and your net staking return is 7.4648 percent, your share rises by (1.074648 ÷ 1.03) − 1 = 4.33 percent. If issuance runs at 12 percent while you earn 7.4648 percent, your share falls by 4.05 percent — a shrinking slice of the network, from a wallet whose balance went up all year.

None of this touches price. A token that pays 7 percent and falls 40 percent has cost you 36 percent, and the reward stream is itself denominated in the falling asset. That is the reason to treat staking yield as a small adjustment to a position you already wanted to hold, rather than as the reason to hold it — and to compare it against the issuance schedule, the unbonding period and the validator commission before comparing it against a savings account, which it does not resemble in any respect that matters.

Frequently asked questions

Is APR the same as APY in staking?

No. APR is the nominal rate before compounding; APY is what you end the year with if every payout is restaked. At 8 percent nominal paid daily the two differ by 0.33 percentage points — 8 percent against 8.3278 percent. Interfaces use the two labels loosely, so check whether the figure assumes automatic restaking before you plan around it.

Why did I receive less than the advertised rate?

Usually four things at once: the validator commission is taken off the reward stream, the rate itself floats with how much of the supply is staked and falls as more people join, days spent unbonding or waiting to be activated pay nothing, and the advertised figure often assumed restaking you did not do. Work the chain backwards — nominal, minus commission, compounded, times the fraction of the year you were actually active — and the gap normally explains itself.

Does staking protect me if the token price falls?

No. Rewards are paid in the same token, so a 7 percent yield on an asset that falls 40 percent still leaves you down about 36 percent, and the lock-up means you may not be able to exit while it falls. Staking changes how many tokens you hold, never what they are worth.
