Staking yield: the honest maths, and the tax bill nobody mentions

"Earn up to 7% on your crypto" is one of the most effective phrases in the industry's marketing arsenal, because it borrows the language of a savings account for something that is not remotely a savings account. Staking is real, the yield is real, and the arithmetic quoted in the ads is real. It's the three numbers around the yield — price risk, lock-ups, and tax — that decide whether staking actually leaves you better off. Let's do the whole sum.

Where the yield comes from

Proof-of-stake networks like Ethereum, Solana and Cardano pay coin-holders for helping validate transactions — newly issued coins plus fees, shared among those whose coins back honest validators. It's network income, typically 2–7% a year depending on the chain, and every honest platform passes through roughly the same rate minus its cut. That last clause is a scam detector you can use forever: a platform advertising yields far above the network rate isn't staking better — it's doing something riskier with your coins and calling it staking. Australians who lived through the collapse of the "earn" products of 2022 don't need the mechanism explained twice.

The number that dwarfs the yield

Here's the uncomfortable arithmetic: 4% yield on an asset that moves 4% on an ordinary Tuesday. Stake A$5,000 of a coin that falls 30% and your ~A$200 of annual rewards decorates a A$1,500 loss. Staking adds return to an asset you'd hold anyway — it cannot make a falling asset profitable, and it usually adds friction at the worst moment: unbonding periods and platform queues can lock coins for days or weeks, which means you can't sell mid-panic. Our staking calculator models the compounding honestly, including the assumption ads never state: that the price holds still.

The tax bill nobody mentions

The ATO taxes staking rewards twice, in effect. Each reward is ordinary income at its AUD market value the moment you receive it — taxed at your marginal rate even if you never sell, even if the coin later halves. That value then becomes the cost base for a second, separate CGT event when you eventually dispose of the coins. On a 37% marginal rate, that headline 4% yield is roughly 2.5% after income tax — before any price move, and before the record-keeping burden of daily or weekly reward parcels, which is genuinely impractical to track by hand. This is the single strongest use case for crypto tax software, and you can sanity-check your own bracket with our tax calculator.

A sensible way to think about it

Staking makes sense as a bonus on conviction you already hold: coins you'd own regardless, staked through a platform whose custody you trust — check the AFSL tracker — or from a wallet you control, with the rate treated as a tailwind rather than the reason. It makes no sense as a reason to buy an asset, as a substitute for a savings account, or at any advertised rate that makes you feel clever. The yield is the small number in this equation. Respect the big ones.
