Cardano (ADA) Staking Calculator

Cardano runs the Ouroboros proof-of-stake protocol, secured by stake pools that produce blocks in proportion to the stake delegated to them. Holders participate by delegating ADA to a pool. Delegation is a signed on-chain declaration, not a transfer: your ADA stays in your own wallet, remains fully spendable at any moment, and is never bonded or escrowed.

Rewards come from a mix of transaction fees collected in each epoch and a controlled release from the protocol reserve. They are shared between the pool operator and delegators after the pool takes its fees.

Every stake pool charges two things:

• A fixed fee — taken per epoch before rewards are split. The protocol sets a floor of 170 ADA per epoch, and most pools use exactly that.
• A margin — a percentage of what remains, set by the operator. Competitive pools typically run low single digits.

Cardano's epoch is five days, and the reward cycle is pipelined. After you first delegate, expect roughly 15 to 20 days before the first payout arrives, because your stake must be snapshotted, become active, and then earn across a full epoch. This delay applies only to your first delegation — after that rewards land every epoch.

Rewards compound automatically. They are paid to your reward account and counted as part of your delegated stake in the next snapshot without any action on your part.

Native delegation — Delegate from a self-custody wallet such as Lace, Eternl, or a hardware wallet. There is no minimum, no lockup, and you keep full custody and spendability. Registering a stake key requires a small refundable deposit of 2 ADA, returned when you deregister. This is the standard route and earns the full pool rate minus the pool's fees.

Exchange staking — Some centralized exchanges delegate on your behalf. It removes the setup step, but the exchange holds your keys and keeps a share of the rewards. Given that native delegation on Cardano involves no lockup and no slashing risk, the case for using an exchange is weaker here than on most other networks.

Pool choice matters more than route. Because every delegator earns the same protocol rate, your realized yield is driven almost entirely by which pool you pick — specifically its fees, its reliability at producing assigned blocks, and whether it is oversaturated.

The calculator above uses the live Cardano reward rate, so you can compare what a given amount of ADA earns across time horizons and providers with their actual fees applied.

Cardano staking carries less downside than most proof-of-stake networks, but a few things still affect your return:

• No slashing — Cardano does not implement slashing. Your delegated ADA cannot be confiscated because of pool misbehaviour, which removes the main tail risk present on Cosmos or Ethereum.
• Pool saturation — Each pool has a saturation cap. Once a pool exceeds it, rewards per delegator fall, and stake beyond the cap earns proportionally less. Checking saturation before and after delegating is the single easiest way to avoid leaving yield on the table.
• Pool reliability — A pool that misses assigned blocks produces fewer rewards to share. Small or poorly maintained pools can underperform their expected rate for long stretches.
• Fee structure — The 170 ADA fixed fee per epoch weighs more heavily on small pools, since it is deducted before the split regardless of how much the pool earned.
• Price volatility — Rewards are paid in ADA, so your realized return in fiat terms depends on the token price as well as the reward rate.
• Tax treatment — Staking rewards are typically taxable as income when received. Consult a local tax professional.
