APR vs APY in crypto: understand the rate and the return

Read what the percentage is measuring

A percentage needs a numerator and a base. For yield, the numerator can be interest, trading fees, staking income or token incentives. The base can be deposited principal or another documented measure of capital.

APR commonly expresses a nominal annual rate without automatically including compounding. APY describes the effect of compounding under stated assumptions. Crypto products can use labels differently, so the source's definition matters more than the acronym alone.

A realised return measures what happened over an actual period. It requires the relevant cash flows and valuations. It can differ from either displayed rate because conditions changed or the user's activity did not match the assumed reinvestment.

Before comparing two rates, write down the asset, period, gross/net treatment and included income. That brief description often explains a difference that the percentage hides.

Calculate a constant-rate teaching example

Choose a nominal 6% annual rate, monthly reinvestment and a starting balance of 1,000 units. Assume the rate stays unchanged and there are no charges or external flows.

The monthly rate is 0.06 divided by 12, or 0.005. After one month the model balance is 1,005. In the next month, the same fraction applies to 1,005, so the model earns on previously added income too.

After twelve months the model gives 1,000 multiplied by (1 + 0.06/12) to the power of 12, approximately 1,061.68. The corresponding APY is about 6.1678%.

These are chosen arithmetic conditions, not a quoted staking or deposit offer. If reinvestment is unavailable, the rate changes or charges apply, the realised path differs. The formula makes those assumptions explicit.

A variable rate is not one fixed year-long input

A lending rate can change with pool use. Trading-fee income changes with volume and active liquidity. Incentives can change with emissions and the reward asset's price.

A provider can annualise a recent window to express current conditions. That says what a continuation assumption implies; it does not turn a short observation into a full year of results.

For varying periods, compounding follows the sequence of actual applicable rates and reinvestment. Simply choosing one large recent percentage and applying it unchanged can produce an unsupported projection.

Keep the window and update time visible. When a chart changes methodology or reward components, a visually continuous series can still contain a break in meaning.

More tokens can still mean lower currency value

Check how income is actually reinvested

Some positions incorporate income automatically. Others accrue a separate claim that the user must collect and reinvest. Rewards paid in a second token do not automatically increase the original deposited asset.

For a manual claim, include transaction costs and any conversion needed before reinvestment. A strategy that assumes frequent compounding can overstate the result if those costs or actions are omitted.

Read whether product fees are already deducted. Adding gross incentives to a net base rate can be meaningful only when the source definitions and periods support that combination.

For an exchange-rate-style LST, a stable token count can represent changing underlying value. Learn the product's accounting instead of interpreting an unchanged wallet quantity as zero income.

Separate asset growth from currency performance

Choose a teaching holding of 100 tokens initially worth 100 currency units each: a total of 10,000. After a period, suppose the holding grows to 106 tokens while the market price falls to 80.

The end value is 8,480. The token quantity increased by 6%, but the chosen currency value fell by 15.2% before any other flows or costs. Both statements can describe the same holding.

A stablecoin position still needs the token's market value and redemption mechanism considered, even when an interface uses a one-unit display convention. Multi-token incentives also need a consistent valuation time and source.

This is why a token-denominated yield and a complete investment return should be named separately. The LP accounting guide shows another worked example.

Build a like-for-like rate comparison

Use one row per source or product. Record the reported rate, asset, date, lookback window, components, fee treatment and compounding method. Keep unknown fields visible.

For a validator comparison, obtain a documented delegator-yield measure rather than deriving a substitute from credits or sampled account balances. A total operator-plus-delegator income rate describes another recipient set.

For your own holding, keep a cash-flow and value ledger to calculate actual period performance under an explicit method. A source estimate helps describe its stated conditions; the ledger explains what happened to the position.
