You can find the current APR on the staking page. Lido's APR is currently lower than Ethereum's APR due to the activation queue for ETH validators as well as Lido's staking rewards fee. Lido's APR will grow as the rate of active stakers on Lido becomes higher, but will not exceed Ethereum's APR. With Lido, you receive staking rewards within 24 hours of your deposit being made, without waiting for validator activation.
