Staking rewards question

Hi all I recently bought some ETH and it says you can stake it on Coinbase for 2.5%apy

I have never staked before and wondered how the pay outs work as an example ?

I have have $5000 eth staked at 2.5% that's $125 per year divided by the month is like $10 per month . Have I got this right as it seems not really worth doing ?
