So this is not a school related question, I am a trader looking to see my APY if I take an initial investment amount and make 5% on it every day of the year. I've tried the compound interest formula but it doesn't work, I only get about a 64.8% increase which I know is false. So here is what I'm looking for: I need to know the official APY of making 5% everyday on a 1,000 investment for 1 year and then the final amount your left with.
