Great tool, will have to show my family

Did you account for the principal also accruing value while you're saving up?

E.g. In the HY Savings account for a 1K/month passive income, you need $827,586. If you saved $1K/month, and reinvested that income until you got the $827K, it should only take you 20 years, not 23.

The error gets bigger when looking at longer time frames and higher returns.

It definitely does not.
