Frequently Asked Questions
What is this useful for?
This models regular investing — a 401(k), SIP, RRSP or any account you contribute to monthly — showing how contributions plus compounding growth add up over time.
What if my rate of return is 0%?
With a 0% return, the future value is simply the sum of all contributions, since there's no growth to compound.
