Frequently asked questions
How do I use this calculator?

What method does it use?
CAGR = [(ending / starting)^(1 / years) − 1] × 100. Assumes no intermediate deposits or withdrawals.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
