How Long to Become a Millionaire?
Find how many years it will take to reach $1 million (or any goal) with monthly investing.
The path to a million
The time to reach a goal depends on three levers: how much you invest, how long you give it, and the return. Starting early and investing regularly matters more than finding a perfect return.
Make it faster
Raise your monthly amount, increase income and keep fees low. Even small increases shorten the timeline noticeably.
