Learn moreContributions first, growth later
The path to $1 million starts slow — early on, your contributions do most of the work. But as the balance grows, compounding takes over and growth outpaces what you add. The two biggest levers are how much you invest and how early you start.
How it’s calculated & sources
We compound your current savings monthly at the expected return and add your contribution each month until the balance reaches the target, then report the time, total contributed, and growth.
Benchmark: for most savers, reaching $1M is mostly contributions in the early years and mostly growth in the later ones.

Worked example
Starting at $25,000 and adding $800/month at 7% reaches $1 million in about 27 years — with growth eventually contributing more than your deposits.
Frequently asked questions
What return should I assume?
A diversified long-run estimate is ~7% nominal. Use a lower figure to be conservative, or a real (~5%) rate to see the result in today’s dollars.
How can I get there faster?
Increase contributions (especially raises), start sooner, and keep fees low. Time and savings rate matter far more than picking hot investments.
