The power of time

See what happens when you start investing early and just... leave it. Fill in the numbers below, hit Calculate, and meet your future self. Takes two minutes, no login, nothing saved anywhere.

1
When does the investing happen?

The age you start putting money in, and the age you stop. Doesn't have to be exact — a rough guess works fine.

2
How much are you setting aside?

This is the bit you actually control. Pick how often, then how much each time.

The assumption we're using

This tool assumes the money sits in a diversified ETF (think: a big basket of shares, not one company) with dividends reinvested automatically, and left alone — no buying, no selling, no panic-checking the balance every week.

%
8% a year is a common long-run average used for a diversified share ETF — some years it'll be well above that, some years well below or negative. Change it if you want to test a different assumption.

At 65, set-and-forget gets you...

Worth knowing: this is a simplified education tool, not financial advice. It doesn't account for tax, inflation, fees, or the fact that real returns bounce around year to year rather than sitting neatly at one average. It's here to show how time and compounding work together — not to predict what your investments will actually do. Talk to a licensed financial adviser before making real decisions.
