At 7% a year, money doubles roughly every 10.3 years— the "rule of 72". That's why the curve bends up: the last few years do more work than the first ten.
Illustration only, not a projection or advice. Real markets don't grow in a straight line — returns vary year to year, include losing years, and no rate of return is guaranteed. Compounding also works against you with fees and debt.
The lesson under the tool
What the curve is showing.
- 01
Growth on growth
Compounding just means your growth itself starts growing. Year one, your money earns. Year two, your money AND year one’s earnings earn. Left alone long enough, the earnings overtake the deposits — that’s the bend in the curve.
- 02
Time beats amount
Try it above: $50 a week for 30 years usually beats $150 a week for 10. Starting early is the one advantage that can’t be bought later — which is why the boring move (start small, now) wins so often.
- 03
Consistency is the engine
The schedule matters more than the timing. Missing the "perfect" entry costs less than missing years of contributions. This is exactly what Auto-Invest automates: same amount, same day, no willpower required.
