The power of one more contribution
Adding to your investments every month compounds quietly in the background. The extra you contribute matters, but the growth on that extra over many years is what really moves the number. This compares your current path with a slightly more aggressive one.
Questions people ask
Does investing a little more each month really matter?
Yes — because of compounding, extra contributions made early have years to grow. A modest monthly increase can translate into a large difference over decades.
What return should I assume?
Long-run diversified portfolios have historically returned mid-single digits to around 7% after inflation, but the future isn't guaranteed. Try a few rates to see how sensitive the outcome is.
Is this a forecast of my actual returns?
No. It's an illustration based on a steady assumed return. Real markets fluctuate, so treat it as a way to understand the shape of compounding, not a promise.
