What is compound interest?
Compound interest means you earn returns not just on your original investment, but on your accumulated gains as well. Albert Einstein allegedly called it the "eighth wonder of the world" - and for good reason. Over long periods, the growth curve becomes exponential.
Why does time matter so much?
Starting early is the single most powerful thing you can do for your portfolio. At a 7% return, someone who invests $500/month from age 25 has about $1.31 million at 65, while someone who invests $1,000/month from 35 has about $1.22 million - even though the late starter puts in $120,000 more.
Should I adjust for inflation?
Yes - inflation erodes purchasing power over time. A dollar today will buy less in 30 years. Toggling on the inflation adjustment shows your portfolio's value in today's dollars, which is a more realistic measure of future wealth.
