How to use it

  1. 1Enter your initial investment and monthly contribution.
  2. 2Enter how many years you plan to stay invested.
  3. 3Compare the conservative, moderate, and aggressive projections on the chart, and see how much of the moderate total is your own money versus growth.

Example

$1,000 to start plus $300/month for 20 years ranges from about $110,000 at a conservative 4% return to roughly $230,000 at an aggressive 10% return — the chart shows how much that difference compounds over two decades.

How it works

This runs the same monthly-compounding growth calculation three times, once each at a conservative (4%), moderate (7%), and aggressive (10%) annual return — rough, commonly cited benchmarks, not a prediction for any specific investment — so you can see the range of realistic outcomes side by side rather than relying on a single assumed rate. The contributions-vs-interest bar shows how much of the moderate scenario's total is money you put in versus growth earned on top of it.
