How the Investment Calculator Works

Project your wealth growth from starting capital, regular deposits, expected returns and inflation.

1

Set your starting point and expectations

Enter your initial investment, the annual return you expect, and how often returns compound — daily, monthly, quarterly or yearly. More frequent compounding earns a little more.

2

Add your contributions and time horizon

Choose how much you invest each month or year and whether deposits land at the start or end of the period, then set your investment timeline. Every deposit compounds from the day it is added.

3

See growth and inflation impact

The result shows your future portfolio value, total contributions, investment returns, and what your balance is worth in today's money after inflation. Use the year-by-year table to track growth at each milestone. Need to measure returns on money already invested? Try the ROI Calculator.

Frequently Asked Questions

How does this investment calculator work?
It projects your portfolio month by month, growing the balance at your expected annual return, adding each contribution at the start or end of the period, then compounding. It shows the future value, how much you invested, and how much is investment return.
What is the inflation-adjusted value?
It restates the future value in today's money by discounting at the inflation rate you enter, so you see what the balance is really worth.
Beginning or end of period for contributions?
Beginning-of-period (annuity-due) contributions are invested one period earlier, so they earn slightly more over time.
How is this different from the ROI and Compound Interest calculators?
This projects future growth from ongoing contributions. To measure the return on money you already invested, use the ROI Calculator; for pure compounding across daily/monthly/quarterly/annual periods, use the Compound Interest Calculator.
