FAQ

What is the main use case for this calculator?

It is best for testing how starting capital, recurring contributions, time, and return assumptions combine to shape long-term investment growth.

Why show real and nominal results?

Nominal growth looks good on its own, but real results show what that portfolio could actually buy after inflation.

Which assumptions matter most?

Time invested, contribution rate, and average return have the biggest compounding effect in most scenarios.
