Understanding your calculation

Method, example and limitations

How the calculation works

An investment projection combines an opening balance, deposits and assumed growth over time. Keep contribution frequency, growth frequency and start/end timing consistent.

Example to check

With no deposits or fees, $1,000 at an assumed 5% annual return becomes $1,050 after one year.

Before using the result

Constant growth is an illustration, not a forecast. Market losses, fees, tax, inflation and changes in deposits affect actual outcomes.
