Fees compound too
A small annual fee can create a meaningful long-term difference because it reduces the capital left to compound.
Nominal vs real value
Inflation-adjusted value expresses future money in approximately today’s purchasing power.
How the Investment Calculator works
Calculations run entirely in your browser. We apply the formulas shown above to a month-by-month schedule, hold your entered rate constant, and treat every result as an estimate—not a forecast or bank quote.
FREQUENTLY ASKED QUESTIONS
Clear answers. Better inputs.
What return should I enter?+
Test a reasonable range instead of relying on one precise number. Historical averages do not guarantee future results.
Does this predict the market?+
No. It applies a constant mathematical return and cannot represent real volatility.
Are taxes included?+
No. Account type and individual tax treatment can materially change after-tax results.
