Compound Interest Simulator
Compound Interest Simulator
Visualise how your money grows over time with
monthly contributions and
compound interest.
How much you start with today (lump sum).
Amount you plan to add every month.
How long you’ll keep investing. Simulator assumes monthly compounding.
Average yearly growth rate (e.g. 8–12% for growth investments, lower for safer options).
Please enter sensible values: time must be positive and at least one of
initial amount or monthly contribution should be greater than zero.
💡 Use this to compare “start early & small” vs
“start later & big” by changing the years and monthly amount.
