Investment Calculator
Project investment growth with compound interest and charts
About this tool
Model the future value of an investment with compound interest. Enter your initial lump sum, monthly contribution, expected annual return, investment period, and compounding frequency (daily, monthly, or annually). Get the final value, total amount contributed, and total gains at a glance. A year-by-year growth table and an SVG line chart visualise the journey, and an optional inflation adjustment shows the real purchasing-power equivalent of your returns.
