Monthly Investment Calculator
Project long-term savings from recurring monthly contributions. Adjust the assumptions and explore the result. Nothing is sent to our servers.
How to interpret this: Currency selection changes only the symbol and formatting, not any exchange rate. All growth calculations use a fixed-rate, end-of-month-contribution model; results are examples, not offers or forecasts.
Understanding recurring investments
This calculator estimates the future value of equal monthly investments using a constant illustrative annual rate, compounded monthly. It assumes each contribution occurs at the end of the month.
The reported growth is the estimated future value minus the amount you paid in. Negative assumed returns are allowed to illustrate downside scenarios.
Compare several return assumptions rather than treating one number as an expected outcome. Real investments can fluctuate sharply and may lose value.
Important limitation: Figures exclude investment fees, tax, inflation, bid-ask spreads, transaction costs, and sequence-of-returns risk.
