💵 Lumpsum Investment Calculator
Estimate the future value of a one-time (lumpsum) investment based on your expected annual rate of return and investment time period.
What a lumpsum investment calculator does
A lumpsum investment is a single, one-time deposit made into an investment (unlike a recurring or systematic investment made in installments). This calculator estimates how much that single deposit could grow to by a future date, assuming a steady annual rate of return.
How the future value is calculated
The calculator uses the standard compound growth formula: Future Value = P x (1 + r/n)^(n x t), where P is your initial investment, r is the expected annual return as a decimal, n is how many times per year the return compounds, and t is the number of years invested. More frequent compounding produces slightly higher growth for the same annual rate.
This tool is for general planning and education. It assumes a constant rate of return, which real investments rarely provide — actual returns fluctuate with market conditions and are never guaranteed.
