How This Calculator Works

This calculator projects the future value of an investment combining an initial lump sum and ongoing monthly contributions at a fixed expected annual return. The area chart shows year-by-year growth.

Formula

FV = P(1+r)^t + PMT × [((1+r)^t − 1) / r]

Example

$50,000 plus $500/mo at 8% for 25 years grows to about $838,000 — a gain of roughly $638,000.

Practical Use Cases

  • Retirement planning
  • Goal-based investing
  • Comparing return assumptions
