1. What is a Lump Sum Investment Calculator?

Definition: This calculator estimates the future value of a single lump sum investment based on principal amount, interest rate, and time period.

Where:

• \( FV \) — Future value of investment ($)
• \( P \) — Principal investment amount ($)
• \( r \) — Annual interest rate (decimal)
