1. What is a Lump Sum Retirement Calculator?

Definition: This calculator estimates the future value of a lump sum investment based on compound interest over time.

Purpose: It helps individuals plan for retirement by projecting how a single investment will grow over time.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( FV \) — Future value of the investment ($)
• \( P \) — Initial lump sum amount ($)
• \( r \) — Annual interest rate (in decimal form)
• \( n \) — Number of years invested

Explanation: The formula calculates compound interest, where earnings are reinvested to generate additional earnings.
