1. What is a Lump Sum Growth Calculator?

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

Purpose: It helps investors project how their one-time investments might grow over time with compound interest.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( FV \) — Future value of investment ($)
• \( P \) — Principal amount ($)
• \( r \) — Annual interest rate (as decimal)
• \( n \) — Number of years invested

Explanation: The formula calculates compound growth by applying the annual rate to the increasing balance each year.

3. Importance of Lump Sum Growth Calculation

Details: Understanding potential growth helps with retirement planning, investment decisions, and financial goal setting.

4. Using the Calculator

Tips: Enter the principal amount, annual rate (5% = 0.05), and number of years. All values must be positive.

A: No, this calculates growth of a single lump sum. For regular contributions, use a different calculator.

Q4: Does this account for inflation?
