1. What is Growth Rate Calculation?

The growth rate calculation determines the annualized rate at which an investment grows from its present value to its future value over a specified period. It's essential for evaluating investment performance in TSP (Thrift Savings Plan) and other retirement accounts.

2. How Does the Calculator Work?

The calculator uses the growth rate formula:

\[ \text{Growth Rate} = \left(\frac{\text{Future}}{\text{Present}}\right)^{\frac{1}{\text{Years}}} - 1 \]

Where:

\( Future \) — Future value of the investment (USD)
\( Present \) — Present value of the investment (USD)
\( Years \) — Time period in years

Explanation: The formula calculates the compound annual growth rate (CAGR) that would grow the present value to the future value over the given time period.

3. Importance of Growth Rate

Details: Understanding your TSP growth rate helps evaluate investment performance, compare different funds or strategies, and project future account values for retirement planning.

4. Using the Calculator

Tips: Enter the present and future values in USD, and the time period in years. All values must be positive numbers. The result shows the annualized growth rate as a percentage.

5. Frequently Asked Questions (FAQ)

Q1: What's a good TSP growth rate?
A: Historically, the C Fund (S&P 500) has averaged about 7% annual return after inflation. Growth rates above 5% are generally considered good for long-term retirement investing.

Q2: How often should I check my TSP growth rate?
A: For long-term investors, checking annually is sufficient. Frequent checking may lead to unnecessary concern during market volatility.

Q3: Does this account for contributions?
A: No, this calculates the growth rate of the existing balance. For contribution-adjusted returns, you would need more complex calculations.

Q4: Can I use this for other investments?
A: Yes, this formula works for any investment where you know the starting value, ending value, and time period.

Q5: Why is my growth rate negative?
A: Negative growth rates occur when your ending balance is less than your starting balance, which can happen during market downturns.
