The **steamdb/calculator** helps investors determine the true annual rate of return on an investment over a multi-year period, essential for comparing investment performance across different time horizons.

Annualized Return Formula (steamdb/calculator Formula)
When solving for the **Annualized Return Rate (A)**:
$$\text{A} = \left(\frac{\text{R}}{\text{I}}\right)^{\left(\frac{1}{\text{T}}\right)} – 1$$Where:
- A = Annualized Return Rate (as a decimal)
- R = Final Revenue
- I = Initial Investment
- T = Time Period (in years)

Variables Explanation
- Initial Investment (I): The original principal amount of money invested or cost of the asset.
- Final Revenue (R): The total value of the investment or revenue received at the end of the time period.
- Time Period (T): The total duration (in years) the investment was held or the asset was owned.
- Annualized Return Rate (A): The constant rate at which the investment would have grown each year on a compounding basis.

What is Annualized Return? (steamdb/calculator)
Annualized Return is a measure of the geometric average amount of money earned on an investment over a year. It’s often used to compare the performance of investments that have been held for different lengths of time. Unlike a simple return, the annualized return accounts for compounding effects, providing a more accurate picture of the investment’s actual growth rate.
For investors, particularly those dealing with fluctuating digital asset markets like **steamdb** items, calculating the annualized return is crucial for rational decision-making. It helps in assessing whether the risk taken was justified by the compounding gains achieved over the holding period.
How to Calculate Annualized Return (Example)
- Determine the Gain Ratio: Divide the Final Revenue (R) by the Initial Investment (I). (Example: $1,500 / $1,000 = 1.5).
- Calculate the Time Exponent: Find the reciprocal of the Time Period (T). (Example: 1 / 3 years = 0.3333).
- Apply the Exponent: Raise the Gain Ratio (1.5) to the Time Exponent (0.3333). (Example: $1.5^{0.3333} \approx 1.1447$).
- Subtract One: Subtract 1 from the result to get the Annualized Return as a decimal. (Example: $1.1447 – 1 = 0.1447$).
- Convert to Percentage: Multiply by 100 to express the result as a percentage (14.47%).
Frequently Asked Questions (FAQ)
Q: Why use Annualized Return instead of Simple Return?
A: Annualized return is superior because it smooths out the return over the entire investment period and accounts for the compounding effect, making it the only fair metric for comparing assets held for different durations.
Q: Can the Annualized Return be negative?
A: Yes. If the Final Revenue (R) is less than the Initial Investment (I) (a net loss), the resulting annualized return will be a negative percentage.
Q: How do I handle investments less than a year?
A: The time period (T) should be entered as a fraction of a year (e.g., 6 months = 0.5 years). The formula is still mathematically valid for periods less than 1.
Q: What is the main limitation of this calculator?
A: It assumes a single lump sum investment at the start and does not account for continuous contributions or withdrawals (Dollar-Cost Averaging), which would require a more complex calculation like the Modified Dietz Method.
