Annualized Growth Formula
The core of the Annualized Growth (or Compound Interest) calculation is the Future Value (FV) formula. Since this is a big calculator, we derive this formula to solve for any of the four variables: FV, PV, Rate (i), or Periods (n).
FV = PV * (1 + i)n

Understanding the variables is essential for correct usage:
- Present Value (PV): The initial amount of the investment or loan at the start.
- Future Value (FV): The value of the investment at a specific date in the future, including compounding interest.
- Annual Rate of Return (i): The interest rate earned or paid per compounding period, expressed as a decimal (e.g., 5% should be entered as 5 in the calculator, which converts to 0.05).
- Number of Periods (n): The number of years or compounding periods over which the investment grows.

What is Annualized Growth?
Annualized Growth, also known as the Compound Annual Growth Rate (CAGR) when looking retrospectively, is the average rate at which an investment grows over a specific period, assuming the profits are reinvested. It is a fundamental metric in finance, providing a smoothed, annual rate of return figure that can be used to compare investments across different time horizons.
Unlike simple interest, which is calculated only on the principal amount, compound interest is calculated on the principal amount and also on the accumulated interest from previous periods. This ‘interest on interest’ effect is what drives long-term wealth creation, making the time horizon ($n$) a critical factor in the formula.
Using a tool like this big calculator allows users to model different scenarios—whether planning for retirement (solving for FV) or determining what rate of return is needed to hit a goal (solving for i).
How to Calculate Annualized Growth (Example)
Let’s use an example to calculate the Future Value (FV) of an investment:
- Define Variables: Start with an initial investment (PV) of $5,000, an annual rate (i) of 7%, and a period ($n$) of 10 years.
- Convert Rate: Convert the percentage to a decimal: $7\% = 0.07$.
- Apply Formula: Substitute the values into the FV formula: $$FV = \$5,000 \times (1 + 0.07)^{10}$$
- Solve Exponent: Calculate $(1.07)^{10} \approx 1.96715$.
- Final Calculation: $$FV = \$5,000 \times 1.96715 = \$9,835.75$$
Therefore, your investment of $5,000 will grow to $9,835.75 after 10 years at a 7% annual rate of return.
Frequently Asked Questions (FAQ)
Is the Annualized Rate of Return the same as CAGR?
Yes, conceptually they are the same. CAGR (Compound Annual Growth Rate) is typically used to describe the historical rate of return for a past investment, while the ‘Annual Rate of Return’ in this formula can be used to project future growth based on an assumed rate.
Why did I get an error when solving for the Rate ($i$)?
If you enter a Future Value (FV) that is lower than your Present Value (PV), and your Number of Periods ($n$) is positive, the calculator will return an error because it implies a negative rate of return, which can lead to complex mathematical issues (like taking the root of a negative number if the exponent is complex). The calculator handles non-physical results.
What does it mean to solve for $n$?
Solving for $n$ (Number of Periods) allows you to determine how long it will take for your initial investment (PV) to reach a specific financial goal (FV) at a given rate (i). This is useful for long-term financial planning.
Does this calculator account for deposits or withdrawals?
No. This calculator is for a single lump-sum investment (PV) that grows over time. For continuous contributions or withdrawals, you would need an Annuity Calculator or a more complex financial model.
