Investment Growth Calculator

About Investment Growth Calculator

Project investment growth over time. This calculator provides instant results with step-by-step explanations to help you understand the calculation process.

How to use this calculator

1. Enter the starting investment amount.
2. Enter the growth rate and choose the time period.
3. Enter how many periods you want to project.
4. Calculate the future value using the formula.

The formula explained

• \(\text{Future Value}\) = the projected value of the investment after growth
• \(\text{Present Value}\) = the starting amount invested
• \(r\) = the growth rate per period as a decimal
• \(n\) = the number of periods

Step by step method

1. Start with the initial amount you invest, called the present value.
2. Convert the growth rate to a decimal if needed.
3. Apply the rate for each period by raising \(1 + r\) to the power of \(n\).
4. Multiply the result by the starting amount to get the projected value.

Worked example

Suppose you invest 2,000 dollars at a 5 percent annual growth rate for 3 years.

1. Write the formula as \(\text{Future Value} = 2000 \cdot (1 + 0.05)^3\).
2. Calculate the growth factor: \(1.05^3 = 1.157625\).
3. Multiply: \(2000 \cdot 1.157625 = 2315.25\).

Tips and common mistakes

• Make sure the growth rate is entered as a decimal, not a whole number.
• Check whether the calculator uses annual, monthly, or another period, since the time unit must match the rate.
• If you are comparing investments, use the same starting amount and time period for each one.
• Remember that this tool projects growth using a formula, so real market results can differ.
