The Investment Calculator is an essential tool for anyone looking to understand the potential growth of their investments over time. Whether you’re saving for retirement, a large purchase, or just want to evaluate your financial portfolio, this calculator helps you determine how much your initial investment could grow, factoring in return rates, compound interest, and additional contributions.
What is an Investment Calculator?
An Investment Calculator is a tool that helps you estimate the future value of your investment. It takes into account the initial amount of money invested, the number of years it will be invested, the expected return rate (interest), and any additional contributions you make over time. The results show you how your investment will grow with compound interest.
This calculator uses a simplified version of the compound interest formula to calculate how much your money will grow.
How to Use the Investment Calculator
Using the Investment Calculator is easy and intuitive. Here’s how you can use it:
- Enter the Starting Amount: This is the amount of money you plan to invest initially. It can be any amount, and the calculator will calculate the growth based on this value.
- Enter the Number of Years: This field asks for the number of years you want your investment to grow. The longer you invest, the more you’ll benefit from compound interest.
- Enter the Expected Return Rate: The return rate is the annual percentage return you expect on your investment. This value is usually based on past performance or an estimate of future performance.
- Choose Compound Frequency: This option allows you to specify whether your investment compounds annually (once a year), which is the most common method.
- Additional Contribution: If you plan on making additional contributions (such as monthly or yearly deposits), enter this amount in the relevant field.
- Click “Calculate”: After entering all the information, click the “Calculate” button to view the future value of your investment.
Formula Used for Investment Calculation
The basic formula used for calculating the future value of your investment is based on compound interest principles:
Future Value = P * (1 + r)^t + (PMT * ((1 + r)^t – 1) / r)
Where:
- P = Starting amount (principal)
- r = Return rate (annual interest rate)
- t = Time in years
- PMT = Additional contribution (if any)
In this case, the calculator applies the formula each year and adds any contributions you specify. The formula also assumes annual compounding, meaning interest is calculated at the end of each year.
Example Calculation
Let’s go through an example to better understand how the Investment Calculator works.
Example Inputs:
- Starting Amount: $10,000
- Years: 5
- Return Rate: 8%
- Compound Frequency: Annually (checked)
- Additional Contribution: $500 per year
Step-by-Step Calculation:
- Year 1:
Future Value = $10,000 * (1 + 0.08) + $500 = $10,800 + $500 = $11,300 - Year 2:
Future Value = $11,300 * (1 + 0.08) + $500 = $12,204 + $500 = $12,704 - Year 3:
Future Value = $12,704 * (1 + 0.08) + $500 = $13,713 + $500 = $14,213 - Year 4:
Future Value = $14,213 * (1 + 0.08) + $500 = $15,336 + $500 = $15,836 - Year 5:
Future Value = $15,836 * (1 + 0.08) + $500 = $17,133 + $500 = $17,633
After 5 years, your investment would grow to $17,633, including your initial investment and the additional contributions.

Compound Interest Explained
Compound interest is the interest on a loan or investment that is calculated based on both the initial principal and the accumulated interest from previous periods. The more frequently interest is compounded, the greater the amount of growth.
In this calculator, compounding annually means the interest is added to the principal once per year. If you check other options like monthly or quarterly, the growth will be faster.
