ROI Calculator
Calculate the Return on Investment (ROI) and annualized return (CAGR) for any asset.
Why ROI Matters
ROI is the universal metric for profitability. Whether buying a house, investing in stocks, or running a marketing campaign, knowing your ROI helps you make smarter decisions with your capital.
The Return on Investment Formulas
The Simple ROI formula calculates your total nominal return. The Annualized ROI (CAGR) formula determines the geometric mean annual growth rate, allowing you to compare investments of different lengths.
Manual Step: Calculating CAGR
Calculate the Annualized Return (CAGR) for an investment that grew from $1,000 to $1,500 over 3 years.
What's a Good ROI?
| Investment Type | Typical Annual ROI | Risk Level |
|---|---|---|
| S&P 500 Index | 7-10% | Moderate |
| Real Estate | 8-12% | Moderate |
| High-Yield Savings | 4-5% | Low |
| Startup Investment | 25-50%+ | Very High |

The Time Value of Money
The fundamental principle of all finance is the time value of money. A dollar today is worth more than a dollar tomorrow because of its potential earning capacity. This core concept is the engine behind compound interest, mortgages, and retirement planning. When you use financial tools, you are essentially projecting this principle across different time horizons and interest rates to visualize your future wealth.
Navigating Compound Interest
Compound interest is often referred to as the eighth wonder of the world. It is the process where the interest you earn also earns interest. Over long periods, this exponential growth can turn modest savings into substantial wealth. However, it works both ways. Compound interest on debt can quickly overwhelm a budget. This tool helps you quantify that compounding effect so you can make informed decisions about where to deploy your capital.
Risk and Return in Financial Modeling
Every financial calculation inherently involves assumptions about the future. What will the inflation rate be? What is the expected return on the market? These variables introduce risk. A robust financial model doesn't just give you one static number; it allows you to test different scenarios. By adjusting the inputs here, you can stress-test your financial plan against worst-case scenarios.
The Psychology of Financial Planning
Here is what I found: the biggest hurdle in personal finance isn't the math; it's the psychology. Seeing the hard numbers laid out in front of you can be intimidating, but it is also empowering. It removes the ambiguity of 'hoping' you have enough money and replaces it with a concrete target. This tool is designed to give you that clarity, helping you transition from passive saving to active wealth management.
