Why We Built These Tools
Most financial calculators online are designed to collect your email or sell you a product. We built these tools because we use them ourselves. Every calculator on this page is free, private, and runs entirely in your browser. Your financial data never touches our servers.
Each calculator is maintained by our editorial team and validated against standard financial formulas used by banks and investment firms. We update the underlying assumptions and defaults as market conditions change.
How to Get the Most from These Calculators

Use the ROI Calculator to compare past investments or evaluate potential opportunities. The annualized return makes it easy to compare investments with different holding periods.

Run your portfolio through the Dividend Yield Calculator to understand your passive income stream and how dividend growth compounds your income over time.
The Inflation Calculator is essential for any long-term financial plan. It shows why keeping large sums in low-yield accounts is one of the most costly financial decisions you can make.
