Frequently Asked Questions
Are these business tools really free?
Yes. Every tool is completely free with no limits, no sign-ups, and no watermarks. We're ad-supported so the tools stay free for everyone.
Is my financial data stored or shared?
No. All calculations happen locally in your browser using JavaScript. Nothing you enter is sent to a server, stored in a database, or shared with anyone. Your numbers stay on your device.
Are the calculations accurate?
Yes. Every calculator uses standard, well-documented financial and mathematical formulas. Results match what you would get from a spreadsheet or scientific calculator. For financial calculators, we use the same amortization and compound interest formulas used by banks and lenders.
Can I use these tools on my phone?
Yes. Every tool is fully responsive and works on phones, tablets, and desktops. The interfaces are designed for touch input so you can calculate on the go without downloading an app.
How is this different from the Calculator Tools page?
