Our Mission
At 101 Calculators, we believe that complex decisions shouldn't require complex software. Our mission is to provide free, high-precision, and easy-to-use calculators for everyone—from finance professionals and business owners to fitness enthusiasts and students. We bridge the gap between complicated spreadsheets and simple, accessible web tools.
Who We Are
We are a dedicated team of financial analysts, software engineers, and domain experts passionate about building tools that solve real-world problems. Whether you're planning your retirement with our FIRE calculators, optimizing your Amazon FBA business, or tracking your sleep cycles, our tools are built with researched formulas and rigorous testing to ensure accuracy you can trust.
Why Choose Us?
- Precision: We don't just use generic formulas. We research the nuances of each field (like tax laws or biological metrics) to provide the most accurate results possible.
- Privacy-First: Most of our calculators run directly in your browser. We don't store your personal financial data.
- Free Forever: We believe essential planning tools should be accessible to all, not locked behind subscriptions.
