We believe everyone deserves access to fast, accurate, and easy-to-use calculators. Whether you're planning a mortgage, tracking your fitness goals, or solving a math problem, we've got you covered.
World Calculator is built by a small team of software engineers and mathematicians who share a simple passion: making calculations faster and more accessible for everyone.
We've spent countless hours perfecting formulas, optimizing performance, and designing interfaces that just work. No sign-ups required, no data collection on your calculations. Just pure, reliable tools.
Every calculator on World Calculator goes through a rigorous development process to ensure accuracy, reliability, and ease of use. We don't just implement formulas—we validate them against multiple authoritative sources and test them extensively across different scenarios.
Our commitment to precision means that whether you're calculating a mortgage payment, tracking your BMI, or converting units, you can trust the results. We cross-reference our formulas with financial institutions, medical guidelines, and mathematical standards to ensure they meet professional-grade accuracy requirements.
We analyze competitor implementations, consult authoritative sources, and validate formulas against industry standards before writing a single line of code.
Our engineers use TypeScript with strict type safety and comprehensive validation to ensure every input is properly handled and every edge case is considered.
Each calculator undergoes rigorous testing including unit tests, edge case validation, and real-world scenario verification to ensure accuracy.
We monitor user feedback, track performance metrics, and regularly update our calculators to incorporate the latest formulas and best practices.
Our team combines expertise in software engineering, mathematics, financial analysis, and user experience design. With backgrounds ranging from fintech development to academic research, we bring a diverse set of skills to ensure every calculator is both technically sound and user-friendly. We're passionate about democratizing access to powerful calculation tools that traditionally required expensive software or specialized knowledge. Based across Europe, we work remotely but stay united by our mission to make accurate calculations accessible to everyone, everywhere.
All calculators are completely free to use, forever. No premium tiers or hidden features.
Your calculations stay in your browser. We never see, store, or sell your data.
Built by mathematicians who obsess over accuracy. Every formula is verified and tested.
Available in 6 languages with locale-specific formatting. Use it on any device.
