Our Approach
We believe a calculator should do more than display a number.
Whenever appropriate, our calculator pages explain the formula, describe how the calculation works, provide instructions for using the calculator, and help users understand what the result means.
Our calculations are based on commonly used mathematical formulas, equations, and publicly available reference information. However, different situations may require different assumptions, formulas, or professional judgment.
Accuracy Matters
We make reasonable efforts to ensure that our calculators and information are accurate and useful. We review formulas, test calculations, and improve our tools when errors or outdated information are identified.
However, calculators are intended for general informational and educational purposes. Results should be independently verified when they are being used for important financial, medical, legal, academic, engineering, or business decisions.
Free and Accessible
Our goal is to keep our calculators easy to access. You do not need to be an expert to use them, and many tools can be used without creating an account.
We also work to make our website useful across desktop computers, tablets, and mobile devices.
