GraphCalc Free Online CalculatorsGraphCalc History

GraphCalc was originally created by two Bucknell graduates in 1999 as one of the first Windows graphing calculator software packages. This rich 3D graphing program easily replaced the expensive handheld, monochrome scientific calculators of its day.

The GraphCalc Windows 3D graphing calculator software was packed with features and allowed users to compute basic math functions, perform statistical analysis, calculate advanced calculus and derivatives, and of course graph just about anything. The interface was easy to use and helped students and professionals focus on math instead of how to use software.

This revolutionary idea was released to the public for free in January 1999, so anyone could use it to pursue their education or career.


GraphCalc Today

Since that time, GraphCalc has evolved from offering a single 3D graphing calculator into one of the world’s leading resources for free online calculators and conversion tools. GraphCalc offers over 450 different calculators for math, finance, and fitness. Here are some of the main types of calculators that we offer:
