Econogram is a desktop application for creating and analyzing cash flow diagrams used in engineering economics. It provides a visual interface for working with time value of money calculations, including present value, future value, and annual value conversions.
Econogram helps students and educators visualize and solve engineering economics problems. The software allows you to:
- Create cash flow diagrams with multiple series
- Insert single cash flows, uniform series, gradient series, and geometric series
- Calculate present value (PV), future value (FV), and annual value (AV) of cash flows
- Combine and manipulate cash flow series
- Work with a global interest rate that applies to all calculations
Download the latest standalone executable (.exe) from the Releases page.
No installation required - simply download and run the .exe file.
The application displays cash flows as a bar chart with periods on the x-axis and cash flow amounts on the y-axis. Different series are color-coded for easy identification.
For detailed documentation on all features, see HELP.md.
