HP12c

The HP12c Chrome extension is a fully featured financial calculator replicating the classic HP-12C's capabilities. It supports all standard HP12c functions such as time value of money (TVM), internal rate of return (IRR), net present value (NPV), bond pricing and yields, calendar calculations, and more.

Designed for professionals in real estate, mortgage brokering, banking, leasing, and trading, this extension includes programming features with conditional branching and looping, multiple program storage, as well as advanced financial and statistical computations. Its intuitive interface harnesses reverse polish notation (RPN) with a 4-register stack and storage for up to 99 program lines, making it a powerful tool for complex financial analyses.
