The HP 12C-120 Financial Calculator

The HP 12C-120 is a financial calculator built for professionals in banking, real estate and accounting. It delivers over 120 built-in functions covering TVM, NPV, IRR, bond calculations and amortisation schedules. Reverse Polish Notation entry reduces keystrokes for repetitive workflows. The unit ships new with a protective case, cleaning cloth and pre-installed batteries.

Sustained desktop use with RPN efficiency

The calculator handles extended sessions of cash-flow modelling and depreciation work without slowing down. Its programmable memory stores up to 20 cash flows and custom keystroke sequences for recurring tasks. Battery power avoids mains dependency during long days at the desk or on site. The LCD remains legible under office lighting for continuous reading.

Compact plastic build with travel case

The black plastic chassis measures 2.4 in by 3.96 in by 1.3 in and weighs 0.272 kilograms, fitting easily on a crowded workspace. A snap-on hard case protects the keyboard and display during transport. The included cleaning cloth keeps the LCD clear of fingerprints. No cables or chargers are required, so the kit stays minimal in a briefcase.

Questions about this item

Does the HP 12C-120 generate noticeable heat or fan noise when left running all day?

The calculator has no fan and uses a low-power LCD, so it produces no audible noise and stays cool during extended use.

What must I already own for the HP 12C-120 to work out of the box?

Nothing extra is required; the unit ships with pre-installed non-standard batteries, a protective case and a cleaning cloth.

Can I run the same RPN keystroke programs I wrote for an HP 12C made decades ago on this HP 12C-120?

Yes, the 12C-120 uses the same RPN entry system and programmable memory, so legacy keystroke sequences are compatible.
