Overview
A finance classroom, a brokerage desk or a real estate office is where this HP 12C belongs. It is a desktop financial calculator with RPN entry and an LCD, and the title lists time value of money, net present value, internal rate of return, amortization and bond functions.
The long function list and programmable keys suit repeated finance calculations, and two extras ship with it. RPN entry takes learning for users new to it, and the listing does not say whether the battery is supplied.
Who it's for
Loan, bond and cash flow work are the intended uses. Beginners who are not ready to learn RPN, or users who need a larger display, should look at another model.
Pros and cons
- Long list of financial functions
- RPN entry for fast chained work
- Case and cloth included
- RPN entry has a learning curve
- Battery inclusion not stated
- No graphing capability listed
Performance notes
RPN entry enters values first and the operation after, which shortens chained cash flow steps once learned. Programmable keys store repeated sequences, and an LCD shows results on a small readout.
