NPV for HP 15


A short program for the HP15c. It can be used for IRR using the solve function.

We store the cash flows in registers 0 to 10.
We store the number of cashflows in register 11 (.1)
we enter the discount rate (r) in the x register before running it.

Just enter the interval you think the return rate is in x and y registers, and then press:

f SOLVE 0

It takes a little bit long - with the old HP15c - not so with the Ipod version or the new, upcoming HP15c+
