Brian Hughes is correct, thank you. This should not be posted seeing as it is wrong. Look elsewhere for your advice.

Brian Hughes: Thank you for clarifying that the 2 should be a one! I was confused.
and to Bill: the comma key is above the 7, and the brackets are next to the comma but you must press 2nd key first.

Thanks for your page…helped me a lot!

Should be: npv(7, -135000, {50000, 40000, 30000, 50000}, {1, 1, 1, 1}).

The frequency would only be {2, 1, 1} if the payouts were {50000, 50000, 40000, 30000}…..i.e. a “2″ for frequency should only be used if the same amount is used for consecutive periods.

Hey, just wanted to comment on both the internal rate of return and Net Present Value tutorials. Thank you very much for posting these tutorials, but it would have been even more helpful had you posted the argument types that the functions take (e.g. IRR (interest rate, cost, {list of cash flows}, {corresponding frequencies}), followed by the example.
Again, thank you very much. You saved me the trouble of purchasing a financial calculator.
