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. ;-) Hey, just wanted to comment on both the internal rate of return and Net Present Value tutorials.

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.
