    You haven't gone very wrong, you just haven't been clear about what you've calculated.

    1.94 years is not the payback period, what you worked out is that the payment period is 1 year, 9.4 months.

    Which is also the same as 1.78 years (because of the 12 months to a year thing).

    Just be sure to write it as one way or the other, because 1.94 years is wrong.
