For a project costing RM1,000,000 with inflows of RM300,000, RM400,000 and RM500,000 over three years, the IRR is about 8.9%. If the cost of capital is 10%, the IRR rule says:
The IRR is the discount rate that sets NPV to zero; here about 8.9%. The rule accepts a conventional project only if its IRR exceeds the cost of capital, and 8.9% < 10%, so reject, which agrees with the negative NPV at 10% (−RM21,037). A positive IRR only shows the project returns more than zero. Total inflows exceeding the outlay ignore discounting. Comparing a rate with a number of years is meaningless.

Accepting any project with a positive IRR. The hurdle is the cost of capital, not zero.
