Financial management: Hehai Co., Ltd. plans to buy a piece of equipment at a price of 100000 yuan, which can increase the net income for the enterprise every year.

Annual cash flow =6600+ 100000/5=26600.

(1) payback period of static investment of this project: 100000/26600=3.76 years.

(2) Net present value of the project =26600*(P/A, 10%, 5)-100000 = 26600 * 3.79-100000 = 814.

The net present value is positive, so the project is feasible.

(3) The IRR of the project R

26600*(P/A,R,5)- 100000=0

R= 10. 16%

The internal rate of return of the evaluation project 10. 16% is greater than the expected rate of return 10%, which is feasible!
