AGEC/FNR 406 LECTURE 10 Rice drying on the Philippine National Highway
Benefit-Cost Measures Lecture Goals: 1.Present three tools of benefit-cost analysis 2. Discuss advantages and disadvantages of BCA Don’t neglect to review the BCA packet!
Three BCA tools: 1. Net Present Value (NPV) 2. Benefit-Cost Ratio (BCR) 3. Net Present Value (NPV)
Net Present Value (NPV) The net present value of benefits is the present value of those net benefits. Net benefit is simply the sum of benefits minus the sum of costs. NPV is the current value of all net benefits associated with a project The net benefits are converted to present value by discounting.
Key Point If the project has a NPV > 0, then it is worth considering on its economic merits. If the project has a NPV < 0, then it fails to return benefits greater than the value of the resources used.
Internal Rate of Return (IRR) The IRR is the maximum interest rate that could be paid for the project resources that would leave enough money to cover investment costs and still allow society to break even. The IRR is the discount rate at which the PVof benefits equals the present value of costs.
IRR Formula Solve for the IRR by finding i that solves: PV(Benefits) = PV(Costs) Use algebra or a spreadsheet
Key Point The IRR must exceed the chosen discount rate for the project to be accepted.
