- ARR
- NPV
- IRR
4 methods of investment appraisal
- Payback method
- ARR
- NPV
- IRR
Disadvantages of payback method
- arbitrary decision
- doesn’t take time value of money into account
- ignores future CF
Formula for ARR
Average return (profit)/Initial investment
Disadvantages of ARR
- arbitrary decision
- uses profits rather than CF
Formula for IRR
IRR = r(a) + {NPV(a)*[r(b)-r(a)]/[NPV(a)-NPV(b)]}
Advantages of NPV
- takes into account time value of money
- absolute measure of return
- based on CF not profits
- considers whole life of the project
Non-financial factors affecting NPV
- compliance with legislation
- impact on key stakeholders
- impact on reputation
- sustainability
Annuity discount factor formula
1/r*{1-[1/(1+r)^n]}
Perpetuity discount factor formula
1/r
Growing perpetuity discount factor formula
1/(r-g)
What CF should be included in calculation of NPV?
Future incremental cash flows which arise as a result of decision being taken.
Which costs should be ignored when calculating NPV?
- sunk costs (e.g. historical market research)
- commited costs (e.g. salaries, unless paid extra to do the project)
- non-cash items (e.g. depreciation)
- book values (e.g. cost of machine bought)
- allocated costs (e.g overhead allocation)
What is an opportunity cost?
Change in CF if a unit of resource is used in a project rather than on the next best alternative.
How to calculate deprival value?
Deprival value is lower of: - replacement cost - recoverable amount (which is higher of: => value in use => net realisable value
