Calculate Project ROI
Calculating ROI for a project/task should consider both tangible and intangible benefits.
Example: Benefits like increasing employee morale (intangible) can be converted to be tangible as follows:
Increase employee morale can increase employee retention, which can save new employee recruiting and training costs. Based on the employee turnover last year, HR dept can provide tangible figures like “Reduce Employee turnover by 5% and save $5000 in new recruiting costs.
Understand cash flow
Example: Project to create ecommerce website to sell your products online may provide the following cash flow:
Current Year: Expected to spend $10,000 to develop the website.(One year time-frame – not a capital project)
Year-1: After website is deployed, it is expected to generate $4,000 in the first year.
Year-2: Expected to generate $5,000 in the second year.
Year-3: Expected to generate $5,000 in the third year
Year-4: Expected to generate $2,000 in the fourth year.
Year-5: Expected to generate $2,000 in the fifth year
Understand your discount rate
Discount rate is the minimum expected rate of investment, based on analyzing other alternate investment options for the capital.
Example: If a bank would give you a 10% interest on the investment if deposited then projects should return more than 10% to be a better investment option.
Calculate ROI factors
Based on your organizational standards (environment factors, accounting, finance, IT governance and other standards) identify the ROI factors (NPV, IRR, Payback period are typically used to calculate ROI).
In the example above, you may have considered the website as a better return on investment because of the following:
Amount Spend: $10,000
Amount Earned: $4,000+$5,000+$5,000+$2,000+$2,000 = $18,000.00
Net Diff = $18,000 - $10,000 = $8,000 (Profit over 5 year period).
But, you cannot assume the above, without considering the discounted cash flow analysis.
What is discount cash flow?
Discounted cash flow is a cash flow analysis based on time value for money (considering money is relative – A Dollar is worth more today than it is worth in the future).
Net Present Value (NPV) :
Net present value is calculated by discounting all future income amounts based on the discount rate and adding the discounted income stream.
Net Present Value calculation = (Cash flow amount) / ((1 + Discount Rate) to the power of number of years)
For example in the above example, if the discount rate is 10%, the cash flow should be as follows:
Scenario-1: Assuming the payment $10,000 as made at the beginning of the year
Internal rate of return is the discount rate that makes the net present value equal 0.
In the above example, IRR is 27.3% (appox). It is the discount rate that makes the NPV zero (close to zero).
The payback period is how long it will take to recover amount invested in a project (it is recommended to use discounted flows to calculate payback period )
In the above example, in scenario -1 the payback period is calculated by adding the discounted amounts every year until you meet or exceed the amount spend ie $10,000 in the example ) :
Analyze ROI factors
Based on the calculated ROI factors, analyze each project and compare their return on investment and use project portfolio management standards to approve projects. Please see the following multimedia article about Portfolio Management from Technology Governance Solutions.
