How to do a Cost Benefit Analysis: Tips for Busy Managers

What is a Cost Benefit Analysis

It is a tool used to more objectively assess:

• the value of a solution or action
• the comparison between alternative courses of action or solutions

For our purposes, it does not include detailed financial analysis


When to conduct a Cost Benefit Analysis

• To determine feasibility of a solution or course of action
• To compare alternative courses of action or solutions
• When you want to justify a course of action
• When you are looking for additional resources for something


How to do a Cost Benefit Analysis

1. Determine the Costs
2. Calculate the Benefits
3. Compare Alternatives
4. Report and Plan Action


1. Determine the Costs

• First you should check to see if any analysis has already been done on your project or idea. Maybe there has already been some detailed costing work done. If not, you will need to collect the cost numbers.
• List out costs of your solution or course of action e.g.:

– Initial or capital costs
– Ongoing costs – what are the costs in the coming months or years?
– Labor costs – how much time will your idea take from people?
– Contractor costs – Are there external labor costs?
– Supply or input costs
– Non-monetary costs – what is the impact on safety, morale, reputation and other less tangible things. You may not be able to assign a number to these things, but you should at least list them for consideration.


2. Calculate Benefits

The next step in the Cost Benefit Analysis is to estimate the benefits on all the same dimensions as you did for costs:

• Dollar value of benefits e.g.:

– Time (labor) saved
– Supply (input) savings
– Energy savings

• Non-monetary benefits e.g.:

– Safety, environmental
– Reputation
– Morale, turnover
– Quality

You need to think aboutr the immediate, yearly, and ongoing benefits in your Cost Benefit Analysis.


3. Compare Alternatives

You now need to compare the costs and benefits from each of your alternatives. If there is one alternative, you are still comparing your option with the status quo.

• Subtract costs from benefits for each alternative
• First compare against doing nothing
• Compare each alternative with each other
• Take non-monetary into consideration


4. Report and Plan Action for your Cost Benefit Analysis

• Make a recommendation based on your Cost Benefit Analysis
• Put together a brief plan of action for your recommendation.
• Don’t forget about other influencing conditions. Sometimes, you may have a compelling argument that still needs to be deferred for other reasons, such as:

– Cash flow
– Availability of resources
– Competing priorities
