Like any budget, it is divided into two columns: expenses and income, which are then divided into several categories.
Expenses
Expenses are calculated first, with the revenues being adjusted on the other side according to their amount.
Among the direct costs:
- the sum of the salaries of internal human resources in proportion to the number of (planned) hours dedicated to the project,
Calculation: gross salary + payroll and employer charges x hours worked x number of months or weeks (depending on whether it is a monthly or annual budget).
This is called a "full-time equivalent".
- Operating expenses (procurement, subcontracting),
- the cost of external labor multiplied by the duration of the intervention,
- the cost of purchasing or renting equipment specific to the project (e.g., supplies, paper, renting a training room),
- costs related to project communication (graphics, printing, costs related to dissemination, etc.),
- travel, meeting costs, etc.
Indirect costs
(for the cost of resources allocated to several projects, not exclusively to the project in question, shared by means of distribution keys) :
Here is an example:
To allocate the cost of rent, take the average occupancy time of the premises according to the size of each project, and distribute it as a percentage. If project 1 occupies the space, 20% of the time, project 2, 30% of the time and project 3, 50% of the time. Then 20% of the charges for rent, electricity, water, etc. should be allocated to project 1 and so on.
- Miscellaneous charges: water, electricity, telephone bills, rent and rental charges, insurance, maintenance of premises and equipment,
- management costs: salaries for services that are transversal to the company or outsourced (legal department, accounting department, security),
- taxes,
- financial expenses: bank loans, interest payable, premiums,
- communication costs,
Revenue
- product sales,
- service fees,
- subsidies,
- partnerships,
- self-financing,
Cost control
“NB: a popular calculation method used in project management is Earned Value Management or the S-curve. It is used to measure the progress of a project and anticipate the next steps by comparing forecasts with actions that are being carried out and their associated costs”
