Wish to create a project budget online? The project budget includes the total expenditure expected in the project. A budget includes the financial obligations for your business in conducting a project. In this case, you will define the activities first. Then, define the cost of each activity, including the items to be used. Each item has a purchase and a selling price. Hence, you will calculate the total expenses in the project, which becomes the total project budget. The next step is to define the financial schedule, whereby the funds for each milestone are defined, including the expected date for the funds’ release and the responsible parties. In a business, the milestone budget is allocated per department, whereby the project manager will involve the departmental managers in determining the budget for the activities to be done under their department.
