You can calculate the EV of a project by multiplying the percent complete by the total project budget. For example, let's say you're 60% done, and your project budget is $100,000, then your earned value is $60,000.
They are as follows:
- EAC = AC + Bottom-up ETC. This formula is used when the original estimation is fundamentally flawed.
- EAC =BAC/Cumulative CPI. This formula is used when the original estimation is met without any deviation.
- EAC = AC + (BAC - EV)
- EAC = AC + [BAC - EV / (Cumulative CPI x Cumulative SPI)]
Example of Present ValueUsing the present value formula, the calculation is $2,200 (FV) / (1 +. 03)^1. PV = $2,135.92, or the minimum amount that you would need to be paid today to have $2,200 one year from now.
The actual cost for projects equals direct costs + indirect costs + fixed costs + variable costs + sunken costs. Alternatively, you can use PMI's simplified formula, which is: actual cost= direct cost + indirect cost.
EV is a measure of work performed or the budget authorized for that work. In other words, it's the budget authorized for completed work. The value of EV cannot be greater than the authorized PV budget for a component. You require only the percentage of work completed.
Planned Value (PV) is the budgeted cost for the work scheduled to be done. This is the portion of the project budget planned to be spent at any given point in time. This is also known as the budgeted cost of work scheduled (BCWS). Actual Costs (AC) is simply the money spent for the work accomplished.
The cost performance index (CPI) is a measure of the financial effectiveness and efficiency of a project. It represents the amount of completed work for every unit of cost spent. As a ratio it is calculated by dividing the budgeted cost of work completed, or earned value, by the actual cost of the work performed.
The Cost Performance Index (CPI) is defined as the ratio of Earned Value to Actual Cost, while the Schedule Performance Index (SPI) is defined as the ratio of cumulative Earned Value to cumulative Planned Value (PMI, 2000).
In Practice. Earned Value is an objective and reliable productivity measure. If the Earned Value is less than the Planned Value, you are behind schedule, and if the Earned Value is greater than the Planned Value, you are ahead of schedule.
The three main and critical EVM metrics are planned value, actual cost and earned value.
Lack of management commitment. Earned Value initiatives take time to set up and can involve a complete rethink of how success is measured. It's not just a financial tool; it impacts a company's total revenue stream and measures the company's ability to manage cost, schedule and technical performance.
Earned value is a project management technique for estimating how a project is doing in terms of its budget and schedule. The purpose of earned value is to obtain an estimate for the resources that will have been used at completion.
SPI = EV ÷ PV. If the SPI is less than one, it indicates that the project is potentially behind schedule to-date whereas an SPI greater than one, indicates the project is running ahead of schedule. What Is A Good Spi? / Difference between Cost Performance Index (CPI) and Schedule ↗
8-80 rule states that work packages must be between eight hours and eighty hours chunks of work. If the projects are big, then work packages can be around 80 hour chunks of work. For small projects the work packages can be around 8 hours, or it could be anything between 8 hours and 80 hours.
The Project Management Institute (PMI) Project Management Book of Knowledge (PMBOK) defines the Work Breakdown Structure as a “deliverable oriented hierarchical decomposition of the work to be executed by the project team.” There are two types of WBS: 1) Deliverable-Based and 2) Phase-Based.
The earned value metric is actually the planned value of the work that has been accomplished, but it is often referred to as the budgeted cost for work performed (BCWP). The baseline plan that performance is measured against is an aggregation of the timephased value of the work planned to be performed.
AgileEVM requires a minimal set of input parameters: the actual cost of a project, an estimated product backlog, a release plan that provides information on the number of iterations in the release and the assumed velocity. All estimates can be in hours, story-points, team days or any other consistent estimate of size.

Several measurement methods are used to measure discrete effort, such as the Fixed Formula, the Milestones with Weighted Values, the Percent Complete Estimates, the Physical Measurement, the Equivalent completed units, the Earned Standards and so on.
