## What is VAC in project management formula?

**Variance at Completion** (VAC) Formula

The VAC formula is a simple subtraction formula resulting in a monetary value. It shows the total cost planned (budget at Completion or BAC) minus the total cost now predicted (Estimate at Completion or EAC).

## What is VAC in earned value analysis?

**Variance at Completion** (VAC) is a key performance indicator in Earned Value Project Management that shows the difference between the Budget at Completion (BAC) and the Estimate at Completion (EAC): VAC = BAC – EAC.

## What is the variance at completion vac?

Variance at Completion (VAC) is **a projection of the budget surplus or deficit**. It is expressed as the difference of the Budget at Completion (BAC) to the Estimate At Completion (EAC). This project management concept is the difference between the expected or baseline cost of the project and the current estimated cost.

## What is complete variance?

**A projection of the amount of budget deficit or surplus expressed as the difference between the budget at completion and the estimate at completion**.

## What is positive vac?

A positive VAC indicates **the project will not utilize the allocated budget**. This may allow for additional components to be added to the scope of the project.

## How do you calculate SV in project management?

Schedule Variance (SV)

Schedule Variance can be calculated using the following formula: **Schedule Variance (SV) = Earned Value (EV) – Planned Value (PV)** **Schedule Variance (SV) = BCWP – BCWS**.

## How do you calculate planned value?

The formula for calculating Planned Value is: **PV = % of project completed (planned) x Budget at completion (BAC – Budget at Completion which is the total budget of the project)**. If you are lucky enough to have a linear project where time and cost are the same every day to completion, Planned Value will be very simple.

## What are the differences between BAC and EAC?

**BAC stands for Budgeted cost At Completion**. EAC stands for Estimated cost At Completion. BAC is an exogeneous variable i.e. given for the context of the project which needs to be adhered. EAC is a performance parameter which can be computed at any stage of the project based on historical performance.
