Type IV: mediterranean, brown or black hair Type III: medium skin, dark blonde or brown hair Type II: light skin, blonde or light brown hair, sometimes freckles Type I: very light skin, light blonde or red hair, freckles UV rays also cause sunburn when its cloudy be careful.Ī Use protection: sunscreen, clothes, hat, sunglasses and shade. The calculated value is an approximation only. Use tanning calculator to calculate maximum sun tanning time based on skin type, UV index (UVI), and sun protection factor (SPF) (Avoid sunburn by knowing your skin type, UV index and SP factor.) Example 3:Ī burn rate lower than 1 means the project is currently under budget.Calculate Sun Protection And Sun Tanning Time. Keeping track of the burn rate will ensure it stays in line throughout the project timeline. Here, the burn rate is equal to 1 which means the project budget is being expended in accordance with what was originally planned. Steps should be taken to get the project back on track. The result here indicates the burn rate is greater than one and so the project is over budget. Here are some examples to highlight the burn rate formula and how to complete the burn rate calculation properly. While these are gathered for individual elements, they are used to look at the cumulative amounts through the data date. These metrics should be collected up to the data date to perform the most accurate calculations. Earned Value is the percentage of the work completed multiplied by the budgeted costs. Actual Costs are the cost of the work completed. The two values you need are Actual Cost and Earned Value. The burn rate calculation is the process of determining what the required earned value metrics of your project are. If you fail to track the burn rate of your project with the burn rate formula, you run the risk of your project expending the budget too quickly and potentially running out of funding. If you are expending your project budget at a faster rate than what was initially planned, you would have to notify your key stakeholders and develop a plan to get the project back in line with the original budget expenditure rate. This is vital information when communicating with stakeholders. It is important to track the burn rate of a project to determine how well a sprint is progressing. Be careful not to get these two formulas confused as the answers derived from solving the burn rate formula are then interpreted differently than CPI. You may have noticed the burn rate formula is the opposite of the Cost Performance Index (CPI) formula which is EV/AC. This is a good position to be in because it means the original estimations were accurate and the project is progressing as intended. Burn Rate is equal to 1Ī burn rate equal to 1 means the budget is being expended in accordance with what was originally planned. Just like with an over-budget project, determine if the burn rate is greater than 1, it would be a good idea to capture all of the project work performance data to analyze what steps led to being under budget. Burn Rate is less than 1Ī burn rate of less than one is the best news! This means the project is being expended at a slower than planned pace and is currently under budget. Also, pay close attention to the factors that led to the project being over budget to assess where improvements could be made on future, similar projects. Once this is determined, steps should be taken to bring the project back on track so the budget can remain viable. It is “burning through” the budget at a faster pace than what was planned. If the project burn rate is greater than 1 then the project is currently over budget. The results of this formula are translated as follows: Burn Rate is greater than 1 The burn rate formula is Actual Cost (AC) divided by Earned Value (EV) or: AC / EV.Īccording to the PMBOK ® Guide, Actual Cost (AC) is the realized cost incurred for the work performed on an activity during a specific time period and Earned Value (EV) is the measure of work performed expressed in terms of the budget authorized for that work.
