Looking at the above formula of calculating CPI, a more direct formula for the burn rate would be: Burn Rate = 1/CPI = 1/EV/AC = AC/EV. Where AC is the Actual Cost, and EV is the Earned Value. Example of Calculating the Burn Rate. Assuming the Earned Value of a construction project so far is $3,000,000, and the Actual Cost is $3,500,000. Then: Burn Rate = AC/EV = $3,500,000/$3,000,000 = 1.16 Resuscitation endpoints and monitoring: Urine output: 0.5 mL/kg/hr urine output in adults (50-100cc/hr) and 0.5–1.0 mL/kg/hr in children <30 kg. Heart rate: HR<110 in adults usually indicates adequate volume. Narrowed pulse pressure provides an earlier indication of shock than does systolic blood pressure alone. In earned value management, burn rate is calculated via the formula, 1/CPI, where CPI stands for Cost Performance Index, which is equal to Earned Value / Actual Cost. Other uses [ edit ] The term burn rate is also used in a number of scientific settings: [ citation needed ] In biology, it can refer to a person's basic metabolic rate
