What EVA is trying to measure
Economic value added compares after-tax operating profit with a capital charge. A business can report positive operating profit and still destroy value if that profit is not high enough to clear the required return on the capital employed.
That is why EVA is often described as a value-creation or economic-profit measure rather than a standard accounting line item. It reframes performance around whether the business earned more than its full cost of capital, not just whether it stayed profitable on an accounting basis.
