The most important CFO KPIs are Earnings Before Interest, Taxes, Depreciation, and Amortization (EBITDA) to gauge operational profitability; Net Profit Margin to assess how much revenue is retained as profit; Return on Equity (ROE) to measure financial efficiency in generating profits from shareholders' equity; and liquidity ratios such as the Current Ratio and Quick Ratio. There are many more though, but these are some of the most important ones to keep in mind.
