8 Financial Ratios Investors Can Use to Evaluate Stocks

NEW YORK, Sept. 8, 2026 — Evaluating a stock requires more than looking at its share price or the latest earnings report. Financial ratios give investors a way to examine different parts of a company’s finances, from the price investors are paying for its earnings to the amount of debt it carries.

No single ratio tells the full story. Investors can get a more complete picture by comparing several ratios, reviewing how they have changed over time and looking at similar companies in the same industry. The right comparison also matters because a ratio that is normal for one sector may look very different in another.

Valuation Ratios Put Stock Prices in Context

The price-to-earnings ratio, or P/E, compares a company’s share price with its earnings per share. It shows how much investors are paying for each dollar of earnings. A higher P/E can reflect expectations for future earnings growth, while a lower P/E can indicate that investors are assigning a lower valuation to the company. Neither figure alone determines whether a stock is expensive or inexpensive.

The price-to-sales ratio offers another way to examine valuation by comparing a company’s market value with its revenue. This can be useful when earnings are low or negative, and the P/E ratio cannot provide a meaningful comparison. Looking at both measures alongside industry peers can give investors more context when assessing a stock’s valuation.

Profit Ratios Show How the Business Performs

Profit margin measures the portion of revenue that remains as profit after expenses. For example, a company with $10 million in revenue and $1 million in profit has a 10% profit margin. Comparing the figure over several years can show whether the business is retaining more or less of its revenue as profit.

The EBITDA-to-sales ratio provides another view of operating performance. EBITDA stands for earnings before interest, taxes, depreciation, and amortization. Comparing EBITDA with sales allows investors to see how much operating earnings a company generates relative to its revenue before those expenses are taken into account. This ratio can be especially useful when comparing businesses with different financing or asset structures.

Cash Flow and Dividends Tell Another Story

The price-to-free-cash-flow ratio compares a company’s share price with its free cash flow per share. Free cash flow is the money left after a business pays for its operating needs and capital expenditures. Investors can examine this figure to see how much cash a company generates relative to the value assigned to its shares.

The dividend payout ratio measures the portion of a company’s net income that it pays to shareholders as dividends. A high payout ratio means a larger share of earnings is being distributed, leaving less available for reinvestment. A lower ratio leaves more earnings within the business. For investors seeking dividend income, the measure can help show how much of the company’s profit is being returned to shareholders.

Debt and Liquidity Reveal Financial Obligations

The debt-to-equity ratio compares a company’s debt with shareholders’ equity and gives investors an indication of how heavily the business relies on debt financing. A higher ratio means debt represents a larger share of the company’s financing relative to equity. The figure needs to be compared with industry peers because debt levels can vary significantly between sectors.

Liquidity ratios provide a view of a company’s ability to meet short-term obligations. The current ratio compares current assets with current liabilities, while the quick ratio uses assets that can be converted into cash more readily, such as cash, marketable securities and accounts receivable. Reviewing these measures alongside profitability, cash flow and debt ratios can give investors a fuller picture of a company’s financial position.
