Interest Debt per Share
Calculate the interest debt per share, a valuation ratio that measures the amount of interest expense incurred per outstanding share of a company’s stock.
The interest debt per share ratio provides insight into how much interest a company pays on its debt relative to its shareholder base. It can help investors assess the financial burden of interest expenses on the company’s profitability.
The formula is as follows:
\[\text{Interest Debt per Share} = (\text{Interest Expense} + \text{Total Debt}) / \text{Weighted Average} (\text{Diluted}) \text{Shares}\]Interest Debt per Share in Python
