Capital Structure Inputs

How to Use This Calculator

Supply your balance sheet inputs to reveal how much of the company is financed by debt and how that compares to the equity value.

Methodology

Tutti i calcoli si basano rigorosamente sulle formule e sui dati forniti da a third-party source. La sezione di calcolo usa le regole del leverage per trasformare i valori di asset ed equity in un rapporto di debito che rispecchia la struttura di capitale.

Glossary of Variables

  • Total Assets: The total value of everything the company owns.
  • Equity: The value of shares issued by the company.
  • Debt: The amount of money borrowed by the company.
  • Debt to Equity Ratio: A measure of the company's financial leverage.

Step-by-Step Example

Assume a company has total assets of $500,000 and equity of $300,000. The debt would be $200,000, and the debt to equity ratio would be calculated as follows:

Debt = $500,000 - $300,000 = $200,000

Debt to Equity Ratio = $200,000 / $300,000 ≈ 0.67
