1. Weights:
Generally speaking, a company's assets are financed by debt and equity. We need to calculate the weight of equity and the weight of debt.
The market value of equity (E) is also called "Market Cap". As of today, Banque Nationale de Belgique's market capitalization (E) is €142.000 Mil.
The market value of debt is typically difficult to calculate, therefore, GuruFocus uses book value of debt (D) to do the calculation. It is simplified by adding the latest one-year annual average Short-Term Debt & Capital Lease Obligation and Long-Term Debt & Capital Lease Obligation together. As of Dec. 2025, Banque Nationale de Belgique's latest one-year annual average Book Value of Debt (D) is €54148.9975 Mil.
a) weight of equity = E / (E + D) = 142.000 / (142.000 + 54148.9975) = 0.0026
b) weight of debt = D / (E + D) = 54148.9975 / (142.000 + 54148.9975) = 0.9974
2. Cost of Equity:
GuruFocus uses Capital Asset Pricing Model (CAPM) to calculate the required rate of return. The formula is:
Cost of Equity = Risk-Free Rate of Return + Beta of Asset * (Expected Return of the Market - Risk-Free Rate of Return)
a) GuruFocus uses 10-Year Treasury Constant Maturity Rate as the risk-free rate. It is updated daily. The current risk-free rate is 3.6%. Please go to Economic Indicators page for more information. Please note that we use the 10-Year Treasury Constant Maturity Rate of the country/region where the company is headquartered. If the data for that country/region is not available, then we will use the 10-Year Treasury Constant Maturity Rate of the United States as default.
b) Beta is the sensitivity of the expected excess asset returns to the expected excess market returns. Banque Nationale de Belgique's beta is 1.0018.
c) (Expected Return of the Market - Risk-Free Rate of Return) is also called market premium. GuruFocus requires market premium to be 6%.
Cost of Equity = 3.6% + 1.0018 * 6% = 9.6108%
3. Cost of Debt:
GuruFocus uses latest annual Interest Expense divided by the latest one-year annual average debt to get the simplified cost of debt.
As of Dec. 2025, Banque Nationale de Belgique's interest expense (positive number) was €5889.6 Mil. Its total Book Value of Debt (D) is €54148.9975 Mil.
Cost of Debt = 5889.6 / 54148.9975 = 10.8767%.
4. Multiply by one minus annual Tax Rate:
GuruFocus uses the most recent annual Tax Expense divided by the most recent annual Pre-Tax Income to calculate the tax rate. The calculated annual tax rate is limited to between 0% and 100%. If the calculated tax rate is higher than 100%, it is set to 100%. If the calculated tax rate is less than 0%, it is set to 0%.
The latest calculated annual Tax Rate = -0.036 / -1521.129 = 0%.
