    How to use this

    Enter the market value of equity and debt, the cost of each, and the tax rate. The calculator weights the two costs by their share of total capital, using the after-tax cost of debt because interest is tax-deductible. For Indian listed companies, cost of equity typically lands between 12% and 16% when built with CAPM (10-year G-sec yield plus beta times the equity risk premium), and cost of debt sits near the company's actual borrowing rate. The result is the discount rate a DCF uses, so small changes matter: test a range rather than trusting one number.
