normally a debt equity ratio of 1:2 is acceptable. That is for every rupee of equity, Rs.2 of debt is considered as reasonable. If debt is more, interest burden will be more. If interest coverage is more (i.e., if net profit is more even after paying interest it is OK). If equity is more, and there are no debt, it means, the company is not using cheaper capital available for interest. Here, for debts, interest is paid as onetime payment; however, equity capital is a permanent liability, and requires to be serviced permanently.
