Capital budgeting is one of the most crucial organisational tools for executing operational, business and corporate strategy. Manufacturing companies derive their profits from fixed assets that also deteriorate over time. This requires them to invest large amounts of capital to both maintain and expand their asset base. A number of studies both historic and recent produce conflicting results on the relationship between capital budgeting practices and financial performance.This study sets out to identify the current capital budgeting practices in the manufacturing/capital intensive companies operating in the South African environment, and determine the relationship between the financial performance and capital budgeting practices. The implications of the type of capital expenditure (i.e. maintenance and expansionary) are also discussed.The study was completed using primary and secondary data. Primary data consisted of capital budgeting practices data in some of the private and state-owned enterprises that was source using a survey questionnaire. The secondary data was sourced from financial statements on the McGregor BFA® database.The major finding of this research study was that, given the sufficient sub-sector analysis, there is a positive relationship between capital budgeting practices and financial performance. There were no specific individual practices that yielded significantly returns.
