ROI (Return on Investment)

ROI, or Return on Investment, is a key indicator that assesses the financial performance of an investment. It compares the net gain generated to the initial cost, expressed as a percentage, to measure the efficiency of an expenditure.

Used across all sectors, ROI helps justify budgets, prioritize projects, or optimize investments. For example, a project generating €150,000 for a cost of €100,000 has a ROI of 50%, indicating significant profitability.
