Calculate business return on investment
ROI = (Net Profit ÷ Total Investment) × 100. If you invested ₹1 lakh and earned ₹30,000 profit, ROI = (30,000 ÷ 100,000) × 100 = 30%.
Good ROI varies by industry and risk. Generally, 15-30% is good for most businesses. High-risk ventures should target higher returns. Compare against industry benchmarks and opportunity cost.
Marketing ROI = (Revenue from Marketing - Marketing Cost) ÷ Marketing Cost × 100. If ₹50,000 marketing spend generates ₹200,000 revenue, ROI = (200,000-50,000) ÷ 50,000 × 100 = 300%.
ROI considers profit (revenue minus all costs). ROAS (Return on Ad Spend) only considers revenue relative to ad spend. ROAS of 4:1 means ₹4 revenue per ₹1 spent, but doesn't account for other costs.
Simple ROI works for comparing investments of similar duration. For different time periods, use annualized ROI: ((1 + ROI)^(1/years) - 1) × 100. This enables fair comparison.
