What is a good ROI? It depends on the sector. S&P 500 averages ~10%/year. Real estate: 8–12%. Paid advertising: 200–400%+ (return $3–5 per $1 spent). Always compare ROI against the cost of alternatives (opportunity cost).
FAQs
ROI = (Net Profit / Total Investment) × 100. Net Profit = Total Returns − Total Investment. Example: invest £5,000, get back £7,500 → Net Profit = £2,500 → ROI = (2,500/5,000) × 100 = 50%.
ROI shows the total return for the full period. Annualised ROI (CAGR) normalises this to a yearly rate, allowing fair comparison between investments of different durations. A 50% ROI over 2 years = ~22.5% annualised.
Marketing ROI = (Revenue from campaign − Campaign cost) / Campaign cost × 100. If you spent £1,000 and generated £4,000 in revenue: (4000-1000)/1000 × 100 = 300% ROI. Industry benchmark for paid ads is 200–400%.
