💹 ROI Calculator

ROI % = (Net Profit / Investment Cost) × 100 = (Return - Cost) / Cost × 100 Example: Invest ₹1,00,000, get back ₹1,45,000 Net Profit = 1,45,000 - 1,00,000 = ₹45,000 ROI = 45,000 / 1,00,000 × 100 = 45%

Annualised ROI = ((Final Value / Initial Value)^(1/Years) - 1) × 100 Example: ₹1,00,000 → ₹1,61,000 over 3 years = ((1,61,000 / 1,00,000)^(1/3) - 1) × 100 = (1.61^0.333 - 1) × 100 = (1.172 - 1) × 100 = 17.2% per year This is the Compound Annual Growth Rate (CAGR). Better than simple ROI for comparing investments of different durations.

Payback Period = Initial Investment / Annual Cash Flow Example: ₹5,00,000 investment, ₹1,20,000/year return Payback = 5,00,000 / 1,20,000 = 4.17 years Total ROI over 10 years: Total Return = 1,20,000 × 10 = ₹12,00,000 Net Profit = 12,00,000 - 5,00,000 = ₹7,00,000 ROI = 7,00,000 / 5,00,000 × 100 = 140%

ROAS (Return on Ad Spend) = Revenue / Ad Spend A ROAS of 3.6× means ₹3.60 revenue per ₹1 ad spend Marketing ROI = (Revenue × Gross Margin - Ad Spend) / Ad Spend × 100 Example: ₹50,000 spend, ₹1,80,000 revenue, 40% margin Gross Profit = 1,80,000 × 0.40 = ₹72,000 Net Profit = 72,000 - 50,000 = ₹22,000 Marketing ROI = 22,000 / 50,000 × 100 = 44%
