ROI Calculator
Calculate return on investment (ROI) percentage, net profit, and annualized ROI for any business decision. Whether evaluating a marketing campaign, capital equipment purchase, real estate investment, or business expansion, ROI quantifies the financial return relative to cost.
ROI is the most fundamental metric in business decision-making. A positive ROI means you earned more than you spent. A higher ROI means more efficient use of capital. Annualized ROI allows fair comparison between investments held for different time periods.
Formula
ROI (%) = (Net Profit / Cost of Investment) × 100 | Net Profit = Return - Cost | Annualized ROI = (1 + ROI)^(1/Years) - 1
Understanding ROI in Business
Return on Investment (ROI) measures the efficiency of an investment by expressing net profit as a percentage of the initial cost. It is the universal language of business decision-making — allowing comparison between completely different types of investments on a common scale.

ROI vs Other Return Metrics
ROI measures total return. Annualized ROI (CAGR) normalizes for time — a 100% ROI over 5 years is only 14.9% annually. Net Present Value (NPV) adjusts for time value of money. Internal Rate of Return (IRR) finds the discount rate that makes NPV zero. For simple business decisions, ROI is sufficient. For major capital investments comparing multi-year projects, use NPV or IRR.
Marketing ROI Calculation
Marketing ROI = (Revenue from campaign - Campaign cost) / Campaign cost × 100. A $10,000 campaign generating $40,000 in revenue: ROI = ($40,000 - $10,000) / $10,000 = 300%. Benchmark: marketing ROI above 500% is exceptional, 200-500% is good, below 100% needs optimization. Account for customer lifetime value, not just initial purchase revenue, for the most accurate marketing ROI.
Frequently Asked Questions
A good ROI depends on industry and investment type. For small businesses: 15-30% annual ROI is healthy. Marketing campaigns: 200-400%+ ROI is common for well-optimized campaigns. Equipment purchases: 30-100%+ is typical. Real estate: 8-12% annually. As a general rule, any ROI that beats your cost of capital (what you pay to borrow or the opportunity cost of equity) is profitable.
ROI % = (Net Profit / Investment Cost) × 100. Net Profit = Total Return - Investment Cost. Example: invest $5,000 in equipment, generates $8,000 in additional revenue: Net Profit = $3,000. ROI = $3,000 / $5,000 × 100 = 60%. This means you earned $0.60 for every $1.00 invested.
Annualized ROI (also called CAGR) converts total ROI to a per-year rate, enabling fair comparison between investments held for different periods. Formula: Annualized ROI = (1 + ROI)^(1/Years) - 1. A 50% ROI over 2 years = (1.50)^0.5 - 1 = 22.5% annually. Without annualizing, a 5-year investment looks more attractive than it actually is per year.
Marketing ROI = (Revenue from campaign - Campaign cost) / Campaign cost × 100. Track revenue attributable to the campaign through UTM parameters, promo codes, or CRM data. Include all campaign costs: ad spend, creative production, agency fees, and staff time. For subscription businesses, use customer lifetime value rather than first-purchase revenue for the most accurate marketing ROI.
Yes. Negative ROI means you lost money — the investment returned less than it cost. Example: invest $10,000, return only $7,000: ROI = ($7,000 - $10,000) / $10,000 × 100 = -30%. Negative ROI is a clear signal to stop or significantly change the investment strategy. Any ROI above 0% means you at least recovered your investment.
ROI measures return relative to investment cost (focused on the investor perspective). Profit margin measures profit relative to revenue (focused on the business efficiency perspective). A product selling for $100 costing $60 to produce: Profit margin = 40%, but ROI = $40/$60 = 67%. Both metrics are important but answer different business questions.
