Frequently Asked Questions

Common questions about ROI Marketing calculations

How is marketing ROI calculated?
Marketing ROI = (Net Profit from Campaign ÷ Total Marketing Investment) × 100. Net Profit = Revenue − COGS − Marketing Costs. A 200% ROI means you earned 2 units for every 1 unit invested (i.e., tripled your money). ROI > 0% is profitable; ROI < 0% means the campaign lost money. Most businesses target 300–500% ROI (5:1 return).
What is the difference between ROI and ROAS?
ROI (Return on Investment) accounts for all costs including COGS and overhead: ROI = (Revenue − All Costs) ÷ All Costs × 100. ROAS (Return on Ad Spend) only accounts for ad spend: ROAS = Revenue ÷ Ad Spend. ROAS is higher than ROI and is commonly used by media buyers. A 4x ROAS might mean 0% ROI if margins are thin. Always know which metric you're using. Break-even ROAS = 1 ÷ Profit Margin. If your margin is 40%, break-even ROAS = 2.5x.
What is a good marketing ROI?
Benchmarks vary by channel and industry: SEO 200–1000%+, Email marketing 3800%+ (industry average — varies by market and list quality), Social media ads 100–300%, Display ads 50–150%, Influencer marketing 200–600%. A useful benchmark is your LTV:CAC ratio — ideally 3:1 or higher (acquire customers for 1/3 their lifetime value). Under 1:1 is unsustainable; under 3:1 means slow growth. Note: the 3:1 LTV:CAC benchmark is widely used in SaaS and e-commerce. Traditional retail and service businesses may operate profitably at different ratios depending on margin structure and business model.
What is Customer Lifetime Value (LTV)?
LTV = Average Purchase Value × Purchase Frequency × Customer Lifespan (years). A customer who buys 100-unit items 3 times per year for 2 years has LTV = 600 units. Margin-adjusted LTV (what matters for profitability) = LTV × Gross Margin. If margin is 50%, this customer's profitable LTV is 300 units. Your maximum sustainable CPA should be significantly below this figure.
How do I improve marketing ROI?
Key levers: (1) Increase conversion rate (better landing pages, offers, targeting). (2) Increase average order value (upsells, bundles, anchoring). (3) Increase repeat purchase rate (retention emails, loyalty programs). (4) Reduce CPA (better targeting, creative testing, Quality Score). (5) Focus on high-LTV customer segments. (6) Shift budget from low-ROI to high-ROI channels based on data.
What is attribution and why does it matter?
Attribution determines how conversion credit is assigned across marketing touchpoints. Last-click gives 100% credit to the final touchpoint (common default in most ad platforms). First-click credits the channel that introduced the customer. Linear splits credit equally across all touchpoints. Data-driven uses algorithmic modelling (Google Analytics 4 default). This calculator uses last-click attribution. If you run multi-touch campaigns (e.g., SEO + retargeting + email), your actual per-channel ROI may differ significantly under other models.
