Frequently Asked Questions
How do you calculate marketing ROI?
Marketing ROI is calculated as: ROI = (Revenue Generated - Marketing Cost) / Marketing Cost × 100. For example, if you spend $10,000 on marketing and generate $50,000 in revenue, your ROI is (50,000 - 10,000) / 10,000 × 100 = 400%. A positive ROI means your marketing is profitable.
What is a good marketing ROI?
A good marketing ROI varies by industry and channel. Generally, a 5:1 ratio (500% ROI) is considered strong, while 10:1 (1000% ROI) is exceptional. For paid advertising, a 4:1 ROAS is typically the minimum target. Content marketing and SEO often have higher ROI but take longer to realize returns.
What is ROAS and how is it different from ROI?
ROAS (Return on Ad Spend) measures revenue generated per dollar spent: ROAS = Revenue / Ad Spend. ROI measures profit relative to investment. A 4x ROAS means $4 revenue for every $1 spent. The key difference is ROI accounts for profit (after costs), while ROAS only looks at revenue.
What is a good CLV:CAC ratio?
The ideal CLV:CAC ratio is 3:1 or higher, meaning customer lifetime value is at least 3x the cost to acquire them. A ratio below 1:1 means you're losing money on customer acquisition. Ratios of 5:1 or higher may indicate you're under-investing in growth.
How do you calculate Customer Acquisition Cost (CAC)?
CAC = Total Marketing & Sales Spend / Number of New Customers Acquired. Include all costs: advertising, content creation, marketing tools, sales team salaries, and agency fees. Calculate CAC by channel to identify which channels acquire customers most efficiently.
