Calculate your marketing return on investment and optimize your ad spend.
Traffic, impressions, and follower counts are vanity metrics. Return on investment is the only number that tells you whether your marketing is actually working. Our free marketing roi calculator puts the key performance metrics in one place so you can make decisions based on data, not instinct.
Whether you’re evaluating a paid search campaign, an SEO investment, a social media spend, or a full marketing budget, these calculations tell you what’s working and what needs to change.
ROI measures the percentage gain or loss relative to your marketing spend:
ROI = ((Revenue Generated - Marketing Spend) / Marketing Spend) × 100
A 200% ROI means you made $3 for every $1 spent — $2 profit after recovering the spend. A negative ROI means the channel is costing you more than it generates. Knowing your ROI per channel lets you shift budget from underperforming areas to those with proven returns.
What’s a good marketing ROI? Industry benchmarks vary, but a general target is 5:1 — $5 in revenue for every $1 spent. E-commerce and high-margin services often achieve higher ratios. Local services and lower-margin businesses may target lower ratios with higher absolute revenue.
ROAS measures revenue generated for every dollar spent on advertising specifically:
ROAS = Revenue from Ads / Ad Spend
A ROAS of 4 means $4 in revenue for every $1 in ad spend. ROAS doesn’t account for other costs (production, margins, overhead), so it’s best used to compare campaigns against each other and against platform benchmarks. Google Ads benchmarks for e-commerce typically target 4–8x ROAS depending on margins.
CPA tells you how much you’re paying to acquire each customer or lead:
CPA = Total Marketing Spend / Number of Conversions
Your CPA target depends on your average order value and customer lifetime value. If a customer is worth $500 to your business, a CPA of $50 is excellent. The same $50 CPA is unsustainable if average order value is $60. Knowing your CPA and comparing it to customer LTV is the foundation of sustainable paid media strategy.
Understanding CLV transforms how you think about acquisition cost. A customer who buys once at $100 justifies a different CPA than one who buys monthly at $100 for three years. If you’re not factoring CLV into your CPA targets, you’re likely either over- or under-investing in acquisition.
Enter your campaign spend, revenue generated, and number of conversions. The calculator instantly returns your ROI, ROAS, and CPA alongside context for whether those numbers indicate strong performance or need improvement.
Use it to:
A good ROI starts with the right strategy. If your current numbers aren’t where they need to be, the levers are:
Reduce cost: Improve Quality Score in paid search, tighten audience targeting, eliminate wasted spend on irrelevant keywords.
Increase revenue per conversion: Improve landing page conversion rates, increase average order value, refine your offer.
Improve attribution: Many businesses undercount revenue from marketing channels that assisted conversions without directly closing them. Better attribution often reveals that channels appearing to underperform are actually driving significant value.
If you’re running paid media and struggling to hit your ROAS targets, our team can audit your campaigns and identify where budget is being wasted. Talk to us about a review.
ROI accounts for total marketing investment and total profit. ROAS measures only advertising revenue against ad spend, without factoring in other costs. Use ROAS to compare ad campaigns against each other; use ROI to evaluate whether your overall marketing investment is worthwhile.
Both. Overall marketing ROI tells you whether the total investment is justified. Channel-level ROI tells you where to shift budget. Brands that only track blended ROI often subsidize underperforming channels with strong ones without realizing it.
SEO ROI is harder to calculate than paid media because the investment is front-loaded and the returns compound over time. Estimate the traffic value of your organic rankings using average CPC for those keywords as a proxy for what you'd pay for the same traffic in paid search.
Typically 6–12 months before organic traffic meaningfully exceeds the investment. SEO compounds — rankings and traffic continue growing past that point without proportional increases in spend, which is why the long-term ROI typically outperforms paid media significantly.
