📐 The standard ROI formula
Marketing ROI = ((Revenue – Cost) ÷ Cost) × 100. Aim for at least 300–500% (5:1 ROAS) as a baseline. Lower margins mean you need higher ROI to break even.
💰 Include all costs, not just ad spend
Creative production, agency fees, software, and staff time all eat into ROI. A campaign showing 400% ROI on media spend may show 150% once true costs are included.
📊 ROAS vs ROI — know the difference
ROAS measures revenue per £ spent (e.g. 5:1). ROI measures profit after costs. ROAS is faster to calculate; ROI is more meaningful for profitability decisions.
🔁 Factor in customer lifetime value
A campaign with a 200% ROI looks poor — until you factor in that customers return and spend again. LTV-adjusted ROI often justifies higher CPAs.
⏱️ Track time-to-ROI, not just total ROI
A campaign earning £5 profit after 6 months ties up capital. Compare the annualised return across channels so you're comparing apples to apples.
🎯 Set a target ROAS before spending
Work backwards: if your margin is 40% and you need 20% profit, your minimum ROAS is 5×. Knowing this before launch prevents chasing metrics that don't translate to profit.
📉 Negative ROI isn't always a failure
Brand campaigns and content rarely show immediate ROI but reduce CPAs across other channels over time. Mix attribution models to see the full picture.
🔍 Use multi-touch attribution
Last-click attribution overstates bottom-funnel channels and undercredits awareness. Linear or time-decay models give a more accurate view of which touchpoints truly drive ROI.

Frequently Asked Questions
The standard formula is:
Marketing ROI = ((Revenue – Cost of Investment) ÷ Cost of Investment) × 100
This calculator automates that formula, letting you input your total revenue and total marketing costs to determine your percentage return.
Marketing costs include any expenses used to execute campaigns, such as:
- Advertising spend (paid search, social ads, display)
- Creative production costs
- Staff or agency fees
- Software and tools used for campaigns
- Promotions or discounts
By including all costs can you calculate accurate ROI.
There’s no universal number, but many businesses aim for at least 5:1 ROAS (500% ROI), meaning $5 in revenue for every $1 spent. However, ideal ROI can vary by industry, business model, and margins. The calculator helps you test multiple scenarios to find a profitable benchmark.
