Marketing success depends on measuring the right metrics. Our free marketing calculators help you track and optimise every pound you spend on digital campaigns. Whether you're running Google Ads, Facebook campaigns, or email marketing, these tools provide instant insights without complex spreadsheets.
Return on Ad Spend (ROAS) measures how much revenue you generate for every £1 spent on advertising. A ROAS of 4:1 means you earn £4 for every £1 spent — a healthy target for most ecommerce businesses. Use our ROAS calculator to evaluate campaign performance and identify which channels deliver the best return.
Cost Per Click (CPC) tells you what you actually pay each time someone clicks your ad. Lower CPC means more traffic for your budget. Industry averages range from £0.50 for display ads to £5-10 for competitive keywords. Our CPC calculator helps you compare costs across platforms.
Conversion rate is the percentage of visitors who complete a desired action (purchase, signup, download). Average ecommerce conversion rates are 1-3%, but top performers achieve 5-10%. Use our conversion rate calculator to track improvements from A/B testing and optimisation.
One of the most important metrics for sustainable growth is Customer Lifetime Value. LTV tells you how much revenue a typical customer generates over their entire relationship with your business. Knowing your LTV helps you determine how much you can spend to acquire new customers while remaining profitable.
