Marketing ROI Calculator
Estimate the return on investment from a marketing campaign using revenue, campaign cost, gross margin and additional overheads.
Overview
A marketing ROI calculator helps you estimate whether a campaign is generating enough profit to justify the spend. Enter your attributed revenue, marketing spend, gross margin, additional costs, leads and customers to see ROI, ROAS and key efficiency metrics.
How it works
The calculator first estimates gross profit by applying your gross margin to campaign revenue. It then adds marketing spend and any extra campaign costs to get total investment. Net profit is calculated by subtracting total investment from gross profit, and ROI is net profit divided by total investment. It also shows ROAS, cost per lead and cost per customer for a broader view of campaign performance.

Frequently asked questions
What does this marketing ROI calculator estimate?
It estimates campaign ROI based on attributed revenue, gross margin, marketing spend and extra campaign costs.
What is the difference between ROI and ROAS?
ROI looks at profit after costs, while ROAS compares revenue to ad spend without applying margin or broader costs.
Why does gross margin matter in ROI?
Revenue is not the same as profit. Gross margin helps convert revenue into an estimated profit figure before marketing costs are deducted.
Should I include repeat purchases in campaign revenue?
You can, as long as your attribution method supports it and you apply the same approach consistently.
What costs should I include?
Include ad spend and any direct campaign costs such as agency fees, creative production, landing page tools or fulfilment costs tied to the campaign.
Can I use this calculator for any channel?
Yes. It can be used for paid search, social ads, email, influencer campaigns, events or other marketing channels.
