What you get
Every return figure from two numbers.
Spend and revenue give you ROI and ROAS. Your margin turns them into profit and a break-even target, and customer numbers add CAC and LTV:CAC.

Why it matters
Revenue is not the same as return.
A campaign can bring in plenty of sales and still lose money. Knowing the real return tells you where the next budget should go.
Margin
A good ROAS can still lose money
At a 30% margin, a 3x ROAS loses money once you pay for what you sold. Break-even ROAS shows the line you have to clear.
Budget
Compare channels on one scale
Search, social, email and content all turn into the same ROI, ROAS and CAC, so you can move spend to what pays back.
Growth
Customers outlast the campaign
LTV:CAC shows whether a customer is worth more than they cost to win, even when the first sale alone does not cover it.

FAQ
Questions, answered.
Marketing ROI is revenue minus marketing spend, divided by marketing spend. Spend 1,000 and bring in 3,200 and your ROI is 2,200 divided by 1,000, or 220%. A positive ROI means the campaign brought in more than it cost.
ROMI stands for return on marketing investment. It is the same idea as marketing ROI: what your marketing returned compared with what it cost. This calculator shows it both on revenue and on gross profit.
ROAS, return on ad spend, is revenue divided by spend, written as a multiple such as 3.2x. ROI takes the spend back out first, so a 3.2x ROAS is a 220% ROI. Ad platforms such as Google Ads and Meta report ROAS; finance teams usually ask for ROI.
Revenue is not profit. If you keep 40 cents of every dollar of sales after the cost of the goods, only that 40 cents can pay back your marketing. Profit-based ROI uses revenue times margin, minus spend, divided by spend. Leave the margin blank and the calculator treats all revenue as profit.
Break-even ROAS is the return on ad spend at which a campaign exactly pays for itself after margin. It is 1 divided by your margin: at a 40% margin you need 2.5x, and at a 25% margin you need 4x. Below it, every sale loses money once the spend is counted.
CAC is marketing spend divided by the number of new customers it won. Spend 1,000 to win 20 customers and your CAC is 50. Many teams also add salaries and tools to the spend for a fully loaded CAC.
A common rule of thumb, widely used for SaaS and subscription businesses, is 3:1 or better: a customer brings in at least three times what it cost to win them. Under 1:1 you lose money on each customer. Far above 5:1 can mean you are spending too little to grow.
It is the payback on lifetime value: what one customer brings in over their whole time with you, times your margin, minus the cost of winning them. A positive number means each new customer pays back their acquisition cost over time.
It works only from the numbers you enter. Revenue-only ROI ignores the cost of goods, salaries, agency fees and tools, and the result is only as good as how you attribute revenue to marketing. Treat it as a clear first read, not an audited figure.
