Marketing ROI Calculator
Estimate whether your marketing is creating enough gross profit to cover its cost. This version separates revenue, gross profit, and true return so the result is easier to use in a real budget conversation.
Example numbers are included. Replace every field with your own.
Your numbers
Use one consistent period, such as a month or quarter, for spend, leads, and revenue.
Example: total advertising, agency, software, and production cost for the period.
Use qualified inquiries when possible, not every form submission.
Example: 10 customers from 50 leads is a 20% close rate.
Use expected revenue from a typical newly acquired customer.
Revenue left after the direct cost of delivering the product or service.
Estimated marketing ROI is 380% with $40,000 in projected revenue.

Gross-profit ROI
380%
Return after marketing cost, divided by marketing cost.
Revenue return
8×
Revenue divided by marketing spend, often called ROAS.
Projected customers
10
Projected revenue
$40,000
Projected gross profit
$24,000
Return after marketing
$19,000
Cost per lead
$100.00
Customer acquisition cost
$500.00
At these assumptions, marketing leaves approximately $19,000 in gross profit after marketing cost.
See how these numbers are calculated
- New customers = leads × close rate.
- Projected revenue = new customers × average revenue per customer.
- Projected gross profit = projected revenue × gross margin.
- Gross-profit ROI = (gross profit − marketing spend) ÷ marketing spend.
- Customer acquisition cost = marketing spend ÷ new customers.
This planning estimate excludes overhead, taxes, refunds, delayed revenue, and cash-flow timing.

How to Use It
A better estimate starts with numbers you can explain.
See what your current marketing spend may be producing after lead volume, close rate, customer value, and gross margin are considered together.
Step 2
Review profit before vanity metrics
The calculator estimates customer acquisition cost, gross profit after delivery costs, and the return left after marketing spend.
Step 3
Test the next improvement
Change lead volume, close rate, or customer value one at a time to see which improvement would create the biggest difference.
Read the Result Well
The number is useful when the assumptions stay visible.
Use the output to compare scenarios, ask sharper questions, and decide what deserves a closer look. It is a planning aid, not a promised result.
ROI needs margin
Revenue alone can make a campaign look healthier than it is. Gross margin gives you a more useful view of what remains after the direct cost of delivering the work.
Close rate changes lead value
Two companies can receive the same number of leads and get very different results. Better qualification and follow-up can raise the value of every inquiry without buying more traffic.
One month is a starting point
Long sales cycles, repeat purchases, seasonality, and delayed referrals can change the full return. Use a longer period when one month is unusually noisy.
Questions
Common questions about the marketing roi calculator
Straight answers about the math, the limits, and how to use the result.
How is marketing ROI calculated?
This calculator estimates gross profit from the customers attributed to marketing, subtracts marketing spend, and divides the remainder by marketing spend. The result is shown as a percentage.
Should I use revenue or gross profit?
Gross profit is usually more useful because it accounts for the direct cost of delivering the product or service. Revenue is still shown so you can see both views.
What if customers buy more than once?
Use a realistic customer value for the period you want to evaluate. If you know the average lifetime value and the retention period is reliable, you can model that separately from first-sale performance.
