How to use the marketing ROI calculator
- Enter total marketing spend — media budgets, content production, sponsorships, events.
- Add team and tool costs — the marketing share of salaries, agencies, and your software stack. This is the line most ROI calculations skip.
- Enter marketing-attributed revenue — from your attribution model or CRM source tracking.
- Set your blended gross margin — revenue is vanity; margin-adjusted return is sanity.
- Use it per-channel too — run each channel separately, then compare per-dollar returns to reallocate budget.
Marketing ROI: the formula and the honest version
The textbook formula — (revenue − cost) ÷ cost — hides two traps: counting revenue instead of margin, and counting media spend while ignoring the people and tools that run it. A $5,000 ad budget managed by a $1,500 slice of salaries and software is a $6,500 program. This calculator applies both corrections and returns an ROI you can take to a CFO.
What ROI should marketing produce?
A common benchmark is a 5:1 revenue-to-spend ratio ("good"), with 10:1 exceptional — but those are revenue multiples, not profit. At 60% margin, 5:1 revenue is a 200% ROI; at 25% margin the same ratio barely breaks even. That's the entire argument for margin-adjusted measurement: the ratio means nothing without the margin behind it.
The budget reallocation play
The most valuable use of this calculator isn't the headline number — it's running it once per channel with identical margin assumptions. When PPC returns $1.40 per dollar, email returns $8, and the sponsored newsletter returns $0.60, the next budget writes itself. Do this quarterly; channel efficiency drifts faster than annual planning assumes.
Attribution: pick a model, keep it constant
Last-click undercounts awareness channels; first-touch overcounts them; data-driven models are black boxes. For a small business, the practical answer is CRM source tracking plus consistent rules. The trend in a consistently-measured number beats a precise number measured differently every quarter.

Frequently Asked Questions
What is the marketing ROI formula?
ROI = (attributed revenue × gross margin − total marketing cost) ÷ total marketing cost × 100. The margin adjustment is what separates a real ROI from a revenue multiple.
What is a good marketing ROI?
Margin-adjusted, 100%+ is solid and 300%+ is strong for a blended program. As a revenue ratio, 5:1 is the common "good" benchmark — but only at healthy margins.
Should salaries count as marketing cost?
Yes — the share of team time spent on marketing, at loaded cost. A "profitable" program that quietly consumes half a salary isn't profitable; the field for it is built in.
How often should I measure marketing ROI?
Monthly for the blended number, quarterly per channel for reallocation decisions. Long-cycle B2B should also track a 12-month cumulative view so slow channels like SEO get fair credit.
Can I use this for a single campaign?
Yes — enter the campaign's spend, its share of overhead, and its attributed revenue. Same formula, shorter window.
