Marketing ROI Calculator
Marketing ROI and PPC ROI worked out on gross profit, the way your P&L sees it. Most ROI calculators use revenue minus spend, which can make a losing campaign look like a 300% return.
Return on marketing spend, on gross profit and on revenue side by side.

- Marketing ROI = (gross profit from marketing − marketing cost) ÷ marketing cost.
- Revenue-based ROI overstates returns for any business that sells products: $60k on $15k is 300% on revenue, 140% on gross profit.
- Count every cost: fees, tools and creative, not just ad spend.
- Break-even ROAS = 1 ÷ gross margin before fees, and higher once you add them.
- Platform-credited revenue isn't all incremental. ROI on incremental sales is the one that matters.
The Marketing ROI Formula
$60,000 of revenue from marketing at a 60% gross margin is $36,000 of gross profit. Take off $15,000 of marketing cost and you have $21,000 left, a 140% marketing ROI. Every dollar spent came back as $2.40 of gross profit.
Marketing cost means all of it: ad spend, agency and freelancer fees, tools, creative production and content. Leave the fees out and ROI looks better than the business feels. This is also called ROMI, return on marketing investment.
Why Revenue-Based ROI Misleads
Most ROI calculators online use revenue minus cost. On the same numbers that gives 300% instead of 140%. The difference is the $24,000 your products cost you, and for a product business that's not optional.
It gets worse at lower margins. At 30% gross margin, $60,000 of revenue is only $18,000 of gross profit. Against $15,000 of cost, that's a 20% ROI, and revenue-based ROI would still say 300%. A campaign can look excellent on revenue and barely break even on profit.
Revenue-based ROI only makes sense where there's almost no cost of goods, like some software. For DTC brands, use gross profit. Better still, use contribution margin once shipping and payment fees are in. The monthly P&L tab of our contribution margin calculator works that out, agency fees and tools included.
PPC ROI and Break-Even CPC
$8,000 of spend buys 4,000 clicks at $2.00 each. At a 3.5% conversion rate that's 140 orders. At a $95 AOV that's $13,300 of revenue, a 1.66x ROAS. At a 60% margin, gross profit is $7,980. Add $1,000 of management and tool fees and total cost is $9,000, so the campaign loses $1,020. That's an ROI of minus 11.3%.
The fix is in two numbers the calculator gives you. Break-even ROAS here is 1.88x once fees count, not the 1.67x you'd get from margin alone. Break-even CPC is $1.75: every click is worth $1.995 of gross profit, minus $0.25 of fees per click. Pay more than that for a click and you lose money on average.
ROI vs ROAS vs MER
| Metric | Formula | What it's for |
|---|---|---|
| ROAS | Revenue ÷ ad spend | Steering campaigns inside one platform |
| MER | Total revenue ÷ total marketing cost | Whole-business efficiency, all channels, no attribution needed |
| Marketing ROI | (Gross profit − cost) ÷ cost | Whether marketing makes money |
ROAS and MER are revenue ratios. ROI is a profit percentage. A 4x ROAS at a 60% margin is a 140% ROI before fees; the same 4x at a 25% margin is exactly break-even. Use ROAS day to day, MER to check the whole business, and ROI to decide whether to spend more. Our MER calculator and ROAS calculator use the same margin logic as this page.
Incremental ROI: Sales You'd Have Got Anyway
Ad platforms credit themselves with sales that would have happened anyway: returning customers, brand searchers, people who were already going to buy. ROI on that credited revenue is always flattering.
Say platforms credit $60,000 and a holdout test shows 60% of it is truly incremental. Incremental gross profit is $21,600, and ROI drops from 140% to 44%. Still profitable. The useful number is the break-even point: here at least 41.7% of credited sales need to be incremental for the spend to pay for itself.
If you've never run a lift or holdout test, a geo test or a short pause on one channel is a good first one. Retargeting and branded search usually have the lowest incremental share; cold prospecting the highest.
What Is a Good Marketing ROI?
There's no universal figure, and anyone quoting one without asking your margin is guessing. What you can say for sure:
- 0% is break-even on marketing. Below it, marketing costs more gross profit than it creates.
- It has to cover what comes after gross profit: shipping, payment fees, overheads and your own profit. A 50% marketing ROI can still be a loss-making business.
- New customers can justify a lower first-order ROI if they come back. Our LTV:CAC calculator tells you how much lower.
About “is 3% a good ROI?”: that question usually comes from investing, where returns are yearly percentages on money you keep. Marketing ROI is a return on money you spend and don't get back, so it needs to be far higher than an investment return to be worth it.
What This Calculator Can't Tell You
- Your true incremental share. Only a lift or holdout test measures it. The input is an estimate until you run one.
- Lifetime value. These are first-order returns. Repeat purchases add to the value of a new customer.
- Brand effects. Some spend pays off later, in branded search or organic, and won't show here.
- Costs below gross margin. Shipping, payment fees and returns aren't included unless you fold them into your margin.
- Timing. Spend and revenue in the same period assumes customers buy soon after they see your marketing.
