Is your marketing actually profitable?
Marketing ROI: the total return on your entire marketing investment
Marketing ROI (ROMI — Return on Marketing Investment) is the net profit your marketing generates divided by what you spent, expressed as a percentage — the single number that tells you whether your entire marketing budget is profitable, not just busy. A 100% marketing ROI means you doubled your investment; 200% means you tripled it; 0% is break-even. This calculator uses gross-profit-based ROI — not the revenue-only formula many guides use — because COGS must be subtracted before any honest profitability verdict is possible. An optional LTV-adjusted view extends the analysis to account for the full lifetime value of customers acquired.
**Marketing ROI vs ROAS — two different questions.** ROAS answers "how much revenue did this campaign generate?" Marketing ROI answers "did the business make money on marketing?" ROAS of 4× sounds great, but if COGS are 80% of revenue, there is no profit after marketing spend. Marketing ROI combines revenue, COGS, and spend into a single profitability verdict.
**Why gross profit is the right denominator.** Many marketing ROI guides use total revenue: (Revenue − Spend) ÷ Spend. This overstates ROI because it ignores cost of goods. If you spent {{marketingSpend}} and generated {{revenueAttributed}} in revenue with {{cogs}} in COGS, gross profit is the true foundation — and net profit after marketing spend is what the business actually keeps.
**LTV-adjusted ROI changes the decision.** A {{marketingRoi}}% short-term ROI can look thin, but if each acquired customer is worth {{ltv}} over their lifetime, the real return on marketing is far higher. The LTV-adjusted view is what growth-stage ecommerce brands use to justify larger ad budgets — with the discipline to verify LTV assumptions with real cohort data.
**Break-even spend is the planning guardrail.** The break-even marketing spend equals your gross profit — the point where every extra dollar spent becomes a loss. Use it as the hard ceiling when setting channel budgets.

How it works
From spend and revenue to a profitability verdict
Three core inputs, two optional for LTV view.
02
Enter COGS
Cost of goods for the attributed revenue — this is what separates gross profit from revenue.
03
Optionally add LTV data
Enter average customer LTV and the number of new customers to see an LTV-adjusted ROI that factors in lifetime value.
04
Read your profitability verdict
The calculator shows marketing ROI, revenue multiple, gross margin, break-even spend, and net profit together — the full P&L view in one place.

Formula
Exactly what the calculator computes
Standard marketing ROI math — gross-profit based for accuracy.
01
Gross Profit
Gross Profit = Revenue Attributed − Cost of Goods Sold
The starting point. At {{revenueAttributed}} revenue and {{cogs}} COGS, gross profit = {{grossProfit}}.
02
Marketing ROI (ROMI)
Marketing ROI = (Gross Profit − Marketing Spend) ÷ Marketing Spend × 100
Net profit from marketing as a percentage of what you spent. 100% = you doubled your spend. 0% = break-even. Negative = losing money on marketing.
03
Revenue Multiple
Revenue Multiple = Revenue ÷ Marketing Spend
Revenue generated per unit of spend. This is blended ROAS across all channels — useful for a quick high-level check, but always interpret it with gross margin in mind.
04
Break-Even Marketing Spend
Break-Even Spend = Gross Profit
The level of spend where net profit hits zero. Any spending above gross profit is a net loss on marketing.
05
LTV-Adjusted ROI
LTV-Adjusted ROI = (Customers × LTV − Marketing Spend) ÷ Marketing Spend × 100
Incorporates the full lifetime value of acquired customers. Use this to justify investment in acquisition that looks thin on first-order ROI alone — but verify LTV with real cohort data before scaling spend.
Worked example
A {{marketingSpend}} quarter — profitable or not?
A typical ecommerce brand spending across Google, Meta, and email.
Scenario
A DTC brand spent $5,000.00 on Google and Meta ads and attributed $20,000.00 in revenue. Their products have $40.00% gross margin (COGS: $12,000.00).
1
Step 1 — Gross profit
$20,000.00 revenue − $12,000.00 COGS = $8,000.00 gross profit. Gross margin = $40.00%.
Gross profit: $8,000.00
2
Step 2 — Marketing ROI
Net profit = $8,000.00 − $5,000.00 = $3,000.00. Marketing ROI = $3,000.00 ÷ $5,000.00 × 100 = $60.00%.
Marketing ROI: $60.00%
3
Step 3 — Revenue multiple
$20,000.00 ÷ $5,000.00 = $4.00×. For every dollar of marketing, the brand generated $4.00 in revenue.
Revenue multiple: $4.00×
4
Step 4 — LTV-adjusted view (optional)
The brand acquired $100.00 new customers with an average LTV of $120.00. LTV-adjusted ROI = ($100.00 × $120.00 − $5,000.00) ÷ $5,000.00 × 100 = $140.00%.
LTV-adjusted ROI: $140.00%
The takeaway
A $60.00% short-term ROI is positive but below the 200% mark most scaling brands target. With LTV factored in, the real return is $140.00% — a strong case for increasing budget once LTV is validated with cohort data.

Common mistakes
How marketing ROI calculations go wrong
Using revenue instead of gross profit in the ROI formula
Why it matters
The common formula (Revenue − Spend) ÷ Spend uses revenue, ignoring COGS. This overstates ROI significantly. A brand with 40% gross margin and 4× ROAS actually has a 60% marketing ROI, not 300%.
Fix
Always subtract COGS before calculating ROI. Marketing ROI = (Gross Profit − Spend) ÷ Spend.
Attributing all revenue to marketing
Why it matters
Some sales come from word-of-mouth, repeat customers, and organic channels that require no marginal spend. Attributing everything to marketing spend inflates ROI.
Fix
Use incrementality testing or a conservative multi-touch attribution model to estimate what revenue would have happened without the marketing.
Ignoring LTV when evaluating acquisition campaigns
Why it matters
A first-order marketing ROI of 60% looks mediocre, but if those customers are worth 3× their first order in LTV, the real ROI is much higher. Cutting "unprofitable" campaigns based on first-order ROI destroys long-term value.
Fix
Always check LTV-adjusted ROI for acquisition campaigns. Use real cohort data to verify LTV before assuming it in planning.
Confusing marketing ROI with ROAS
Why it matters
ROAS is revenue ÷ ad spend — it says nothing about profit. A 5× ROAS at 15% gross margin means you are losing money on marketing. ROAS is a campaign efficiency metric; ROI is a profitability metric.
Fix
Use ROAS for campaign comparison and optimisation. Use marketing ROI (gross-profit based) to judge whether marketing is profitable for the business.
Not including all marketing costs
Why it matters
Ad spend is only one line item. Agency retainers, design and creative production, tool subscriptions, influencer fees, and headcount all belong in marketing spend. Under-counting spend flatters the ROI.
Fix
Include every dollar that exists to drive new or returning customer revenue: ad spend, fees, creative, tools, and relevant team time.
Expecting high ROI in growth mode
Why it matters
During rapid growth, brands intentionally run negative or low marketing ROI because they are buying future LTV. Judging a growth-phase brand by short-term ROI is the wrong frame.
Fix
In growth mode, measure LTV-adjusted ROI and CAC payback period instead of short-term ROI. Set a threshold for when LTV:CAC and payback become healthy, then scale.
Tips
How to improve your marketing ROI
Raise margin before scaling spend
Marketing ROI = (Gross Profit − Spend) ÷ Spend. A higher gross margin means every extra revenue dollar generates more net profit — often more impactful than cutting CPA.
Add email to lift ROI
Email marketing often achieves 2000–5000% ROI. Including it in your total marketing mix raises your blended ROI significantly relative to pure paid acquisition.
Split acquisition from retention spend
Blending acquisition and retention spend into one marketing ROI hides whether acquisition or retention is the profit driver. Run separate P&Ls for each.
Validate LTV with cohort data
LTV-adjusted ROI only improves decisions if the LTV number is based on real cohort data. Use the LTV CAC Calculator to cross-check your LTV figure before scaling spend.
Cap spend at gross profit
Your break-even marketing spend equals your gross profit. Keep total spend below this hard ceiling — above it, every extra dollar is a net loss.
Compare ROI by channel
A 200% blended ROI can hide a 50% ROI on Meta and a 500% ROI on email. Shift budget toward the highest-ROI channels once you have clean attribution.

Glossary
Marketing ROI vocabulary
Every important term you'll encounter in this calculator and the broader topic.
- Marketing ROI (ROMI)
- Net profit from marketing divided by marketing spend, expressed as a percentage. 100% = you doubled spend; 0% = break-even.
- Gross Profit
- Revenue minus cost of goods sold. The foundation of marketing ROI — not revenue.
- Revenue Multiple
- Revenue generated per unit of marketing spend. Same as blended ROAS. Useful but needs gross margin context to judge profitability.
- LTV-Adjusted ROI
- ROI calculated using the full lifetime value of acquired customers rather than just first-order revenue.
- Break-Even Marketing Spend
- The maximum total marketing spend where net profit is zero — equal to gross profit from attributed revenue.
- ROAS
- Return on Ad Spend = Revenue ÷ Ad Spend. A revenue metric, not a profit metric. Needs margin context to judge business health.
- Blended ROI
- Total marketing ROI across all channels combined — as opposed to channel-specific ROI.
- Incrementality
- The additional revenue caused by marketing spend, above what would have happened without it. The true measure of marketing impact.
- Attribution
- The method for assigning credit for conversions to marketing channels and campaigns. Different models give different ROI figures for the same spend.
Help & answers
Frequently asked questions
Everything you need to know about how the Marketing ROI Calculator works.
01What is marketing ROI?
Marketing ROI (or ROMI — Return on Marketing Investment) is the net profit generated by your marketing spend, divided by that spend. The formula is: Marketing ROI = (Gross Profit − Marketing Spend) ÷ Marketing Spend × 100. A 100% ROI means you doubled your investment; 0% is break-even; negative is a loss.
02What is the marketing ROI formula?
Marketing ROI = (Gross Profit − Marketing Spend) ÷ Marketing Spend × 100. Gross Profit = Revenue Attributed − Cost of Goods. Many guides use revenue instead of gross profit — this overstates ROI significantly because it ignores product cost.
03What is a good marketing ROI for ecommerce?
Most scaling ecommerce brands target 200–500% marketing ROI (meaning you get 2–5× your spend back in profit). Below 100% means each marketing dollar generates less than a dollar of profit. Email typically achieves 2000%+; paid social runs 100–300%; paid search 200–400%. The right benchmark depends on your channel mix and margin.
04What is the difference between marketing ROI and ROAS?
ROAS (Return on Ad Spend) = Revenue ÷ Ad Spend. It is a revenue metric, not a profit metric. A 4× ROAS at 20% gross margin means you are losing money after COGS and ad spend. Marketing ROI subtracts COGS and spend to show actual profit — the meaningful business number.
05What is LTV-adjusted marketing ROI?
LTV-adjusted ROI factors in the full lifetime value of customers acquired through marketing, not just first-order revenue. Formula: (Customers × LTV − Marketing Spend) ÷ Marketing Spend × 100. This is the right frame for growth-stage brands that acquire customers at thin short-term margins but strong lifetime returns.
06What should I include in marketing spend?
All spend that exists to drive new or returning customer revenue: ad spend across all platforms, agency fees, creative production, influencer fees, tool subscriptions (email platform, analytics), and a portion of marketing headcount salary. Under-counting spend by using only ad spend flatters the ROI number.
07How do I calculate break-even marketing spend?
Break-even marketing spend equals your gross profit. If revenue is {{revenueAttributed}} and COGS is {{cogs}}, gross profit is {{grossProfit}} — that is the maximum you can spend on marketing before net profit turns negative.
08How do I improve marketing ROI?
Four levers: raise gross margin (every extra margin point flows directly to ROI); improve conversion rates (more revenue at the same spend); reduce cost through better targeting and creative; and invest in higher-ROI channels like email and SEO where cost scales slowly.
09What is ROMI?
ROMI stands for Return on Marketing Investment — another name for marketing ROI. The industry uses both terms interchangeably. Calcrux uses marketing ROI; you may see ROMI in strategy documents or academic marketing literature.
10Should I use blended or channel-specific marketing ROI?
Use both. Blended marketing ROI gives a health check on total spend. Channel-specific ROI reveals which channels to grow and which to cut. A healthy blended ROI can hide a failing channel if high-ROI email or SEO offsets poor paid performance.
11Can I use this for B2B marketing ROI?
Yes — the math is the same. Replace "revenue attributed" with pipeline revenue or contract value attributed to marketing campaigns. COGS in B2B is typically service delivery cost or cost of the product sold. The gross-profit-based formula applies across business models.
12Does this calculator work in any currency?
Yes. Enter every value in your own currency and all results appear in that currency. No exchange rates or conversions are needed — percentages and ratios are universal.
