DTC and ecommerce brands typically spend 15-35% of gross revenue on paid ads. Here is what to target at your stage.
Quick answer
Costs typically range from $1,500 to $15,000+ per month, depending on scope, channel mix, and team seniority. Senior-led work with no junior hand-offs typically commands the higher end. We break down the real cost drivers below.
Ad spend as a share of revenue varies by stage — early brands spend aggressively to grow, mature ones spend to sustain.
The right number is the one your unit economics can support, not a fixed percentage.
Track blended metrics like MER, not just platform ROAS, to know what spend actually drives.
Scale spend into proven economics; do not buy growth on a model that loses money per order.
There is no universal percentage
Brands often ask what percentage of revenue they 'should' spend on ads, but the honest answer is that it depends heavily on stage and economics. An early brand fighting for awareness may spend an aggressive share of revenue to buy growth, while a mature brand with strong organic and repeat revenue can sustain itself on far less. Copying a benchmark percentage without regard to your situation is how brands either starve growth or overspend into losses.
The percentage is an output, not an input. It falls out of your goals, your margins, and how much profitable demand you can actually capture — not the other way around.
Let unit economics set the ceiling
The real governor on ad spend is your unit economics: what a customer is worth, how quickly they pay back acquisition cost, and what margin remains. Spend that acquires customers within a healthy payback window is spend you can scale; spend that acquires them at a loss is borrowing against a future that may not arrive, no matter how good the growth chart looks. The ceiling on healthy spend is set by the economics, not by ambition.
This is why two brands with identical revenue can have very different correct ad budgets. The one with high margins and strong repeat purchase can profitably spend far more than the one with thin margins and one-time buyers.
Measure blended, scale into what works
Platform-reported ROAS overstates contribution in a privacy-constrained world, so judge spend on blended measures like marketing efficiency ratio — total revenue against total ad spend — which sit above the attribution noise. That gives you a truthful read of whether your overall spend is actually producing profitable growth rather than harvesting demand you already had.
Then scale deliberately into proven economics. Increase spend on the channels and campaigns that demonstrably pay back, and pull back where they do not. Growth built on healthy, measured economics compounds; growth bought on a loss-making model collapses the moment you stop spending.
Common mistakes that quietly kill results
These come straight from audits we run every week. If any of them stings, you’re in good company — and the fix is usually faster than you think.
Broad-matching your way to wasted spend. On Google, one unreviewed broad-match keyword can quietly burn 20-30% of budget on garbage queries. Review search terms weekly for the first month of any new campaign, then bi-weekly.
Judging ads on ROAS alone. Platform ROAS over-credits retargeting and under-credits prospecting. Watch new-customer CAC and contribution margin, or you'll keep feeding the campaign that's just harvesting people who'd buy anyway.
Scaling budget before scaling creative. Doubling spend on three tired ads just doubles your fatigue rate. The accounts that scale cleanly ship 15-30 new concepts a month and let losers die in 3 days.
Copy that describes instead of sells. 'Premium quality materials' converts nobody. Lead with the outcome, the offer, or the objection. The best hooks come from your reviews, not your brand book.

Frequently asked questions
What percentage of revenue should ecommerce spend on ads?
It varies by stage — early brands spend aggressively to grow, mature ones spend less to sustain. The right figure is whatever your unit economics can profitably support, not a fixed percentage.
How do I know if I'm spending too much on ads?
Check unit economics and blended efficiency. If acquisition cost is not recovered within a healthy payback window or your marketing efficiency ratio is unprofitable, you are spending beyond what the model supports.
Should I use ROAS to set ad budgets?
Use blended measures like marketing efficiency ratio rather than platform ROAS alone, which overstates contribution. Scale spend into proven, profitable economics rather than platform-reported returns.
