It is one of the first questions every founder asks. And it is one of the hardest to answer well.
Not because the answer is complicated. Because the answer depends entirely on things that are specific to your brand, your category, your margins, and your growth stage. Anyone who gives you a number without understanding those things is guessing.
What we can give you is a better way to think about the question.

Why the Question Is Hard to Answer
The instinct is to look for a benchmark. A percentage of revenue. An industry standard. A figure that tells you whether you are over or under-investing.
The problem is that benchmarks are averages. And averages hide enormous variation. A brand with high margins, strong repeat purchase rates, and a clear micro-moment to target can profitably spend far more than a brand with thin margins and a long consideration cycle. A brand in a saturated category needs to think differently from one in an underserved niche.
A benchmark tells you what other brands are doing. It does not tell you what is right for yours.
The Right Starting Point
Instead of asking “how much should we spend,” start with a different question: “what does a profitable customer cost us, and how many can we acquire at that cost?”
This reframes the conversation entirely. It moves you away from input thinking, how much goes in, towards output thinking, what comes back and over what period.
To answer it properly, you need to understand three things:
Your unit economics. What is the margin on a first purchase? What is the average order value? What does your customer lifetime value look like across six, twelve, and twenty-four months? These numbers set the ceiling for what you can sustainably spend to acquire a customer.
Your payback tolerance. How long are you willing to wait to recoup your acquisition cost? A brand with strong cash flow and high repeat purchase rates can tolerate a longer payback period, which means it can spend more aggressively upfront. A brand with thinner margins and lower repeat rates needs a tighter payback window.
Your market opportunity. How large is the addressable audience for your product? How competitive is the space? How much of the efficient inventory have you already exhausted? The answers to these questions shape how far you can scale before your cost of acquisition starts to climb.
None of these is a fixed number. They change as your brand grows, as your category evolves, and as you learn more about which customers are most valuable.
The Moment Question
There is another dimension that most brands do not factor into their spending decisions: the quality of the moment they are targeting.
Not all advertising inventory is equal. Running ads at a moment when your audience has a high propensity to buy is fundamentally more efficient than running ads when they do not. The same spend, deployed at the right moment, will return a lower cost of acquisition than the same spend spread evenly across every hour of every day.
This means that how much you should spend is partly a function of how well you understand when to spend it. A brand that has identified its highest-propensity windows can deploy budget more precisely and get more from every pound. A brand that is advertising always-on, to a broad audience, with no view on when conversion probability is elevated, will hit a ceiling sooner and at a lower spend level.
Before you increase your budget, it is worth asking whether you have fully exploited the moments where your current budget is most effective. Spending more into a poorly defined moment will not solve the problem. Spending more into a well-defined one can.
What This Means in Practice
There is no universal answer to how much a D2C brand should spend on paid media. But there is a universal principle: spend should follow understanding.
Understand your unit economics before you set a budget. Understand your highest-propensity moments before you scale spend into them. Understand which customers are most valuable before you optimise for volume.
When you have that understanding, the budget question becomes much easier to answer. Not because there is a magic number, but because you have the framework to work out what is right for your brand at this moment in its growth.
That is a very different starting point from a benchmark.
