Most published benchmarks put marketing spend for a mid-market company somewhere between 5 and 12 percent of revenue, and that range is where the conversation usually starts when a PE board asks the question. It is the wrong starting point. The right marketing budget for a PE-backed company is not a percentage of revenue; it is the output of three inputs: the revenue growth the value-creation plan requires, the unit economics of the channels available to produce it, and the current condition of the commercial engine the money will run through. Companies that budget from benchmarks fund their existing habits. Companies that budget from the plan fund outcomes.
This guide is for the people on either side of the board table when the question comes up: sponsors underwriting a growth plan, portfolio CEOs defending a number, and CFOs asked to reconcile the two. It is the question every new portfolio CEO gets asked in the first board cycle, and the quality of the answer says a great deal about the commercial function underneath it.
Benchmarks describe averages across companies with different strategies, different channel economics, and different owners. A PE-backed company is not an average company. It has a dated plan: a specific revenue number, by a specific year, underwritten at a specific multiple. The budget question is therefore not "what do companies like us spend" but "what does it cost to produce the growth this plan requires, through these channels, at these unit economics." Those are different questions with different answers.
The benchmark answer also hides the condition of the engine. Two companies can each spend 8 percent of revenue and get wildly different returns because one has clean attribution, a working referral program, and owned channels that compound, while the other is renting leads and cannot say which half of its spend produces anything. In one PE-backed services company we audited, 38 percent of revenue arrived through word of mouth that no system tracked. Any percentage-of-revenue discussion at that company was fiction until the measurement existed, because the denominator of every efficiency number was wrong.
Sponsors themselves have moved past the cost-line view. In S&P Global Market Intelligence's 2026 Private Equity Survey, 71 percent of general partners said they prioritize operational value creation over financial engineering, and 53 percent of limited partners said the same about the funds they back. Marketing spend is one of the few operational levers that acts directly on revenue. Treating it as a benchmarked overhead item is a habit from a different era of the asset class.
Start with the plan math. Work backward from the deal model: the revenue target implies a customer volume, the customer volume implies a pipeline, and the pipeline implies a quantity of demand that existing channels either can or cannot produce. Costing that demand, channel by channel, produces a budget with a defensible logic. If the resulting number is far above what the P&L can carry, that is not a budgeting problem; it is a signal that the plan assumes channel economics the company does not yet have, which is worth knowing in year one rather than year three.
Then apply the unit economics. Every channel has a cost to acquire a customer and a payback period, and the budget should be allocated as a portfolio of those economics, not as a lump. Bought demand, such as paid search and purchased leads, delivers quickly, scales linearly, and stops the day the spending stops. Owned demand, such as organic search, an engineered referral program, and a real local-search footprint, costs more patience up front and then compounds. The mix is the strategy. A budget document that shows one total number and no channel economics is a spending request, not a plan.
Then discount for the condition of the engine. This is the input boards skip most often. Spend converts to revenue at a rate set by the infrastructure it passes through: attribution, conversion paths, sales follow-up, referral capture. Money poured into a broken engine produces activity, not growth. The practical rule: the worse the instrumentation, the smaller the budget increase you can justify and the larger the share that should go to fixing the engine itself.
The reflex after close is to fund growth by adding spend. The record argues for skepticism. One of our engagements involved a PE-backed flooring retailer whose commercial engine was rebuilt end to end: diagnosis first, measurement second, then a deliberate shift of the mix toward owned channels. Revenue grew 36 percent over 24 months on essentially flat marketing spend. The growth was funded not by new money but by redirecting money that had been quietly producing nothing.
The same logic runs the other direction. A multi-site consumer services platform that shifted its mix toward owned acquisition cut customer acquisition cost by 60 percent while tripling the share of demand from owned channels. At that point the question "how much should we spend" had inverted into a better one: "how much of what we spend still needs to be spent at all." A budget conversation that never asks the second question is leaving the cheapest growth in the building unfunded.
None of this means budgets should shrink on principle. Underspending is a real failure mode, particularly for companies whose PE-backed competitors are consolidating a market and buying attention aggressively. The point is sequence: fix the measurement, prove the channel economics, then scale spend into what works. Spend scaled into an instrumented engine is an investment. Spend scaled into an uninstrumented one is a hope.
For a company early in a hold period, the sequence that produces a defensible budget looks like this. First, diagnose: a structured commercial audit, about eight weeks, establishes what actually drives revenue today, which channels carry what economics, and where spend is leaking. Second, instrument: build the single source of revenue truth and honest attribution, so that channel decisions run on the company's own data. Third, cost the plan: translate the deal model's revenue target into demand, and the demand into channel-by-channel spend. Fourth, sequence the mix: protect what works today, fund the owned assets that compound by exit, and put explicit payback expectations on every material line. Fifth, review against actuals at board cadence, and reallocate without sentiment.
Run that sequence and the percentage takes care of itself. The company might land at 4 percent of revenue or at 14, and either number is defensible because it is derived from the plan rather than borrowed from a survey. The percentage becomes a description of the answer, not the method for finding it.
A marketing budget survives board scrutiny when it is presented as an investment case with the same discipline as a capital project: expected revenue attached to spend, payback periods by channel, the owned-versus-bought mix and its trajectory, and named owners for every number. The reporting layer matters as much as the budget itself; a board that only ever sees spend and leads will manage marketing as a cost, while a board that sees channel economics and payback will manage it as an asset. We cover the reporting structure that makes this possible in the board-ready marketing reporting guide, and the wider first-year commercial agenda in the first-100-days plan.
One habit separates the strongest presentations: volunteering the failures. A budget review that shows two channels killed and the money moved reads as management in control of the engine. A review where every line is working reads as measurement too weak to catch the lines that are not. Boards know which one they are looking at.
Published benchmarks cluster between 5 and 12 percent of revenue, with services businesses toward the lower end and software toward the higher end. Treat that range as a sanity check, not an answer. The defensible budget is built from the value-creation plan: the revenue the deal model requires, the unit economics of the channels available, and the capacity of the current commercial engine to convert spend into customers. Two companies with identical revenue can justify budgets that differ by a factor of three.
Not automatically, and often not immediately. If the commercial engine is uninstrumented, adding spend scales the waste along with the growth. The higher-return first move is usually a diagnosis: establish what currently drives revenue, fix measurement and attribution, and then scale the channels that demonstrably work. Several of the strongest outcomes we have seen involved flat or reduced spend paired with a rebuilt engine rather than a bigger budget for the old one.
A board should evaluate the budget as an investment case, not a cost line: what revenue the spend is expected to produce, over what period, through which channels, measured how, and owned by whom. The productive questions are about payback period, the split between spend that builds owned assets and spend that rents attention, and whether the measurement behind the numbers would survive diligence. A percentage compared against an industry benchmark answers none of those questions.
Benchmarks describe what companies spend on average, not what any specific company should spend to hit its plan. They ignore the three things that actually determine the right number: the growth the deal model requires, the state of the company's commercial infrastructure, and the unit economics of its channels. A company with broken attribution and an unmeasured referral engine has no business spending to a benchmark, because it cannot yet tell which half of the budget is working.
There is no single defensible number, but the discipline matters more than the target: every material line of spend should carry an expected payback period, and the board should see actuals against it. Channels that build owned assets, such as a durable search presence or an engineered referral program, typically pay back slowly and then compound. Bought channels pay back quickly and stop the day spending stops. A hold-period budget needs both, sequenced deliberately, with the mix shifting toward owned assets as the exit approaches.
