Marketing Budget Calculator

What percentage of revenue should go to marketing?

Between 3% and 15% of revenue for most businesses, and the spread inside that range matters far more than the midpoint. The honest answer is that there are four different benchmarks that could apply to you and they disagree, which is why the calculator shows all four rather than picking one for you.

The gap between that first row and the second is the most useful number on this page. The same survey reports a mean of 9.35% and a median of 3%. That is not a contradiction, it is a small number of very heavy spenders dragging the average up. If you are a small business comparing yourself to the average, you are comparing yourself to companies nothing like you. Forrester make the same point about their own 8% figure: do not plan a budget off a mean.

How much should a small business spend on marketing?

Companies under $10M in revenue report 11.4% of revenue in The CMO Survey Spring 2025, which is well above the all company median of 3%. Both are true. Smaller firms that answer marketing surveys tend to be the ones investing in marketing. The practical read is that anywhere from 5% to 12% is defensible for a small business, and where you sit inside that depends far more on whether you are trying to grow or trying to hold position than on your industry.

How much should a startup spend on marketing?

Ten to twenty percent of projected revenue while you are building awareness, falling to 7 to 10% once you are growing and 4 to 7% once you are mature. The word that matters in that sentence is projected. Early stage companies budget against the revenue they are trying to create, not the revenue they made last year, which is exactly why a percentage lifted from a mature company’s plan reads as reckless when a startup uses it.

Does industry change the answer?

Substantially. Consumer packaged goods reports 18.09% of revenue and energy 3.21%, a difference of nearly six times. The benchmarks tab carries the full fifteen industry table. Read your own row, and if your business sits between two rows, take the lower one and earn the right to the higher one.

How do you calculate a marketing budget?

Two ways, and a serious plan does both. The percentage method tells you what is normal. The goal method tells you what your own target costs. Where they disagree is where the conversation with your board or your client actually needs to happen.

Top down: marketing budget = annual revenue x target percent
Bottom up: customers needed = revenue goal / revenue per customer
           leads needed     = customers / lead to customer rate
           media budget     = leads x cost per lead

A worked example. You want 600,000 of new revenue, your average customer is worth 4,200 in year one, and you close 18% of leads. That is 143 customers and 794 leads. At a 110 cost per lead that is 87,340 of media. Media is about 30.6% of a full marketing budget, so the fully loaded figure is roughly 285,000. If your revenue is 2,000,000, that is 14.3% of revenue, well above the 9% benchmark for B2B services. Either the goal comes down, the close rate goes up, the customer gets more valuable, or the budget goes up. Those are the only four levers and the plan has to name one.

What is the difference between top down and bottom up budgeting?

Top down starts with what the business can afford and divides it up. Bottom up starts with the outcome you want and adds up what it costs. Top down is easy to get approved and easy to miss targets with. Bottom up is harder to get approved and much harder to argue with, because every number in it belongs to the business rather than to a survey.

Should I use gross or net revenue, and last year’s or next year’s?

Gross revenue, because that is what every benchmark on this page is calculated against. Using net revenue will make your spend look far higher than it is compared with the tables. On timing: trailing revenue if you are stable, projected revenue if you are early stage or growing fast. If you use projected revenue, write the projection down, because a budget built on a revenue forecast that nobody revisits is how marketing ends up overspent by Q3.

How accurate is a marketing budget calculator?

Accurate enough to start an argument with the right facts in it. The percentage side is only as good as how close your business is to the companies in the survey, and the goal side is only as good as your close rate. The one thing this calculator does that most do not is show you both numbers and the gap between them, which is where the useful information actually lives.

What does a marketing budget include?

Everything you would stop paying for if you stopped doing marketing, which is far more than advertising. This is the single most common reason a budget conversation goes wrong: one side means media spend and the other means the whole function.

Gartner’s 2025 CMO Spend Survey puts paid media at 30.6% of the marketing budget, which is roughly 2.4% of company revenue. So for a company spending 8% of revenue on marketing, under a third of that is buying ads. The SBA makes the same point from the other direction, citing data showing the average business spends only about 1.08% of revenue on advertising against 7.9% on marketing overall.

The newest line on the list is AI. Gartner’s 2026 survey reports 15.3% of marketing budgets now allocated to AI, rising to 21.3% at organisations that describe themselves as AI ready. That money comes out of the same pot, so it is worth deciding what it is displacing rather than discovering later.

How should I allocate a marketing budget across channels?

Start with whether you are capturing demand that already exists or creating demand that does not. Everything else follows from that, and no percentage table can answer it for you.

Demand capture means people are already searching for what you sell. Paid search, shopping, SEO and review platforms get the money because the intent is already there. Demand creation means they are not searching yet, so paid social, video, content, PR and events carry the weight and the payback is slower. Most businesses do both, and the mistake is funding them from one pot and judging them by one metric.

What is the 70 / 20 / 10 rule?

Seventy percent into channels that are proven to work, twenty into channels you are actively scaling, ten into things that will probably fail. It splits the budget by confidence rather than by channel, and its real purpose is procedural: it protects the experimental ten percent from being the first thing cut when a quarter looks tight. That is usually its whole value, because the ten percent is where next year’s seventy comes from.

How small is too small for paid search?

Roughly ten clicks a day is the floor for learning anything within a quarter. At the all industry average cost per click of $5.42 that is about $1,650 a month; for attorneys and legal services at $9.87 it is about $3,000; for arts and entertainment at $1.63 it is closer to $500. The calculator runs this check automatically against your industry and flags it when the paid search slice cannot support a real test. Below that line you are better off concentrating the budget on a narrow keyword set and a single geography, or leaving search out of the plan until the budget grows. Once the number clears, take the monthly figure into the Google Ads budget calculator to turn it into a daily budget and a lead forecast.

How often should I review the budget?

Set it annually, review it quarterly, and reallocate monthly inside the channels. Annual because that is how the business plans, quarterly because that is roughly how long it takes to know whether something is working, and monthly inside channels because moving budget from a losing campaign to a winning one does not require anyone’s approval and is usually the highest return decision available in any given month.

What if I am already spending more than the calculator suggests?

Then check the return before you check the benchmark. A company spending 18% of revenue on marketing with a 4 to 1 LTV to CAC ratio and an eleven month payback is not overspending, it is investing. A company spending 5% with no attribution and no idea what a customer costs is not being disciplined, it is being uninformed.

The order of questions that actually matters:

1. What does a customer cost you to acquire, fully loaded? The CAC calculator will give you both the paid and blended figures.
2. What is that customer worth in gross margin over their first year?
3. How long until the acquisition cost is paid back?
4. Only then: how does the total compare to what companies like you spend?

Benchmarks are for sanity checking and for board conversations. They are not a target, and hitting the industry average is not an achievement if the money is not returning anything.

How do I justify the budget to leadership?

Lead with the goal, not the percentage. Show what the revenue target requires in customers and leads, show the cost of those leads from your own data, and show the resulting budget. Then show the benchmark as a supporting slide rather than as the argument. A budget defended as “the industry average is 9%” invites the response “can we do it for 6%”. A budget defended as “the 600,000 target needs 794 leads and our leads cost 110” invites a conversation about the target instead, which is the conversation worth having.

Where a figure is an average, this page says so, and where the median tells a very different story it shows both. Survey benchmarks come from small samples inside each band, describe the companies who chose to answer, and change year to year, so treat every number here as a sanity check on your own plan rather than as a target to hit.
