How much does marketing cost for a small business?

The percentage of revenue rule, and its limits

The common benchmark is that established small businesses spend somewhere between five and ten per cent of revenue on marketing, and that businesses chasing growth or entering a new market spend more, often ten to twenty per cent.

Treat that as a sanity check rather than a formula. A business turning over £500,000 with long, high value contracts and three good referral partners may sensibly spend two per cent. A consumer brand fighting for attention in a crowded category can spend fifteen and still be under invested.

The percentage is most useful in reverse. Work out what you need marketing to produce, price the activity that would produce it, then check the total against your revenue. If the number lands at thirty per cent, the plan is too ambitious for the business as it is today.

Start from the target, not the spare cash

Budgets set from whatever is left at the end of the month get cut first and produce nothing. Budgets set from a target survive.

The working backwards version looks like this:

• How much new revenue do you need from marketing in the next twelve months?
• What is your average order or contract value, so how many new customers is that?
• What proportion of enquiries convert, so how many enquiries do you need?
• What has an enquiry cost you historically, across all channels?
• Multiply it out, then add the fixed costs that support all of it: website, tools, design, photography

If you have never tracked cost per enquiry, that is the first thing worth fixing. Without it, every budget conversation is guesswork dressed up as a plan.

How to split the budget once you have set it

A rough starting split for an SME is around half on activity that generates demand now, a quarter on the assets and content that make that activity work, and a quarter held for the foundations: website, tools, tracking and a contingency for the thing nobody predicted.

Two lines people forget. Tools and subscriptions quietly add up, and email, scheduling, CRM and design software can easily reach a few hundred pounds a month. And someone has to do the work, so if that is a person rather than a platform, their time is part of the cost even when it does not appear on a marketing invoice.

Agency, freelance or in house: what each costs

Most small businesses eventually compare three routes, and the honest answer is that the right one depends on how much work there is and how much direction you already have.

A full service agency retainer for an SME typically starts around £1,500 to £3,000 a month and rises quickly with channels and paid media management. You get a team and capacity, though junior delivery is common at the lower end.

A freelance or independent consultant is usually bought by the day, commonly £300 to £700 depending on whether the work is delivery or senior strategy. You get seniority without headcount, but you get one person, so capacity is finite.

An in house marketing executive costs roughly £28,000 to £38,000 in salary, and a marketing manager £40,000 to £55,000, before national insurance, pension, recruitment and software. Realistically add twenty to thirty per cent to any salary before comparing it with a monthly fee.

The mistake is comparing an agency retainer with a salary and stopping there. Compare what each one is accountable for. A junior in house hire needs direction from somewhere, and if nobody is giving it, the salary buys activity rather than results.

Three worked examples

At around £1,000 a month, buy focus. One channel done properly, a monthly email, and content that answers the questions your buyers actually ask. Expect the returns to build over months rather than weeks, and resist spreading it across four platforms.

At around £3,000 a month, you can run a proper mix: organic content and social, an email programme, a modest paid budget, and someone senior involved a day or two a month to keep it pointed at the right target. This is where most growing SMEs sit.

At around £5,000 a month, add paid media at a level that can be optimised rather than merely switched on, better creative and photography, and consistent senior oversight. At this level the reporting should be commercial: pipeline and revenue, not impressions.

What makes marketing cost more than it should

The usual culprits, in rough order of expense:

• No plan, so spend is reactive and nothing compounds
• Too many channels for the resource available, so all of them underperform
• Broken or absent tracking, so nobody can tell which spend to stop
• Rebuilding the same assets repeatedly because tone of voice and templates were never agreed
• Paying for delivery when the actual gap is direction

Fixing the last one is usually the cheapest intervention available. A clear plan makes a smaller budget work harder than a bigger budget spread thin.

A sensible first step if you are unsure

If you cannot currently say which activity produced your last ten enquiries, start there rather than with a budget. An audit tells you what is working before you commit money to more of it, and it is a considerably cheaper way to find out than a year of retainer.

Once the direction is clear, the budget question gets much easier, because you are pricing a specific plan rather than guessing at a percentage.
