How Much Should a Small Business Spend on Marketing?

August 25, 2026 · by AI Website Builder

Spend too little on marketing and a good business stays a secret; spend with no ceiling and the adverts quietly eat the profit. From what one customer is worth, you can set your own figure, split it between lasting foundations and timed tests, and see which channels pay. The AI Online Marketing Strategy Generator puts a suggested budget inside a 90-day plan, with the numbers to watch beside it.

Nobody sits down and chooses the marketing budget in a typical small business; it simply piles up. Some of it goes on flyers after a quiet month, some on a directory listing because the salesperson was persuasive, and some on promoted posts whenever a rival's advert catches the owner's eye. Added up at the end of the year, the total often comes as a surprise, and nobody can say what it bought. No single figure suits every business, and one borrowed from a neighbour or a large company says little about yours. There is, however, a sound way to reach the right amount for your own trade, and it begins with what one customer is worth to you over time. With that number roughly right, the rest is arithmetic: a monthly amount you can write down, a reason for choosing it and a way to judge whether it was well spent.

Why a rule of thumb is a poor place to start

Advice on marketing spend often arrives as a fixed share of turnover, borrowed from large companies whose situation looks nothing like yours. A new business with no customers yet needs to spend more, relative to its income, than one that has run happily on referrals for ten years. A business with healthy margins, such as a physiotherapy practice, can afford to pay more to win each client than a corner shop selling groceries on thin margins. A firm whose customers return every month can spend more on winning each one than a firm whose customers buy once in a lifetime, such as a wedding dress maker. Copying another business's figure ignores every one of these differences. That is why the better starting point is your own numbers, however rough they are.

It also helps to know what your marketing will involve before you put a price on it. Channels come first and the budget follows them, a sequence set out in our guide on how to draw up a marketing plan for a small business. To see what a realistic plan looks like for your trade and area, you can get a marketing plan built on real searches from our free strategy tool, with your channels in order, content ideas and a suggested budget for the next ninety days. A budget with a plan behind it is much easier to defend, both to yourself and to anyone you share the business with. Without one, every advertising seller who rings sounds as convincing as the last. With one, you can thank them politely and point to the money already allocated.

Work out what a customer is worth to you

The most useful number for setting a budget is what a typical new customer is worth over the whole time they stay with you. Picture a car service garage in Johannesburg where the average visit brings in around 1,800 rand and a typical customer comes back twice a year for about three years. That customer is worth roughly 10,800 rand in sales across those three years, not the 1,800 rand of the first visit. After parts and wages, suppose about a third of that is profit, leaving roughly 3,600 rand for each loyal customer the garage wins. Seen that way, spending a few hundred rand to win a customer who stays is an excellent trade. Spending more than 3,600 rand to win one would lose money, however busy the workshop looked.

Work out the same figure for your own business, even if you have to estimate parts of it. Use your records, or your memory if records are thin, for how much a typical customer spends each time, how often they return and for how long. Then think about what is left after the direct costs of serving them, such as materials, stock or staff hours. A dog groomer in Austin, a wholesale egg supplier in Ibadan and a freelance designer in Manila will reach very different answers, and that is exactly the point. Write the figure somewhere you will see it, because it becomes the ceiling on what you can pay to win a customer. Spending below that ceiling is an investment that pays back, while spending above it is a loss, however lively it makes the business feel.

The ceiling is not the target, though, because estimates are often hopeful and some marketing simply fails. A sensible target is a fraction of the ceiling, perhaps a quarter or a third, so that each new customer still leaves the business clearly better off even when your guesses prove generous. For the garage, that might mean being willing to spend up to about 1,000 rand to win each regular customer. This figure, your acceptable cost per customer, is what turns budgeting from guesswork into arithmetic. Once you know it, you can compare any channel or offer by asking what it would cost to win one customer that way. A newspaper advert, a promoted post and a stall at a trade fair suddenly become comparable on the same scale.

Turning goals into a small business marketing budget

With an acceptable cost per customer in hand, setting the budget becomes simple multiplication. Decide how many new customers you need each month to reach your goals, then multiply that number by your target cost. A yoga studio in Bristol that wants twelve new members a month and is happy to spend about forty pounds to win each one has a starting budget of roughly 480 pounds a month. A bookkeeping practice in Nairobi that needs only two new clients a month, each worth a great deal over the years, might set aside 20,000 shillings, spent mostly on being found by people searching for bookkeeping help. Neither figure comes from a rule, since both come from goals and the value of a customer. If the result is more than the business can afford, lower the goal for now rather than pretending a smaller sum will achieve the same.

A brand new business has a harder job, because it has no history to estimate from. In that case, base the budget on what you can afford to lose without harming the business, and treat the first three months as a way of buying information. A new phone repair stall in Kampala might set aside a modest sum each month for flyers, a few promoted posts and a bright sign, then record exactly how many customers each one brings. After a quarter it will have real numbers to replace its guesses. Expect the cost of each customer to be higher at first, while nobody knows your name and you are still learning which messages land. That early cost tends to fall as reviews build up and past customers begin to recommend you.

Budgets also need to follow the shape of your year. A school uniform supplier in Harare does most of its trade in the weeks before each term, so spending evenly across twelve months would waste money in the quiet weeks and starve the busy ones. A tax adviser sees the opposite pattern, with enquiries bunching up before filing deadlines and almost vanishing straight afterwards. Look back at when your enquiries usually arrive and plan to spend more in the weeks just before those peaks, when people are starting to search. Keep a small amount running in the quiet months so that you never disappear entirely. The total for the year can stay the same while the monthly figure rises and falls with demand.

What the money and your time actually go on

Part of every marketing budget is fixed, and it should be paid first because everything else depends on it. That usually means your website, your domain, a professional email address, good photographs of your work and whatever you hand to customers, such as business cards or a price list. AI Web Maker charges nothing while you build and preview your site and $119 a year for hosting once it goes live, with the domain as a separate cost, so the foundation is a known and modest figure. Your Google Business Profile costs nothing to set up and keep current, yet for many local businesses it is one of the main ways new customers find them. These foundations keep working month after month without fresh spending, which is why they come before anything else. If they are weak, every advert you pay for drives people towards a shop window that puts them off.

The rest of the budget is variable, and this is where testing matters most. Paid adverts on Google or social media, sponsored posts, local radio, printed flyers, event stalls and paid directory listings all belong here. Treat each one as an experiment with a spending limit, a time frame and a way to count results. A florist in Pretoria might give promoted posts on Facebook a fixed amount for the month before Valentine's Day, with a simple code customers mention when ordering so she can tell which orders the posts brought. If the cost per customer comes in under her target she can spend more next time, and if it does not she has learned something useful for a small, known price. Never let a variable channel run without an end date, because forgotten adverts are an easy way for small budgets to leak away.

Your own time belongs in the budget too, even though it never appears on a bank statement. An owner who spends six hours a week on social media is spending something real, and it is fair to ask what else those hours could produce. For a hairdresser in Glasgow, six hours might mean six paid appointments, while for a consultant it might mean a full day of billable work. That does not mean you should stop doing your own marketing, since the owner's voice is often the most convincing one a small business has. It does mean comparing the value of your hours with the cost of paying someone for specific jobs, such as editing photographs or setting up adverts. Sometimes the cheaper option is to pay, and sometimes it is to keep doing the work yourself in fewer, better organised hours.

If the honest answer is that you have almost nothing to spend, do not wait until you do. A tiny budget changes the mix rather than the method, so you lean on the work that costs time instead of money, such as asking every happy customer for a review, partnering with neighbouring businesses and answering common questions on your website. A tailor in Lusaka could agree with a nearby bridal shop to recommend each other, which costs nothing more than a conversation and a stack of business cards on each counter. Keep counting where customers come from, because your first small profits should go to whichever channel proves itself. As the business grows, the same arithmetic will tell you how much more you can sensibly spend. Starting small is no weakness, as long as every coin is accounted for.

Checking whether the money is well spent

A budget only becomes useful once you check what it bought. The most valuable habit is one question put to every new customer about where they first heard of you, with the answer noted in a book by the till or a column in a spreadsheet. At the end of each month, add up what you spent on each channel and divide it by the customers that channel brought, which gives you a rough cost per customer. Compare that with the target you set earlier. Channels that come in comfortably under the target deserve more money next month, and channels that come in well over it deserve a hard look. Over a few months this plain routine shows you where money works hardest for your particular business.

Some of the most valuable marketing costs time rather than money, so give those jobs a share of your budget in hours. Improving your website so that it appears for the searches your customers use, collecting reviews and keeping your Google Business Profile current all bring customers at a low cost once the work is done. Our AI SEO Tools are free and help with exactly these jobs, from the AI Website SEO Checker, which shows what is holding your pages back, to the Keyword Difficulty Checker, which tells you which searches are realistic targets. Because these channels keep bringing enquiries long after the work is finished, their cost per customer tends to fall over time, unlike adverts, which stop the moment you stop paying. A balanced budget usually combines both, with steady work on being found plus paid channels used for specific goals and seasons. That mix is how a modest budget earns more than its size would suggest.

So how much should you spend? Enough to win the customers your goals require, at a cost per customer comfortably below what each one is worth to you, and no more than you could stand to lose while you are still learning. Start by working out the value of a customer, set a target cost, multiply by the number of customers you need and adjust for the seasons of your trade. Pay for the foundations first, test everything else with limits and end dates, and count your own hours honestly. Then check the numbers every month and move money towards whatever works. A modest budget that is planned and measured will nearly always outperform a larger one spent on impulse.
