How Much Should a Small Business Spend on Advertising? (Marketing & Business QnA)

How much should a small business spend on advertising? Most profitable small businesses spend roughly 5% to 10% of revenue on marketing, with around 8% being a common benchmark (US Small Business Administration). But that percentage is just a starting point. The real answer: spend what you can afford every single month without it hurting you. Then let the numbers decide when to go bigger. If you know your conversion rate and your cost per sale, you can work backwards from a goal. R10,000 a month is a sensible, sustainable place for many SA small businesses to start, then scale what works. This is the V8 Media Marketing & Business QnA [18 Oct], written out with South African examples so you can act on it today.

This one started as a live Marketing & Business QnA.

Real owners, real questions, no script.

We got into ad budgets, knowing your numbers, e-commerce margins, breaking into new markets, and how to actually win Black Friday.

I have built V8 Media from nothing into an agency that has driven over R2 billion in client sales. The questions in this session come up in almost every strategy call we run.

Watch the full QnA below. This is the written version, with the benchmarks and the SA framing so you can use it.

How much should a small business spend on advertising?

This was the first question, and it is the one every owner wrings their hands over.

"Is it better to run a small amount over a long period, or a bigger amount over a shorter period?"

Two things decide it: your goal and your cash flow. There is no single magic number.

But there are benchmarks worth knowing. The US Small Business Administration says profitable businesses doing under $5 million a year spend about 7% to 8% of revenue on marketing.

Gartner's 2024 CMO Spend Survey backs the same ballpark. Across the firms it tracks, marketing budgets averaged 7.7% of revenue, down from 9.1% in 2023, and 11% in the four years before the pandemic.

The long-running CMO Survey, run by Christine Moorman with Deloitte and Duke, sits in the same band. Call it 5% to 10% of revenue.

Your stage moves that number. Pre-revenue or just launching tends to sit higher, around 10% to 20% of projected revenue. Growing businesses sit near 7% to 10%. Stable, mature ones drop to 4% to 7%.

Business stage	Marketing as % of revenue	Why
Just launching / pre-revenue	10% to 20%	You are buying data and a foothold. It costs more to be seen at first.
Growing	7% to 10%	You know what works. Now you pour fuel on it.
Stable / mature	4% to 7%	Brand and repeat customers carry more of the load.

Now translate that to Rands. A business turning over R1 million a year, spending 8%, is putting R80,000 a year into marketing. That is about R6,600 a month.

For local pricing, here is what we see running campaigns in the SA market. Meaningful social media advertising starts around R2,000 a month. Google Ads wants R2,000 to R5,000 to gather real data. A fuller digital marketing budget runs R8,000 to R25,000 a month.

So where do you start? My answer in the QnA was simple. Pick a number you can spend every single month without hurting the business. For a lot of SA small businesses, R10,000 a month is a sane, sustainable starting point. Then adjust based on what the numbers show.

Bottom line: start with what you can sustain, benchmark against 5% to 10% of revenue, and let performance decide when to scale.

Small budget over a long time, or a big budget over a short burst?

This is the part of the question most guides skip. The shape of your spend matters as much as the size.

It comes down to what you are selling.

If you are promoting an event, a webinar, or a launch with a deadline, a bigger spend over a short window makes sense. You want a spike of attention while it matters. Drip-feeding R100 a day at a webinar that happens next Tuesday is useless.

If you sell an evergreen product or service, something people can buy any day, a steady spend over a longer period wins. Consistency keeps the leads coming and gives the platform time to learn who buys.

	Short burst, bigger spend	Steady spend, longer run
Best for	Events, webinars, launches, time-limited offers	Evergreen products and services
Goal	A spike of attention before a deadline	Steady, predictable lead flow
Risk	Burns fast, then silence	Slower to feel, but compounds
Platform learning	Little time to optimise	Plenty of data to optimise on

Most small businesses I talk to are selling evergreen stuff. So steady usually beats spiky. We broke the budget maths down further in our guide on how to calculate the perfect Facebook ad budget.

Bottom line: match the shape of your spend to your offer. Deadlines want bursts. Evergreen wants consistency.

Know your numbers, or you are flying blind

This was the theme that ran through the whole QnA. Knowing your numbers.

One owner in the session said it perfectly. She needs 20 new clients a month. She spends about R10,000 on ads to get them.

Because she knows her conversion rate, she can work the whole thing backwards.

Here is the maths she was running. Say her landing page converts 1 in 10 leads into a client. To get 20 clients, she needs 200 leads. If R10,000 buys her 200 leads, her cost per lead is R50, and her cost per client is R500.

Now the questions get easy. Want 40 clients next month? You need about R20,000. Cost per lead creeping up? You spot it early and fix it before it eats the month.

That is the whole game. When you know your numbers, ad spend stops being a gamble and becomes a calculator.

When you do not know them, you are guessing. And guessing with your ad budget is how good businesses bleed out slowly.

Entrepreneurship is not just having a great idea. It is managing the boring business side well enough to keep the lights on. We listed the exact figures to watch in the most important numbers to track in your business.

Bottom line: know your conversion rate and cost per sale, and your ad budget becomes a simple sum instead of a guess.

E-commerce margins: the 150% to 200% markup rule

Then the chat turned to e-commerce. And the first thing I said was: check your margins before you do anything else.

Plenty of online stores look busy and still go broke. The reason is almost always thin margins.

My rule of thumb is a markup of at least 150% to 200% on cost. So a product that costs you R100 should sell for R250 to R300, minimum.

Why so much? Because the cost of the product is only the start. By the time the sale is done, a stack of other costs has taken a bite.

• Advertising. What you paid to get the customer in the door.
• Payment gateway fees. The slice the card processor takes on every order.
• Shipping and couriers. Often more than you budgeted, especially outside the metros.
• Software subscriptions. Your store platform, apps, email tool. They add up.
• Staff salaries. Someone has to pack, support, and run it.
• VAT. 15% in South Africa once you are registered. Plan for it from day one.

Strip all of that out of a 30% markup and there is nothing left. You are working for free, or worse.

This is why I bang on about profit over revenue. A R1 million store with no margin is a very expensive hobby. You end up with turnover that impresses people at the braai and a bank balance that does not. If you want the real picture, read how much profit the average e-commerce store actually makes.

Bottom line: aim for a 150% to 200% markup, because product cost is only one of at least six costs eating your sale.

Entering a new market vs competing in a saturated one

One owner was selling something genuinely new. A unique water filtration system. Great product, but nobody was searching for it.

That is a different game to selling something people already want.

There are really two roads here, and they need different marketing.

	Saturated market	Brand-new market
The customer	Already wants it and is shopping around	Does not know they need it yet
Your job	Stand out with a clear, unique selling point	Educate first, then sell
The cost	Higher competition, higher ad costs	More time and money spent teaching
The upside	Demand already exists, faster sales	Less competition once people get it

In a saturated market, you do not need to invent demand. You need a reason to be chosen. A sharper offer, better service, a clearer promise.

In a brand-new market, you are spending money to teach people they have a problem worth solving. That is slower and pricier, but the competition is thin once it clicks.

Both markets can win. But you have to know which one you are in. Get it wrong and you are running the wrong play with the wrong budget.

Bottom line: in a crowded market, sell your difference. In a new one, teach the problem first, then sell the fix.

Entrepreneur vs business owner: which one are you?

This one always sparks debate, and it did again.

People use "entrepreneur" and "business owner" like they mean the same thing. They do not.

An entrepreneur is the ideas person. Vision, innovation, new things, big bets.

A business owner is the operator. Finances, logistics, systems, making the thing actually run and scale.

	Entrepreneur	Business owner
Focus	Vision, ideas, innovation	Operations, finances, logistics
Energy	Starting and creating	Running and scaling
Risk	Loves the leap	Manages the landing
Danger if missing	A tidy business with no growth	A great idea that never makes money

Most of us start as both, by force. You have the idea and you also have to do the VAT.

The point is not to pick a lane forever. Know which one you are in right now, and make sure someone is covering the other one. Borrowed, hired, or partnered, it does not matter.

Brilliant ideas die every day because nobody wanted to do the boring part. And plenty of well-run businesses stall because nobody is dreaming up what is next. You need both seats filled.

Bottom line: entrepreneurs create, owners operate. Know which you are, and cover the gap with the right hire or partner.

How to actually win Black Friday

Black Friday was around the corner when we recorded this, so it came up. It always does.

Here is the mistake. Owners slap a lazy 10% off on everything and wonder why nothing moves.

Shoppers are not stupid. On Black Friday they expect a real deal. A token discount just makes you look like you are pretending to play.

So my advice was, and is, three things.

Offer a real deal. If you cannot afford a genuine discount, your margins are too thin (see the section above). Fix that first.

Use it to buy customers, not just sales. Black Friday is the cheapest time of year to win a new customer. Accept a slimmer margin on the first order if it brings someone into your world.

Play for lifetime value, not the day. The money is not in the one Black Friday order. It is in that customer buying again in January, March, and next November.

Think of the day as customer acquisition with a discount attached, not a one-off revenue grab. That single reframe changes how you price the whole event.

We went deeper on the trends and tactics in our Black Friday secrets and trends breakdown.

Bottom line: offer a real deal, use it to acquire customers cheaply, and win on lifetime value, not one day's revenue.

The one thread tying it all together: your numbers

Step back from all six questions and one thing connects them.

Numbers.

How much to spend on ads? A numbers question. What markup to set? Numbers. Whether Black Friday paid off? Numbers.

Your numbers are the health check on your business. Ignore them and you are running blind, hoping it works out.

I said it on the call and I will say it here. Ignoring your numbers is running a business with your eyes shut. You will hit something.

You do not need a finance degree. You need to know a handful of figures and check them often. Cost per lead. Cost per sale. Margin. Repeat purchase rate.

Get those in front of you weekly and most of these "hard" decisions answer themselves.

Bottom line: almost every business decision is a numbers decision in disguise. Know your figures and the fog clears.

How V8 Media helps you spend smarter

Knowing what to spend is easy. Spending it without wasting half of it on the wrong channels is where most small businesses come unstuck. That is what we fix.

We have worked with over 500 businesses and driven more than R2 billion in client sales, so we have seen what works and what quietly wastes money.

For most small businesses, the fastest route to revenue is a well-run paid channel feeding a tight follow-up system. We build that with Meta Ads to create demand, Google Ads to catch people already searching, and our AI lead generation system to make sure no lead slips through the cracks.

We do not guess with your budget. We track cost per lead and cost per sale, then scale the winners and cut the losers.

If you want the bigger picture first, start with the best small business marketing strategies, then come back and put a real number on your ad budget.

Frequently asked questions

How much should a small business spend on advertising?

Most profitable small businesses spend around 5% to 10% of revenue on marketing, with about 8% a common benchmark per the US Small Business Administration. Just-launched businesses often sit higher, near 10% to 20% of projected revenue, while mature ones drop to 4% to 7%. The percentage is only a guide. The better approach is to set a monthly number you can sustain without hurting cash flow, then scale it based on your cost per sale. For many South African small businesses, around R10,000 a month is a sensible, sustainable starting point.

Is it better to spend a small budget over a long time or a big budget quickly?

It depends on what you are selling. For events, webinars, launches, or time-limited offers, a bigger spend over a short window creates the spike of attention you need before the deadline. For evergreen products and services that people can buy any day, a steady spend over a longer period wins, because it keeps leads flowing and gives the ad platform time to learn who buys. Most small businesses sell evergreen offers, so consistent spend usually beats short bursts.

What profit margin should an e-commerce business aim for?

Aim for a markup of at least 150% to 200% on your product cost, so something that costs R100 sells for R250 to R300 or more. That cushion is not greed. Product cost is only one expense. You also have to cover advertising, payment gateway fees, shipping, software subscriptions, staff, and 15% VAT once registered. A thin markup like 30% leaves nothing once those are paid, which is how busy-looking stores still go broke.

How do I know how much to spend to hit my sales goal?

Work backwards from your numbers. If you want 20 new clients and your landing page converts 1 in 10 leads, you need 200 leads. If R10,000 buys 200 leads, your cost per lead is R50 and your cost per client is R500. Want to double to 40 clients? You need about R20,000. Once you know your conversion rate and cost per sale, your ad budget becomes a simple calculation instead of a guess.

How should a small business approach Black Friday?

Treat it as cheap customer acquisition, not a one-day revenue grab. Shoppers expect a genuine discount, so a token 10% off rarely works. Offer a real deal, accept a slimmer margin on the first order to win the customer, and play for lifetime value, because the profit is in that customer buying again through the year. If your margins are too thin to offer a real deal, fix your pricing before the sale, not during it.

What is the difference between an entrepreneur and a business owner?

An entrepreneur focuses on vision, ideas, and innovation, while a business owner focuses on operations, finances, logistics, and scaling. Most people start as both out of necessity. The key is to know which role you are in right now and make sure someone is covering the other one, you on a different day or the right hire. Great ideas die without operations, and well-run businesses stall without fresh vision, so you need both seats filled.
