Every founder eventually asks the question, and every answer they find is a different number, should it be 5% of revenue?
No, 10%.
No, 12%, if you’re growing.
The truth nobody selling marketing wants to lead with is that the percentage question is mostly the wrong question. Benchmarks are averages of strangers, companies with different margins, different customer values, different competition, different leaks. Copying their average is like taking a stranger’s prescription because you’re both roughly the same height.
This guide gives you something better: the way to derive your number, and, more important than the total, the order to allocate it in.
What the benchmarks actually say (and why to hold them loosely)
Commonly cited guidance puts small-business marketing spend somewhere between 5% and 10% of revenue, lower for established businesses defending a position, higher for businesses in growth mode or launching, higher again for consumer businesses than industrial ones.
Your ₦1M+ monthly spend, against typical Nigerian SME revenues, likely sits inside or near that band already.
But note what the benchmark can’t tell you: whether your spend is working.
A business spending 4% of revenue on a sealed, measured system will outgrow one spending 12% into leaks.
The total is the least interesting number in your marketing budget. The allocation is everything.
The grown-up method: derive the number from unit economics
The businesses that budget marketing confidently all use some version of the same logic, and it has three steps:
- Know what a customer is worth. Not one purchase, the profit a customer generates over their time with you (their lifetime value). If you haven’t calculated this, it’s the prerequisite; we’ve written a full guide to customer worth in naira.
- Decide what you’ll pay to win one. A common, defensible position: acquiring a customer should cost no more than a third of what they’re worth, so the relationship is comfortably profitable after service costs and surprises. That ratio is a starting posture, not a law, a business with fast repeat purchases can afford more aggression than one with slow, single sales.
- Multiply by the growth you want. Want 50 new customers a month, at an affordable acquisition cost of ₦40,000? Your acquisition budget wants to be about ₦2M, plus the fixed costs of the system that makes acquisition work. Now the budget is a consequence of a growth decision, not a guess dressed as a percentage.
Notice what this method does: it converts “how much should we spend?” into “how many customers do we want, and what can we afford to pay for each?”, questions your business can actually answer, and questions that make every naira accountable to a target.
Budget the four walls in order
Here’s where most budgets fail, and it’s not the total, it’s that nearly everything goes to visible spending (ads, content, posting) while the infrastructure that makes visible spending work goes unfunded. In our complete guide to the marketing maze we make the full argument for the build order; here is what it means for a budget, concretely:
- Fund measurement first, permanently. A modest, non-negotiable slice, often 5-10% of the total, for tracking infrastructure, reconciliation, and reporting. This is the line that makes every other line auditable. Skipping it to buy more ads is how businesses spend confidently on fiction; the measurement piece shows what that costs.
- Fund conversion before more traffic. If your pages leak, the highest-return line in the budget is fixing the destination, because a conversion improvement multiplies the value of every visitor you already buy. Only then does scaling traffic make arithmetic sense.
- Fund retention as an asset, not an afterthought. Email and WhatsApp programmes cost little relative to acquisition and compound, they’re the lines that make this year’s acquisition spend keep paying next year.
- Then scale acquisition aggressively, into a system built to keep what it catches, with rising auction prices making the sealed-system requirement stricter every year.
The most common Nigerian marketing budget we audit is 90-100% acquisition, 0% measurement, 0% conversion, 0% retention. It isn’t a small budget that fails. It’s a lopsided one.
Three budget rules that survive contact with reality
Set a floor, not just a ceiling
Budgets get discussed as maximums, but the more dangerous number is the minimum. Below a certain spend, channels don’t produce weaker results, they produce no signal at all: too little data to optimise ads, too little content to build visibility, too little consistency to compound. If a channel can’t be funded to its minimum effective dose, the honest move is not to fund it thinly, it’s to not fund it yet, and concentrate.
Separate testing money from proven money
Hold a small slice, commonly around 10-15%, for deliberate experiments: a new channel, a new offer, a new audience. Everything else goes to what’s already proven, at pace. This keeps innovation alive without letting hope raid the budget that pays the bills, and it gives every experiment a defined cost and a written goal instead of an open tab.
Review allocation quarterly; commit monthly
Channel economics shift, auctions inflate, algorithms turn, seasons change. The budget that was right in January is stale by June. A quarterly reallocation against reconciled revenue data (not platform-claimed numbers) keeps money flowing toward what’s actually working. Monthly commitment keeps you from the equal and opposite error: whipsawing spend around before anything has had time to work.
Budgeting done right
There is no magic percentage, and anyone leading with one is selling simplicity, not strategy. The durable answers: derive the total from what a customer is worth and how many you want; allocate it in the order that seals the system before scaling the spend; set floors as well as ceilings; protect a testing slice; and re-decide quarterly on numbers you trust. A budget built this way has a property no benchmark can give you, every line in it can be held to a written goal, which means every line can be defended, fixed, or cut with confidence.
Want your budget pressure-tested? Our free marketing plan includes exactly this: your current allocation against the four walls, where the money is leaking, and a 90-day reallocation with a written goal on every line. If you’re spending ₦1M+ a month on marketing, it’s yours at no cost.
