How Much Should a Business Spend on Marketing?

The percentage-of-revenue rule of thumb

• Established businesses: often ~5–10% of revenue.
• Growth-focused or younger businesses: commonly 10–20%, investing to capture share.
• Highly competitive or new categories: can go higher still to establish a presence.

Treat these as a sanity check, not a target. They vary hugely by industry, margin and stage.

The better answer: unit economics

The percentage rule ignores the number that actually matters: what a customer is worth to you (their lifetime value) versus what it costs to acquire one (CAC). If you earn far more from a customer than it costs to win them, you should arguably spend more, not less, you’re buying profit. If acquisition costs more than a customer returns, no percentage is ‘safe’. Marketing budget is an output of your economics, not a fixed slice. This is core to our analytics work.

How to size and split the budget

1. Start from goals and economics — how many customers you need and what one is worth.
2. Split by horizon — some to channels that pay back now (ads), some to compounding assets (SEO, content, brand).
3. Protect the compounding spend — don’t cut SEO and brand first when budgets tighten.
4. Review against return — move budget to what proves out.

What most businesses get wrong

The biggest mistake is treating marketing spend as a fixed cost to minimise rather than an investment sized to return, so they cap it at a percentage even when every rupee is profitable. The second is spending only on channels that pay back this month (ads) and nothing on the compounding ones (SEO, content, brand), so growth never gets cheaper. The third is not knowing their CAC or customer value at all, which makes any budget a guess.

The contrarian take: the right number might be ‘as much as you can profitably’

Everyone wants a tidy percentage, but if your economics are healthy, the ceiling on marketing spend isn’t a rule of thumb; it’s how much profitable demand you can capture. A business that can acquire a ₹50,000-value customer for ₹5,000 shouldn’t stop at ‘10% of revenue’; it should spend into that gap until it closes. The percentage rule protects businesses that don’t know their numbers; businesses that do should let the math, not the benchmark, set the budget.

What tends to improve, a realistic picture

• Business type: a business unsure how much to budget for marketing.
• Common problem: capping spend at a percentage without knowing CAC or customer value.
• Typical approach: size the budget from economics and goals, split by payback horizon, protect compounding spend, review to return.
• What tends to improve: spend that follows profit, not a fixed slice. Outcomes vary with margin and market.

Marketing-budget check

1. Do you know your cost to acquire a customer and what one is worth?
2. Is your budget sized to return, or capped at a percentage?
3. Is spend split between quick-payback and compounding channels?
4. Is compounding spend (SEO, brand) protected when budgets tighten?
5. Do you move budget to what actually proves out?

Sized to your economics, marketing becomes an investment, not a cost. See our AI & Data Analytics and digital marketing.

The percentage-of-revenue rule and why it misleads

Everybody eventually reaches for a percentage of revenue. It is a reasonable sanity check and a poor planning tool, and the difference matters.

The rule assumes your situation is average, which it is not, and it points backwards at revenue you have already earned rather than forwards at the revenue you are trying to earn. A business with high margins and a long customer lifetime can justify spending far more per customer than a thin-margin business selling something people buy once, and applying the same percentage to both produces one company that is starving its growth and another that is burning cash on customers who will never pay it back. Stage distorts it further. A company opening a new location, or entering a city where nobody knows the name, has a legitimate reason to spend at a level that looks alarming against its current revenue, precisely because current revenue reflects a market it has not entered yet.

Use the percentage as a rear-view mirror. If you are wildly outside what similar businesses spend, that is worth explaining to yourself. It is not worth obeying.

Competitive pressure warps it further. If a well-funded rival enters your market and starts buying attention aggressively, holding your percentage steady means losing share while your spreadsheet says everything is on plan, and by the time revenue reflects the loss the gap is expensive to close. The reverse applies too, since a category where nobody is competing hard is one where a modest spend goes unusually far and matching a benchmark would simply be wasting money. Look outward before you look at the ratio. The ratio does not know who you are up against.

Budgeting by what you are actually short of

A more useful method starts with the constraint. Every business is short of one thing at a time, and the budget should follow it.

If nobody knows you exist, the constraint is awareness and the money goes to reach. If people find you but do not enquire, the constraint sits on the site and in the offer, so spending more on traffic simply buys more of the same disappointment at a higher price. If enquiries arrive and do not convert, the problem is in sales and follow-up, and no marketing budget fixes a lead that waits two days for a reply. If customers convert and never return, the constraint is retention, which is usually the cheapest thing to fix and the last thing anybody funds. Diagnose first. Fund second.

This also gives you a defensible way to argue for a number internally, since ‘we need this much because our conversion rate is the bottleneck and here is what we intend to change’ survives a finance conversation in a way that a benchmark percentage never does. It gives you something to measure against too. You said what you were fixing, so in ninety days everyone can see whether it moved.

Separate the money that keeps things running from the money meant to grow them. Maintenance covers the site, the listings, the existing campaigns and the basic content hygiene that stops your current position eroding, and cutting it feels efficient while quietly costing you ground. Growth money is the part making a bet on something new. Mixing them in a single figure means the growth budget gets eaten by maintenance every time a month is tight, which is how companies spend steadily for years and end up exactly where they started.

Changing the plan mid-year without losing the thread

Annual budgets get set once and then defended for twelve months, which is how money stays in a channel long after it stopped working. Build the review in from the start.

Split the budget into a part that runs continuously and a part you deliberately hold back, then review the held-back portion quarterly against what the continuous spend has taught you. The continuous part covers the things that only work with consistency, and search visibility, content and retention all belong there because stopping and restarting them destroys most of the value already paid for. The flexible part goes wherever the evidence points that quarter, which might be a channel that surprised you, a campaign that needs more room, or a competitor situation nobody predicted in January.

One discipline makes this work. Write down, before the quarter starts, what you expect each line to produce, then read it back at the end, because without that note every result becomes explicable after the fact and nothing ever gets cut. Kill the things that missed. Fund the things that did not.

Be careful about what cannot be restarted cheaply, though. Some spend can be stopped and resumed with no lasting damage, and paid media is largely in that category since the auction will still be there when you return. Other spend cannot. Content momentum, search visibility and a community that has grown used to hearing from you all decay when abandoned, and rebuilding them costs considerably more than maintaining them would have. Cut the reversible things first. Protect the compounding ones, even in a bad quarter, because those are the lines that were quietly doing the work the whole time.
