How Much Should You Spend on Marketing?

The common rule of thumb is 5–10% of revenue for established businesses and 10–20%+ for those in a growth push or launching something new — with B2B typically at the lower end and B2C/e-commerce higher. It's a fine starting sanity-check. But a percentage of revenue is a backward-looking anchor, and the better budget is built forward from what you're trying to achieve.

Why the percentage rule is only a starting point

A revenue percentage tells you what similar companies spend, not what your goal requires. Two businesses at the same revenue can need wildly different budgets depending on growth targets, margins, sales-cycle length, and how much of their growth comes from paid vs. organic. Use the rule to catch when you're wildly over- or under-invested — then set the real number a different way.

Build the budget from the goal

Work backward from a revenue or customer target:

• Start with the goal: how many new customers or how much new revenue do you need?
• Divide by conversion economics: using your customer acquisition cost (CAC) — or a forecast of it — the target customer count implies the spend required.
• Sanity-check against margin and payback: can you afford that CAC given your margin and how long it takes a customer to pay back? If the math doesn't clear, the goal or the channel mix has to change — not just the budget.

This is the difference between "we spend 8% because that's normal" and "we need 400 customers at a $120 CAC, so the budget is ~$48K — here's how it's allocated."

Split it: demand capture vs. demand creation

However you land on the total, divide it between capturing existing demand (branded search, retargeting, bottom-funnel — cheap, finite) and creating new demand (prospecting, content, upper-funnel — pricier, but the only way to grow beyond the people already looking). Businesses that pour everything into capture plateau the moment they've harvested existing demand.

Don't forget the non-media costs

"Marketing budget" isn't just ad spend. Tools, creative production, and people are part of the number — a budget that funds media but not the creative to fill it starves itself. Account for the whole system.

Set a total that your goal justifies, pressure-test it against your CAC and margins, split it across capture and creation, and put it in a plan you actually track against — that beats any one-size-fits-all percentage.
