How Much Should a Small Business Spend on Marketing?

We recommend building the amount from your business conditions and the work being proposed. The SBA's marketing-budget article says there is no fixed answer for every business.¹ That article is historical guidance, published in 2019, so we do not turn its percentage examples into a current benchmark or a recommendation for your business.

Start with the goal, available cash, capacity to serve customers and costs of a limited scope. Then agree on the evidence you will review before making a further commitment.

What should the budget pay for?

We suggest separating costs before comparing quotes. A service fee, advertising spend and a software subscription should not disappear inside one unexplained total. The SBA's marketing-plan guidance calls for a detailed budget and comparison of marketing costs with resulting revenue.²

Ask which of these categories applies to your proposed work:

Not every engagement needs every category. Ask the provider to identify what is necessary, optional and outside its quote. Record ongoing costs separately from setup so you can see what continues after the first deliverable is accepted.

How much can the business commit to a first scope?

We recommend checking the spending limit before assuming that marketing will pay for itself. Decide what you can commit using your actual cash position and other obligations. Do not fund a proposed test with revenue that has not occurred.

Also review operating capacity. What work do you want more of? Can the business deliver it, respond to inquiries and handle the approvals required by the proposed scope? If one of those conditions is unresolved, include it in the decision rather than treating marketing spend as the only constraint.

Write down what you need to learn from the first commitment. You might want to verify a contact route, understand inquiry sources, test a message or assess a proposed campaign. Choose a scope that answers the question you can currently investigate. Agree its cost limit and review window up front; neither should depend on a guaranteed result.

How can you connect spending to a customer target?

We suggest using a worksheet with your own inputs rather than a borrowed dollar example. Mark unknowns as "to confirm". If an input is uncertain, show how different values would change the calculation instead of selecting the most attractive value.

One planning calculation is:

Completed sales needed to cover the proposed cost = proposed marketing cost ÷ contribution per completed sale.

Use that expression only when the inputs have been defined and contribution is positive. It describes the arithmetic of covering the specified cost; it does not forecast sales, establish the time needed, or account for every expense in the business. If the result includes part of a sale, the whole-sale target would need to be rounded upward.

We recommend using the calculation as a question for the proposal: is the required work within our capacity, which assumptions need checking, and what evidence could show whether the activity contributed? Do not treat the answer as proof that the campaign will reach the target.

What should a small first test include?

We suggest agreeing on a question, deliverables, spending cap, responsibilities and review decision. State what the provider will do and what the business must supply. Specify who can approve additional spending; a test budget should not expand without an agreed decision.

Choose measures before work begins. If the immediate goal is to repair an inquiry path, completion may be checked through the approved change and successful testing. If the goal is to assess customer response, agree on how inquiries will be recorded and what qualifies as relevant to the business.

Record the review window and the information it might leave unresolved. A brief test can help you inspect execution without establishing the long-term economics of a channel. We recommend agreeing on what would justify continuing, changing scope or stopping. Those criteria should use available evidence rather than an expectation of a guaranteed return.

How should you review spending?

Compare what was spent with what was delivered and what you can observe. Separate service fees and other costs from the amount spent on media. Review inquiry quality, completed work and contribution where those records exist. The SBA recommends monitoring marketing costs against resulting revenue.²

We also recommend recording attribution limits. A customer might have encountered several touchpoints, and offline inquiries may be missing from an online report. Do not assume every sale during a campaign came from that campaign. Ask what tracking supports the connection and what remains uncertain.

Before increasing the budget, inspect operational dependencies as well as marketing activity. A broken contact route, incomplete information or delayed responses may warrant correction before more spending. Use the review to choose a specific next step, with a new cap and responsibilities if the scope changes.

We suggest keeping one record of budget approvals alongside the work plan. Include the approved expense, the person authorizing it and any condition that must be met before payment. This helps distinguish a proposed additional task from an expense you have already agreed to fund, especially when several suppliers or tools are involved.
