How Much Should a Small Business Spend on Social Media Ads?

There is no correct ad budget that fits every business, and generic figures like “spend X% of revenue” ignore what matters: how much a customer is worth to you. Here is a way to set a budget from your own numbers.

Step 1: Know what a customer is worth

Work out, roughly:

• your average order value,
• your profit margin on that order,
• how often a customer buys again.

Profit per order multiplied by the number of orders a typical customer makes gives a rough customer value. That is the most you could spend to win a customer and still break even. Aim to spend well below it.

Step 2: Set a test budget

Start with a budget you can afford to spend while learning, for a fixed period such as two to four weeks. The goal of the first test is not profit; it is learning:

• which audience responds,
• which message and image work,
• what one enquiry or sale actually costs you.

Ad platforms need enough results to optimise. A tiny budget spread over many ads and audiences rarely teaches you anything. Test a few variations, not dozens.

Step 3: Measure the right thing

Likes and reach are cheap. What matters is the cost of the action that earns money: an enquiry, a booking, a purchase. To measure that, you need tracking set up properly.

Step 4: Scale what works, gradually

When a campaign brings customers below your target cost, increase the budget step by step rather than doubling it overnight. Sudden large changes can reset the platform’s learning and make results unstable.

Step 5: Keep some budget for retargeting

People who visited your site or engaged with your posts are more likely to buy. A small share of the budget aimed at them often brings the cheapest results.
