How much do Facebook and Instagram ads cost, and how do you set a budget?

To The Sky ·

Facebook and Instagram ads have no fixed price: costs depend on auction competition, your audience, the ad itself, and the result you want. The right budget starts with what you can afford to pay for a customer, then tests that assumption within clear spending limits.

How the auction and your audience affect cost

Meta, the company behind Facebook and Instagram, uses an auction to decide which ad a person sees. Your willingness to pay matters, but so do ad quality and the likelihood that someone will take your desired action. When more advertisers compete for the same audience, costs can rise. Location, season, and audience size also play a part. A narrowly defined audience is not automatically more profitable. Start with people who could realistically buy and locations you can serve. Avoid adding restrictions unless you have customer evidence that gives you a reason to use them.

Why your ad and campaign objective matter

Your campaign objective tells the platform which result to pursue: visits, enquiries, or sales. If you choose visits, a cheap click does not prove you will attract customers. Choose an objective that matches your business goal and check that the relevant actions are recorded correctly. Ad creative means the image or video and the accompanying copy. Show the product in use, explain who it helps, and make the next step clear. Test different selling points, rather than changing colours alone. After the click, your landing page should deliver on the same promise and make buying or enquiring straightforward.

How to set a useful test budget

Start with what remains from a sale after product costs and other variable costs, such as delivery you cover or payment fees. Use that amount to decide what you can spend to acquire a customer while keeping your desired profit. For services, consider how often enquiries become signed contracts. Allocate an amount the business can afford to lose without disrupting its regular expenses. Focus the test on a clear offer instead of spreading spending across many campaigns. Decide what to measure, when to review, and what would trigger a stop. Allow for the time customers need to make a purchase.

How to tell whether your ads are worth it

Ads are worth running when they bring customers at a cost your business can sustain. Track customer acquisition cost, rather than clicks or reactions alone. For online shops, return on ad spend, or ROAS, is attributed revenue divided by advertising spend. It is not profit: product costs, delivery, returns, and campaign management still need covering. For services, review qualified enquiries, meaning requests that fit your offer, and the contracts they produce. Compare platform reports with paid orders and sales records. If performance disappoints, investigate the ad, landing page, and sales process. Increase spending when repeated results support the decision.

In short

Decide what you can afford to pay for a customer, test a clear offer, and assess results against what remains after costs. Base the decision to continue or increase spending on profitable sales.
