How much do Facebook ads cost? Budgets, CPC and cost per lead
Kahu team·Updated 1 Oct 2026·7 min read
There is no fixed price for Facebook ads. You set a budget, and Meta charges based on an auction, so costs depend on your audience, location, season, creative and how well your ad converts. The useful number is cost per lead and cost per customer, which you can only learn by running a small, well-measured test.
How Meta charges
You choose a daily or lifetime budget and a goal, such as leads or website visits. Meta shows your ad in an auction against other advertisers and charges as people see or click it. You will never spend more than your budget, but you can spend it without getting results.
What pushes costs up or down
| Factor | Raises cost | Lowers cost |
|---|---|---|
| Audience | Small, competitive, high-income | Broader, less contested |
| Season | November to December, sale periods | Quieter months |
| Creative | Generic stock imagery | Clear, specific, native-looking |
| Landing page | Slow, confusing | Fast, one clear action |
| Lead form | Too many fields | Only what you need |
Setting a starting budget
- 1Work backwards from a customerEstimate what a new customer is worth to you and what you could pay to win one.
- 2Fund a real testGive one campaign enough budget for four weeks to produce a meaningful number of leads. A few dollars a day rarely does.
- 3Keep one variableChange the creative or the audience, not both at once.
- 4Track to the saleRecord which leads became customers so you can see true cost per customer.
Signs the spend is working
- Leads arrive at a cost you can afford.
- A reasonable share of them answer when you call back.
- Some become paying customers within your normal sales cycle.
If clicks are cheap but leads are poor, the problem is usually the offer or the qualifying questions, not the budget.
Frequently asked questions
What is a good cost per lead on Facebook?
It depends on your industry and what a customer is worth. Judge it against your own margin, not a published average.
Should I boost posts or use Ads Manager?
Ads Manager gives you proper goals, audiences and reporting. Boosting is simpler but harder to measure.
How long before I know if it works?
Give a campaign two to four weeks, and longer if your customers take time to decide.
