The short answer: in 2026, Facebook ads cost an average of $11.54 per 1,000 impressions (CPM) and about $0.77 per click (CPC), with an average cost per lead of $27.66. But those averages are almost useless on their own, because what you pay depends on your industry, your objective, and how much data your campaign has to work with.
Most small businesses spend $300 to $1,500 a month. You can start with far less. Whether that spend produces results is a different question, and that's what this guide is really about.
Let me give you the real numbers, then show you why your costs might look nothing like the average.

That cost-per-lead figure is the headline for most small businesses. And it swings hard: from $3.16 for restaurants to $76.71 for dentists. Whether a lead at that price is actually profitable depends on your ROAS, not the cost in isolation.
Why your costs depend so heavily on your industry
Here's the pattern that explains almost everything: the more a customer is worth, the more you pay to reach one.
i pay approximately 6300 a year for my car insurance in Toronto, so imagine them paying 76.71 for a lead acquisition is nothing comparing what you bring them annually.
Finance runs the highest CPMs, around $28.40, because a single converted policy can be worth thousands. Apparel sits near the bottom at about $5.61, because margins are thinner and a sale is worth less.
Same story on cost per click for lead ads:
Most expensive: dentists ($5.70), beauty and personal care ($2.97), furniture and home improvement ($2.18)
Cheapest: career and employment ($0.73), arts and entertainment ($0.88), sports and recreation ($1.08)
So if you're a dentist paying $5 a click, you're not doing anything wrong. That's the going rate for your auction. The trick is knowing your number instead of comparing yourself to a blended average that includes industries nothing like yours. Our free Facebook Ads cost calculator gives you a CPC, CPM, and cost-per-lead range for your specific industry and objective in a few clicks.
What does a small budget actually buy?
Let's make this concrete, because "it depends" doesn't help anyone plan.
Is $100 enough? For a real campaign, not really. At an average CPL of $10 to $30, $100 buys you roughly 3 to 10 leads before the money runs out. That's a taste, not a test.
A realistic starting point is $300 to $500 a month, or about $10 to $50 a day. That gives Meta enough data to actually optimize.
And that last part matters more than most people realize. Meta's delivery system has a learning phase: it needs roughly 50 optimized events (leads, purchases, whatever you're optimizing for) per ad set per week to stabilize. Fall below that, and your campaign can sit in learning indefinitely, with higher and more erratic costs the whole time.
This is the quiet reason tiny budgets underperform. It's not that the ads are bad. It's that Meta never got enough signal to find your buyers.
Why your Facebook ads might be more expensive than they should be
If your costs feel high, it's usually one of these:
Audience too narrow. A small audience means less competition for placement in a strange way: Meta has fewer people to deliver to, so CPM climbs. Broad often beats narrow now.
The wrong optimization event. Optimizing for awareness is fuzzy. Optimizing for a purchase or lead is precise. Precise gets cheaper results.
Weak creative. Low click-through rate raises your effective CPM. Better creative literally lowers your costs.
Q4 timing. October through December, e-commerce advertisers flood the auction for Black Friday and the holidays. CPMs jump 20% to 35%.
A brand-new ad account with no performance history yet.
How to lower your Facebook ad costs
The moves that actually work, in order of impact:
Improve creative to raise CTR. Higher relevance lowers your effective CPM. This is the biggest lever you control.
Test more than one angle. Different messages find different buyers. A price angle finds bargain hunters; a convenience angle finds busy people. Give Meta variety to work with. (An AI ad copy generator can spin up those angles in seconds.)
Broaden the audience and let Meta's algorithm find the cheapest conversions.
Try Stories and Reels placements, which often carry lower CPMs than Feed.
Set spending guardrails so a bad day can't quietly drain your budget.
That last one is where most solo advertisers get burned. Meta optimizes for delivery, not for your profit, and its bidding can push spend hard before you notice. FastiAds checks your campaign every 15 minutes against a spend cap and a cost-per-result ceiling you set, then auto-pauses and emails you if either gets crossed. It's a layer the platform doesn't give you on its own.
Plan your budget backward from a goal
Most people budget forward ("I'll spend $500 and see what happens"). Smarter to work backward from a target.
If you need 40 leads a month and your cost per lead is around $25, you need roughly $1,000 a month. The Facebook Ads cost calculator has a reverse budget planner built in: enter the leads or sales you want, and it tells you the monthly budget required, plus whether that budget can even clear the 50-events learning-phase threshold.
Frequently asked questions
How much do Facebook ads cost per month? Most small businesses spend $300 to $1,500 per month. Campaigns under about $5 a day often struggle to gather enough data to exit the learning phase, so a realistic starting budget is $500 to $1,000 per month.
Is $100 enough for Facebook ads? It can run a short test, but at a $10 to $30 cost per lead, $100 buys only 3 to 10 leads. For ongoing results, plan for at least $300 to $500 a month.
What is a good Facebook ads CPC? It depends on your industry. E-commerce traffic clicks of $0.60 to $1.20 are reasonable; competitive lead-gen fields like finance or dental commonly see $3 to $8. Your cost per result matters more than CPC alone.
Why are my Facebook ads so expensive? Usually narrow targeting, a fuzzy optimization event, weak creative, Q4 auction competition, or a new account with no history. Fixing creative and broadening the audience are the fastest ways down.
Are Facebook ads more expensive in Q4? Yes. October through December, CPMs typically rise 20% to 35% as advertisers compete for holiday shoppers.
