Are Facebook ads worth it for your practice?
They are worth it when one new client is worth more than it costs to win one. That cost is your cost per lead times the number of leads it takes to sign one client. At the 2026 median for dentists, $61.56 a lead, a practice that signs 1 lead in 10 pays about $616 in ads for each new patient.

What one new client costs in ads, by practice type
Ad spend only. Columns show the cost if 1 lead in 5, 10 or 20 becomes a client: examples to set beside your own records, not published rates.
| Practice | Cost per lead | 1 in 5 | 1 in 10 | 1 in 20 |
|---|---|---|---|---|
| Real estate agents | $13.74(2026) | $69 | $137 | $275 |
| Chiropractors | $27.11(2026, nearest category) | $136 | $271 | $542 |
| Therapists | $27.11(2026, nearest category) | $136 | $271 | $542 |
| Medical practices | $32.14(2026) | $161 | $321 | $643 |
| Plastic surgeons | $32.14(2026) | $161 | $321 | $643 |
| Dermatologists | $32.14(2026) | $161 | $321 | $643 |
| Med spas | $50.91(2026, nearest category) | $255 | $509 | $1,018 |
| Dental practices | $61.56(2026) | $308 | $616 | $1,231 |
| Law firms | $104.58(2024) | $523 | $1,046 | $2,092 |
Cost per lead: WordStream by LocaliQ’s medians for US lead campaigns, 2026 edition, and 2024 for law firms because the 2025 legal figure repeats another cell (how the figures were checked). Chiropractors and therapists use health and fitness; med spas use beauty and personal care.
The test: is a new client worth more than that?
Take the column nearest your own rate and set it beside what one new client brings in over the work you do for them. If the client is worth several times the ad cost, the ads can pay even when a month goes badly. If the two are close, a small rise in cost per lead or a slower week at the front desk wipes out the margin.
Add what you pay to make and run the ads. Oak Reel, for example, charges a fixed $2,500 a month, so with the $4,000 of ad spend it recommends, a month costs $6,500. The cost calculator does the sum with your own client value and close rate.
The budget Meta needs to learn who to show your ads to
Meta says an ad set usually leaves its learning phase “after about 50 results in the week after the ad set’s last significant edit” (Meta Business Help Center). For a lead campaign a result is a lead, so the weekly spend that reaches 50 leads depends on what a lead costs in your field:
| Practice | 50 leads a week | About a month |
|---|---|---|
| Real estate agents | $687 | $2,977 |
| Chiropractors | $1,356 | $5,874 |
| Therapists | $1,356 | $5,874 |
| Medical practices | $1,607 | $6,964 |
| Plastic surgeons | $1,607 | $6,964 |
| Dermatologists | $1,607 | $6,964 |
| Med spas | $2,546 | $11,031 |
| Dental practices | $3,078 | $13,338 |
| Law firms | $5,229 | $22,659 |
That runs from $687 a week for real estate agents to $5,229 for law firms. A smaller budget works too; the ad set just takes longer than a week to collect those 50 results. Judge the results over a month or more, not the first few days, and avoid editing the ads every week, because Meta counts a significant edit as a fresh start for learning.
When Facebook ads are not worth it
- Nobody can call a new lead back within the hour. Someone who filled in a form while scrolling forgets it quickly; Oak Reel only takes practices that call back within 15 minutes in office hours for this reason.
- A new client is worth less to you than the cost in the table at your own lead-to-client rate.
- The rules for your field rule out the ad that would work. Health practices cannot ask about a viewer’s condition, law firms answer to their state bar, and housing ads cannot be aimed by age, gender or ZIP code; each practice page lists its rules with sources, such as chiropractors and real estate agents.
- You need a full calendar this month and cannot afford a few weeks of learning first.
How to find out for your own practice
Run one campaign for a month at a budget you are willing to lose. Count the leads, how many your team reached, how many booked and how many came in, then divide the spend by the clients you signed. That number, set beside what a client is worth to you, answers the question better than any benchmark.
