The short answer: there’s no single right number, but you can work out your own in five minutes. Decide how many new clients you want each month, work backward through your sales call close rate and show rate to find how many booked calls you need, then multiply by what a booked call costs you. For a brand-new campaign, also make sure the budget is big enough for Meta to learn: Meta says an ad set usually leaves its learning phase after about 50 results in a week. Budget for the outcome you want, not a round number that feels comfortable.

This guide walks you through the math with clearly labeled example numbers, shows what changes the budget a coach actually needs, and explains when it makes sense to spend more, spend less, or get help.

Why “how much should I spend?” is the wrong first question

Most coaches pick a Facebook ads budget the way they’d pick a gym membership: whatever feels affordable. Then they spend $300, get a handful of likes and a couple of leads who never book, and decide ads “don’t work for coaches.”

The better question is: how much does it cost me to get one new client, and how many do I want? Once you know that, the budget almost picks itself. It also tells you when your ads are working, even if the cost per lead looks high, because what matters is what a paying client costs compared with what that client is worth to you.

If you haven’t read it yet, our guide to what a booked call really costs for business coaches covers the cost-per-booked-call framework this post builds on.

How to work out your monthly Facebook ads budget, step by step

You need four numbers. Use your own data if you have it. If you don’t, start with conservative guesses and replace them with real numbers after the first few weeks.

1. New clients you want per month. Be realistic about how many you can actually serve well.
2. Close rate on sales calls. Out of every call that happens, how many say yes?
3. Show rate. Out of every call booked, how many people turn up?
4. Cost per booked call. Ad spend divided by the number of calls booked from your ads.

Then work backward:

• Calls you need to hold = new clients ÷ close rate
• Calls you need booked = calls held ÷ show rate
• Monthly ad budget = calls booked × cost per booked call

Illustrative math (example numbers, not benchmarks)

These figures are made up to show how the formula works. They are not industry averages or client results.

• You want 4 new clients a month.
• You close 25% of the calls you hold, so you need 16 calls held.
• 80% of booked calls show up, so you need 20 calls booked.
• Each booked call costs you $100 in ad spend, so your budget is $2,000 a month.

Now compare that with what a client is worth. If your program sells for several thousand dollars, $500 in ad spend per new client (the $2,000 budget divided by 4 clients) can be a very healthy number. If you sell a $97 course, the same math tells you a call-based funnel probably isn’t the right fit, and you’d look at a different offer or funnel instead.

What if you don’t know your numbers yet?

That’s normal for a first campaign. Treat the first month as paid research. Set a budget you’re comfortable spending to learn, track every lead through to booked, showed and closed, and then rerun the math with real numbers. A spreadsheet or a CRM pipeline is enough. What you can’t do is skip the tracking, because without it you’ll never know whether to spend more or stop.

Make sure your budget is big enough for Meta to learn

There’s a second check that catches out a lot of coaches. When you launch a new ad set, or make a big change to one, Meta’s delivery system goes through a learning phase. According to Meta’s own help center, an ad set usually exits the learning phase after about 50 results in the week after its last significant edit. If it’s unlikely to get there, Meta marks it as “Learning limited”, and low budget is one of the common reasons Meta lists.

For coaches, this matters because a booked call is a fairly rare event. If you optimize directly for booked calls and your budget only buys a few a week, the campaign may never settle down. A few practical ways around it:

• Optimize for a more frequent event, such as leads or applications, while you track booked calls in your CRM.
• Consolidate. One or two well-funded ad sets learn faster than five underfunded ones.
• Leave it alone. Constant budget and audience edits keep resetting the learning phase.

A quick sanity check: multiply the cost of the result you’re optimizing for by 50, and that’s roughly the weekly spend Meta’s guidance points to for one ad set. If that’s far more than you can afford, optimize for a cheaper, more frequent result rather than starving the campaign.

What changes how much a coach needs to spend

Your offer and price point

A high-ticket one-to-one program can justify a much higher cost per client than a low-priced group program. Know your client value before you judge any ad number.

Your funnel

Webinars, applications, free calls and lead magnets all have different costs and different booking rates. We compare the two most common in webinar vs application funnels for coaches. If you run group programs, our guide to filling a group coaching program with Instagram ads covers launch-style budgets.

Your follow-up

This is the cheapest lever you have. Replying to new leads within minutes, sending reminders before calls and following up with people who didn’t book can raise your booking and show rates without spending a cent more on ads. In the example above, lifting show rate from 80% to 90% means you need fewer booked calls for the same number of clients.

Your creative and your audience

Ads that sound like you, talk about one specific problem and show your face tend to attract better-fit people than generic graphics. If you’ve been boosting posts and hoping, start with our guide to Meta ads that actually bring in clients.

Your own capacity and mindset

Ads only work if you’re ready for the calls they create. Spending more than you can follow up on, or pulling the plug after a nervous first week, wastes money. The coaches who do best treat ads as a system to improve each month, which is a big part of the business mindset work we do with clients.

Ad spend vs management: don’t forget the second number

Your ad budget is what you pay Meta. Running the campaigns well, including the creative, the funnel, the tracking and the follow-up automations, is a separate cost, whether that’s your own time, a team member or an agency. When you compare options, compare the total cost per new client, not just the ad spend.

If you’re working with a tighter budget and want the whole marketing side handled for one flat fee, She Reigns Creative has a $970/month done-for-you marketing package. It covers paid ads management, social media content, newsletters and blogs, automations and reporting, and for a limited time includes a free two-hour strategy session with our CEO, Steve Andrews. Check the page for current details.

When to spend more, and when to pull back

Scale up when your cost per new client is comfortably below what a client is worth, your calendar can handle more calls, and results have held steady for a few weeks. Increase gradually so you don’t keep throwing the campaign back into learning.

Pull back or fix first when leads aren’t booking, booked calls aren’t showing, or calls aren’t closing. More budget just makes a leaky funnel leak faster. Fix the step that’s losing people, then spend more.

FAQ: Facebook ads budgets for coaches

How much should a coach spend on Facebook ads per month?

Work it out backward: new clients you want, divided by your close rate, divided by your show rate, times your cost per booked call. That gives a budget tied to results instead of a guess. Then check it’s enough for Meta’s learning phase.

Is $500 a month enough for Facebook ads as a coach?

It can be enough to test an offer and learn, especially if you optimize for leads rather than booked calls. Whether it’s enough to grow depends on your cost per booked call and how many clients you need. Run the math above with your own numbers.

What is the Facebook ads learning phase?

It’s the period after you launch or significantly edit an ad set when Meta is still working out how to deliver it. Meta says it usually ends after about 50 results in the week after the last significant edit. Too little budget can leave an ad set “Learning limited.”

Should I increase my budget if my ads aren’t working?

Usually not. First find where people drop off: leads, bookings, shows or closes. Fix that step, then scale. Extra budget on a broken funnel only costs more.

Does my ad budget include agency or management fees?

No. Ad spend is what you pay Meta to show your ads. Management, creative and follow-up are separate costs, so compare the total cost per new client when you weigh up your options.
