Spend what it takes to buy the leads you need at a cost per lead you can afford, and no less than Meta needs to learn. The maths is simple: leads needed each month multiplied by your affordable cost per lead equals your monthly ad budget. Divide by 30 for a daily budget. Then check that each ad set can realistically get about 50 results a week, which is when Meta says ad sets usually exit the learning phase.
Any figure you see quoted without those inputs, $10 a day or $1,000 a month, is a guess. Your number depends on what a customer is worth to you, how many leads turn into customers, and what leads cost in your industry and city.
Start with the cost per lead you can afford
Work backwards from the customer. The numbers below are an illustration, not a benchmark. Swap in your own.
- What is a new customer worth? Use gross profit from their first year, not lifetime revenue you hope for. Say $600.
- How much of that will you spend to win one? Say a third: $200.
- How many leads become customers? Pull it from your CRM or booking records. Say one in five.
- Affordable cost per lead: $200 divided by 5 is $40.
If you don’t know your close rate, that’s the first problem to fix. Ads can’t be judged without it.
Work out how many leads you need
Take the customers you want each month and multiply by your lead-to-customer ratio. In the example, 20 new customers a month at one in five means 100 leads. At $40 a lead, that’s $4,000 a month, or roughly $130 a day. That’s your starting budget. Whether you can hit $40 is what the first month of testing tells you.
Check it against Meta’s learning phase
Meta says an ad set exits the learning phase once it can deliver stably, usually after about 50 results in the week after its last significant edit. During learning, performance is less stable and cost per result is usually higher. If an ad set is unlikely to get about 50 optimization events in a week, Meta marks it Learning Limited.
In the example, $4,000 a month buys about 25 leads a week at $40. That ad set won’t exit learning on lead optimization alone. Meta’s suggested fixes: combine ad sets, broaden the audience, raise the budget or bid, or optimize for an event that happens more often. For most local businesses, the practical answer is fewer ad sets with more budget each, not ten small ones.
Edits matter too. Meta lists significant edits that send an ad set back into learning: any change to targeting, creative or optimization event, adding a new ad, and pausing for seven days or more. Large budget changes can as well. Change less, less often.
What Meta ads cost: the benchmarks
LocaliQ’s Facebook advertising benchmarks, published with WordStream and updated September 2026, put the average cost per lead for leads-objective campaigns at $27.39 across industries. By category:
- Beauty and Personal Care: $50.91
- Physicians and Surgeons: $32.14
- Health and Fitness: $27.11
- Real Estate: $13.74
Use these as a rough reference, not a quote. The report doesn’t break results out by country or city, and costs vary by industry, city, season, offer and creative. A Toronto med spa and a small-town gym are in different auctions. Your own first month of data beats any benchmark.
How much to spend on a test
A test needs enough budget to produce results you can read, and enough time to leave the learning phase alone. Our rule of thumb:
- One campaign, one or two ad sets, three to five creatives.
- A budget that can produce at least 20 to 30 leads before you judge anything. At a $40 target, that’s $800 to $1,200.
- At least a week without significant edits. Meta recommends waiting to edit until an ad set is out of learning, because early results aren’t necessarily indicative of future performance.
- Judge on cost per lead and lead quality together. Cheap leads that never book are expensive.
Two practical limits for new accounts. Meta sets minimum budgets that vary by country and objective, and if you use a cost per result goal, your daily budget should be at least five times that goal. Meta also sets a daily spending limit for most new ad accounts, which rises as you build history and spend near it.
Daily or lifetime budget?
A daily budget is an average, not a cap. Meta may spend up to 75% over it on days with better opportunities, but won’t spend more than seven times the daily budget in a calendar week. A $100 daily budget can spend $175 on Tuesday and still stay under $700 for the week.
A lifetime budget sets the total for the whole campaign. With standard delivery Meta aims to spend it evenly, but may spend more on days with better opportunities and less on others. Use daily budgets for always-on lead generation. Use lifetime budgets for anything with fixed dates: a launch, an event, a seasonal offer.
Ad spend is not the management fee
Ad spend goes to Meta, charged to the payment method on your ad account. In Canada, Meta adds GST/HST at the local rate unless you add your GST/HST number to the account. A management fee is what you pay a person or agency for strategy, creative, setup, lead forms and weekly optimization.
Keep them separate on paper. Your true cost per customer includes both, but only ad spend tells you whether the ads work. Be wary of any arrangement where you can’t see what Meta was actually paid. At Socialite, ad spend is paid directly to Meta and management sits in the retainer. Read what a social media retainer includes, see our services, or talk to us about paid social.
So is it worth it?
Meta ads are worth it when your affordable cost per lead sits above what leads actually cost in your market, and when someone replies to every lead within minutes. If the maths only works at a cost per lead half the benchmark for your industry, fix the offer, the price or the close rate first. More spend won’t fix it.
