How much should I spend on ads per month?
Anchor it to what a customer is worth, not to a percentage. Take the gross profit a customer brings over their lifetime, divide by three, and that is the most you can pay to win one. Multiply by how many new customers you want a month and you have the budget. Divide by 30.4 for the daily number Google uses. For scale, marketing budgets average 7.8% of company revenue in Gartner's 2026 survey and 9.4% in The CMO Survey.
What is Lifetime Value (LTV)?
Everything a customer pays you over the whole relationship, not just the first sale: average sale, times purchases a year, times years they stay. This calculator then multiplies by gross margin, because you can only spend profit on ads, not revenue. Recharge measured $332 of total revenue per supplement subscriber. At a 66 percent margin that is $219 of gross profit, not a $63 customer.
What is Customer Acquisition Cost (CAC)?
What you spend to win one new customer. $6,000 a month in ads that brings 30 new customers is a $200 CAC. Health and wellness brands on paid social run $36 to $73 per new customer; med spas $145 to $320 per new patient; treatment centers $3,500 to $16,608 per admission.
What is a good LTV to CAC ratio?
3 to 1 is the most cited benchmark, and it traces back to David Skok's SaaS metrics work. Skok states it for revenue at 80 percent margin or above; applied to gross profit, as here, it is a stricter bar. Below 1 to 1 you lose money on every customer. The rule is a guideline: it does not map to one defined financial result, which is why this page shows the whole chain and lets you change every input.
How long before I can judge my ad results?
Meta says an ad set usually leaves its learning phase after about 50 results in the week after its last significant edit, and that changing targeting, creative or the conversion event restarts the clock. Google says a bid strategy can take up to 3 weeks, or 1 to 2 conversion cycles, to calibrate, and recommends judging Target CPA on at least 30 conversions over 30 days. Our own rule: do not judge a new account before it has cleared those windows.
Why does Meta need about 50 results a week?
Meta's delivery system learns who converts from the results it records. Its help center says the learning phase usually ends after about 50 results per ad set in a week. Below that it is still guessing, costs stay high and delivery is uneven. The fix when volume is low is to optimize for an earlier action that happens more often, a booked call or a form, rather than the final sale.
Does Google Ads have a learning phase too?
Yes. Google's Smart Bidding strategies show a Learning status after any change and can take up to 3 weeks to settle. Google recommends at least 30 conversions in the last 30 days before judging Target CPA, and at least 15 conversions in 30 days for Target ROAS on Search and Shopping. Google also spends up to twice your daily budget on a heavy day and caps the month at 30.4 times it.
Can a regenerative medicine clinic run Google Ads?
Not for the treatments themselves. Google's policy on speculative and experimental medical treatments does not allow ads promoting cell or gene therapies, and its own examples name stem cell therapy and platelet rich plasma. That leaves Meta, organic search, referral and email to carry the budget this calculator gives you.
Do TRT, peptide and treatment center clinics need LegitScript?
Usually. Google requires LegitScript accreditation for telemedicine providers and restricts addiction services ads to LegitScript-certified providers. You also need Google certification to keyword-target prescription drug terms. Meta requires LegitScript for telehealth and online pharmacies, and for US addiction treatment ads it requires LegitScript plus written permission from Meta.
