Paid Ads and Analytics
Google Ads Budget Calculator
What's the right Google Ads budget for your business? Not "what's standard" — what specifically works given your margin, close rate, and average sale. Output is a defensible monthly budget and an expected lead volume.
The formula
Break-even CPL = average sale × gross margin × close rate. Anything below that = profitable lead. Multiply by target lead volume to get monthly budget.
Canadian benchmarks by vertical
Home services (HVAC, plumbing, roofing): CPL $30-$90. Min budget $2k/mo.
Legal: CPL $80-$300. Min budget $3k/mo.
Dental, cosmetic, healthcare: CPL $50-$200. Min $2.5k/mo.
B2B services: CPL $80-$400. Min $3k/mo.
Ecommerce: ROAS target 3-5x at minimum.
Talkerstein recommendation
If your break-even CPL is under $30, paid ads are very tough. Lead with organic + GBP + referral first. Once break-even CPL is over $50, Google Ads can work — start at minimum $2k/mo for 90 days to get real data.
