How Much Should a Locksmith Spend on Marketing in 2026?

The 5-10% rule (and why it's wrong)

The conventional marketing rule of thumb is 5-10% of revenue. That's a lazy answer for trades businesses. A locksmith doing $400k/year would spend $20k-$40k on marketing under that rule, which is way more than most need — and a locksmith doing $80k/year would spend $4k-$8k, which is way less than they need to get out of the starting gate.

Marketing spend for locksmiths should be based on customer acquisition cost and how many more customers you can actually service, not a percentage of revenue.

The realistic monthly spend by stage

Stage 1: Just starting out ($800-$1,500/mo total)

You need a basic website ($100/mo hosting), a Google Business Profile (free), and a small Google Ads budget ($500-$1,000/mo). Total monthly out-of-pocket: $800-$1,500. This is enough to start generating real calls and learn what's working.

Stage 2: Growing ($2,800-$5,500/mo total)

You've validated demand. Now you scale. Google Ads goes to $1,500-$3,000/mo, you start investing in local SEO and content ($500-$1,000/mo), and you hire an agency to manage it properly ($800-$1,500/mo). Total: roughly $2,800-$5,500/mo. This is where many single-city locksmiths settle.

Stage 3: Dominating ($5,000-$15,000/mo total)

You're the top locksmith in your city and want to defend the position or expand into neighbouring towns. Ad spend goes to $3,000-$8,000/mo, you have a proper website with multiple service-area pages, and the agency relationship is full-service. This is also where commercial contracts start to matter — they're high-value but require more sophisticated targeting.

Where the diminishing returns kick in

Past a certain level of Google Ads spend in a single city, you start hitting diminishing returns. You already hold most of the top spots, you're paying more to win the impressions that are left, and the marginal call costs more than the previous one. Where that point sits depends on your market.

When you hit that ceiling, the next dollar should go to: SEO content (longer payoff but better economics), commercial outreach, expanding to a second city, or improving your conversion rate on the traffic you're already getting (so you book more of the calls that are already coming in).

Working out your cost per lead

Cost per lead varies a lot by city, competition and job type, so rather than chase someone else's benchmark, track your own. Split it by the kind of work, because each behaves differently:

• Emergency calls: usually the cheapest per booked job, because most callers need someone now
• Residential jobs: often a bit more per booked call, as more people shop around
• Commercial leads: the most expensive per enquiry, but often worth far more per job
• Automotive: somewhere in between, depending on how much car work you take on

Measure these as cost per booked call, meaning a real customer who's confirmed they want service, not cost per click. The click is much cheaper; the gap is in conversion rate.

What you should not be spending on

• Yellow Pages print (still surprisingly common)
• Local newspaper advertising
• Facebook/Instagram brand awareness ads (locksmiths are intent-driven, not awareness-driven)
• Generic SEO 'monthly packages' that promise rankings without specifying what they'll do
• Lead-gen marketplaces that resell the same lead to 5 locksmiths

The honest answer to 'how much should I spend?'

Spend the most you can spend where the return is still profitable. Track cost per booked call obsessively. When the cost per call exceeds the profit from that call, you've found the ceiling. Until then, more spend = more jobs.
