See what your locksmith business actually nets after parts, vehicle costs, labor, and overhead — with profit per job as the key performance metric.
Five calls a day at $180 a call is $3,900 a week, and on the whiteboard that looks like a thriving business. Then the transponder blanks, the van's $453-a-month payment, the commercial insurance, the fuel burned circling a strip mall at 2 a.m. for a lockout, and the labor all take their cut — and half to sixty percent of that gross is gone before a dollar reaches your pocket. This calculator structures the locksmith model around jobs per week and working weeks per month, because weekly job count is how mobile operators actually think about their workload.
You enter Jobs Per Week, Working Weeks Per Month, Average Job Value, Materials/Parts Cost (%), Monthly Labor Cost ($), Monthly Vehicle/Fuel ($), Monthly Overhead ($), and Monthly Marketing ($). The tool returns Gross Revenue, Net Profit, and Profit Per Job — the metric that tells you whether your service pricing is actually working.
Setting a blended average when a lockout and a master key system aren't the same animal
Locksmith services span a wide price range: a residential lockout might run $75–125; a commercial lock rekey is $140–280; automotive key programming can reach $200–450 depending on make and model; a safe opening or master key system installation can run $400–1,200+. The Average Job Value ($) field should reflect your blended average across all call types in a typical week, not your highest-value service.
Operators who specialize in automotive key programming typically have higher average job values but may also have higher materials costs (transponder keys, key blanks, programming equipment). Residential emergency operators run lower average tickets but faster cycle times. Run the calculator at your actual blended average first, then run a second scenario where you model a service mix shift toward higher-value calls to see what the margin impact would be.
Parts and materials: the cost that varies by call type
Materials/Parts Cost (%) is the most variable expense in locksmith operations. A lockout call with no hardware replacement may have near-zero parts cost; a complete commercial rekeying job with new cylinders can run $40–120 in hardware. Automotive keys — especially high-security transponder keys and proximity fobs — can cost $25–90 per key depending on the vehicle. A rough industry range for blended materials cost is 15–30% of service revenue.
The percentage approach in this calculator captures the average cost structure across your call mix. If you are running below 15% parts cost, you may be doing primarily labor-intensive lockout work. If you are above 30%, you are likely doing significant hardware replacement or automotive programming work where parts costs are higher. Knowing your percentage lets you test whether changing your service mix would improve overall margin.
Service van overhead: the cost most mobile trade owners undercount
A service van or truck is the business's most essential asset and one of its largest ongoing costs. Monthly Vehicle/Fuel ($) covers not just fuel but also insurance on a commercial vehicle, routine maintenance, tires, and the depreciation reserve on the vehicle itself. A well-maintained service van in a metro area can easily cost $1,200–2,200/month all-in when fuel, insurance, and maintenance are combined.
Many locksmith operators underestimate vehicle cost because they do not amortize the cost of the vehicle itself. A $38,000 service van over 7 years is $453/month before insurance, fuel, or maintenance. Loading all vehicle-related costs into the Monthly Vehicle/Fuel field gives you an honest per-job vehicle cost when you divide the monthly total by monthly jobs — and helps you see whether a second vehicle or an additional technician makes sense at current revenue levels.
Labor cost and the solo-operator blind spot
Monthly Labor Cost ($) captures wages for any employees or subcontract technicians who perform jobs. Solo operators often leave this at zero — but that creates the same problem as any owner-operator business where the owner's time is invisible. If you plan to hire or take on a partner, loading a realistic labor cost into the model now shows you whether the business can afford it at current job volume and pricing.
For operations with multiple technicians, load all technician wages here. Monthly overhead would then include your own management time as a salary line. The goal is to see a net profit figure that reflects what remains after you have paid everyone who does the work, including yourself — not just the number before your own time is accounted for.
Emergency callers don't price-shop, but your ad budget still has to clear
Locksmith marketing carries an unusual challenge: most calls are emergency-driven, which means Google Ads and local search presence are disproportionately valuable. A locksmith in a competitive metro can spend $800–2,500/month in Google Local Services Ads or pay-per-click just to compete for emergency lockout calls. The return is typically strong — emergency callers are not price-shopping — but the cost is real and must be factored into net profit.
Monthly Marketing ($) captures all of this spend. The calculator folds it into total expenses to show net profit after marketing, rather than letting operators see a gross margin that does not account for the customer acquisition cost. A locksmith spending $1,200/month on ads at 40 jobs/month has a $30/job marketing cost — meaningful on a $150 average ticket but reasonable if the ads are producing quality calls with strong close rates.

Who it's for
- Solo locksmith evaluating a second technician — An owner running 5 jobs/week at $195 average adds a $2,800/month technician and models the weekly job volume they would need to maintain current net profit — then evaluates whether the market demand supports it.
- Mobile locksmith deciding whether to specialize in automotive — A tech who currently does 40% automotive at a $280 average and 60% residential at $110 models a service mix shift to 70% automotive and sees the effect on average job value and monthly net profit before investing in additional programming equipment.
- Startup operator setting first-year income targets — A pre-launch locksmith with $3,400 in estimated monthly overhead runs the model at 12, 20, and 28 jobs/week to see net profit at each volume tier and sets a realistic 90-day ramp target.
- Established operator reviewing marketing ROI — A locksmith spending $1,500/month on ads who cuts back to $600/month and loses 4 jobs/week models whether the reduction in net profit is worth the marketing savings — and decides to test a $900/month level first.
Key terms
- Profit per job
- Monthly net profit divided by total completed jobs. The per-call efficiency metric for mobile service businesses — independent of volume, it measures the quality of each service transaction.
- Materials and parts cost
- The direct cost of hardware, keys, cylinders, blanks, and consumables used per service call. Expressed as a percentage of service revenue in this model to enable consistent margin tracking across varying job types.
- Commercial vehicle overhead
- The combined monthly cost of owning and operating a service vehicle — fuel, insurance, maintenance, and amortized depreciation. Often the second-largest expense category after labor in mobile service businesses.
- Local Services Ads (LSA)
- Google's pay-per-lead advertising format for local service businesses, including locksmiths. Charges are per qualified lead rather than per click, making cost-per-acquisition more predictable than traditional search ads.
Frequently asked questions
What is a realistic average job value for a locksmith in 2026?
Residential service averages vary by metro and service type: lockouts typically run $85–130, rekeying $120–250, and lock replacement $180–350. Automotive services average $150–380 for key programming depending on vehicle type. A mixed-service locksmith in a mid-size market typically has a blended average of $140–220 per job. Use your own POS or invoice data for the most accurate input.
Should I include the cost of tools and equipment in Monthly Overhead?
Yes — programming equipment, key-cutting machines, and specialized tools are business assets that depreciate and eventually need replacement. Amortize major tool purchases over their useful life and include the monthly depreciation amount in overhead. A $6,000 key programmer with a 5-year life costs roughly $100/month to own — a real cost that belongs in the model.
How do I account for jobs that require a callback or warranty work?
Warranty callbacks represent labor time with no additional revenue. If you do significant hardware installation work with a warranty, estimate the percentage of jobs that generate callbacks and adjust your effective average job value downward accordingly. Alternatively, if callbacks are rare (under 3% of jobs), they are manageable within the normal variation of a monthly average.
What profit per job should I target?
Mobile locksmiths with low overhead typically net $50–90 per job after materials and vehicle costs. Operators with employees, commercial vehicles, and significant marketing spend may net $35–60 per job on the same average ticket. Below $30 per job on standard service calls suggests pricing is too low for the cost structure or overhead has grown beyond what current volume supports.
