To price a plumbing job, add burdened labor, marked-up materials, and overhead, then divide by one minus your target margin. In Housecall Pro’s example, a $750 job sells for $1,000 at a 25 percent margin.

Labor is the line to get right first. In construction, benefits add about 44 cents to every dollar of wages, per BLS employer cost data for June 2026, and many pricing examples assume far less.

All figures below were checked on October 1, 2026, and each one names its source.

Key takeaways

  • Price = total job cost ÷ (1 − target margin). Housecall Pro’s example turns a $750 cost into a $1,000 price at a 25 percent margin.
  • Construction employers paid $51.96 per hour worked in June 2026: $36.13 in wages and $15.84 in benefits, a 43.8 percent load on wages (BLS).
  • Housecall Pro puts typical residential labor at $80 to $130 an hour and service call fees at $75 to $150, without naming a dataset.
  • Measured margins are thin: 5.7 percent net for incorporated plumbing and HVAC contractors in IRS 2022 data, and 13.0 percent for the average plumbing business in BizBuySell’s 2021 benchmarks.

What is the formula for pricing a plumbing job?

The standard formula is price = total job cost ÷ (1 − target profit margin). Total job cost is burdened labor plus materials plus the job’s share of overhead.

Housecall Pro’s guide shows a $750 job at a 25 percent margin: $750 ÷ 0.75 = $1,000.

Build the price in four steps:

  1. Labor: multiply your burdened hourly cost by the hours the job will take.
  2. Materials: add the parts and supplies, plus sales tax and your markup.
  3. Overhead: divide monthly overhead by monthly billable hours, then multiply by the job’s hours.
  4. Price: divide the total cost by one minus your target margin.

Divide by one minus the margin rather than adding the margin to cost. Adding 25 percent to a $750 cost gives $937.50, which is only a 20 percent margin on the price.

Even vendor guides mix the two up. Housecall Pro’s hourly example multiplies a $103.75 break-even cost by 1.20 for a “20% profit margin.” That is a 20 percent markup and a 16.7 percent margin: $124.50 priced, $20.75 of profit.

A true 20 percent margin on the same cost prices the hour at $129.69 ($103.75 ÷ 0.80).

How do you calculate your labor cost?

Housecall Pro defines burdened labor as wages plus payroll taxes and employer benefits, with nonbillable time such as drive time, supply runs, and setup built in.

Start with the wage, then add what the employer pays on top of it. Plumbers earned a median $63,800 in May 2025 (BLS), which works out to $30.67 an hour over a 2,080-hour year.

The employer’s cost is higher. BLS employer cost data for June 2026 puts the construction industry at $51.96 per hour worked: $36.13 in wages and salaries and $15.84 in benefits.

Construction employer cost per hour worked, June 2026BLS Employer Costs for Employee Compensation, June 2026, construction industry: total compensation $51.96 per hour worked, wages and salaries $36.13 (69.5 percent), benefits $15.84 (30.5 percent). Retrieved October 1, 2026.What an hour of construction labor costs$51.96per hour workedWages and salaries$36.13 an hour (69.5%)Benefits$15.84 an hour (30.5%)Source: BLS, Employer Costs for Employee Compensation, construction, June 2026
Benefits made up 30.5 percent of construction labor cost in June 2026. Source: BLS Employer Costs for Employee Compensation, Table 4, retrieved October 1, 2026.

Divide benefits by wages and you get the load: $15.84 ÷ $36.13 is 43.8 percent. BLS splits benefits into paid leave, supplemental pay, insurance, retirement and savings, and legally required benefits.

Applied to the median plumber, $30.67 an hour becomes about $44.11 an hour in employer cost. That figure is an industry average across construction jobs, so check it against your own payroll.

Pricing guides often assume less. Jobber’s worked example adds 20 percent to a $24 rate, and Housecall Pro says a $35 plumber might cost $43 to $48, a 23 to 37 percent load. The BLS construction average sits above both.

Account for hours you cannot bill

Burdened cost is per hour worked, and not every hour worked is billable.

Drive time, supply runs, and estimates that never close all cost wages. Divide your burdened cost by the share of hours you actually bill to get the labor rate a price has to cover.

How much should you mark up plumbing parts?

Simpro, a field service software maker, says materials should carry a 40 to 60 percent markup and calls it the industry standard (March 10, 2026). It names no dataset, and Housecall Pro’s guide repeats the range, crediting Simpro.

The markup covers truck stock, ordering time, handling, and warranty risk on the part.

The percentage varies by item. Housecall Pro says small consumables such as fittings and tape often carry higher markups, while large-ticket items such as water heaters usually carry lower percentage markups but more dollars.

It also advises setting the markup in your price book, so the same rule applies on every job.

Check suppliers too: Housecall Pro suggests comparing your parts costs with the averages used in national pricing guides, since a markup on inflated costs still overcharges.

Markup and margin are not interchangeable. Markup is a percentage of cost and margin is a percentage of price, so a 50 percent markup only produces a 33.3 percent margin.

Markup needed to reach a target profit marginMarkup on cost needed for each target margin on price: 20 percent margin needs 25 percent markup; 25 percent needs 33.3; 30 percent needs 42.9; 40 percent needs 66.7; 50 percent needs 100 percent. Markup equals margin divided by one minus margin.Markup you need for each target margin20% margin25% markup25% margin33.3% markup30% margin42.9% markup40% margin66.7% markup50% margin100% markupMarkup = margin / (1 – margin). Arithmetic, not survey data.
Hitting a 40 percent margin takes a 66.7 percent markup on cost. Calculated as margin ÷ (1 − margin).
Target margin on price Markup needed on cost Price of a $100 part
20% 25% $125.00
25% 33.3% $133.33
30% 42.9% $142.86
40% 66.7% $166.67
50% 100% $200.00

Arithmetic: markup = margin ÷ (1 − margin); price = cost ÷ (1 − margin).

How do you build overhead into a plumbing price?

Turn overhead into an hourly charge. Jobber’s guide divides monthly overhead by monthly billable hours: $4,000 of overhead over 500 billable hours is $8.00 an hour, so a two-hour job carries $16.00 of overhead.

Overhead is everything that keeps the doors open but is not tied to one job: vans, fuel, insurance, the office, marketing, and software. If you leave it out, every job looks profitable while the bank balance says otherwise.

For scale, BizBuySell’s 2021 benchmarks put operating expenses for the average plumbing business at $554,576 on $1,680,532 in revenue, or 33.0 percent.

That is separate from the 55.0 percent spent on cost of goods sold ($924,293). BizBuySell reports a 13.0 percent net margin for the same year.

Should plumbers use flat rate or hourly pricing?

Most plumbers use both, according to Housecall Pro, which recommends flat rates for routine residential work, because the customer approves a known price, and hourly billing for diagnostics, older systems, commercial time-and-materials jobs, and work whose scope can change.

Flat rates move the risk of a slow job onto the shop. They work when the price book is built from the same formula above, so each flat price covers burdened labor for a realistic job time, marked-up parts, overhead, and margin.

Hourly billing protects you on open-ended work but invites the customer to watch the clock. Housecall Pro’s guide quotes two plumbing shop owners who say a flat-rate price book makes prices easier to explain and keeps every technician quoting the same number.

ResQ’s guide describes a hybrid model: charge time and materials for the diagnostic phase (inspection, testing, camera work), then switch to a flat rate for the repair once you know what you are dealing with.

It says the customer then pays a known price for the fix, while the shop is protected during discovery, when surprises are most likely. ShiftFlow makes the same split: flat-rate the catalog and bill time and materials for genuine unknowns.

Price books live in field service software. Our comparison of plumbing estimate apps covers which tools handle flat-rate price books.

What do plumbing companies charge for labor and service calls?

Vendor guides put residential plumbing labor at $80 to $130 an hour. Housecall Pro gives that range, with commercial rates often starting at $100 and emergency or after-hours work at $150 to $300, or 1.5 to 3 times the standard rate.

For service and diagnostic calls, Housecall Pro says most residential shops charge $75 to $150, within a wider $50 to $200 range. Jobber says $75 to $125.

Housecall Pro lists add-ons for harder jobs: 10 to 20 percent for tight spots such as slabs, crawlspaces, and attics, 5 to 10 percent for premium materials such as copper or PEX-A, and 10 to 15 percent for permits, special equipment, or multi-day work.

As a rough benchmark, it says high-cost metros such as New York, San Francisco, and Chicago may need prices 15 to 25 percent above national averages, while rural or lower-cost markets may land 10 to 20 percent below.

Neither guide names the data behind its ranges, so treat them as a sense check rather than a target.

Check your own rate against them. If your formula produces a number far below the range, a cost is probably missing. If it lands far above, your overhead or nonbillable time may need a hard look.

What profit margin should a plumbing job target?

Housecall Pro calls a 20 percent net margin a strong benchmark for plumbing companies. Measured margins are lower: 5.7 percent for incorporated plumbing and HVAC contractors in IRS data for 2022, and 13.0 percent for the average plumbing business in BizBuySell’s 2021 benchmarks.

BizBuySell’s 2021 figures also show where the money went for the average plumbing business: a 45.0 percent gross margin on $1,680,532 in revenue, and a 13.0 percent net margin.

Housecall Pro offers a pricing check: if nearly every estimate is accepted, rates may be too low. Its test is to raise your most common services 5 to 10 percent and track close rate, callbacks, complaints, and ticket size for 30 to 60 days.

The job margin in your formula has to be higher than the net margin you want, because overhead gaps, callbacks, and unbilled time eat into it. Our guide to plumbing business owner salary shows how margin turns into owner pay.

Worked example: pricing a two-hour drain job

Jobber’s guide prices a two-hour clogged drain at $164.80. It uses $57.60 of labor ($24 an hour plus 20 percent, for two hours), $50.00 of materials, $16.00 of overhead, and a 25 percent margin.

Swap in labor at the BLS construction average and the price changes. The median plumber wage of $30.67 with the 43.8 percent benefit load is $44.11 an hour, or $88.22 for two hours.

Line Jobber example With BLS-based labor
Labor (2 hours) $57.60 $88.22
Materials $50.00 $50.00
Overhead (2 hours at $8) $16.00 $16.00
Total cost $123.60 $154.22
Price at 25% margin $164.80 $205.63

Sources: Jobber, “How to Price Plumbing Jobs” (updated May 3, 2026); BLS Occupational Outlook Handbook (May 2025 wage) and Employer Costs for Employee Compensation (June 2026); all retrieved October 1, 2026.

The same job is priced $40.83 higher, about 25 percent, once labor reflects what employers actually pay. Neither version charges for nonbillable time yet, which would push the price up further.

Your own numbers will differ. Price from your own payroll and overhead, and use a guide’s example only to check the method.

How can software keep plumbing prices consistent?

Software stores the formula in a price book, so each technician quotes the same number for the same job. Housecall Pro lists a price book on its Basic plan.

Housecall Pro says quotes can drift when prices live in notebooks, spreadsheets, or a technician’s memory. It advises standardizing the price book and job-profit tracking so the whole team quotes from the same approved numbers.

Jobber Core costs $29 a month billed annually ($49 with no commitment), and Housecall Pro Basic costs $59 a month billed annually ($79 billed monthly), both checked October 1, 2026.

How to price a plumbing job FAQ

How do I charge for a plumbing job?

Add burdened labor, marked-up materials, and overhead, then divide by one minus your target margin. Use flat rates for routine work and hourly billing for diagnostics or open-ended jobs, as Housecall Pro’s 2026 guide recommends.

What is the 135 rule in plumbing?

It is a drainage code rule about cleanouts. The Uniform Plumbing Code, as adopted in Minnesota (section 707.4), requires an additional cleanout for each aggregate horizontal change in direction exceeding 135 degrees. Extra cleanouts add fittings and labor, so price them in.

The 2018 International Plumbing Code uses a different trigger: a cleanout at each horizontal change of direction greater than 45 degrees. Check which code your jurisdiction has adopted.

How do you estimate a plumbing job?

Estimate the hours, list the parts, and price each line with the formula above. A written estimate built from a price book lets the customer approve a fixed number before work starts.

How much should a plumber charge for a service call?

Housecall Pro reports $75 to $150 for most residential shops, within a $50 to $200 range, and Jobber reports $75 to $125. Neither names its data. Set your own fee from drive time, burdened labor, and vehicle cost per trip.

Why is hiring a plumber so expensive?

The hourly price covers far more than the plumber’s wage. In construction, benefits add 43.8 percent to wages (BLS, June 2026), and the price must also cover nonbillable time, trucks, insurance, and the margin a business needs to survive.
