Plumbing Labor Rate: Paid Hours vs Billable Hours

Contractor Lane editorial guidance. Reviewed September 21, 2026. Examples are illustrative, not industry benchmarks.

Divide the field labor dollars you must recover by the productive hours that can recover them, not automatically by every hour on the payroll. A technician can be doing necessary paid work while driving, stocking, learning or completing records. Pricing must recognize that time instead of pretending every paid hour becomes a separately billed hour.

This is a cost-planning method, not a timekeeping or wage rule. Determine what time must be recorded and paid under the applicable requirements and company arrangements. Do not change a worker's time record to make a pricing assumption work. Use your payroll provider or qualified adviser for pay obligations.

Start with one role and one consistent period

Choose a month or another period that matches your budget. List the field people included, their expected paid hours and the wages attributable to that period. Add the employer costs relevant to those wages: reviewed payroll taxes, workers compensation, benefits and other employer-paid amounts. Separate office pay if it is already recovered through overhead.

A solo owner still supplies labor. If their compensation is not recorded as employee wages, include an explicit planning allowance and keep it distinct from the accounting treatment. Otherwise the model can look profitable only because the owner is contributing unpaid capacity. Review the reporting with the bookkeeper rather than treating a planning allowance as a payroll instruction.

Build the time bridge

Start with total paid field hours. Subtract the hours in that same total that are not available for productive job delivery: paid leave, training, meetings, travel not included in the chosen job-hour basis, stocking, administration and callbacks you are not charging for. Give each hour one category. Do not subtract travel again if your productive job estimate already includes it.

Define productive consistently. A flat-rate business may not show billable hours on customer invoices, but it still needs an internal estimate of labor hours consumed by sold work. A time-and-material business may use chargeable hours. Choose the definition used by your pricing method and compare like with like when actuals arrive.

A simple rate calculation

Illustration only: a role has 160 paid hours at $32 per hour. Wages are $5,120. Suppose reviewed employer costs for the example are $1,280, giving $6,400 to recover. Forty hours of leave, travel, training and support work plus twenty hours of other nonrecoverable time leave 100 productive hours.

The wage alone is $32 per paid hour. Wages plus employer cost are $40 per paid hour. The field labor recovery requirement is $6,400 / 100 = $64 per productive hour. None of these is a customer selling rate yet. Materials, overhead, marketing, sales-linked costs and desired profit may still need to be included.

If an illustrative overhead allocation adds $30 per productive hour, labor plus that overhead recovery is $94 per productive hour before direct job materials and profit. Calling $64 the selling rate would leave that overhead uncovered. Calling $94 profit would confuse recovered costs with earnings.

Paid leave does not disappear from wages

If paid leave is included in the 160 paid hours, its wages remain part of the $5,120. Removing the leave from productive hours and then removing its pay from the cost pool understates the recovery requirement. Unpaid leave belongs outside paid hours and paid wages rather than being subtracted again later.

Likewise, training can be valuable even though it reduces this month's productive hours. Suppose eight additional hours shift from production to training while paid hours and pay stay the same. Productive hours become 92 and labor recovery becomes about $69.57 per productive hour. That is a planning consequence, not a reason to skip needed training or ask someone to train off the clock.

Watch for helpers, crews and overlapping work

A two-person crew working for three hours consumes six labor-hours, not three. If both people are counted in the cost pool, their time must be handled in the capacity model. A helper may also stock the shop or run parts. Do not count the helper as a fully independent revenue-producing truck when setting sales capacity.

Separate roles when their cost and productive mix differ enough to change decisions. You do not need dozens of departments on day one. Start with a transparent combined estimate, then split it when you can explain what additional decision the detail will support. Keep the calculations simple enough that the owner can update them after a hire or benefit change.

Reconcile the estimate with what happens

Review total paid hours, productive hours and job outcomes for the same period. An unusually low productive percentage could reflect missing work, long travel, supply problems, training or inaccurate time classification. It is not automatically a technician performance problem. Ask what caused the gap before selecting a remedy.

If pay includes commission, overtime or other variable amounts, the wage estimate may move with sales and scheduling. Update the expected labor dollars when those assumptions change; a fixed wage input cannot silently solve a variable-pay model. This guide does not calculate statutory overtime or commission-based leave pay.

The IRS recordkeeping guidance emphasizes records supporting income and expense entries. Retain the underlying payroll and cost support rather than keeping only the final hourly result. Your internal capacity assumptions should also be dated so someone can reconstruct why the rate changed.

Your rate-review checklist

• I have named the people, period and productive-hour definition.
• I have included full paid wages and reviewed employer costs.
• I have separated field costs from office overhead without duplication.
• I have counted paid leave and nonproductive hours once.
• I have distinguished labor recovery from the final selling price.
• I have a review date and actual hours to compare with the estimate.
