Ask ten workshop owners in Delhi how they arrived at their labour charges and most will say the same thing: they looked at what others charge and stayed a little below. That tells you what customers will tolerate. It tells you nothing about whether the work pays for your rent, your technicians and you.
Calculating labour charges for a car workshop properly takes four numbers and about half an hour. You need what your people cost, what the shop costs, how many hours you actually bill, and the profit you want on top. The method below works for a mechanical garage, a bodyshop or a detailing and PPF studio, because all of them sell the same thing in the end: skilled hours in a bay.
Step 1: what your technicians really cost
Start with everyone whose time you bill as labour: mechanics, denters, painters, detailers, installers. For each, take the full monthly cost, not just the salary. That means salary, any incentive you pay on jobs, overtime, PF and ESI if you are covered, and the small things that add up, such as meals, tea and the Diwali bonus spread across the year. Advances are not a cost; they come back. The hiring and pay guide covers the pay structures and statutory registrations in more detail.
Leave out the people whose time you don't bill, such as the service advisor, the washer who preps cars and the accountant. They are real costs, but they belong in step 2.
Step 2: what the shop costs to keep open
Add up a normal month of everything else: rent, electricity (compressors, the paint booth and air conditioning are not cheap in a Delhi May), water, equipment loan EMIs, consumables you don't bill line by line (rags, masking tape, cleaners), software, insurance, the advisor's and helpers' salaries, and your CA's fee.
Then add one line most owners skip: a salary for yourself. If the shop only breaks even because you work six days without paying yourself, the labour rate is too low. You are subsidising every customer with your own time.
Step 3: count billable hours honestly
This is where most rates go wrong. A technician present for 9 hours a day, 26 days a month, is paid for 234 hours. He does not bill 234 hours. Part of the day goes to waiting for a part, waiting for the customer to approve an extra, moving cars, cleaning the bay, a comeback that nobody pays for, and the slow afternoons during the monsoon when half your bookings don't turn up.
The honest way is to measure it. For two or four weeks, compare the hours each job card says were billed with the hours your technicians were on the floor. The ratio is your utilisation. If you have no records yet, pick a cautious figure and correct it later; it is safer to start low than to price on a fantasy of full bays.
Step 4: the calculation, with an example
Cost per billed hour is your monthly technician cost plus your monthly shop cost, divided by billed hours. Your labour rate is that cost plus the profit you want. Here is an illustration with round numbers. They are not benchmarks; use your own.
- TechniciansFour technicians, all-in cost ₹1,60,000 a month between them.
- ShopRent, power, EMIs, support staff, consumables and the owner's salary: ₹1,40,000 a month.
- Billed hours4 technicians × 234 hours on the floor = 936 paid hours. At 60% utilisation, about 560 billed hours.
- Cost per billed hour₹3,00,000 ÷ 560 = about ₹536. Below this, every hour of labour loses money.
- Labour rateAdd 30% for profit and the hourly rate is about ₹700, before GST.
Two things fall out of this immediately. First, utilisation moves the rate more than salaries do. Push the same shop from 60% to 70% and the cost per billed hour drops by about a seventh, with no pay cut. Second, if your current rate sits below your cost per billed hour, discounting labour to win the parts margin is a losing trade. The profit margin guide explains why labour is where a workshop's margin actually lives.
Hourly rate or fixed price per job?
Most Indian customers don't want an hourly bill. They want to hear that a periodic service, a bumper respray or a ceramic coating costs a fixed amount. That's fine. The hourly rate is not what you print on the board; it is what sits under every fixed price.
For each job on your menu, write down the time it takes a competent technician from start to finish, including prep and cleanup. Multiply by your labour rate and round to a price you are comfortable saying out loud. Then check it against real job cards every few months. If a full-body polish keeps taking longer than you priced, either the price or the process needs to change.
For detailing and PPF work, labour is most of the bill, so this matters even more. Pair the hours with film cost per job, as described in PPF roll tracking, and you have a floor price for every package.
Labour on the invoice
Show labour on its own line, separate from parts. Labour is a service and parts are goods, they carry different GST codes, and when they are shown separately each is taxed at its own rate. A single line reading “service and parts” invites questions from customers and from your CA. The GST invoice format guide lists every field a workshop invoice needs.
Mistakes that keep labour rates too low
- Copying the shop next door. Their rent, staff and utilisation are not yours.
- Not charging for diagnosis. An hour spent finding a fault is an hour of skilled labour, even if no part is replaced.
- Ignoring comebacks. Rework hours are real hours. If they are frequent, they belong in your cost, and in a conversation with the technician.
- Never revising. Salaries and rent go up every year. Recalculate at least once a year, and whenever a big cost changes.
- Leaving yourself out. If the owner's salary is not in the shop cost, the shop is not really profitable.
Where Kenro fits
The calculation needs records that most workshops don't keep: what was billed as labour on each job, how long cars sat in each stage, and what the team costs each month. Kenro Workshop keeps them as a side effect of running the floor. Your services and their prices live in your own catalogue, labour and parts go on the job card as separate lines, the GST invoice is raised from that card, and the bay board records when each car moved between stages. Attendance, salaries and advances are on each staff member's record, and expenses are counted, so the four numbers above are a report rather than an evening with a calculator. The garage billing software page shows how a job card becomes the bill.
Questions owners ask
What is a fair labour charge per hour for a car workshop in India?
There is no official or published rate card for independent workshops; rates vary by city, segment and specialisation. A fair rate for your shop is your cost per billed hour plus a profit you can defend, which is what the method on this page calculates.
Should labour be charged by the hour or as a fixed price?
Quote fixed prices for common jobs, because customers prefer them, but build every fixed price from a standard time multiplied by your hourly rate. Use hourly billing for diagnosis and for unusual jobs where the time cannot be predicted.
Is GST charged on workshop labour?
If your workshop is registered under GST, labour is a taxable service and goes on the invoice as its own line with its SAC code, separate from parts. Confirm the current rate with your CA, as rates are set by notification and can change.
How often should I revise my labour rate?
At least once a year, and whenever rent, salaries or your utilisation change noticeably. A rate set three years ago is almost certainly below your current cost.
