How to work out your garage's hourly rate, without guessing

A labour rate is not a market price you copy. It is the answer to a division: what your workshop has to earn in a year, over the hours you can actually sell. Do that sum once and you will know whether the rate down the road is high, low, or simply someone else's arithmetic.

Start with what the year has to cover

Add up everything the workshop has to pay for before it makes a penny: rent and rates, insurance, heat and light, equipment leases and finance, subscriptions and software, the front desk, the accountant, the van, the coffee. Then add the wages of the people whose time you sell — technicians and apprentices, at what they cost you, not what they take home.

Finally add the profit you intend to make. Not the profit you hope is left over: the number you are running the business to earn. If it is not in the calculation it will not be in the bank.

Then work out what you can actually sell

This is where most rate calculations go wrong. A technician on a 40-hour week does not give you 2,080 sellable hours a year. Take out holidays, bank holidays, sick days and training. Take out the hours that will go on warranty and comeback work, tidying, road tests, and waiting for parts.

What is left is your sellable capacity. Divide the money from the first step by that number and you have a rate that covers your business. Anything above it is margin; anything below it is a subsidy you are paying your customers.

Efficiency is the multiplier nobody prices

Two garages can charge the same rate and end the year in different places, because the rate only earns when hours get sold. If a job is booked at two hours, takes three, and still invoices at two, you sold two and paid for three. Do that often enough and no rate rescues you.

This is why manufacturer book times matter, and why the clock on the job matters. Not to police technicians, but because the gap between the time quoted, the time taken and the time invoiced is the most useful number in the workshop, and almost nobody has it to hand.

Rate rises are the least of it

Most garages that feel squeezed reach for the rate first, because it is the one lever that is obviously theirs to pull. It is rarely the one that moves the year. Ahead of it, in our experience of how workshop money actually behaves:

• Parts margin — a consistent markup rule, applied to the real cost you paid rather than the estimate you quoted from.
• Work that leaves unsold — an amber advisory nobody priced, or found work the customer was never actually asked about.
• Time that never reaches the invoice — the half hour on the phone, the second road test, the part fetched from the factor.

Fix those and the rate becomes a decision rather than a defence.

Knowing it, job by job

The sum above gives you a rate for the year. What tells you whether it is working is the same arithmetic per job: what the work sold for, what the parts really cost, and how long it actually took. That is what MechIQ records as a by-product of running the job — the clock runs while the technician works, the real cost-in lands when the supplier invoice is scanned, and the margin comes out per job, per technician and per customer without anyone building a spreadsheet on a Sunday.

Common questions

How do I calculate a garage labour rate?

Take your annual overheads plus the wages of the people who sell time, add the profit you intend to make, and divide by the hours you can realistically sell in a year. Sellable hours are not attended hours: holidays, training, warranty work, tidying and waiting all come out first.

What are sold hours versus attended hours?

Attended hours are what a technician is paid for. Sold hours are what ends up on invoices. The gap between them is the single biggest reason a busy garage makes less than it should, and it is why two garages with the same rate can have very different years.

Should I charge the same rate for every job?

Not necessarily. Diagnostic time, a courtesy-car job and an insurance or fleet account can each justify their own rate, and most garages already vary in practice without admitting it. What matters is that the variation is deliberate and recorded, not decided at the counter.
