The wrong hourly cost
Counting only the mechanic’s wage means forgetting rent, energy, tools and the hours you pay for but don’t bill. A two-mechanic workshop with £12,000 of monthly costs really costs £49.46 an hour.
For independent garages
Work out your real costs, test the unexpected and spot risky repairs before you lose your margin.


The problem
On the quote, everything looks profitable. It is during the job that the margin goes: one more hour, a forgotten part, an underestimated hourly cost. And nobody sees it go.
Rent, energy, tools, unbilled hours: everything is counted.
Not a table to decipher: a sentence that tells you what to do.
Precise calculations, identical every time, never estimated.
A browser is all you need: computer, tablet or phone.
Where your margin goes
Examples calculated by MecaMargin, for a workshop with two mechanics.
Counting only the mechanic’s wage means forgetting rent, energy, tools and the hours you pay for but don’t bill. A two-mechanic workshop with £12,000 of monthly costs really costs £49.46 an hour.
A seized bolt, one more part, an hour too many. On a brake job charged at £1,000, a single part at £180 is enough to drop below a 20% margin.
Underestimating the time on every brake job is not an accident: it is a habit, and it costs you on every repair. MecaMargin spots it and corrects your next quote.
Features
Everything is included in the subscription. Nothing unlocks by paying more.
The margin, the rate and the minimum price appear as you type.
5 levels, from very comfortable to loss-making, each with the sentence that says why.
One more hour, one more part, £200 of unexpected costs: one click, and you see what would be left.
How many hours the repair can still absorb before falling below your minimum margin.
When you close a repair, the variance is broken down: hours, parts, costs, price. To the cent.
MecaMargin spots what always drifts, and suggests the correction for the next quote.
What you really earn, where you lose, what to watch: in ten seconds.
An assistant works it out in a minute, from your workshop’s costs.
One account per mechanic, at no extra cost. Only the owner changes the settings.
How it works
On day one, an assistant sets your real hourly cost. After that, three moments, none of which needs any training.
Enter the price, the hours and the parts: thirty seconds, without changing anything in your invoicing software. MecaMargin immediately shows the margin, the minimum price and the risk level.

When you close the repair, enter the hours worked and the parts bought. MecaMargin explains the variance: what comes from hours, parts, costs or price. The total adds up, to the cent.

The dashboard shows what you really earn and where you lose. When a mistake keeps coming back on a type of repair, MecaMargin spots it and suggests the correction for your next quote.
Example“Your last 6 brake jobs took 18% longer. Plan 2.4 h instead of 2 h?”

This is MecaMargin’s own engine, not an animation: change a figure and everything recalculates.
Change a figure: the analysis follows instantly. Minimum margin: 20%.
This repair can absorb 2.7 h of extra labour or £150 of unexpected costs before falling below your 20% minimum margin.
A single extra part at £180 would push the margin below your minimum.
