What does your detailing business actually make?

Revenue is the easy number. Profit is the one that decides whether you can hire, buy a second van, or take a week off. Put in a normal month and see what's left once everything comes out.

What comes in

Jobs per month

Average job value

Add up last month's invoices and divide by the number of jobs.

Cost per job

Supplies per job

Chemicals, pads, towels, water — averaged across jobs.

Paid by card

What share of jobs is paid by card rather than cash. Card payments carry 2.99% + $0.30.

Monthly costs, whether you work or not

Payroll

What you pay employees. Leave at zero if you're solo.

Vehicle, fuel and equipment

Insurance

Software and subscriptions

Everything else

Storage, phone, marketing, accountant, licences.

Monthly profit

$4,636

A 70% margin on $6,600 of revenue.

Break-even

$154.53

After everything, including your fixed costs spread across the month.

How this is worked out

Revenue: Jobs per month × average job value.
Variable costs: Supplies × jobs, plus card processing of 2.99% + $0.30 on the share of jobs paid by card.
Fixed costs: Payroll, vehicle and fuel, insurance, software and everything else — the money that goes out whether you work or not.
Break-even: Fixed costs ÷ contribution per job, where contribution is the average ticket minus supplies and processing for that job.

This is a working month, not a tax return — it doesn't handle depreciation, owner draw, loan principal or quarterly taxes, and you should treat what's left as pre-tax. If you pay yourself a wage, put it under payroll so the profit line means what you think it means. Nothing you type leaves your browser.

These numbers already exist — you're just retyping them

DetailerMade tracks revenue, expenses and mileage as the work happens, so your margin is on a dashboard instead of in a calculator once a quarter.
