HOW TO CALCULATE
TRADES BUSINESS PROFIT.
Winning jobs and generating revenue doesn't automatically mean you're making a healthy profit. Every job has direct costs, and your business also has ongoing expenses.
01. Calculate Job Revenue
Multiply the average amount charged per job by the number of jobs completed each month.
02. Deduct Direct Costs
Subtract materials, labour, subcontractors, travel, waste and other costs associated with completing each job.
03. Deduct Overheads
Account for vehicles, equipment, insurance, marketing, administration and other monthly business costs.
Example: Completing 8 Jobs Per Month
Imagine a trades business completing 8 jobs per month at an average price of £1,500 per job.
This generates £12,000 in monthly revenue.
If materials, labour, subcontractors, travel and other direct costs total £1,000 per job, the business retains £500 per job before overheads.
With monthly fixed costs of £900, the estimated monthly profit would be £3,100 before tax.
This example assumes all eight jobs are completed and paid for, with no unexpected expenses or delays.

TRADES BUSINESS FAQS.
How do I calculate profit on a building job?
Start with the price charged to the customer. Deduct materials, paid labour, subcontractors, travel and other direct job costs. Then account for your share of business overheads.
What is a good profit margin for a trades business?
A suitable margin depends on the trade, project risks, competition, labour requirements and overheads. Your pricing should cover all costs and leave enough profit to sustain the business.
Can I use this calculator for plumbing or electrical work?
Yes. It can be used for plumbing, electrical, building, roofing, decorating, landscaping and other trades. Enter figures relevant to your business.
Does the calculator include subcontractors?
Yes. Enter the average subcontractor cost per job separately from your paid labour costs.
Does it include my own wages?
Not automatically. If you work on the tools yourself, include the value of your paid labour in the labour field if you want the calculation to deduct it.
How many jobs do I need to break even?
The calculator divides your monthly fixed expenses by the amount each job contributes after direct costs. It rounds up to the next whole job.
Does this calculator include VAT?
No. VAT is not calculated separately. If you are VAT-registered, use appropriate VAT-exclusive values and account for VAT separately.
