Costs that sneak back
Collection runs, clean-up, callbacks, parking and admin are still part of the job.
%
Markup is not margin
A 25% markup on cost produces a 20% margin. The calculator keeps the two separate.
Built around the real decision
What should you charge so the work is worth doing?
WorthTheJob is deliberately narrower than accounting or job-management software. It helps you challenge a quote before the customer sees it.
- Start with a two-minute quick check or open the full costing tool.
- Add materials, labour, wastage, travel, hidden time and overhead.
- Choose fixed profit, markup on cost or target margin.
- Test a discount, extra day, callback or material increase.
- Create separate internal costing and customer proposal views.
The quiet argument in your head
“If I charge what it really costs, will I lose the job?”
That fear often pulls the price down before the numbers have had a fair hearing. The tool does not tell you to charge more for the sake of it. It shows what each choice does to the money left after the work.
You know your trade. This helps make sure the numbers reward it.

Have a real quote checked
The free calculator finds the pressure points. A paid review checks the assumptions, scope, exclusions, payment stages and fragile profit before the quote reaches the customer.
See quote-review optionsWhat the review is for
Not to make the quote look expensive. It is to make the price understandable, fundable and less likely to turn into unpaid work.
See the service before trusting it
Look inside an illustrative reviewed quote.
The sample shows the submitted numbers, the profit leaks found, the payment pressure and the wording changes that could make the scope clearer.
It is a fictional bathroom example, not a manufactured testimonial.

Common questions
Before you use the calculator
Does WorthTheJob tell me what other builders charge?
No. It works from your own costs, time, overhead, risk and desired profit. A competitor’s price may not cover your business.
Are my job figures uploaded?
No. The calculator works in the browser. Figures stay on the device unless the visitor deliberately exports, prints or sends them.
Is the calculator only for builders?
No. It can be used by plumbers, electricians, decorators, roofers, carpenters, landscapers, fitters, maintenance firms and other small trade businesses.
Does it replace an accountant or contract?
No. It provides practical estimates and editable proposal wording, not tax, legal, accounting, surveying or contractual advice.
Check the job before the quote leaves your hands.
No account, no accounting lecture and no need to upload the customer’s information.
