Estimating & Business Calculators

Running a profitable trade business requires more than technical skill - accurate estimating and sound financial management are essential. Our business calculators help you work out competitive day rates, calculate profit margins and markup percentages, estimate job costs including materials, labour, and overheads, and produce professional quotations. Whether you're a sole trader or managing a team, these tools take the guesswork out of pricing your work.

UK construction businesses must navigate the Construction Industry Scheme (CIS), where contractors deduct 20% (or 30% for unverified subcontractors) from payments and pass this to HMRC. Our CIS calculators help both contractors and subcontractors understand net payment amounts. VAT calculators handle the standard 20% rate, the 5% reduced rate for certain renovation works, and the domestic reverse charge for VAT that applies to many construction services since March 2021. These tools reflect current HMRC rules and thresholds for the 2025/26 tax year.

Beyond tax compliance, our estimating tools help you build accurate job costings that account for material waste factors, prelim costs, contingency allowances, and the true cost of your time including holiday pay, insurance, tool replacement, and vehicle costs. Use them to ensure every quote you send out covers your overheads and delivers the profit margin your business needs to thrive.
