Welcome to ContractorCalculator, the UK’s leading website for contractors and freelancers.
We’ve been online and independent since 1999, when we launched ir35calc.co.uk to help contractors count the cost of the
then newly released IR35 tax legislation.
Still owned by founder and former IT contractor Dave Chaplin, the site has grown
dramatically since then to become the expert guide to contracting. Dave is still actively involved in its management,
supported by a dedicated team of contractors and freelancers.
Our monthly audience of regular readers is made up of contractors,
freelancers, interims and consultants from the IT, telecoms, engineering, oil, gas and energy, business, marketing
and medical sectors. They keep coming back as we offer:
- A comprehensive range of essential online financial, salary and tax calculators
- A high quality news service from a professional editorial team
- Expert commentary and analysis from industry and sector leaders
- More than 1,000 online articles and contractor guides suitable for beginners and veterans
- Access to leading contractor services.
As a result of this comprehensive resource for those new to contracting and experienced old-hands, we’re proud to call
ourselves The Expert Guide to Contracting, and have even published the definitive
guide to contracting – The Contractors’ Handbook:
the expert guide for UK contractors and freelancers.
Enjoy browsing through the features of our website and if you want to know more about the online marketing
solutions we offer, then please request a media pack.
