New Contract Calculator for outside IR35
I've created an online contractor income calculator
https://contractor-calculator.co.uk/
- Currently aimed at outside IR35 contractors
- See how much each month should yield based on invoice date
- Accurately account for holiday
- Factors in bank holidays
- See a breakdown of tax, student loan, profit after taxes, dividends available etc..
- View your invoice and payment dates on a calendar view
- Fully independent of any accountancy firms or tax services
- No data is collected or sold
Currently it's using unverified maths and aware of a few edge cases and minor bugs that need addressing as well as visual improvements.
Future improvements:
- Support other billing cycles such as weekly and bi-weekly
- Calculate according to various tax codes
- Umbrella calculations
- Account for "other income"
- Support multiple shareholdings
Feedback on any improvements, incorrect math or general issues would be welcome to [contractcalculatoruk@gmail.com](mailto:contractcalculatoruk@gmail.com) or as replies to this post.
I built this as I found that other calculators were not the most reliable and made unwanted assumptions. They also could not give me the value of each each months invoice based on the start date and when I would be providing an invoice.
