This simulator will help you evaluate your earnings for different status.Many other dimensions should be taken into account to select a status beyond the take-home pay (separation of personal / professional assets, flexibility to open or close your business, exposure to IR35, other source of earnings or investment strategy)
Thanks to this tool you will get an indicative view of earnings based on simple assumptions. We have added the option "Inside IR35" which is only relevant if you have already opted for a Personal Service Company (Limited company) and you are about to start a project with a client that falls under IR35.
If you are targeting a specific take home pay, play on the day rate and your estimated number "billable" days to fine tune your offering
