UK Reverse Tax Calculator

When thinking about your next job it is always a good idea to have a target income to aim for. Most jobs are advertised with a gross salary amount, and our tax calculator will be able to tell you exactly what to expect to take home, but what if you know how much you need/want to satisfy your budget? How do you find the gross salary from the actual money you need to spend?

The answer is to use this tool, our Reverse Tax Calculator. Using an estimation system to take into consideration every option available on the regular tax calculator, including self employment/CIS options, we can find the gross figure from a net figure provided.

There are interesting figures to be found here, for example:

Estimating the average household budget in the UK, expenditure is around £500 per week. For someone under the age of 30, this would require a salary of over £31,000 per year.
