In response to the recent 'budget frenzy' and speculation about whether Labour are about to break their manifesto promises, I've revived an offline tax calculator I generated some years ago and brought it up to date with all the current tax bands and allowances.
The calculator runs under MS Excel (v2010 onwards), and has all the current parameters required to work out tax due on earned and unearned income. All you need to enter is your total earnings for the year and your personal tax allowance. It will also accomodate Capital Gains and National Insurance calculations.
The big advantage of using an offline calculator is that you won't be taking the risk of sharing your intimate financial details with the rest of the internet...including any potential hackers looking for well-off victims.
You can download the Excel file (Taxsheet.xlsm) from my downloads page. You'll need to allow macros to get the calculation to run - you can either do this each time you load the file, or just adjust your Excel security settings.
Happy calculating....hope you find you can still make ends meet after 'our Rachel' has taken her extra cut !
