A new savings calculator widget has been launched by Halifax that webmasters and financial bloggers can add to their site easily – and for free.

The tool could be handy for those looking to target the many savings-savvy surfers out there at the moment who want to get the New Year off to a great start by planning a nest egg or financial safety net for 2012 and beyond.

All you need to do to put it on your site is click the link at the bottom of the widget that says ‘add this calculator to your site’ and you’ll be given a slice of code that allows you to post it wherever you’d like.

A Cash ISA allows you to save tax free. This is because you pay no tax on the interest you earn.
