An example of the savings for employers could be:
An employer has a staff member who is under 25 and they encourage them on to an apprenticeship. If the staff member is earning £18,000 per year, on employers national insurance rate of 13.8% (the first £8,840 earned is not subject to NIC anyway) the £9,160 that is subject to NIC gives the employer a saving of £1,264 that they no longer need to pay, for the entire time the staff member is on an apprenticeship and under 25. The same applies to new hires.
This also includes people already on an apprenticeship as long as they are still under 25.
