This calculator estimates the minimum statutory notice an employer must give on dismissal: one week after one month of service, one week per completed year from two years, capped at 12 weeks. Contractual notice may be longer. Notice pay estimates based on annual salary divided by 52 may differ from actual contractual or normal earnings. See GOV.UK.
If your employer ends your employment immediately and pays you instead of letting you work your notice, this is Pay In Lieu Of Notice (PILON). PILON is calculated on your normal pay and is fully taxable — unlike statutory redundancy pay, which is tax-free. Notice pay does not count towards the £30,000 tax-free redundancy allowance.
