NHS Pension Calculator: What You Will Actually Get

The NHS 2015 scheme builds a pension of 1/54 (about 1.85%) of your pensionable pay each year, revalued by CPI plus 1.5% while you work. So 30 years on GBP 35,000 average pay builds roughly GBP 19,400 a year, payable from your State Pension age. It is a defined benefit promise, not a pot.
