I'm assuming you have continuous service and full time. (And I'm ignoring McCloud.)
If you worked part time before 2015, then for the 1995 and 2008 calculations below where it says 'years' use a fraction of year equivalent to the fraction of full time hours that you did.
You need to know what pension sections you are in.
- If you started after 2015, it's the 2015.
- If you started after 2008 it's the 2008 and the 2015.
- If you started before 2008 it's either 2015 and 1995 or 2015 and 2008, but not both.
First calculation. For years in the 1995 pension, take your salary now (or full time equivalent salary, if you work part time now) and multiply it by the number of years between starting and 2015, then divide by 80. You can take this pension at age 55 or 60.
Second calculation. For years in the 2008 pension take your salary now (or full time equivalent salary, if you work part time now) and multiply it by the number of years between starting and 2015, then divide by 60. You can take this pension at age 65.
Third calculation. For years in the 2015 pension, take your salary for each year between 2015 and now, add them all together then divide by 54. You can take this at state pension age.
Forth calculation. take the results of the above and add them together. This will be your annual pension if you add no more to it. If you stay in the NHS you will keep adding 1/54th or your salary to the pension every year.
