hi, I have had suffered from a lot of confusion and stress this year due to my payroll messing things up a few times. I am an NQT (outer London) who has been given some control over certain IT things around the school. As a result of this, my lovely school has bumped my pay up from M1 to M3 in December informing me that the payroll would pay it as back-pay in December, then due to failure, in January. This of course did not happen and PayRoll did this as a one off payment on a random day. My question is... How much shall I be receiving per month as a teacher on M3 - without paying Tpensions in outer London? I use the TES pay calculator Spreadsheet. It has worked for me give or take a few pounds when I was a trainee as well as with my M1. When I was in M1 - not paying teacher's pension but LGPS one (I cannot afford it at the moment) - I received £1,705. After bumping up to M3 which should be £1,895 according to calculator - I currently receive £1,825 only. No visible deductions or anything except tax and NI. Now, due to pay calculator being more or less spot on so far, this is confusing me a lot. My tax code is the basic 10k one. September to January back pay was also paid as £650 rather than £900 something due to difference between M1 and M3 over 5-6 months. My current pay seems to be like around M2 without TPensions, but on payslip it says SCP3. I added some screenshots for further help.. With the childcare costs increasing for us next year, I am desperate for every penny to be honest. Your help is much appreciated.
