Considering you're getting 13fixed apart from PF. 
  
 Old Regime ( After declaring 1.5lpa in 80cc + Hra declaration 1L + Nps 50k ) = Total Tax = 1.06 L 
  
 New Regime ( With no worries of any investment ) = Total Tax = 1.05 L 
  
 I'll suggest, compare your tax and then decide. Choose old regime, if you're able to utilize full limit of exemptions of different sections, otherwise New.

Thanks for that and I have 12.2 is fixed and 0 investment

I'd suggest, go for New Regime as total tax will be around 90k. This way, you'll be having cash in hand. You can invest for your future accordingly.
