Hello,
Please clarify first about deductions in your organisation.
if there would be no deductions like PF or any other .
Than you may use :
Basic Salary : 17500 (50 % of CTC )
HRA : 8750 (50 % of Basic)
Medical Allowance : 1250 (Fixed)
Travelling Allowance : 1600 (Fixed)
Special Allowance : 5900 (Balance)
if there will be deduction of PF than please calculate @ 12 % on basic salary. TDS calculate @ 10 %.
