Your accounts are correct as you had bifurcated the salary wrongly. The correct breakdown should be as follows:
You should include in the monthly CTC the Company Contribution to Provident Fund, Superannuation, and LTA. However, I would not suggest making a notional provision for gratuity as part of CTC since the same is applicable only when the employee fulfills the conditions as mentioned in the Payment of Gratuity Act, 1972.
Suggestion on HRA
One more suggestion: HRA ideally should not exceed 50% of Basic Pay, as HRA up to 50% of Basic is permissible for tax exemption under the Income Tax Act, 1961 for employees staying in metro cities.
Please review and make the necessary adjustments accordingly.
Thank you.
