Tax payable
Which regime comes out lower
Against the old regime with no claims, the new regime is ₹2,49,600 lower. Against the old regime claiming Section 123 (formerly 80C) and Section 126 (formerly 80D) in full, the new regime is ₹1,95,000 lower. That is arithmetic on these assumptions, not a recommendation: rent (HRA), home-loan interest and NPS change the old-regime figure, and the income tax calculator takes them all.

If ₹50 lakh is your CTC: monthly in-hand
A cost-to-company figure includes money that never reaches your account. On the salary calculator's starting assumptions, a ₹50 lakh CTC comes to ₹3,16,257 a month under the new regime and ₹2,96,084 under the old, the new regime leaving more in hand on these figures.
- Basic pay 40% of CTC, HRA 50% of basic, no rent paid
- Employer and employee PF on the statutory wage ceiling: ₹21,600 a year each
- Gratuity provision of ₹96,154 a year counted inside the CTC
- Professional tax as in Karnataka: ₹2,500 a year
Assumptions
- A resident individual under 60, with salary as the only income.
- The ₹50,00,000is the year's gross salary. The tables above take no HRA exemption, home-loan interest or NPS.
- The old regime's second column claims ₹1,50,000 under Section 123 (formerly 80C) (the whole pool; employee PF counts towards it) and ₹25,000 of health insurance for yourself under Section 126 (formerly 80D).
