₹1,50,000 on paper, ₹1,24,331 in the bank
At 18 LPA the gap between paper and pocket is about ₹25,700 a month: ₹7,200 employer PF (inside CTC), ₹7,200 employee PF, roughly ₹11,070 of monthly income-tax TDS and ₹200 professional tax. Note the change from the lower rungs — at 12 LPA the whole gap was PF; here income tax has become the larger single piece. The PF portion (₹14,400 a month combined) is still yours, growing at EPF interest.
The tax picture at 18 LPA (FY 2025-26)
Gross salary is ₹17,13,600; the ₹75,000 standard deduction leaves ₹16,38,600 taxable, which reaches into the new regime's 15% marginal slab. Total tax including cess: ₹1,32,829 — an effective rate of about 7.8% of gross. This is firmly past the §87A zero-tax zone that protects salaries up to a 12 LPA CTC, but the marginal rate is still moderate. Under the old regime with ₹1.5 lakh of deductions the bill more than doubles to ₹2,77,243, so the new regime keeps about ₹1.44 lakh more a year here.
What 18 LPA means in practice
This is a senior individual-contributor / lead band — typically 7–12 years of experience in IT, or a strong mid-career role in product, finance or consulting. About ₹1.24 lakh a month puts a household well into the top few percent of Indian earners: a metro home-loan EMI, a car, schooling and ₹40,000–60,000 of monthly investing can comfortably coexist. At this level, structural tax planning starts to pay — an employer NPS contribution under section 80CCD(2), allowed even in the new regime, reduces taxable salary directly.
The variable-pay caveat — read before celebrating the offer
This page assumes the whole ₹18,00,000 is fixed pay. At senior-IC bands that is increasingly rare: 10–15% variable is standard, and startup offers may bundle ESOPs into the headline. An "18 LPA" offer with 15% variable behaves like a 15.3 LPA fixed package month to month — closer to ₹1.06 lakh in hand — with the balance contingent on company and personal performance. When comparing offers, compare fixed cash first; run each one through the income tax calculator for the after-tax view.
The 50% basic (labour-code) scenario
If wage-code definitions push basic to 50% of CTC (₹9,00,000), PF climbs to ₹9,000 a month per side. Gross falls slightly, so tax dips to ₹1,28,336, but the bigger PF outflow leaves about ₹1,21,105 a month — ₹3,226 less in hand, redirected into retirement savings. As of June 2026, implementation timelines vary by state and employer; senior payslips are usually restructured last.
Month by month
On the fixed-pay assumption the credit is identical across all 12 months. In reality, at this band expect variation: variable payouts, RSU vesting and bonus months will make some credits larger — treat the table above as your floor, not your ceiling. The next rungs, 20 LPA and 25 LPA, push more of each rupee into the higher slabs.
