CTC is the sum of everything the company spends on an employee in a year: fixed pay, variable/bonus, allowances, employer contributions (PF, gratuity provision, insurance premium), and perks. It is not take-home. The gap between CTC and in-hand salary - deductions and retirals - is the single biggest source of new-employee confusion.
In India
India uniquely leads with CTC in offers. Savvy candidates decode the structure: how much is fixed vs variable, and how much is “cost” (employer PF, gratuity, insurance) they'll never see monthly.
In practice
₹18 L CTC might break down as ₹14 L fixed + ₹2 L variable + ₹1.1 L employer PF + ₹0.5 L gratuity/insurance. Take-home after employee PF, PT and TDS could be ~₹95k–1.05L/month - well below “₹1.5 lakh a month.”
