Santhosh works at Aplenix Technologies in Tamil Nadu on a CTC of ₹12,00,000, with basic at 50% (₹6,00,000), the new tax regime and gratuity inside CTC. Employer PF is ₹36,000 a year (12% of the ₹25,000 monthly ceiling; the calculator assumes that ceiling, which applies from 17 September 2026, for the whole year) and the gratuity provision is about ₹28,846, so gross salary is about ₹11,35,154. Taxable income after the ₹75,000 standard deduction is about ₹10.6 lakh, under the ₹12 lakh rebate limit, so TDS is nil. Employee PF of ₹36,000 and professional tax of ₹2,500 leave Santhosh with in-hand pay of about ₹91,388 a month.
Gross salary is basic + DA plus allowances such as HRA and special allowance. CTC is larger: it also counts what the employer pays on your behalf, mainly employer PF (12% of PF wages), employer ESI where gross pay is within the ESI limit, and a gratuity provision of about 4.81% of wages.
None of the employer contributions reach your bank each month. From gross salary, the employer then deducts employee PF (12%), employee ESI if covered, professional tax set by your state, and income tax (TDS). What is left is your in-hand salary.
From 21 November 2025, the Labour Codes define wages as basic + DA + retaining allowance. If the other allowances are more than 50% of total pay, the excess is added back to wages for PF and gratuity. So a structure with basic at 40% of CTC pays PF and gratuity on half of gross pay, not on the 40%. This calculator applies the rule and tells you when an amount has been added back.
Offer letters, salary structures and payslips all need the same CTC split, and the 50% wage test has to be checked every time a structure changes. The wHRMS payroll module builds components from CTC, applies PF, ESI, professional tax and TDS each month, and keeps every employee's structure in one record.
