How to Calculate PF and ESI in India — Complete 2025 Guide

Every employer in India with more than 20 employees is required to deduct Employees' Provident Fund (EPF) and Employees' State Insurance (ESIC) contributions from employee salaries and remit them to the respective government bodies monthly. Getting these calculations wrong results in penalties, delayed filings, and compliance notices.

This guide covers the exact calculation method, current rates, eligible wage definitions, and deadlines.

Part 1 — Employees' Provident Fund (EPF)

Who is covered under EPF?

EPF applies to all establishments with 20 or more employees. Once a company crosses this threshold, all employees earning a basic salary of up to ₹15,000/month must be enrolled. Employees earning above ₹15,000 can be enrolled voluntarily.

What counts as "basic" for PF calculation?

PF is calculated on basic salary + dearness allowance (DA). It does not include HRA, special allowance, food allowance, or other components unless the employer chooses to include them. Many employers restructure CTC to keep the basic salary below ₹15,000 to limit PF liability — this is legal but requires careful structuring.

PF payment deadline

The employer must remit PF contributions (both employee and employer share) to the EPFO by the 15th of the following month. Late payments attract interest at 12% per annum and a penalty of ₹5/day per delayed employee.

Part 2 — Employees' State Insurance (ESIC)

Who is covered under ESIC?

ESIC applies to establishments with 10 or more employees in notified areas. Employees earning a gross salary of up to ₹21,000/month (₹25,000 for persons with disability) are covered.

ESIC contributions must be remitted by the 15th of the following month. Late payment attracts simple interest at 12% per annum.

Part 3 — Automating PF and ESI calculations

Manual PF and ESI calculation in spreadsheets is error-prone. Common mistakes include:

• Using gross salary instead of basic+DA as the PF base
• Not applying the ₹15,000 cap on the PF wage ceiling correctly
• Missing newly joined or resigned employees mid-month
• Incorrect pro-rata calculation for employees joining or leaving mid-month
• Forgetting to update rates when the government revises them

Payroll software like Peymatrix calculates PF and ESI automatically based on each employee's salary structure, applies the current statutory rates, handles mid-month joiners and leavers with pro-rated calculations, and generates the challan files ready for payment.
