About DA Calculator.in

Who We Are

DA Calculator.in is a free, independent online tool built for government employees and pensioners across India. We help Central and State Government employees calculate their Dearness Allowance (DA), Dearness Relief (DR), and arrears — accurately, instantly, and without any login or data collection.

This site was created by a Kolkata-based team with a focus on West Bengal state employees — one of the largest groups of government workers in India — who have historically struggled to find accurate, up-to-date DA information in one place.

Our Mission

Government salary structures are complex. Most employees don't know how DA is calculated, what AICPI-IW means, or how much arrear they are owed. Our mission is simple: make these calculations transparent, accurate, and accessible to every sarkari karmachari — whether they are a Class IV employee or a senior officer.

What We Cover

• Central Government DA Calculator — 7th Pay Commission, Level 1 to Level 14, updated to 60% DA (January 2026)
• West Bengal DA Calculator — ROPA 2019, updated with 38% DA announcement from Budget 2026-27, effective October 1, 2026
• DA Arrears Calculator — Month-wise breakdown for both Central and West Bengal employees, including Supreme Court order context
• Pension DR Calculator — Dearness Relief for retired Central and WB government employees and family pensioners

How We Ensure Accuracy

All DA rates on this site are sourced directly from official government publications and verified before every update:

• Ministry of Finance, Government of India — Central DA notifications and Office Memoranda
• Department of Personnel & Training (DoPT) — Pay matrix, allowance rules, and 7th CPC implementation orders
• Labour Bureau, Government of India — Monthly AICPI-IW index data used for DA calculation
• West Bengal Finance Department — State DA, ROPA 2019 notifications, and budget announcements

We update our calculators within 24 hours of any official DA announcement. All calculations are performed locally in your browser — no salary data is ever sent to our servers.

Privacy & Data Policy

We do not collect, store, or share any personal or salary data you enter into our calculators. All calculations happen entirely in your browser using JavaScript. We do not require registration, login, or any personal information. The only data we collect is standard anonymous web analytics (page views) to understand which calculators are most useful to our users.
