Government officers spent months in 2025 trying to work out what the Public Administration Circular 10/2025 salary revision actually meant for their take-home pay — phased increases, deferred balances and pension bases were confusing, and spreadsheets were error-prone.

Private-sector employees and HR staff faced the reverse problem: a simple monthly salary quickly disappeared into APIT, EPF, ETF and a dozen deductions, and most online calculators used outdated rates.

This tool was built to answer both sides: a fast, transparent breakdown of any Sri Lankan monthly salary, in English and Sinhala, with the statutory rules behind every number cited and verifiable.

The calculator is maintained independently by a small Sri Lankan developer project. It is not affiliated with, endorsed by, or connected to the Inland Revenue Department, the Employees' Provident Fund, the Employees' Trust Fund, the Treasury, or any other government body.

Rates, scales and texts are maintained by developers who work with the official sources daily. Contact us through the Contact page for questions about maintenance.

APIT slabs and relief follow the IRD's published APIT Table / tables for Y/A 2025/26 and 2026/27 (personal relief Rs 1,800,000 per year under the Inland Revenue (Amendment) Act No. 2 of 2025). The slab calculations in this tool are verified against worked IRD examples.

EPF/ETF rates follow the Employees' Provident Fund Act No. 15 of 1958 (8% employee / 12% employer) and the Employees' Trust Fund Act No. 46 of 1980 (3% employer), including the EPF-able base rules.

Government salary scales (44 scales, 1,046 step rows) were generated from the checkbill.lk salary database and cross-checked to the rupee against the official Treasury API (itmd.treasury.gov.lk salarymanagementapp) — several AGS 1-2025 and MN 1-2025 rows match the live Treasury values exactly.

The phasing model of PA Circular 10/2025 (30% April 2025 → 65% January 2026 → 100% January 2027 with the first Rs 12,500 paid immediately) is verified against Treasury-published phase values for example salaries.

COLA follows PA Circular 03/2024 (Rs 17,800). The minimum-wage check follows the National Minimum Wage of Workers statutes (Rs 30,000/month or Rs 1,200/day from 1 January 2026).

Rates and scales are reviewed whenever the IRD, the Treasury or the Public Administration issue new circulars, tables or budget proposals — for example when APIT tables change, when EPF/ETF rates change, when COLA changes, or when the next phases of Circular 10/2025 take effect (65% from 1 January 2026, 100% from 1 January 2027).

Every page and the site footer show a 'Last updated' stamp with the date of the most recent review, and significant changes are posted to the News page with links to the affected calculators.

The engine is unit-tested against the published figures, so a rate change is a one-line constant edit plus a test update — verification stays reproducible.
