Advanced Salary Calculator
Advanced Salary Calculator Sri Lanka
Build a simple payslip, adjust earnings and deductions live, and see take-home pay together with employer-side payroll costs.
Earnings
Monthly earnings items
The first line is treated as Basic Salary, and EPF / ETF eligible earnings are calculated automatically from that amount.
Deductions
Other deductions
These deductions are treated as additional post-payroll deductions on the payslip and are not used to reduce APIT.

How this calculator works
- Add earnings line items the same way most Sri Lankan payroll sheets are structured. EPF / ETF eligible earnings are derived automatically from the Basic Salary line.
- Pick the APIT mode that matches the case: primary employment, secondary/no declaration, or employer-borne tax on tax.
- The page updates the payslip summary in real time so users can see take-home pay, APIT, EPF, ETF, and total employer cost together.
Worked example
With total monthly earnings of LKR 250,000, the current setup can show APIT, employee EPF, employer EPF/ETF, and a live take-home estimate without leaving the page.
Important assumptions
- Primary-employment APIT follows the Inland Revenue Department monthly tables for year of assessment 2025-2026, effective from 2025-04-01.
- The secondary / no declaration mode uses the higher withholding-style monthly table commonly applied where the employee has not furnished a primary declaration or has multiple employments.
- The employer-pays-tax mode uses the tax-on-tax monthly table so the APIT is added to employer cost rather than deducted from employee take-home pay.
- EPF and ETF are shown at the common statutory rates: employee EPF 8%, employer EPF 12%, employer ETF 3%. This calculator derives EPF / ETF eligible earnings automatically from the Basic Salary amount.
Methodology & trust
Last updated March 2026 · Reviewed by Lankacalculator editorial team
- This tool converts the inputs into payroll or tax estimates using the salary, deduction, and band logic defined for the calculator.
- The output is designed as a planning estimate and can differ from a real payroll result if allowances, exemptions, or employer-specific rules are different.
- Where the calculation depends on tax bands or payroll structure, the calculator assumes the published rule set already reflected in the site data.
How to verify this
- Check the current Sri Lankan tax bands, APIT guidance, and payroll rules before using the result for a formal decision.
- Review payslip structure, employer deductions, and benefit treatment if your package is not a simple salary-only case.
- Confirm final values with payroll, finance, or a qualified tax professional when the number affects contracts or compliance.
This calculator is built for fast salary planning, not as a substitute for official payroll processing.
Using this result
When to use it
- Use this before negotiating salary, reviewing a payslip, or planning take-home pay.
- Use it when comparing gross salary, deductions, and employer-side cost together.
- Use it again whenever tax bands, allowances, or salary structure changes.
How to read it
- Separate gross pay, employee deductions, and employer cost instead of reading only one number.
- Treat the output as a planning figure until the real payroll setup and tax method are confirmed.
- Check whether the result is monthly, annual, or both before comparing it with an offer.
Common mistakes
- Confusing annual tax, monthly withholding, and retirement deductions.
- Ignoring bonuses, allowances, or non-cash benefits that change the true package.
- Comparing two salaries without normalizing them to the same pay period.
Next steps
- Cross-check with a related salary or tax calculator if the decision is material.
- Review the official tax band or payroll rule if your case includes exceptions.
- Use the output to plan net pay, not just headline salary.
