Free Australian Workplace Calculators

Free Australian workplace calculators built for accuracy

WorkCalc Australia provides a suite of free workplace calculators for employees, payroll teams, bookkeepers, HR managers and small business owners. Every tool is built to Fair Work and ATO standards, calibrated to current Australian law, and updated as the rules change — including the legislated Stage 3+ tax cuts taking effect on 1 July 2026.

Australian workplace law is built around three main frameworks that govern what employers must pay and what employees must receive: the National Employment Standards (NES) from the Fair Work Act 2009 covering leave and core entitlements; modern awards and enterprise agreements which add industry-specific rules on top of the NES; and ATO tax tables (Schedule 1, NAT 1004) which govern how much PAYG income tax must be withheld from each pay. Every WorkCalc calculator implements the formulas from these instruments — not interpretations, not rules-of-thumb.

What calculator do you need?

The right Australian workplace calculator depends on what you’re trying to work out. Here’s a quick guide to which WorkCalc tool fits each common situation:

• I want to know how much leave I have or will have built up → Annual Leave Calculator (for full-time, part-time and casual) or the Part-Time Annual Leave Calculator if you want a specialised view of pro-rata accrual.
• I’m a long-serving employee thinking about a sabbatical, resignation or retirement → Long Service Leave Calculator, which covers all 8 state and territory LSL Acts including pro-rata eligibility for early termination.
• I want to know my take-home pay or how much tax is being withheld → PAYG Withholding Calculator, with both FY 2025-26 and FY 2026-27 brackets, Medicare Levy, HELP/STSL and LITO.
• I’m being made redundant or resigning and want to know the tax on my leave payout → Annual Leave Payout Tax Calculator, applying ATO Schedule 7 (flat 32% for genuine redundancy, marginal averaging for resignation/dismissal).
• I’m working a public holiday and want to know what I should be paid → Public Holiday Rate Calculator, with verified penalty rates across 10 major modern awards.
• I want to know how many sick days I have available → Sick Day Calculator, using the NES 1/26 of ordinary hours formula.

Who uses WorkCalc Australia

The site is built to serve four broad audiences, each with different reasons for needing accurate workplace numbers:

Employees

Most users are employees checking entitlements before resigning, requesting leave, accepting a job offer or negotiating a salary. WorkCalc’s leave calculators help confirm accrued balances before lodging leave requests; the PAYG calculator helps compare offers on a take-home basis; the public holiday rate calculator helps verify that a payslip’s penalty rates match what the modern award says.

HR and payroll teams

HR and payroll professionals use the calculators as a second check on figures produced by HRIS or payroll software. Particularly when configuring a new employee, processing a termination, or auditing a leave balance, having an independent calculator that uses the official formulas (rather than the same software ecosystem) is valuable for catching configuration errors.

Bookkeepers and accountants

Bookkeepers reconciling end-of-year leave liability, accountants estimating client tax positions, and registered tax agents preparing client returns all use WorkCalc tools to cross-check calculations. The PAYG calculator’s FY 2026-27 mode is particularly relevant for forward-planning.

Small business owners

Owner-operated businesses without dedicated HR or payroll staff use WorkCalc to calculate one-off termination payments, sick leave balances during reviews, and PAYG for new hires before configuring payroll software.

What’s changing for Australian workplace pay in 2026-27

The 2026-27 financial year (starting 1 July 2026) brings the most material change to Australian PAYG withholding in several years:

• Stage 3+ tax cut takes effect. The second tax bracket (income from $18,201 to $45,000) drops from 16% to 15%. Every Australian taxpayer earning above $18,200 saves up to $268 per year. A further cut to 14% is legislated for 1 July 2027.
• HELP/STSL threshold rises to $69,528 (from $67,000 in 2025-26), in line with CPI indexation. The 15% marginal repayment rate continues to apply between threshold and $125,000.
• Superannuation Guarantee stays at 12%. The SG phase-up reached 12% on 1 July 2025 and that’s the permanent rate.
• Pay day super requires super contributions to be paid at the same time as wages from 1 July 2026. This doesn’t change PAYG calculations but increases payroll processing complexity.

WorkCalc’s PAYG calculator handles both FY 2025-26 and FY 2026-27 with the correct bracket structure for each year, including the legislated changes above.

Accuracy and what these calculators can’t do

WorkCalc calculators are built to match the underlying ATO and Fair Work formulas as closely as possible. The PAYG calculator’s annual figures will match an official ATO tax estimate to within rounding. The leave calculators apply the published National Employment Standards accrual rates exactly.

There are scenarios where you need to look beyond a generic calculator:

• Modern award variations. Specific industries (hospitality, retail, healthcare, building, manufacturing) often have award rules that override or add to the NES. The Public Holiday Rate Calculator lists 10 major awards by name — for others, check the award directly.
• Enterprise agreements (EBAs). A registered EBA may set more generous leave accrual, different loading rates, or specific cash-out clauses. Always check your EBA against the calculator output.
• Individual employment contracts. Above-award contracts can provide better entitlements than the NES default. Below-award contracts cannot.
• Personal tax circumstances. The PAYG calculator estimates withholding based on standard inputs. Salary sacrifice, novated leases, work-related deductions, investment income, and Medicare Levy Surcharge are reconciled at year-end via your tax return.

Why WorkCalc instead of the official Fair Work and ATO calculators?

The Fair Work Ombudsman and the Australian Taxation Office both publish calculators on their official websites. WorkCalc isn’t a replacement — it’s complementary. Three differences:

• Speed and simplicity. WorkCalc tools are designed for fast lookups. No multi-step wizards, no irrelevant fields, no signup. Type your figures, see the result.
• Combined views. The official ATO calculator doesn’t handle long service leave; the Fair Work calculator doesn’t handle PAYG withholding. WorkCalc lets you cross-check one thing against another from the same site.
• Forward-looking. The official calculators sometimes lag legislative changes by months. WorkCalc’s PAYG calculator was updated for FY 2026-27 before the official ATO calculator confirmed the bracket changes.

For binding outcomes — disputes, tax assessment, formal entitlement claims — always use the official tools. WorkCalc is for understanding, planning, checking and verifying.
