Casual Loading Calculator

Calculate casual loading — Australia's 25% premium for casual work: your loaded rate, the annual value of what the loading replaces, and the casual-vs-permanent break-even.
Quick answer: Casual rate = permanent base rate × 1.25. A $30/hour permanent-equivalent role pays casuals $37.50/hour. The 25% buys out paid leave, sick pay, notice, and redundancy — whether that trade wins depends on how much leave you'd actually use.
What the 25% Buys Out
| Entitlement casuals give up | Approx. value (% of pay) |
|---|---|
| 4 weeks annual leave + 17.5% loading | ~9% |
| 10 days personal/carer's leave | ~4% |
| Public holidays (paid without working) | ~3% |
| Notice of termination + redundancy scale | ~2-4% (tenure-dependent) |
| Job security / predictable rostering | Unpriced |
| Total replaced | ~18-20% + security |
The arithmetic verdict: 25% roughly compensates IF you never get sick beyond the average and value flexibility — young healthy workers often come out ahead in cash; anyone using real sick leave or valuing stability usually doesn't.
Worked Examples
Example 1 — the loaded rate. $30 base: casual = $37.50/hour; 38 hours = $1,425/week vs $1,140 permanent — $285/week more cash, zero paid leave.
Example 2 — the annual truth. Permanent at $1,140/wk works ~46 weeks for 52 weeks of pay ($59,280 + security). Casual at $1,425 × 46 actual working weeks (taking the same 4 weeks off + 10 sick days unpaid) = $60,990 — a slim $1,700 edge that one bad flu season erases.
Example 3 — loading on penalties. Award-dependent: some apply 25% to the base THEN penalties (compounding), others add them separately. Saturday 150% + casual loading can be 175% of base or 187.5% — your award's clause decides; the gap is real money.
Casual Conversion Rights
After 6 months (12 in small business) of regular patterns, casuals can notify for conversion to permanent — the "employee choice" pathway under the Closing Loopholes rules. Employers may refuse only on fair, reasoned grounds. Convert and you trade the loading for the entitlement stack — run this calculator's comparison before choosing; the right answer differs by life stage.
Common Underpayment Patterns
- Flat rates "including loading" that don't reach award base × 1.25 across all hours worked — compare your flat rate against the loaded award rate for YOUR classification and times.
- Loading skipped on overtime/penalty shifts where the award says it compounds.
- Perma-casuals without super on all OTE — the 12% super guarantee applies to casual ordinary-time earnings from dollar one.
- Six-year back-claims on loading gaps are standard Fair Work Ombudsman territory.
For Employers
Casual flexibility costs 25% + admin + conversion-rights management. The honest planning rate for a casual seat: loaded rate × hours + super + workers comp ≈ 1.4x the permanent base wage bill for the same hours — worth it for genuine variability, expensive as a permanent-workforce substitute (which the conversion rules now actively unwind).
Frequently Asked Questions
What is casual loading in Australia?
A 25% premium on the base rate compensating casuals for forgone paid leave, sick pay, notice, and redundancy — $30 base becomes $37.50 casual.
Does casual loading apply to penalty rates?
Award-dependent — some compound (base × 1.25 × penalty), others add the loading separately. The difference on a Sunday shift is significant; check your award's method.
Is casual work worth 25% more?
The forgone entitlements are worth ~18-20% plus security — healthy workers wanting flexibility come out slightly ahead in cash; anyone using real sick leave usually falls behind.
Can casuals become permanent?
Yes — after 6 months of regular patterns (12 in small businesses), the employee-choice conversion pathway applies; employers need fair grounds to refuse.
Do casuals get superannuation?
Yes — the full super guarantee on ordinary-time earnings from the first dollar; skipping it is a top FWO finding.
Do casuals get paid public holidays?
Not when not working them — but working one attracts the award's public-holiday penalty, typically with the loading interaction on top.
