SCHADS Underpayment Risk Calculator
Most SCHADS underpayment isn't a payroll officer mistyping a rate — it's four systematic patterns repeating quietly every pay run: missed broken shift allowances, unpaid sleepover disturbances, short shifts paid below the minimum payment, and workers sitting a pay point behind their anniversary. This calculator prices those patterns for your workforce at the 1 July 2026 award rates. Every assumption is adjustable, and the formulas are shown in full below.

Estimate Your Annual Exposure
Your workforce
Default: SACS Level 2.1 from 1 Jul 2026
Error-rate assumptions (defaults reflect patterns we commonly detect — adjust to your view)
Estimated annual underpayment exposure
If the same patterns ran for the full 6-year claim period:
| Missed broken shift allowances | |
| Unpaid sleepover disturbances (1h OT minimum each) | |
| Minimum payment shortfalls (avg 1h at ordinary rate) | |
| Pay point progression lag (one step, ordinary hours) |

How the Estimate Is Calculated
Nothing is hidden — the four components, each priced with figures from the FWO Pay Guide effective 1 July 2026:
- Missed broken shift allowances = annual shifts × % broken days × % missing the allowance × $21.81 (clause 25.6 / 20.12(a); the 2-break allowance of $28.87 would increase this).
- Unpaid sleepover disturbances = sleepover nights per year × % with an unpaid disturbance × your hourly rate × 150% — the clause 25.7(e) minimum of 1 hour at overtime rates, counting a single disturbance per affected night. Multiple disturbances each attract their own hour, so this is conservative.
- Minimum payment shortfalls = annual shifts × % under-paid × 1 hour at the ordinary rate — a conservative average gap for short engagements paid as worked instead of at the clause 10.5 minimum (2 or 3 hours by stream).
- Pay point lag = workers behind × $1.14/hour (the SACS Level 2.1 → 2.2 step at 1 July 2026 rates) × 38 hours × 52 weeks — ordinary hours only; penalties and overtime on the same gap would add 20–40%.
Why These Four Patterns
They're the systematic failures we detect most when auditing real provider timesheets — errors baked into payroll configuration or rostering practice that repeat every cycle rather than one-off mistakes: the broken shift allowance simply not configured, sleepover wake-ups never making it from the progress notes to payroll, short community visits paid as worked, and anniversaries nobody tracks. Deep dives on each: broken shift allowance, sleepover rules, minimum engagement, pay point progression.
From Estimate to Evidence
This calculator prices assumptions. Your timesheets contain the facts. CrossVault's Timesheet Validator runs every shift through the actual SCHADS rules — the four patterns above plus the loading, overtime, cancellation and classification checks this model omits — and prices each gap it finds against the current pay guide. Upload one real pay period and you'll have an evidence-based number instead of an estimate, typically in minutes. That's also exactly the self-audit regulators respond well to — see how to prepare for a SCHADS payroll audit.
Common Questions
Frequently Asked Questions
- How accurate is this underpayment estimate?
- It's a transparent model, not an audit: your workforce inputs multiplied by adjustable error-rate assumptions, priced at the 1 July 2026 award figures. The default assumptions reflect patterns commonly seen in provider timesheets, and the model deliberately omits several error types, so real audited exposure is often higher. For an evidence-based number, audit actual timesheets.
- Why does the calculator multiply the annual figure by six?
- Underpayment claims under the Fair Work Act can reach back up to 6 years, and systematic payroll errors typically run unchanged until found. If a misconfiguration has existed for the full period, the accumulated exposure approaches six times the annual figure — before interest, penalties or superannuation shortfalls.
- What are the biggest sources of SCHADS underpayment?
- In our timesheet audits: missed broken shift allowances, minimum payments not applied to short engagements, unpaid sleepover disturbances, whole-shift loadings paid partially, wrong overtime bands by stream, and classification or pay point errors. The calculator prices the four most quantifiable; the others add to real exposure.
- Does underpayment also create a superannuation problem?
- Usually yes. Underpaid wages generally mean under-contributed super on the same amounts — and under payday super (from 1 July 2026), each affected pay run is a separate SG shortfall accruing daily notional earnings plus an administrative uplift of up to 60% if not remedied.
