CCS Calculator Explained — How the Child Care Subsidy Is Worked Out

The Child Care Subsidy calculation involves three variables most parents don't fully understand: your income-based percentage, the hourly rate cap, and the activity test. Here's exactly how it works — with worked examples.

The three variables that determine your CCS

Your out-of-pocket childcare cost after CCS is determined by three things — and understanding all three is essential for accurate budgeting:

Variable 1
Your subsidy %
Set by combined family income. Ranges from 90% (under $83,280) to 0% (above $530,000). This is the percentage applied to the capped fee.
Variable 2
Hourly rate cap
~$12.08/hr for long day care. CCS is only applied to fees up to this cap. Fees above the cap are paid in full — this is the 'gap fee'.
Variable 3
Activity test
Both parents need qualifying activity hours. Zero activity = maximum 24 subsidised hours/fortnight, regardless of income.

Income thresholds and subsidy rates (2025–26)

The following rates apply to your combined family income (both parents' taxable income). The subsidy tapers gradually within each income band.

Combined family incomeCCS rateAt $155/day fee — your daily cost
Up to $83,28090%≈$16/day + gap fee
$83,280 – $133,28090% → 80%≈$16–$24/day + gap fee
$133,280 – $183,28080% → 70%≈$24–$36/day + gap fee
$183,280 – $353,68070% → 50%≈$36–$60/day + gap fee
$353,680 – $530,00050% → 0%≈$60–$121/day + gap fee
Above $530,0000%Full fee ($155+/day)

"Gap fee" refers to fees above the hourly rate cap (~$12.08/hr = $120.80/10hr day), paid in full regardless of subsidy rate. Daily cost estimates assume the centre charges $155/day with a standard 10-hour day.

How to calculate your actual daily out-of-pocket cost

The formula looks complicated — but it's straightforward once you understand the cap:

Step-by-step calculation
1
Identify the hourly rate cap
~$12.08/hr × 10 hours = $120.80/day cap
2
Calculate the gap fee
Daily fee − cap = gap fee (paid in full)
3
Apply your CCS % to the capped amount
(1 − CCS%) × $120.80 = your co-contribution on capped fees
4
Add gap fee + co-contribution
Your total daily out-of-pocket cost

Worked examples at three income levels

Example 1: $90,000 combined income
CCS rate: 88%
Daily fee: $145/day
Gap fee (above cap): $145 − $120.80 = $24.20
Co-contribution (on capped): 12% × $120.80 = $14.50
Daily out-of-pocket: $14.50 + $24.20 = $38.70/day
Weekly: $194/week (5 days) · Annual: $9,300/year
Example 2: $150,000 combined income
CCS rate: 75%
Daily fee: $155/day
Gap fee (above cap): $155 − $120.80 = $34.20
Co-contribution (on capped): 25% × $120.80 = $30.20
Daily out-of-pocket: $30.20 + $34.20 = $64.40/day
Weekly: $322/week (5 days) · Annual: $15,450/year
Example 3: $250,000 combined income
CCS rate: 57%
Daily fee: $175/day
Gap fee (above cap): $175 − $120.80 = $54.20
Co-contribution (on capped): 43% × $120.80 = $51.95
Daily out-of-pocket: $51.95 + $54.20 = $106.15/day
Weekly: $531/week (5 days) · Annual: $25,500/year

These examples show how the gap fee can dominate your out-of-pocket cost at higher-fee centres. Choosing a centre that charges at or near the CCS cap significantly reduces your costs — particularly for families on lower incomes who have a high subsidy rate but still face a large gap fee.

The activity test — hours of qualifying activity

The activity test requires each parent to have a minimum number of hours of qualifying activity per fortnight to access subsidised care beyond the 24-hour cap. Qualifying activities include paid work, study, training, volunteering, and active job seeking.

Each parent's activity hours (fortnightly)Subsidised hours (child, per fortnight)
0 hours (no activity)24 hours/fortnight (about 2.4 days/week)
8–16 hours36 hours/fortnight
17–48 hours72 hours/fortnight
49–100 hours100 hours/fortnight
100+ hoursNo fortnightly hour cap

The activity test applies to the parent with the lower activity hours (the "lower activity" parent). One parent can have high activity hours; the subsidy is capped by the lower parent's hours.

Calculate your actual CCS outcome

The Return to Work Calculator uses this exact methodology. Enter your income, childcare fees, and days per week — it calculates your CCS rate, applies the hourly cap, accounts for the activity test, and shows you your true weekly out-of-pocket cost alongside your net income from returning to work.
