NDIS SIL Calculator 2025-26
Estimate Supported Independent Living (SIL) annual and weekly costs from your support ratio, intensity, daytime active hours, and overnight type. Figures use 2025-26 NDIS price limits as a planning guide—your provider's SIL quote and the NDIA determine approved funding.

How to use this calculator
- 1. Set your support ratio (1:1, 1:2, or 1:3) and standard vs high-intensity rates.
- 2. Slide active daytime hours (6am–10pm) and choose overnight: none, sleepover, or active night.
- 3. Tap Calculate SIL costs to see estimated weekly, daily, and annual totals plus a simple breakdown.
SIL vs rent and living costs
SIL pays for support workers in shared living—not the building.
Rent and day-to-day living are usually paid from your income (e.g. DSP), not from SIL line items.
This tool does not include rent, groceries, or utilities.
Disclaimer: Estimates only. Approved SIL funding comes from a formal provider quote and NDIA decision. Provider charges and rosters vary.

Note: This is an estimate only. Actual SIL funding is determined through a formal quote process between your provider and the NDIA. Costs may vary based on individual circumstances and provider charges.
Supported Independent Living in plain English
SIL is NDIS funding for the people who support you in shared accommodation—help with daily living, personal care, and supervision as set out in your roster of care. It does not pay for the rent or purchase of the home itself (that is separate, and often where SDA or private rent fits in).
Funding levels depend on how much support you need across the week, including overnights. Higher ratios of staff to participants (for example 1:1) and active night shifts usually cost more than shared 1:3 supports with a sleepover model.
How this calculator models your week
The tool uses a simplified week: weekday hours at the weekday limit, Saturday at evening/Saturday rates, Sunday at Sunday rates, and your chosen overnight option applied across seven nights, with hours and nightly costs divided by your support ratio (your share of the worker's time).
Real rosters include public holidays, leave, different shift patterns, and mixed ratios—so treat the output as a ballpark for conversations with a SIL provider, not a plan budget line copied from the NDIA.
Quotes, plans, and the NDIA
Before SIL appears in your plan, a registered provider typically completes an assessment and submits a SIL quote. The NDIA decides what is reasonable and necessary against your goals and evidence. That process can take months and may differ from any online estimate.
Your support coordinator or LAC can help you compare houses, providers, and roster options while funding is being determined.
Rent, living costs, and what SIL does not cover
Participants usually pay reasonable rent contribution and ordinary living costs (food, utilities, personal items) from their own income, such as DSP. SIL line items are for support delivery, not those household bills—always read your service agreement and occupancy terms carefully.
Frequently Asked Questions
NDIS SIL funding varies significantly based on your individual support needs:
- Lower needs (1:3 ratio, sleepover): ~$150,000 - $200,000/year
- Medium needs (1:2 ratio, sleepover): ~$200,000 - $300,000/year
- Higher needs (1:1 ratio, active night): ~$350,000 - $450,000+/year
The NDIA determines your funding based on a SIL quote submitted by your provider, which details your specific support roster and needs.
Supported Independent Living (SIL) costs depend on several factors:
- Support ratio: 1:1 (most expensive) vs shared 1:2 or 1:3
- Overnight support: Active night (~$680/night) vs sleepover (~$283/night)
- Support intensity: Standard vs high-intensity rates
- Hours of support: 24/7 vs daytime only
SIL funding covers support workers only. You'll pay rent and living expenses separately from your personal income (typically DSP).
The 2025-26 NDIS SIL price limits are:
| Support Type | Standard | High Intensity |
|---|---|---|
| Weekday (6am-8pm) | $70.88/hr | $78.80/hr |
| Evening/Saturday | $78.23/hr | $86.37/hr |
| Sunday | $100.17/hr | $110.59/hr |
| Public Holiday | $128.11/hr | $141.38/hr |
| Sleepover | $282.78/night | |
| Active Night | $85.22/hr | $94.47/hr |
The SIL application process:
- Discuss with your Support Coordinator or LAC - they'll help determine if SIL is right for you
- Choose a SIL provider - research providers and visit potential houses
- Provider assessment - they'll assess your support needs
- SIL quote submission - the provider creates a detailed roster and submits to NDIA
- NDIA review - may take several weeks to months
- Funding added to plan - once approved, SIL is added to your NDIS plan
The whole process can take 3-6+ months, so start early.
SIL and SDA are separate but often used together:
| SIL | SDA | |
|---|---|---|
| What is it? | Funding for support workers | Funding for the building |
| Pays for | Staff to help with daily living | Specialized accessible housing |
| Where | Any shared living arrangement | Purpose-built disability accommodation |
| Eligibility | Need 24/7 or significant support | Extreme functional impairment |
You can have:
- SIL only (in regular housing)
- SIL + SDA (in specialist housing)
- SDA only (if you need the building but not 24/7 support)
