Affordability Calculator · Updated 11 May 2026
Private School Affordability Calculator (Australia 2026)
A blunt, honest tool: enter your after-tax household income + number of school-age children — see which Australian private schools sit comfortably in your budget, which would stretch you, and which are aspirational. Independent education-finance tool, free, no sign-up.
Key takeaways
- Recommended threshold: 25-30% of after-tax household income for one child. 35-45% upper realistic for multiple children.
- Calculator shows which schools fit comfortable / stretched / strained thresholds based on YOUR numbers.
- 108 verified Australian private schools with real 2026 fees. No sign-up, no data collection.
- Boarding adds $25,000-$45,000/year on top of tuition — requires higher income threshold.
- Don\'t sacrifice retirement savings for school fees — super compounds over 30+ years; school fees are 6-13 years.

Caveat: This is a starting framework, not personalised advice. Talk to a financial planner before committing to long-term fees beyond 25-30% threshold.
Schools matching your comfortable budget
How to think about this
The 25-30% rule is a starting point, not a hard line. Some families happily spend 40% of after-tax income on private school for a single child + thrive. Others stretching to 35% experience real financial strain. Key questions:
- Job security: high earner with stable position? You can stretch more. Variable income or recent role? Stay conservative.
- Retirement readiness: on track for super at your age? You have flexibility. Behind on super? Don\'t sacrifice it for school fees.
- Other commitments: mortgage paid off? Significant flexibility. Big mortgage + young family? Stick to 25%.
- Total period: 6 years of private (Year 7-12) is different to 13 years (Prep-Year 12). Plan for the full period.
- Fee growth: 4-5% annual indexation. Year 7 fees of $30k become Year 12 fees of $36-38k. Budget for the high end.
- Hidden costs: uniforms, technology levies, camps, music tuition, sport, building fund. Add $5,000-$15,000/year on top of tuition.
Common questions
What\'s the recommended income threshold for private school fees?
Financial planners typically recommend 25-30% of net household income as the maximum sustainable share for education costs (one child). For multiple children, 35-45% is the upper realistic limit. Above this, families often experience real financial strain — reduced retirement savings, deferred home maintenance, family stress. Some families happily spend higher proportions (40%+ for one child at elite schools), but this requires strong income + low other commitments.
How does this calculator work?
You input household after-tax income + number of school-age children + total annual savings/investments + significant debt commitments. We calculate your "education budget" at three thresholds: comfortable (25%), stretched (30%), and strained (35%). Then we show which annual school fee ranges fit each threshold. Live data from 108 verified Australian private schools.
Why use after-tax income vs gross?
Because school fees are paid from after-tax income. A $200,000 gross income in Australia translates to roughly $148,000 after-tax (single income) or $165,000 (two incomes at $100k each due to lower marginal rates). The after-tax figure is what\'s actually available for spending — including school fees. Using gross income overstates affordability.
Should I include both partners\' incomes?
Yes — total household after-tax income matters. If one partner works full-time + other part-time, include both. If one partner stops work to manage children\'s schedule, use only the working partner\'s income for sustainability assessment. School fees should ideally be sustainable on the most reliable income stream.
What about scholarships + bursaries?
Substantial scholarship reduces the effective fee. Use the NET fee after scholarship in your planning. Bursaries are need-based (means-tested) and can dramatically change affordability for income-constrained families. See our scholarship guide for application pathways. Don\'t assume scholarship — apply + plan based on the unsuccessful scenario.
What about boarding fees?
Boarding adds $25,000-$45,000/year on top of tuition. For boarders, total annual cost is typically $65,000-$95,000/year. The 25-30% household income threshold for boarders typically requires $260,000+ after-tax household income for one child, or higher for multiple children. Boarding scholarships exist at many schools (especially regional) — apply early.
Should I sacrifice retirement savings for private school?
Generally no. Retirement savings compound for 20-40+ years and cannot be replaced once foregone — there\'s no "scholarship" for retirement. School fees are real costs for 6-13 years; missing 5-10 years of super contributions creates a $200,000-$500,000 retirement shortfall over a 30-year career. If choosing between private school + super: discuss with a financial planner first. Often a stretch private school is the wrong trade vs comfortable lifestyle + retirement.
What if our income is irregular (self-employed, commission, business)?
Be conservative. Use 70-80% of your average 3-year income as the "stable" figure. Higher income years can be saved for fee buffer; lower years can be drawn from buffer. Many self-employed families pre-pay 12-18 months of fees during good years. Schools are generally accommodating about timing if you maintain communication.
What about ADF/government employees with rebates?
ADF: Education Assistance Schemes provide up to $4,200/year toward private school fees for ADF families. State/federal public servants: various salary-sacrifice + tax-deductible arrangements exist but cap at a small percentage of fees. Don\'t over-rely on rebates for affordability — most cover 5-15% of fees, not the bulk.
