A guide to How Much Mortgage Can I Afford in 2026? A Step-by-Step Calculator Guide
As Xskape Finance shifts from over 17 years of word-of-mouth excellence to a bold digital expansion with our refreshed website at www.xskape.com.au, YouTube channel (@xskapebreakout), and X account (@Xskapefinance), we're dedicated to providing Aussies with clear, actionable tools for smarter home buying. With the RBA cash rate holding steady at 3.6% as of late 2025 and forecasts pointing to potential rises to around 3.85% or even 4.1% by end-2026, affordability is more crucial than ever. Rising property prices and living costs mean knowing your borrowing power upfront avoids heartbreak. In this guide, we'll walk through a step-by-step process to calculate what you can afford, factoring in income, debts, RBA-influenced interest rates, and stamp duty. Plus, we'll include a simple embedded calculator example to get you started.
Step 1: Start with Your Income ✅
Your gross annual income is the foundation of affordability. Lenders typically allow 30-40% of your after-tax income for mortgage repayments, but this varies by bank. Include salary, bonuses, and any partner’s income if applying jointly. For example, on a $100,000 single income, you might afford repayments up to $3,000 monthly after taxes and buffers. Pro Tip: Use verifiable income only—lenders stress-test at higher rates (e.g., +3% buffer) to ensure you can handle 2026 hikes.
Step 2: Subtract Debts and Living Expenses ✅
Deduct ongoing debts like credit cards, car loans, or HECS from your income. Lenders use a debt-to-income (DTI) ratio under 6x, plus a living expense buffer (around $5,000-$10,000 annually per household). Track expenses via apps to get accurate figures—don't underestimate! Pro Tip: Pay down high-interest debts first to boost your borrowing power; at Xskape, we review this in free consultations.
Step 3: Factor in RBA Rates and Interest ✅
The RBA's cash rate directly impacts mortgage rates—expect variable rates around 5-6% in 2026 based on forecasts. Use a 3% assessment buffer for stress-testing. Formula: Max borrowing = (Affordable monthly repayment) / (Monthly interest factor for 30-year loan). Pro Tip: Lock in fixed rates if hikes loom—our brokers at Xskape access competitive options from 30+ lenders.
Step 4: Add Stamp Duty and Other Upfront Costs ✅
Stamp duty varies by state and property value—no changes announced for 2026, so use 2025 rates: e.g., NSW ~$28,000 on $800,000 home; VIC ~$40,000; QLD lower at ~$15,000. Factor in 5-10% deposit, LMI if under 20%, and fees (~$5,000). First-home buyers may get concessions. Pro Tip: Use state revenue office calculators for exacts—pair with schemes like the First Home Guarantee to minimize.
Putting It All Together: Your Affordability Calculator ✅
Here's a simplified embedded tool example (adapt with your numbers; for precision, use our interactive version at www.xskape.com.au). Assume $100k income, $500/month debts, 5.5% rate, 30-year term:
Net monthly income: ~$6,000 (after tax).
Affordable repayment: 35% = $2,100.
Max loan: ~$450,000 (using repayment formula).
Add stamp duty (e.g., NSW $20,000 for $600k home) + deposit (10% = $60,000). Total afford: ~$600k property. Adjust for 2026 rates—try it now!
