First Home Guarantee Calculator: Your Complete 2025-26 Guide to Buying with 5% Deposit

Dreaming of owning your first home but struggling to save a 20% deposit? You're not alone. With Australian property prices continuing to rise, saving $100,000 or more for a deposit can feel impossible, especially while paying rent and managing everyday living expenses. The good news is that the Australian government's First Home Guarantee scheme could help you enter the property market much sooner than you think. This initiative allows eligible first home buyers to purchase a property with just a 5% deposit, without paying thousands in Lenders Mortgage Insurance (LMI). Whether you're a young professional saving for your first apartment, a couple planning to start a family, or someone who's been renting for years waiting for the right opportunity, understanding how the First Home Guarantee works could be the key to making your home ownership dreams a reality.

What Is the First Home Guarantee and How Does It Work?

The First Home Guarantee (FHG), previously known as the First Home Loan Deposit Scheme, is an Australian government initiative designed to help eligible first home buyers purchase a home sooner by reducing the deposit required to avoid Lenders Mortgage Insurance. Under normal circumstances, lenders typically require borrowers to have a 20% deposit to avoid paying LMI, which protects the lender if you default on your loan. Without this guarantee, buyers with smaller deposits face additional costs that can add thousands of dollars to their loan.

Under the First Home Guarantee, the federal government acts as a guarantor for up to 15% of your property's value. This means you can secure a home loan with just a 5% deposit while the government guarantees the remaining portion needed to reach that 20% threshold. The guarantee is not a cash payment or deposit contribution — it's a legal arrangement between the government and your lender that eliminates the need for LMI. This can save you anywhere from $10,000 to $30,000 depending on your property value and loan amount.

The scheme is administered by the National Housing Finance and Investment Corporation (NHFIC) and is available through participating lenders across Australia. There are 35,000 places available each financial year, allocated on a first-come, first-served basis. Once approved, you have 90 days to find and purchase a suitable property. The guarantee remains in place until you've paid down your loan to reach 20% equity, you refinance your loan, or you sell the property.

First Home Guarantee Eligibility: Do You Qualify in FY 2025-26?

To access the First Home Guarantee, you need to meet several eligibility criteria. First, you must be an Australian citizen at least 18 years old. Permanent residents are not eligible for this scheme. You must also be a genuine first home buyer, meaning you cannot have previously owned or held an interest in residential property in Australia. This includes any property held anywhere in the country, regardless of whether you lived in it or held it as an investment.

Your income must fall within specific thresholds to qualify. For individual applicants, your taxable income for the previous financial year must not exceed $125,000. For couples applying together, your combined taxable income must not exceed $200,000. These thresholds are assessed using your most recent Notice of Assessment from the Australian Taxation Office. If your income fluctuates, it's important to calculate your Take-Home Pay accurately and understand how much Income Tax you pay to ensure you meet these requirements for FY 2025-26.

Additionally, you must intend to occupy the property as your principal place of residence. This means you cannot use the First Home Guarantee to purchase an investment property. You must move into the home within 12 months of settlement and live there continuously for at least 6 months. The scheme is limited to one guarantee per applicant, and you cannot have previously received assistance under similar government housing schemes.

Property Price Caps: What Can You Afford in FY 2025-26?

The First Home Guarantee applies to properties valued up to certain price caps, which vary depending on where you're buying. These caps reflect the different property markets across Australia's states and territories and are reviewed regularly to remain relevant. Understanding these limits is crucial when using a first home guarantee calculator to determine your eligibility and budget.

For the 2025-26 financial year, the property price thresholds for the First Home Guarantee are as follows. Note that these caps differ slightly from other government schemes like the Family Home Guarantee, so it's important to check the correct figures for your situation:

Note: Price caps are current for FY 2025-26. Regional centres include Newcastle, Lake Macquarie, Illawarra, Geelong, Gold Coast, and Sunshine Coast. Always verify current thresholds with the National Housing Finance and Investment Corporation (NHFIC) before applying.

Calculating Your Savings: A Real-World Example

Let's look at a practical example to see how the First Home Guarantee could work for you. Imagine you're a first home buyer in Melbourne earning $95,000 per year, and you've managed to save $40,000 for a deposit. You want to purchase a $750,000 apartment in the city. Under normal lending criteria, you would need a $150,000 deposit (20%) to avoid LMI, leaving you $110,000 short. Alternatively, you could proceed with a smaller deposit and pay LMI, which on a $710,000 loan could cost approximately $15,000 to $18,000.

With the First Home Guarantee, your $40,000 deposit represents 5.3% of the purchase price, meeting the minimum 5% requirement. The government guarantees the remaining 14.7% to your lender, allowing you to borrow $710,000 without paying a cent in LMI. That $15,000 to $18,000 saving stays in your pocket, or can be put toward your deposit to reduce your loan amount.

Now consider your ongoing financial position. With a $95,000 salary for FY 2025-26, you'll pay approximately $21,500 in Income Tax plus the 2% Medicare Levy, bringing your total tax liability to around $23,400. Your annual take-home pay is roughly $71,600, or about $5,970 per month. If you have HECS-HELP student debt, compulsory repayments will be calculated based on your income threshold. Use our comprehensive calculators to understand exactly how much you can afford to borrow based on your true after-tax income.

Comparing First Home Guarantee with Other Government Schemes

Australia offers several government schemes to help people enter the property market, and understanding the differences can help you choose the best option. The Family Home Guarantee is specifically designed for eligible single parents with dependent children, allowing purchase with just a 2% deposit. If you're a single parent, you may qualify for this more generous scheme instead of the standard First Home Guarantee.

The Regional First Home Buyer Guarantee supports eligible first home buyers purchasing in regional areas, also with a 5% deposit. This scheme has specific location requirements outside major capital cities and is designed to encourage home ownership in regional Australia. The property price caps for this scheme may differ from the standard First Home Guarantee, potentially allowing you to purchase higher-priced properties in certain regional locations.

You may also be eligible for state-based First Home Owner Grants and stamp duty concessions in addition to the First Home Guarantee. These are separate programs administered by state and territory governments that can provide significant additional financial support. In some states, you could receive a $10,000 to $30,000 grant plus stamp duty exemptions on top of accessing the 5% deposit guarantee. The combination of federal and state assistance can dramatically reduce the cash you need upfront.

Important Considerations Before Applying

While the First Home Guarantee makes home ownership more accessible, it's essential to understand the long-term implications. Buying with a 5% deposit means you're borrowing 95% of your property's value, resulting in higher mortgage repayments compared to someone with a larger deposit. You'll also pay more interest over the life of the loan because you're starting with a larger principal amount. Before committing, use our Take-Home Pay Calculator to ensure your after-tax income can comfortably cover these higher repayments.

Interest rate changes can significantly impact your budget when you have a high loan-to-value ratio. A 1% increase in interest rates could add hundreds of dollars to your monthly repayments. Building an emergency fund becomes even more critical when you have minimal equity in your home. Additionally, consider how your Superannuation balance may be affected if you reduce contributions to focus on mortgage repayments. Some buyers explore Salary Sacrifice arrangements to boost savings while maintaining super contributions.

The First Home Guarantee places are limited to 35,000 per financial year and are allocated quickly. It's important to have your finances in order, including pre-approval from a participating lender, before places are released. You'll also need to factor in other purchase costs such as stamp duty, conveyancing fees, building inspections, and moving expenses, which can add $10,000 to $20,000 to your upfront costs.
