Mortgage Calculator Austria: How Much Can You Borrow Based on Your Salary?

Mortgage Calculator: How Much Mortgage Can I Get with My Salary in Austria?

"How much mortgage can I get with my salary?" — this is the first question almost everyone asks before even starting to look for a property. The answer depends on more than just your salary. This article explains the exact calculation, provides concrete tables for various income situations, and shows what you can do to increase your maximum loan amount when looking for a property loan Austria.

The Short Answer — and Why It's Never Enough

As a general rule of thumb in Austria, with a monthly net income of X Euros, you can typically get a mortgage of approximately 80 to 100 times that amount.

For example, with a net income of 3,000 Euros, this would mean a loan of 240,000 to 300,000 Euros.

However, this rule of thumb is so broad that it can be misleading in many cases, as it doesn't account for equity, existing financial obligations, or the current interest rate situation. The real answer is more individual and yet more predictable than the rule of thumb suggests. Before committing, you should start a detailed mortgage comparison.

How Banks Calculate Your Mortgage Eligibility in Austria

Austrian banks follow a structured assessment process for granting loans. At its core, it's about one question: Can this household reliably pay the monthly loan installment, even if circumstances change?

The key instrument for this is the Debt Service Ratio — the relationship between your monthly loan burden and your monthly net income.

The Debt Service Ratio — The Central Calculation Principle for Your Expat Mortgage

Formula:
Maximum monthly loan installment = Net income × Debt Service Ratio

Most Austrian banks internally adhere to a Debt Service Ratio of 35 to 40 percent of monthly net income. While the KIM-Verordnung (Credit Institution Mortgage Ordinance) expired in October 2025, this remains a practical internal guideline for banks. This is crucial for expats seeking a mortgage Austria.

Important: The Debt Service Ratio applies to the total of all monthly credit obligations — not just your new home loan. If you already have a car loan, consumer credit, or other ongoing installment payments, these must be deducted.

Step-by-Step Calculation of Your Property Financing

• Step 1: Determine your net income

• Step 2: Apply the Debt Service Ratio (e.g., 35%)

• Step 3: Deduct existing monthly obligations

• Step 4: Enter the remaining installment into the loan calculator

• Step 5: Read off the maximum loan amount

Example for Expats Buying Property in Austria:

• Net income: 3,500 Euros

• Maximum total installment (35%): 1,225 Euros

• Current car loan: 250 Euros/month

• Remaining installment for home loan: 975 Euros

• At 3.5% interest rate, 25 years: approx. 194,000 Euros loan

How Existing Credit Obligations Reduce Your Maximum Mortgage in Austria

Basis: 25 years loan term, 3.5% interest rate.

What this table shows: A car loan of 300 Euros per month reduces the possible mortgage for a 4,000 Euro net income by 60,000 Euros. This is equivalent to the purchase price of a small apartment. If you pay off existing loans before applying for a mortgage, you significantly improve your starting position. If you have expensive existing loans, you can check out refinancing options here.

From Loan to Purchase Price — How Much Property Can I Afford in Austria?

The maximum loan amount is not the same as the maximum purchase price. Equity is added to the loan — but your equity must also cover the ancillary purchase costs (Kaufnebenkosten).

The complete calculation:
Maximum Purchase Price = Loan Amount + Equity − Ancillary Purchase Costs (approx. 10%)

Example for Expats:

• Maximum Loan: 280,000 Euros

• Available Equity: 80,000 Euros

• Ancillary Purchase Costs (Kaufnebenkosten) for a purchase price of 350,000 Euros (approx. 10%): 35,000 Euros

• Equity after ancillary costs: 45,000 Euros

• Maximum Purchase Price: 280,000 + 45,000 = 325,000 Euros
