Mortgage calculator: instalment and APR

Calculate the monthly instalment, effective rate and costs of a property loan with your own interest rate — non-binding and without contact details.

Calculate a property loan: instalment, effective rate and costs

The calculator follows the method Austrian credit intermediaries use for model calculations: purchase costs, the bank's and land register's fees financed with the loan, the monthly instalment as an annuity and the effective rate under the Mortgage and Real Estate Credit Act (HIKrG). You enter the interest rate yourself — the one from your offer.

How it is calculated: Net loan amount = purchase price + purchase costs − own funds. Added to this are the mortgage registration (1.2% of the mortgage amount: loan plus 20% security for ancillary costs), the processing fee, the filing fee and the certification of signatures. The monthly instalment is an annuity on this amount plus account fees; the effective rate is the annual rate at which all instalments together equal exactly the loan amount paid out.

Example: Loan €237,000.00, 30 years, nominal rate 3.375% variable: loan including fees €248,271.89, monthly instalment €1,102.69, effective rate 3.854 %, total €396,968.40.
