How to Use the PropertyID Mortgage Calculator
The PropertyID Mortgage Calculator helps you instantly estimate your monthly home loan payments in Indonesia. Follow these simple steps:
- Property Price: Input the estimated price of the house or apartment you plan to purchase.
- Down Payment (DP): Choose the down payment percentage you plan to pay (average minimum of 10% - 20% in Indonesia). The DP rupiah value will be automatically calculated.
- Interest Rate: Enter the annual interest rate offered by your bank (e.g., 6.5%).
- Loan Term (Tenor): Select your desired loan term (ranging from 5 to 30 years).
Once you input these parameters, the tool will instantly display your monthly installment estimation, loan principal, total interest paid, amortization schedule, and compare alternative loan term scenarios.
How to Calculate Mortgage Payments Manually
Most banks in Indonesia apply the annuity or effective interest rate method, where the interest portion decreases and the principal portion increases over time. The monthly payment formula is:
Where:
- P (Principal): The loan principal (Property Price minus Down Payment).
- r (Rate): Monthly interest rate (Annual interest rate divided by 12 months, e.g., 6% / 12 = 0.005).
- n (Period): Total number of monthly payments (Term in years multiplied by 12, e.g., 15 years × 12 = 180 months).

Additional Costs When Buying a House via Mortgage
Home buyers should note that buying a house involves extra transaction fees. These extra fees can total around 5% to 10% of the property value:
- BPHTB (Land and Building Acquisition Tax): A buyer tax calculated as 5% of the transaction value minus the non-taxable limit (NPOPTKP).
- AJB (Deed of Sale and Purchase) & Title Transfer (BBN) Fees: Fees paid to the Land Deed Officer (PPAT) to process the transfer of ownership (usually 1% - 2% of the property price).
- Bank Provision & Admin Fees: Bank fees for mortgage processing, typically 1% of the approved loan principal.
- Insurance Fees: Includes mortgage life insurance (protects the bank if the borrower passes away) and fire insurance (protects the building itself).
Understanding Mortgage Interest Rates: Fixed vs Floating
Mortgages in Indonesia typically offer a combination of two types of interest rates:
- Fixed Interest Rate: An interest rate that remains constant for a set period (e.g., fixed for the first 3 years). The main advantage is that your monthly payments remain stable and are unaffected by market interest rate hikes.
- Floating Interest Rate: An interest rate that fluctuates based on the central bank's benchmark rate (BI-Rate) and market conditions. After the fixed term ends, your mortgage interest switches to a floating rate, which typically ranges from 10% to 14% per year in Indonesia, meaning your monthly payments could rise significantly.
