What is Floating Mortgage Interest?

Floating mortgage interest is a type of interest that is not fixed. This means that interest rates can rise or fall according to the Bank Indonesia interest rate reference (BI rate) or internal bank policies. So, your installments can change every certain period, usually every 3, 6, or 12 months.

In contrast to fixed interest, where installments are fixed for a certain period, floating interest is floating or adjusts to economic conditions. That’s why floating interest is a term that is often associated with the risk of installment fluctuations, but it can also be an opportunity if the benchmark interest rate is falling.

Example: You take out a mortgage with a fixed interest rate of 5% for the first 2 years. After that period expires, the interest changes to floating according to the BI rate. If the BI rate goes down, your installments can go down too. But if the BI rate rises, installments can also rise.

Difference between Fixed Rate and Floating Rate

Before going into how to calculate floating interest, it is important to first understand the differences between these two types of interest:

Types of Flowers	Characteristics	Suitable for
Fixed Rates (Fixed)	Fixed installments over a certain period (1-5 years)	You who want budget stability and predictability
Floating Rate (Floating)	Installments can go up and down according to the reference interest rate	Those of you who are ready to be flexible and want the opportunity for interest rates to decrease

Most banks in Indonesia offer a combination: a fixed rate period at the beginning, then a floating mortgage interest rate for the remainder of the term. For example: fixed for the first 3 years, then floating until paid off.

How Floating Mortgage Interest Works

Mechanistically, floating mortgage interest follows the basic effective interest formula: interest is calculated based on the remaining unpaid principal. When interest rates change, the bank will recalculate the installments according to the new interest rate.

For example:

• Floating interest rate = BI Rate + bank margin (eg 2%)
• If the BI Rate is 6%, then the floating interest will be 8%.
  If next month the BI Rate rises to 7%, the floating interest will automatically become 9%.

Usually, this adjustment is made every 3-6 months, depending on bank policy.

How to Calculate Floating Mortgage Interest

When considering applying for a mortgage, how to calculate floating interest is one of the important questions to understand the impact on installments?

Steps to calculate floating interest:

1. Find out the remaining principal on the loan. For example IDR 600 million.

• Loan principal: IDR 600,000,000
• Tenor: 10 years (120 months)
• Floating interest: 7% per year

The calculation:

• Interest per month = (600,000,000 × 7%) ÷ 12 = IDR 3,500,000
• Monthly principal installments = 600,000,000 ÷ 120 = IDR 5,000,000
• Total first month installments = IDR 8,500,000

If the following month the interest rate increases to 9%, then the monthly interest changes to (600,000,000 × 9%) ÷ 12 = IDR 4,500,000. Your installments automatically increase to around IDR 9,500,000 per month.
