If you are planning to buy a property in Singapore, a mortgage calculator can help you make more informed decisions during the loan process.
Firstly, a mortgage calculator can help you quickly estimate your monthly repayment amount. Based on different loan amounts, interest rates, and loan tenures, the calculator will provide a clear repayment schedule, helping you foresee the impact of the mortgage on your financial situation.
Secondly, a mortgage calculator can simulate different loan scenarios, such as adjusting the down payment percentage or loan tenure. This allows you to visually see how these changes affect the repayment amount and mortgage interest, enabling you to choose the most suitable loan package based on your financial situation and future plans.
Additionally, a mortgage calculator can help you compare loan products from different banks or financial institutions to find the most favorable and suitable package for yourself.
In summary, a mortgage calculator not only saves a significant amount of time but also reduces uncertainty in mortgage decisions, helping you manage your finances better.

Mortgage Monthly Repayment Mechanism
Most people apply for a mortgage from a bank or the Housing & Development Board (HDB) when purchasing a property. Homebuyers need to make monthly repayments on their home loan within a specified period until the principal and interest are fully paid off. This is the mortgage monthly repayment mechanism.
As long as the applicant makes timely payments each month, the mortgage balance will decrease. Generally, the loan tenure depends on the borrower’s age—the younger the borrower, the longer the loan tenure they can obtain.
The maximum loan tenures available for different property types and loan types are as follows.
| Property Type | Loan Type | Maximum Loan Tenure |
| HDB Flat | HDB Loan | 25 years |
| HDB Flat | Bank Loan | 30 years |
| Private Property or EC | Bank Loan | 35 years |
Whether you choose an HDB loan or a bank loan depends entirely on the homebuyer’s individual needs. Since everyone’s situation is unique, if you have any questions about choosing a loan, feel free to contact our mortgage specialists. We can conduct a detailed assessment of your personal circumstances and provide personalized advice.
How a Mortgage Calculator Works
A mortgage calculator calculates your monthly home loan repayment amount based on the borrowed sum and computes the corresponding interest based on the outstanding loan balance.

What is the Maximum Mortgage Loan Amount?
The maximum home loan amount will be determined by the lending institution, which could be the HDB, banks, or other financial institutions.
The maximum loan amount is also subject to the Loan-to-Value (LTV) ratio and the Total Debt Servicing Ratio (TDSR) limits.
As of 2025, Singapore’s latest LTV limit is 75%, and the TDSR limit is 55%.
This means that for a property valued at S$1 million, the loan amount cannot exceed S$750,000. If your monthly income is S$10,000, your total monthly debt repayments cannot exceed S$5,500.
Can the Mortgage Repayment Period be Changed?
If you have a loan from a bank or another financial institution, you may be able to extend the repayment period.
However, if you choose to make an early full or partial repayment, you will typically need to pay a penalty (prepayment fee), which ranges from 0.75% to 1.50% of the repaid amount.
