How your mortgage repayments are calculated
We use an amortisation calculator to estimate your monthly payments and show how your loan is repaid over time. While payments remain the same, the portion going to principal increases over time until the loan is fully repaid.
Our mortgage calculator highlights the first 5 years, as most borrowers review or refinance their home loan within this period.
Your monthly repayment is calculated based on:
- Loan amount (how much you borrow)
- Interest rate (cost of borrowing)
- Loan tenure (repayment period)
Property loans in Singapore use amortisation, where monthly payments are fixed and a larger portion goes to interest at the start. As time passes and more payments are made, more will go towards your principal.
Even small changes in interest rates or tenure can significantly affect your monthly payment and total interest paid.
Our mortgage calculator can help you stress-test your finances by modelling different interest rate scenarios.
See how changes in rates can affect your monthly repayments and affordability, helping you plan for unexpected scenarios.
Factors That Affect Your Home Loan Repayments
Several factors can significantly impact your monthly mortgage repayments in Singapore.
Interest Rate
Even a small difference in interest rates can substantially affect the total amount paid throughout your mortgage.
Loan tenure
Longer loan tenures reduce monthly repayments but generally increase the total interest paid over the life of the loan.
Loan amount
The larger your borrowing amount, the higher your monthly repayment obligations.
Loan-to-Value (LTV)
Your LTV ratio determines how much you can borrow, up to 75% for most properties in Singapore.
Fixed vs Floating Rates
Fixed-rate mortgages offer repayment stability, while floating-rate loans may fluctuate according to market conditions such as SORA.
Why do we calculate only five years?
Most mortgage loan packages in Singapore have lock-in or fixed-rate periods of up to 5 years. Many homeowners review or refinance their loan during or after this period to secure better rates.

How Much Can You Afford?
Before applying for a mortgage loan in Singapore, it's important to understand your borrowing capacity. While monthly repayment estimates are useful, banks also evaluate your financial profile based on regulatory requirements.
Total Debt Servicing Ratio (TDSR)
The Total Debt Servicing Ratio (TDSR) limits the proportion of your gross monthly income that can be used to service all outstanding debt obligations, including your home loan.
Mortgage Servicing Ratio (MSR)
For eligible HDB flats and Executive Condominiums, the Mortgage Servicing Ratio (MSR) limits the proportion of income that can be allocated specifically to mortgage repayments.
Income Requirements
Banks assess your income, employment stability, existing financial commitments, and credit profile when determining your maximum borrowing capacity.
Loan Eligibility
Your eligibility may also depend on:
- Age
- Citizenship or residency
- Property type
- Outstanding loans
- Loan tenure
- Credit assessment
Knowing these factors is crucial when estimating how much you can comfortably borrow before applying for financing.
