Use our Singapore Loan Amortisation Calculator to generate a full yearly schedule showing exactly how your monthly payments go towards interest costs and principal reduction throughout your loan tenure.
When you service your mortgage in Singapore, your monthly loan instalment does not reduce your loan balance linearly. In the early years of your loan tenure, a significant portion of every payment goes toward interest. Over time, that balance shifts progressively toward paying down the principal.

Estimate your monthly loan instalment and see how each payment is allocated between principal and interest throughout the loan tenure.

Annual Principal and Interest Allocation Across Loan Tenure
Each row reflects a year of repayments. As the loan nears maturity, a larger portion of each instalment is applied toward reducing the principal balance.
This calculator provides estimates for illustration only and does not constitute a loan offer or financial advice. Check with your lender for actual instalments, interest rates, and loan eligibility.
How to Use the Amortisation Calculator
- Enter Property Price ($): Input the purchase price of the property.
- Enter Down Payment ($): Key in your total down payment (CPF Ordinary Account savings plus cash). The calculator automatically subtracts this to determine your net loan amount.
- Set Interest Rate (% p.a.): Input your prevailing or projected mortgage interest rate.
- Set Loan Tenure: Select the loan duration in years (e.g., 25 or 30 years).
Understanding Your Amortisation Results
Once calculated, review the summary breakdown and schedule:
- Monthly Instalment: Your fixed monthly payment required under an amortising loan structure.
- Total Interest Paid: The total cumulative interest paid over the entire life of the mortgage.
- Total Repayment: The overall amount paid over the tenure (Principal + Total Interest).
- Interest / Principal Ratio: The percentage split between borrowing costs (interest) and asset equity building (principal).
- Annual Allocation Table: A year-by-year table detailing how much of your annual outlay goes toward principal reduction versus interest costs.
Why Understanding Your Amortisation Schedule Matters
1. Front-Loaded Interest Costs
Because Singapore mortgages use an amortising loan structure, your interest cost is calculated on the remaining loan balance. During Years 1 through 5, interest costs are at their highest. Seeing this breakdown helps you evaluate refinancing options or partial capital repayments early in the loan cycle.
2. Planning Refinancing and Lock-In Periods
Most bank loans in Singapore commonly come with a 2- or 3-year lock-in period. By examining your amortisation schedule at Year 3 or Year 5, for example, you can see your exact remaining loan balance when preparing to reprice or refinance to a lower SORA-pegged rate.
3. CPF Capital Repayments vs. Accrued Interest
If you finance your mortgage using your CPF OA, you build up 2.5% annual accrued interest—the interest your CPF money would have earned if left untouched. This amount must be refunded to your CPF account when you sell your home. Balancing how much cash versus CPF you use for mortgage payments helps you minimise this cost and plan for future property goals.
