Executive Summary
A mortgage amortization schedule is your roadmap to paying off your home loan, showing monthly breakdowns of principal and interest over the loan tenure. In Singapore, where HDB flats cap at 30 years and private properties at 35 years, understanding this schedule helps you minimize total interest paid—potentially saving hundreds of thousands.
For a S$800,000 HDB flat loan at 2.6% over 25 years, your first payment might be 80% interest, shifting to mostly principal by year 20. Homejourney's tools, like our mortgage calculator, let you simulate this instantly with Singpass integration for accurate CPF data.
This 2026 guide covers calculations, regulations like TDSR and LTV, real examples, and Homejourney-exclusive tips for first-time buyers, upgraders, and investors.
What is a Mortgage Amortization Schedule?
An amortization schedule details how each monthly payment splits between interest (cost of borrowing) and principal (reducing your loan balance). Early payments favor interest; later ones accelerate principal reduction.
In Singapore, this matters due to CPF usage and regulations. The formula is: M = P [r(1+r)^n] / [(1+r)^n - 1], where M is monthly payment, P principal, r monthly rate, n payments.[4]
Key Components
- Principal Reduction: Amount paying down the loan.
- Interest Payment: Bank profit, calculated on remaining balance.
- Balance: Outstanding loan after payment.
- Equity Build-Up: Home value minus balance.
Homejourney verifies these via partner banks like DBS and OCBC for precise schedules.
How Does Amortization Work in Singapore?
Singapore mortgages use fixed or floating rates (mostly SORA-based). Payments are monthly, with CPF Ordinary Account funds auto-deducted up to limits.
Example: S$500,000 loan at 2% over 25 years (300 months). Monthly payment: ~S$2,100. Year 1: ~S$830 interest, S$1,270 principal. By year 20: ~S$150 interest, S$1,950 principal.[2]
Amortization Curve
The curve is front-loaded for interest, back-loaded for principal. Shorter tenures mean faster equity but higher payments.
Singapore Mortgage Regulations Impacting Amortization
Monetary Authority of Singapore (MAS) enforces Total Debt Servicing Ratio (TDSR) at 55% of income and Mortgage Servicing Ratio (MSR) at 30% for HDB. Loan-to-Value (LTV) limits: 75% first-timer (<30 years tenure).[1]
Max tenures: HDB 30 years, private 35 years. Age cap: Loan ends at 65 or 30/35 years, whichever sooner.[1]
These shorten effective amortization, increasing early principal paydown. Check eligibility on Homejourney's bank-rates page.
Calculating Your Amortization Schedule
Use the standard formula or Homejourney's calculator. Inputs: Loan amount, rate, tenure.
Step-by-Step Calculation
- Convert annual rate to monthly: r = annual/12/100.
- Compute payments n = years*12.
- M = P * [r(1+r)^n / ((1+r)^n -1)].[4]
- For each month: Interest = balance * r; Principal = M - interest; New balance = old - principal.

HDB Loans vs Bank Loans: Amortization Differences
HDB loans (2.6% fixed, 90% LTV first-timer) have simpler amortization but no refinancing. Bank loans offer lower initial rates (e.g., 1.48% 1M SORA) but variable.[8]
| Feature | HDB Loan | Bank Loan |
|---|---|---|
| Rate | 2.6% fixed | SORA + spread (1.48-1.56% Mar 2026)[8] |
| Tenure Max | 30 years | 35 years private |
| LTV First | 90% | 75% |
| Amortization Flexibility | Fixed | Refinance possible |
HDB suits stability; banks for optimization. Compare on Homejourney.
Interest Rates and SORA in Amortization
SORA (Singapore Overnight Rate Average) replaced SIBOR. Most banks peg to 1M/3M SORA + 0.6-0.8% spread. As of Mar 2026, rates ~1.48-1.56%.[8]
Floating rates mean variable interest portions in your schedule. Fixed rates lock amortization predictability.

Real Singapore Examples with Tables
Example 1: S$600,000 HDB loan, 2.6%, 25 years. Monthly: S$2,690. Total interest: S$407,000.[1]
| Year | Payment | Interest | Principal | Balance |
|---|---|---|---|---|
| 1 | S$32,280 | S$15,480 | S$16,800 | S$583,200 |
| 10 | S$32,280 | S$10,200 | S$22,080 | S$377,000 |
| 25 | S$32,280 | S$70 | S$32,210 | S$0 |
Example 2: S$1M condo, 1.5% SORA, 30 years. Monthly: S$3,500. Saves S$200k vs 2.6%.[2]

Strategies to Optimize Your Amortization
- Shorten tenure: 20 vs 30 years saves S$145k interest on S$500k loan.[1]
- Extra payments: Target principal to front-load reduction (1-1.5% penalty).[1]
- Recast after lump sum: Lowers monthly payment.
- Refinance to lower rate: Recalculates schedule.
Homejourney's multi-bank application submits to DBS, UOCB, etc., via one form with Singpass.
Refinancing and Amortization Schedules
Refinancing resets amortization. If rates drop 0.5%, save S$50k on 25-year loan. But costs 0.75-1.5% penalty + fees.

Common Pitfalls and How to Avoid Them
- Misunderstanding front-loading: Budget for high early interest.
- Ignoring TDSR: Use Homejourney calculator first.
- Not using CPF optimally: Max OA for interest offset.
- Overlooking age limits: Effective tenure shortens post-55.
