The fastest way to use the Homejourney Mortgage Calculator is to go to the bank rates page, enter your income, debts, and property details, then let the tool compute your loan eligibility, monthly instalments, and affordability before you submit a multi-bank application so banks compete for you.
This cluster guide sits under Homejourney’s main Singapore Home Loans Pillar Guide, and focuses specifically on how to use Homejourney Mortgage Calculator step by step so you can compare bank offers, apply multiple banks mortgage, and get best mortgage rate safely and confidently.
What Homejourney Mortgage Calculator Does in One Sentence
The Homejourney Mortgage Calculator estimates your maximum loan amount, monthly instalment, and total interest cost based on your income, age, debts, property price and current bank rates, then connects you to a multi-bank application so you can receive offers from DBS, OCBC, UOB, HSBC, Standard Chartered, Maybank, CIMB, RHB and more with one secure Singpass submission.Bank Rates
For Singapore buyers and investors, this means you no longer need to visit every bank separately or worry if your calculations follow MAS rules like Total Debt Servicing Ratio (TDSR) and Mortgage Servicing Ratio (MSR).[1][2][3]
Why Use Homejourney Mortgage Calculator Before Any Home Search
In Singapore, property prices and loan rules are strict, and miscalculating by even S$50,000 can mean losing your OTP or over-stretching your monthly budget.
Homejourney’s calculator is designed to protect you by:
- Applying the latest MAS TDSR cap of 55% of gross monthly income for private property loans automatically.[1][2][3]
- Checking MSR (usually 30% of income) for HDB and EC buyers where applicable, so you do not over-commit on flats in areas like Punggol, Tampines or Woodlands.[1][2]
- Using live bank rates from DBS, OCBC, UOB, HSBC, Standard Chartered, Maybank, CIMB, RHB, Public Bank, Hong Leong Bank and Citibank instead of outdated assumptions.[2][3]
- Integrating Singpass/MyInfo so your income, CPF OA, and existing loans are verified for more accurate eligibility results.[1][2][4][6]
For example, if you are eyeing a S$600,000 4-room HDB resale in Bedok near Bedok MRT (about a 5-minute walk from the station), Homejourney Mortgage Calculator can show you in under 5 minutes whether your income (say, S$7,000 combined) can safely support the loan, how much CPF OA you need, and what your monthly instalment looks like after CPF deductions.[1][2][3]
Step-by-Step: How to Use Homejourney Mortgage Calculator
Step 1 – Go to the Bank Rates & Calculator Page
Start at the Homejourney Bank Rates page where the mortgage calculator, eligibility calculator, and multi-bank application are combined for a seamless journey.[2][3]Bank Rates
You can access it via desktop or the Homejourney app (Singpass-verified tools are available on both for secure use).[2][4][6]
Insider tip: Many Singaporeans check the calculator on their phones while visiting showflats in areas like Lentor or Tengah on weekends. Use the calculator just before you sign any Expression of Interest so you do not get carried away by marketing brochures.
Step 2 – Choose What You Want to Calculate
The Homejourney Mortgage Calculator typically gives you a few clear options:[2][3]
- How much can I borrow? (Maximum loan / eligibility)
- Monthly instalment (If you already know the loan amount)
- Affordability (What property price fits your income and age)
- Refinancing (How your monthly payment changes if you switch bank or package)
For first-time HDB buyers, start with affordability, then match your budget to units on Homejourney’s Property Search and Projects Directory so you only view homes you can truly afford.[2][3]Property Search Projects Directory
Step 3 – Log In with Singpass (Recommended for Accuracy)
When prompted, log in using Singpass/MyInfo. This lets Homejourney pull your IRAS income data, CPF OA balances, and existing loans securely, so your TDSR and MSR calculations are based on verified information.[1][2][4][6]
You can still input details manually, but Singpass saves time and reduces mistakes such as forgetting a small personal loan or under-reporting credit card instalments.
Insider tip: Before visiting popular resale hotspots like Queenstown or Toa Payoh (where viewing slots can be tight), log in to Homejourney with Singpass the night before and save your profile. The next day, you only adjust the property price and tenure – your income and debt data are already filled in.
Step 4 – Enter Your Basic Profile for TDSR & MSR
Whether you use Singpass or manual entry, check that these fields are accurate:[1][2][3]
- Age (affects maximum loan tenure – usually up to 30 years for HDB, 35 years for private)
- Gross monthly income (basic + fixed allowances)
- Existing monthly debts (car loans, student loans, personal loans, credit card instalments)
- Number of borrowers (single buyer vs joint application with spouse or family)
The calculator applies MAS’s TDSR 55% cap to ensure your total monthly debt (including the new mortgage) does not exceed this percentage of your combined gross income.[1][2][3]
For HDB and EC buyers, the calculator also checks MSR, which typically caps your monthly mortgage at 30% of income.[1][3]
Step 5 – Add Property Details (Type, Price, Downpayment, Tenure)
Next, fill in the property-specific fields so the calculator can estimate your loan-to-value (LTV), cash requirements, and monthly instalment accurately.[1][2][3]
- Property type: HDB BTO, HDB resale, EC, private condo, landed.
- Property price: For example, S$520,000 for a 4-room HDB resale in Tampines, or S$1.5M for a 3-bed condo in Upper Thomson.
- Downpayment: How much cash + CPF OA you plan to use.
- Loan tenure: Commonly 25–30 years for HDB, up to 35 years for private, subject to MAS/HDB rules.
The calculator then applies prevailing LTV limits (e.g. up to 75%–80% for first housing loan, lower if you already have existing property loans) and minimum cash downpayment rules from MAS and HDB frameworks.[1][2][3]
Real-life scenario: For a S$650,000 4-room resale flat in Sengkang near Compass One (around 5–7 minutes’ walk from Sengkang MRT), the calculator can instantly show whether your CPF OA savings plus cash can cover the downpayment and stamp duties, and what your monthly repayment will look like if you choose a 25-year vs 30-year tenure.
Step 6 – Choose Interest Rate Type: SORA Floating vs Fixed
Homejourney lets you select between SORA-based floating packages (3M or 6M SORA) and fixed-rate scenarios using real-time data tracked against MAS-published benchmarks.[2][3]
In 2025–2026, most major banks in Singapore structure their home loans around 3M or 6M SORA plus a spread. A floating package might look like “3M SORA + 0.7%”, which means your rate will move when MAS updates SORA.[3]
Homejourney’s calculator pulls these live rates so you do not have to guess.
The chart below shows recent interest rate trends in Singapore:
By looking at the trend, you can quickly see whether SORA rates are trending up or down, which helps you decide between fixed vs floating and how much buffer to build into your budget.
Pro tip: Use Homejourney’s real-time SORA tracking to test slightly higher rates (for example, add 0.5% to today’s rate) in the calculator. If you can still comfortably afford the monthly instalment, you are better protected if rates rise in future.[2][3]
Step 7 – Review Your Results: Eligibility, Instalment & Safety Checks
After you click Calculate, Homejourney Mortgage Calculator immediately shows:[1][2][3]
- Your estimated maximum loan amount
- Monthly instalment and breakdown (principal vs interest)
- Total interest over the full tenure
- How much cash and CPF OA you need upfront
- Whether you pass TDSR and (if relevant) MSR
If your preferred scenario breaches TDSR or MSR, the tool will indicate that your debt ratio is too high. In that case, try:
- Reducing the property price
- Increasing your downpayment (more CPF OA or cash)
- Extending your loan tenure within allowable limits
Safety-first tip: Even if the calculator shows you are within TDSR 55%, consider staying below 45–50% in real life to leave room for life events like having children, job changes or caring for parents. This is not a regulation, but a conservative practice many experienced buyers in Singapore follow.
From Calculation to Application: Let Banks Compete for You
Once you are satisfied with your budget and monthly repayment, the next step is to turn your calculation into a real application – without visiting multiple bank branches or filling up separate forms.

Documentation Checklist for a Smooth Application
To get the most accurate results from Homejourney Mortgage Calculator and speed up your multi-bank application, prepare these documents (even if you are applying via Singpass):[1][2][3][5]
- NRIC (front and back) for Singapore Citizens/PRs, or passport and work pass for foreigners.
- Latest 3 months’ payslips or latest Notice of Assessment from IRAS (downloadable via myTax Portal with Singpass).
- CPF OA statement (available via cpf.gov.sg with Singpass), especially important for HDB buyers using OA funds for downpayment.
- Existing loan statements (car, personal, renovation, education) and any ongoing hire purchases.
- HDB option documents or OTP for private property when you have secured a unit.
Preparation tip: If you live in the heartlands like Jurong West or Hougang and plan to view several resale flats in one afternoon, save these documents in a secure cloud folder. That way, when you find a serious unit, you can complete your Homejourney multi-bank application that same evening and lock in a rate before market moves.
Common Pitfalls to Avoid When Using Mortgage Calculators
Even with a powerful tool, some common mistakes can still derail your plans. Here are key issues to watch out for:
- Under-declaring debts: Leaving out small instalment plans or buy-now-pay-later schemes can cause your actual bank-approved loan to be lower than what the calculator shows.
- Over-optimistic income: Using potential bonuses as stable income can mislead your affordability results. Stick to confirmed basic and regular allowances.
