How to Use Homejourney Mortgage Calculator: Your Complete 2026 Guide
The Homejourney Mortgage Calculator is your fastest path to understanding how much you can borrow, what your monthly instalments will be, and which bank offers the best rates—all without visiting a single branch or filling out repetitive forms at each bank[1][2]. In just a few minutes, you can calculate your eligibility under Singapore's strict MAS regulations, compare offers from DBS, OCBC, UOB, HSBC, Standard Chartered, Maybank, and more, then submit a single application that reaches all of them simultaneously[1][2].
This guide walks you through every step of using Homejourney's mortgage calculator, explains what the numbers mean, and shows you how to leverage the platform's multi-bank application system to save time and secure the best home loan for your situation.
Why the Homejourney Mortgage Calculator Matters for Singapore Buyers
Singapore's property market operates under strict financial regulations designed to protect buyers from overextending themselves. The Monetary Authority of Singapore (MAS) enforces two critical debt limits: the Total Debt Servicing Ratio (TDSR), which caps your total monthly debt obligations at 55% of your gross monthly income for private property loans, and the Mortgage Servicing Ratio (MSR), which limits your home loan repayments to 30% of income for HDB flats[1][3].
Without a reliable calculator, many buyers rely on outdated spreadsheets, rough mental math, or worst-case scenarios that leave them either underestimating their budget or dangerously overcommitting financially. The Homejourney Mortgage Calculator eliminates this guesswork by automatically applying MAS and HDB rules, integrating real-time interest rates (including the current 3M SORA benchmark), and pulling your actual income and CPF data via Singpass—ensuring your calculations reflect your genuine financial situation, not assumptions[1][2].
For example, a buyer considering a S$600,000 HDB resale flat in Tampines with a 25-year loan tenure at the current 2.6% SORA-based rate would see an estimated monthly instalment of approximately S$2,700[1]. But that same buyer's TDSR limit might cap their maximum loan at S$750,000 if their gross monthly income is S$6,800—meaning the property is affordable, but only if they can cover the downpayment gap with CPF and cash[1]. The calculator shows this instantly, preventing costly mistakes later.
Step 1: Access the Homejourney Mortgage Calculator
Begin your journey at Homejourney's Bank Rates page, where the mortgage calculator lives alongside real-time rate comparisons and eligibility tools[2]. You can access this via the Homejourney website or the Singpass-verified Homejourney app, which centralizes your entire home-buying journey—from property search to loan applications to tracking your offers[1][2].
The Bank Rates page consolidates rates from over 11 major banks including DBS, OCBC, UOB, HSBC, Standard Chartered, Maybank, CIMB, RHB, Public Bank, Hong Leong Bank, and Citibank, updated in real-time to reflect current market conditions[2]. This single page eliminates the need to visit each bank's website separately, saving you hours of research.
Step 2: Choose Your Calculation Goal
The Homejourney Mortgage Calculator supports four primary scenarios, each answering a different question:
- Maximum Loan / Eligibility: "How much can I borrow based on my income, age, and existing debts?" This is where most first-time buyers start, as it defines your budget ceiling[2].
- Monthly Instalment: "If I borrow $X over Y years at Z% interest, what will I pay each month?" Use this to stress-test specific properties or loan amounts.
- Affordability: "Given my income and age, what property price is realistic for me?" This reverses the calculation, starting with your financial capacity and working backward to property price[2].
- Refinancing Scenario: "If I refinance my existing loan, how much will I save?" Current homeowners in areas like Pasir Ris or Bukit Merah can use this to compare their existing rate against new market offers and potentially save S$200+ per month[1].
For first-time buyers, start with maximum loan and monthly instalment calculations to establish your realistic budget before you begin searching for properties on Homejourney's property search platform[2].
Step 3: Log In with Singpass for Instant Data Auto-Fill
This is where Homejourney's calculator saves you the most time. Instead of manually typing your income, CPF balance, employment details, and existing debts, simply log in using your Singpass credentials[1][3]. The system instantly retrieves:
- Your verified gross monthly income (from IRAS tax assessments)
- CPF Ordinary Account (OA) balance and contribution history
- Existing loan obligations (credit cards, personal loans, car financing)
- Employment status and contract type
- Age and retirement date (critical for calculating maximum loan tenure)
This Singpass integration is a game-changer because it eliminates manual entry errors and ensures your calculations are based on your actual financial data, not estimates[1]. For foreigners on Employment Passes, you'll need to upload employment documentation separately, as Singpass doesn't include foreign worker data, but the process remains streamlined[1].
Pro tip: Download your CPF e-statement via Singpass before your first calculator session. This ensures all your CPF data is current and prevents delays if you need to manually verify information later[1].
Step 4: Enter Your Personal Financial Profile
After Singpass auto-fills your data, review and confirm the following information, which forms the foundation of your eligibility calculation:
- Age: Determines your maximum loan tenure (typically up to age 65-70 depending on bank policy)
- Gross Monthly Income: The key denominator for TDSR and MSR calculations
- Existing Debts: All monthly obligations including credit card minimums, personal loans, car loans, and home loans. Note that credit card balances under S$30,000 are typically exempt from TDSR calculations, but confirm this with your bank[1]
- Employment Type: Permanent, contract, self-employed, or retired (affects eligibility and maximum tenure)
- CPF Contribution Status: Whether you're still contributing or have retired (impacts CPF withdrawal eligibility)
The calculator uses these inputs to compute your TDSR headroom—the amount of monthly debt you can still take on while staying within the 55% limit[1]. For example, if your gross monthly income is S$6,000 and your existing debts total S$1,500/month, your TDSR limit allows an additional S$1,800/month in new debt (55% of S$6,000 minus S$1,500 existing), which translates to a maximum home loan of approximately S$550,000 at current rates[1].
Step 5: Input Property Details and Loan Parameters
Now tell the calculator about the property you're buying or considering. This section is crucial because it applies property-specific rules that vary between HDB and private properties:
- Property Type: HDB BTO (Build-to-Order), HDB resale, Executive Condominium (EC), private condo, or landed home. Each category has different LTV (Loan-to-Value) limits and minimum downpayment requirements[2].
- Property Price: Either your target budget (e.g., S$650,000 for a 4-room resale HDB in Sengkang) or the actual asking price of a unit you're eyeing[2].
- Downpayment Amount: The cash and CPF you plan to contribute upfront. For HDB, the minimum is typically 5% cash, with the remainder from CPF OA. For private properties, minimum cash downpayment is usually 5%, with CPF covering up to 80% LTV[2].
- Loan Tenure: The number of years over which you'll repay the loan, typically 15-30 years for HDB and up to 35 years for private residential, subject to your age and MAS rules[2].
The calculator automatically applies current LTV rules. For HDB resale flats, the maximum LTV is 75%, meaning you can borrow up to 75% of the property's value[1]. For private properties, the maximum is 80% LTV[1]. If your downpayment falls short of these minimums, the calculator flags the shortfall so you know exactly how much additional cash or CPF you need to gather.
