Buying property in Singapore involves more than finding the right home or investment. It is important to understand how much you can borrow, the financing rules that apply, and how much cash or CPF you may need upfront.
Whether you are buying your first home, upgrading to a private condominium, or planning your next property investment, these Singapore financing and home loan calculators can help you work through the key numbers before making an offer or committing to a purchase.
Financial & Loan Calculation Tools
1. Singapore Mortgage Calculator
Estimate your monthly mortgage instalments based on your purchase price, down payment, interest rate, and preferred loan tenure. You can test interest rate scenarios to see how the changes impact your monthly commitment and cash flow.

2. Singapore Loan Amortisation Calculator
Generate a comprehensive schedule showing how each monthly repayment is split between principal reduction and interest charges over the life of your mortgage. This helps you track how your loan balance decreases over time and see the exact long-term interest cost under different repayment durations.

3. TDSR Calculator (Total Debt Servicing Ratio)
The TDSR Calculator helps you estimate your maximum home loan based on your income and existing debt commitments.
It takes into account obligations such as credit card balances, car loans and personal loans to determine whether your total monthly debt repayments fall within the applicable 55% TDSR threshold.

4. MSR Calculator (Mortgage Servicing Ratio)
The MSR Calculator is particularly relevant when buying an HDB flat or an Executive Condominium (EC) during its applicable eligibility period.
It helps you estimate the maximum mortgage repayment allowed under the 30% MSR threshold, based on your gross monthly income.

5. Buyer's Stamp Duty (BSD & ABSD) Calculator
Stamp duties can make up a significant part of your upfront property costs. Use the Stamp Duty Calculator to estimate your Buyer’s Stamp Duty (BSD) and Additional Buyer’s Stamp Duty (ABSD) based on your property purchase and buyer profile.
The calculator can be used for Singapore Citizens, Permanent Residents, foreigners and corporate entities, where applicable.

A Structured Approach to Property Financial Planning
Running the numbers before you start viewing properties can help you understand your financial position and avoid taking on more debt than your cash flow can comfortably support.
A simple approach is to work through these calculations in three steps:
Step 1: Understand Your Borrowing Limit
Before securing an Option to Purchase (OTP), use the TDSR Calculator to estimate your borrowing limit. If you are buying an HDB flat or EC, the MSR Calculator can help you further evaluate your mortgage servicing capacity.
This gives you a clearer idea of the loan amount you may be able to obtain under the applicable financing rules.
Step 2: Work Out Your Upfront Costs
Your property budget should account for more than just the downpayment. Buyer’s Stamp Duty (BSD) and, where applicable, Additional Buyer’s Stamp Duty (ABSD) can have a significant impact on the amount of cash and CPF funds required.
Use the Stamp Duty Calculator to estimate these costs before committing to a purchase.
Step 3: Review Your Monthly Cash Flow
Once you have an indication of your potential loan amount, use the Mortgage Calculator to estimate your monthly instalments.
Try different interest rate assumptions to see how your repayments could change. This provides a useful stress test of your monthly cash flow before taking on a long-term mortgage commitment.
Need More Personalised Financial Planning?
Online property calculators provide useful estimates, but your actual borrowing capacity and upfront requirements may vary depending on factors such as variable income, existing financial commitments, CPF usage, age, loan tenure and individual bank assessment criteria.
