What you get

Made for buyers and sellers who want a clear first answer before talking to an agent, bank or lawyer.

How to use it

Enter the purchase

Add the price, down payment, type of property, who is buying (and any co-buyer) and how many homes you already own.

Check the loan

Add your income, other debts, age, tenure and interest rate to see the repayment at the test rate, your TDSR and MSR, the loan-to-value limit and minimum cash, and the most you could borrow.

See if you sell

Enter a selling price, loan balance, CPF to return and how long you have held the property to see seller’s stamp duty and the cash you keep.

Unlock your full report

Enter your email to get all three calculations on one printable page, with questions to ask your agent, lawyer and bank.

Questions

Do I need to sign up to use it? No — the calculators and their on-screen results are free to use with no account. Your email is only needed if you want the full report.

Are the stamp duty rates current? The rates used are shown on the tool page with the date they were entered. They are indicative, so confirm with IRAS before you rely on them.

Does this approve my loan? No. It checks your numbers against the TDSR, MSR and loan-to-value rules as a rough guide. Banks decide using their own policies and your full details.

Is this financial, tax or legal advice? No — it is a planning aid based on the numbers you enter. See also the free licence and privacy policy.
