The affordability calculator tells you the maximum property price you can realistically buy in Singapore based on your income, existing debts, cash and CPF savings, and the loan a bank will approve under MAS rules. Instead of guessing, you get a clear price ceiling before you start viewing homes.
Buying a property in Singapore is not simply about the price tag. Your real budget is the sum of the home loan a bank will grant you plus the cash and CPF you can put down. This calculator pulls those pieces together in one place. You enter your gross monthly income, any existing monthly debt repayments, your available savings, and the type of property you are eyeing. It then estimates the largest purchase price you can support without breaching Singapore's lending rules.
In short, it answers the single most important question at the start of any property search: how much can I actually afford?
Three regulatory limits set by the Monetary Authority of Singapore (MAS) shape your maximum loan.
The Total Debt Servicing Ratio (TDSR) caps your total monthly debt repayments at 55% of your gross monthly income. This includes the new home loan plus car loans, personal loans, credit card minimums and any other commitments.
The Mortgage Servicing Ratio (MSR) applies only to HDB flats and Executive Condominiums. It limits your monthly housing loan repayment to 30% of gross monthly income, and it is checked alongside TDSR.
The Loan-to-Value (LTV) limit caps how much you can borrow against the property value. For a first private housing loan the LTV is up to 75%, meaning you fund at least 25% of the price through downpayment (with at least 5% in cash). HDB loans are capped at 75% as well following the August 2024 revision.
Banks also apply a stress-test interest rate of 4% per annum (or the prevailing rate if higher) when sizing your loan, so your approved amount reflects affordability even if rates climb.
This calculator is built for anyone at the planning stage: first-time buyers working out whether a condo or HDB resale flat is within reach, upgraders checking what they can stretch to after selling, and investors confirming a budget before committing. Property agents and mortgage advisers also use it to set client expectations early.
Suppose a couple earns a combined S$12,000 gross per month with a S$600 car loan. Under the 55% TDSR cap, they can service up to S$6,600 in total monthly debt, leaving S$6,000 for a mortgage. At a 4% stress rate over a 30-year tenure, that supports a loan of roughly S$1.25 million. Add a 25% downpayment funded by cash and CPF, and their realistic budget lands near S$1.6 million, before stamp duty and fees. The calculator runs this maths instantly and adjusts as you change any input.
Starting your search with a verified number saves time and disappointment. It prevents you from falling for homes outside your range, gives you negotiating confidence, and lets you plan for upfront costs such as Buyer's Stamp Duty and legal fees. It also flags early whether you need to reduce existing debt or save more before applying for a loan.
As a rough guide, your maximum loan is whatever keeps total monthly debt within 55% of gross income at a 4% stress rate, then add your downpayment. The calculator gives a precise figure tailored to your numbers.
The core output is your maximum purchase price and loan. You should budget separately for Buyer's Stamp Duty, legal fees and renovation, which our stamp duty calculator can estimate.
Yes. Every monthly commitment counts toward your 55% TDSR limit, so existing loans directly reduce how much you can borrow for a home.
No. It is a reliable estimate based on MAS rules. Actual approval depends on the bank's assessment of your credit profile, income documents and the specific property.
A longer tenure lowers monthly repayments and can raise your maximum loan, but tenure is capped (typically 30 years for private property, 25 for HDB) and longer loans cost more in total interest.

The sell-one-buy-two calculator models the Singapore strategy where a couple sells their jointly owned home and each spouse buys a separate property in their sole name, allowing both purchases to qualify as first homes and avoid second-property ABSD. It calculates net sale proceeds, available cash and CPF, individual loan eligibility under TDSR, stamp duty on each new purchase, and total upfront cash required to confirm whether the strategy is feasible.

The decoupling calculator helps Singapore property co-owners determine whether transferring one owner's share to the other is financially worthwhile. It compares the Additional Buyer's Stamp Duty saved on a subsequent purchase against the costs of decoupling, including Buyer's Stamp Duty on the transferred share, legal fees, and refinancing costs, to produce a net benefit figure.
