How to Use the Afford Calculator
Key Takeaways
The calculator checks five constraints simultaneously (TDSR, MSR, LTV, cash, CPF) — missing any one means the deal cannot proceed.
Your binding constraint tells you exactly where to focus: paying off debts, building savings, or contributing more CPF OA.
Banks stress-test your TDSR at 4% regardless of actual rates — use the same rate here to avoid a surprise at the bank.
Run two scenarios: current savings vs savings 12 months from now — the difference shows whether waiting to buy is worth it.
The calculator shows your ceiling, not your comfort zone — borrowing the maximum leaves zero buffer for rate rises or income changes.
What It Does
Discover the maximum property you can afford by combining all Singapore financing constraints in one calculation — TDSR, MSR, LTV, CPF balance, and cash reserves. Identifies which constraint is your binding limit so you know exactly where to focus.
You can find this calculator in the Calculators tab on ShiokNest. It updates results instantly as you adjust inputs — no waiting, no page reloads.
Why It Matters
Most buyers only check one affordability constraint — typically income — but the real limit is often cash on hand, CPF balance, or existing debts. This calculator matters because:
How It Works
Navigate to Calculators — Click the "Calculators" tab in the ShiokNest navigation bar. All 26 calculators are grouped by purpose for easy access.
Select the calculator — Choose "How to Find Your Maximum Affordable Property Price" from the calculator list. You will see default values already loaded so you can explore immediately.
️ Enter your values — Replace the defaults with your own numbers. The key fields are:
Review the results — The calculator updates instantly as you change any input. Maximum affordable price, max loan, monthly payment, binding constraint, and a constraint breakdown chart.
Run what-if scenarios — This is where the real power lies. Change one variable at a time to see its impact. For example, try increasing the interest rate by 1% or extending your holding period by 5 years. Note how the results shift.
Compare and decide — Run 2-3 different scenarios and note the results. This gives you a range of outcomes to base your decision on, rather than relying on a single projection.
Examples
Meet Rachel, earning $12,000/month gross with a $500/month car loan. She wants to know …
Inputs
Monthly Gross Income
$12,000
Existing Monthly Debts
$500 (car loan)
CPF OA Balance
$180,000
Cash Savings
$250,000
Loan Tenure
25 years
Interest Rate
3.5% (stress-tested at 4%)
Results
Max Payment (TDSR)
$6,100/mo
Max Payment (MSR)
$3,100/mo
Max Affordable Price
~$1,541,000
How to read this:
The binding constraint: Rachel's TDSR allows $6,100/month toward mortgage, but her MSR (for HDB/EC) would cap her at $3,100/month. For a private property, TDSR is the binding constraint, giving her a maximum price of approximately $1,541,000. The car loan effect: Without the $500/month car loan, Rachel could afford roughly $750 more in property. The calculator shows exactly how each debt reduces your buying power.
Tips & Pitfalls
Expert Tips
Use realistic assumptions — Singapore condo appreciation has historically averaged 2-4% per year. Avoid overly optimistic projections. When in doubt, use 3% as a baseline.
Stress-test at higher rates — Banks use 4% (or higher) for TDSR stress tests. Run the calculator at 4.5% to see your true worst-case affordability.
Account for lifestyle expenses — The calculator shows the maximum you can borrow, not what you should borrow. Leave room for travel, dining, and savings.
Common Pitfalls
Confusing maximum with comfortable — The calculator shows the ceiling, not the sweet spot. Borrowing the maximum leaves zero buffer for rate increases or income changes.
Forgetting non-mortgage costs — Property tax, condo fees, and renovation are not included in loan affordability but still come out of your pocket every month.
Frequently Asked Questions
Is my data saved?
No. All calculations run entirely in your browser. Nothing is stored on our servers or shared with third parties.
Should I enter gross or net income?
Enter gross monthly income. TDSR and MSR are both assessed on gross income before CPF deductions and income tax — this is the figure your bank will use.
Can I save my results?
Log in to save scenarios to your dashboard, or use the share button to copy a URL that encodes your inputs.
Why does the calculator use 4% instead of the current rate?
MAS requires banks to stress-test TDSR at a floor rate of 4% for private property (3.5% for HDB) regardless of the actual loan rate. This prevents over-borrowing when rates are low. The calculator applies this same floor so your affordability estimate matches what a bank will actually approve.
Does this include ABSD and stamp duty?
No — stamp duty is a separate cash cost that comes out of your savings alongside the downpayment. Use the Stamp Duty Calculator to estimate BSD and ABSD, then deduct this from your available cash before re-running the affordability check.
