You earn $12,000/month and have $200K in cash and $150K in CPF. What is the most expensive property you can buy? The answer is not simply "income × some multiple" — it depends on five different constraints: TDSR, MSR, LTV, cash reserves, and CPF balance. The binding constraint (the one that limits you most) is often not the one you expect.
The Unified Affordability Calculator combines all five constraints into a single maximum price, and tells you exactly which limit is holding you back — so you know where to focus.
What This Calculator 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 This 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:
- It checks all constraints simultaneously: TDSR, MSR, LTV, cash, and CPF
- It identifies which constraint is your binding limit so you know where to focus
- Knowing your true maximum prevents wasted time on properties you cannot finance
What You Will Discover
After running this calculator with your personal numbers, you will know:
- Your maximum affordable property price based on all Singapore financing constraints
- Maximum loan amount under TDSR and MSR limits
- The binding constraint — whether it is income (TDSR/MSR), cash, CPF, or LTV
- A constraint breakdown chart showing how much each factor limits your budget
- Monthly mortgage payment at the maximum affordable price

Worked Example
Meet Rachel, earning $12,000/month gross with a $500/month car loan. She wants to know the maximum property she can afford and which constraint binds first.
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.

| Scenario | Settings to Try | What You Will Learn |
|---|---|---|
| First-timer SC | $10K income, $0 obligations, SC1, private | Your maximum affordable price and which constraint (TDSR, cash, or CPF) is binding |
| HDB upgrader | $12K income, $500 obligations, SC2, private | How existing obligations and IRAS ABSD ratesABSD affect your upgrade budget |
| Dual-income household | $18K combined, $1,000 obligations, SC1, private | The power of combined income on maximum affordable price |
Expert Tips and Common Pitfalls
💡 Pro 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.
- Keep a cash buffer — Do not drain your savings for the down payment. Keep at least 6 months of expenses as an emergency fund after the purchase.
⚠️ 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.
🤔 What-If Scenarios to Explore
Get the most value from this calculator by testing these scenarios:
- What if you have $500/month in car loan obligations? How much does it reduce your budget?
- Compare buying private vs EC — how does the MSR limit change your maximum?
- What if you only have $100K cash but $300K CPF? Which constraint is binding?
- Run at least 3 scenarios — best case, base case, and worst case — to understand the full range of outcomes.
