How to Visualize Lease Decay in Singapore

How-To Updated

A 99-year leasehold property does not lose value in a straight line — it follows a curve that starts gentle and then accelerates dramatically. A property with 60 years remaining retains about 79% of freehold value. At 30 years, it drops to 46%. And below 20 years, CPF cannot even be used for purchase, making the property extremely hard to sell.

The lease decay Visualizer plots this curve using Singapore's official Bala's Table, showing exactly where your property sits on the depreciation curve and when the critical thresholds hit.

What This Calculator Does

Understand how leasehold property values diminish over time using Singapore's Bala's Table. Compare 99-year, 999-year, and freehold properties side by side. See the critical CPF eligibility threshold and learn when lease decay accelerates — essential knowledge for any leasehold buyer.

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

Lease decay is the number one risk in 99-year leasehold property that many Singapore buyers ignore or underestimate. The decay is not linear — it accelerates dramatically in the final decades. This calculator matters because:

  • A property with 60 years remaining may retain only 70-75% of its freehold-equivalent value
  • CPF usage restrictions kick in as remaining lease shortens, shrinking your buyer pool at exit
  • Understanding the decay curve helps you decide whether the freehold premium is justified

What You Will Discover

After running this calculator with your personal numbers, you will know:

  • A visual decay curve for 99-year, 999-year, and freehold properties
  • Where your property sits on the decay curve based on its current remaining lease
  • The critical CPF eligibility threshold and when your property crosses it
  • How much value your leasehold property has already lost compared to freehold equivalent
  • Whether lease decay will outpace appreciation over your planned holding period

  3. ✏️ Enter your values — Replace the defaults with your own numbers. The key fields are:
    • Purchase Price — The total property price before additional costs.
  4. 📊 Review the results — The calculator updates instantly as you change any input. A decay curve for 99-year, 999-year, and freehold leases, with your property marked on the chart.
  5. 🔄 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.
  6. 💾 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.

Worked Example

Meet David, evaluating a 99-year leasehold condo that is 20 years old (remaining lease: 79 years). He wants to understand how much value has already decayed and what happens over the next 20 years.

79 years
Remaining Lease
74.6%
Est. Value Retention
Yes
CPF Eligible

The decay reality: At 79 years remaining, the property retains approximately 74.6% of its freehold-equivalent value. CPF can still be used because the remaining lease exceeds the minimum threshold. However, if David holds for 20 more years, the remaining lease drops to 59 years — entering the accelerated decay zone where value drops significantly faster.

The key question: Will capital appreciation outpace lease decay? The visualizer shows both curves so David can see exactly when decay overtakes growth — the point at which holding becomes value-destructive.

Real-World Scenarios to Try

Here are some realistic scenarios you can plug into the calculator right now. Each one reflects a common situation Singapore property buyers face.

ScenarioSettings to TryWhat You Will Learn
Young lease$1.5M, 90 years remainingHow minimal the decay is when the lease is still long — and when it starts accelerating
Mid-life lease$1.2M, 60 years remainingThe tipping point where banks start reducing LTV and value drops sharply
Ageing lease$800K, 40 years remainingHow quickly value erodes and whether the price discount justifies the risk

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.
  • Watch the 60-year cliff — Lease decay accelerates dramatically once remaining lease drops below 60 years. The value loss per year roughly doubles compared to the first 40 years.
  • Know the CPF 20-year cutoff — If the remaining lease at your age + 95 is below 20 years, CPF usage is restricted or blocked entirely. This reduces your buyer pool.
  • Justify the freehold premium — Use this visualizer to see if the premium for freehold (typically 10-20%) is justified by the value preservation over your holding period.

⚠️ Common Pitfalls

  • Ignoring the remaining lease at point of sale — Many buyers focus on today's remaining lease but forget it will be 10-15 years shorter when they sell. Model the exit, not just the entry.
  • Assuming "999-year is the same as freehold" — While practically similar, some banks and CPF rules treat them differently. Do not assume they are interchangeable.

🤔 What-If Scenarios to Explore

Get the most value from this calculator by testing these scenarios:

  • Compare a 30-year-old vs 60-year-old 99-year lease — where does decay accelerate?
  • How does a 999-year lease compare to freehold in terms of CPF eligibility and bank financing?
  • At what remaining lease do banks start restricting loan tenure?
  • Run at least 3 scenarios — best case, base case, and worst case — to understand the full range of outcomes.
