How to Use the Renoroi Calculator
Key Takeaways
Kitchen and bathroom renovations consistently deliver the highest rental premium — typically 8–15% uplift in monthly rent for a $50–80K budget.
Renovation ROI is maximised when cost is recovered within one tenancy cycle (2 years) — spending more than $120K on a $1.2M condo makes recovery very slow.
Over-renovating for the neighbourhood destroys ROI: a $150K renovation where comparable units rent for $3,200/month will never fully recover its cost.
Model the sale price uplift alongside rental uplift — buyers pay a visible premium for renovated units, often larger than the rental premium.
Get three renovation quotes before committing — costs for the same specification vary 30–50% across contractors in Singapore.
What It Does
Not all renovations add equal value. Calculate which renovation projects deliver the best ROI by comparing spend against the estimated increase in property value. Prioritise upgrades that maximize resale appeal and avoid overcapitalising in your Singapore condo.
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 renovations do not add proportional value to your property — and some can actually reduce resale appeal. A $100K renovation on a $1M condo rarely translates to a $100K increase in sale price. Understanding renovation ROI helps you:
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 Calculate Renovation Return on Investment" 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. ROI percentage for each renovation category, total value uplift, and ranked priority list.
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.

How to read this:
The priority list: Sarah's kitchen renovation delivers the highest ROI at 80%, followed by bathrooms at 70%. General painting and miscellaneous upgrades have the lowest recoup rate. The calculator helps prioritise where every renovation dollar goes for maximum resale impact. Here are some realistic scenarios you can plug into the calculator right now. Each one reflects a common situation Singapore property buyers face.
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.
Do not over-renovate for the market — A $100K kitchen renovation in a $1M condo rarely adds $100K in resale value. Focus on upgrades buyers actually pay premiums for.
Kitchen and bathrooms deliver the best ROI — Across all markets, these two areas consistently recoup the highest percentage of spend at resale.
Common Pitfalls
Assuming all renovations add value — Some upgrades (highly personal taste, niche fixtures) can actually reduce appeal and resale value. Keep it neutral.
Comparing against wrong benchmarks — ROI should be measured against comparable sales in the same development, not district-wide averages.
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.
What rental premium should I assume for a full renovation?
Research comparable listings in the same development at similar sizes — renovated units typically command 10–20% above unrenovated comparables. This varies by district (CCR commands larger absolute premiums), property type, and how recently the unrenovated baseline was last refreshed. Check ShiokNest's rental listings for the specific development before assuming a premium.

Does renovation affect property tax?
Not directly — IRAS Annual Value is based on market rental comparables, not individual property condition. However, if your renovation pushes your achievable rent above the IRAS benchmark for your development, IRAS may revise your AV upward at the next review cycle, slightly increasing your property tax.
Can I use CPF for renovation costs?
No. CPF OA funds cannot be used for renovation. Only cash or a renovation loan (personal loan from a bank, typically at 3–4% p.a.) can fund renovation costs. Factor in loan interest if you are borrowing for the renovation — the calculator includes an option to model renovation financing costs against the rental ROI.
