How to use the ROI on Renovation Calculator
Get realistic estimates first
The result is only as good as the inputs. Renovation cost: get written quotes from more than one licensed contractor and add a contingency you can afford, because overruns are common. Before value: what the home would sell for today, as it is. After value: recent sale prices of comparable renovated homes nearby — not what a contractor or agent expects.
Include carrying + selling costs
Carrying costs are the extra monthly costs while the work and the sale take place: interest, tax, insurance, utilities and lost rent for a flip, or costs the work itself causes for an owner. Selling costs are the agent's fee and other costs of sale as a percentage; the 6% default is a placeholder, so enter your market's figure. In owner mode only the fee on the uplift counts against the renovation, because you would pay the fee on the existing value whenever you sold.
Read the uplift multiple
The uplift multiple is the expected rise in sale price per dollar of renovation. Above 1× the work adds more than it costs before carrying and selling costs; below 1× most of the spend is not recovered at sale, which can still be worth it if you value the result while you live there. On the defaults, USD 75,000 of uplift on USD 35,000 of work is 2.14×.
Check a published cost-recovery survey
Surveys estimate the share of a project's cost recouped at resale by project type. In NAR and NARI's 2025 Remodeling Impact Report the top three were a steel front door (100%), a closet renovation (83%) and a fiberglass front door (80%), as estimated by remodelers. Use such figures as a sense check on your after-value, not as a substitute for local sale prices.
Renovation ROI — what the work adds once the costs of selling are counted fairly
A renovation pays for itself only if the sale price rises by more than the work, the extra carrying costs and the extra selling costs together. On this page's defaults — a home worth USD 400,000 before and USD 475,000 after USD 35,000 of work, six months at USD 2,000 of carrying cost and a 6% selling cost — the uplift is USD 75,000. The fee on that uplift is USD 4,500, so the work clears USD 23,500, a 50% return on the USD 47,000 put in.
Why the fee on the whole house is not a renovation cost
This page used to subtract the selling fee on the entire after-renovation price, USD 28,500, from the uplift. An owner pays the fee on the USD 400,000 they already had whether or not they renovate, so charging it to the renovation turned the USD 23,500 gain above into a USD 500 "loss". Only the extra fee, 6% of the USD 75,000 uplift, is caused by the work. In flip mode the whole fee does count, because the sale is the point of the purchase: buying at USD 300,000 and selling at USD 400,000 after the same work and carrying leaves USD 29,000 after a USD 24,000 fee.
The selling fee on the value you already had is a cost of moving, not of renovating. Charge the renovation only with the fee on what it adds.
When renovation is an investment
Three cases stand out. Buying below market because a property needs work, where the discount on purchase is much of the profit. Renovating, renting and then refinancing against the new value, sometimes called BRRRR, which recovers capital without selling if a lender accepts the higher valuation. And repairs a buyer would otherwise price in — a failing roof or plumbing — which may not add value beyond their cost but avoid a larger discount at sale. Outside these, a renovation is usually partly a purchase of something you enjoy while you live there, which is a fine reason, and the uplift multiple shows how much of the spend comes back.
Rules and costs differ by country and building
Selling costs, permits and what counts as a renovation differ widely. Some building types restrict what may be changed and require approved contractors — for a Singapore HDB flat, check HDB's renovation guidelines before you get quotes — and agents' fees vary by market, so replace the 6% default with what a sale would actually cost you.
Why only the fee on the uplift counts, and what 2.14× means on the defaults
On the defaults, USD 75,000 of uplift on USD 35,000 of work is an uplift multiple of 2.14×.
Owner mode charges the fee on the uplift only: 6% × USD 75,000 = USD 4,500, not 6% × USD 475,000 = USD 28,500.
The defaults clear USD 23,500, a 50% return on the USD 47,000 of work and carrying put in.
Every extra month of carrying at USD 2,000 cuts the profit by USD 2,000; the defaults' surplus covers 17.75 months.
Flip mode keeps the whole fee: buy at USD 300,000, sell at USD 400,000 after the same work and carrying, and USD 29,000 is left after a USD 24,000 fee.
An uplift multiple below 1× means the work adds less to the sale price than it costs.
BRRRR — buy, rehab, rent, refinance, repeat — recovers capital by refinancing against the new value instead of selling, if a lender accepts that valuation.
A 0% selling cost now counts as zero; the page used to replace it with the 6% default.
In NAR and NARI's 2025 Remodeling Impact Report, a new steel front door had the highest estimated cost recovery, 100%, ahead of a closet renovation (83%).
Break-even holding = (uplift − fee on the uplift − renovation) ÷ monthly carrying cost.
Frequently Asked Questions
-
It depends on why you are renovating. A flip is a business, so the return has to pay for the capital, the time and the risk that the sale price or the schedule slips; compare it with what that money could earn elsewhere. For an owner who will live in the home, the uplift multiple is the more useful figure: it shows how much of the spend comes back at sale, and the rest is the price of enjoying the result.
-
In the 2025 Remodeling Impact Report from the National Association of Realtors and the National Association of the Remodeling Industry, the projects with the highest cost recovery, as estimated by NARI members, were a new steel front door (100%), a closet renovation (83%) and a new fiberglass front door (80%). Those are US estimates of resale value; use local sale prices for your own after-value, and check the latest edition, because the ranking changes.
-
The same report contrasts cost recovery with satisfaction: the projects homeowners rated highest for joy on completion were a primary bedroom suite, a kitchen upgrade and new roofing, not the projects with the highest cost recovery. Large, personal projects cost a lot and the next buyer may not value them as you do, so treat them as partly a purchase of something you enjoy, and test the after-value against local sales.
-
Yes, in two modes. Flip: enter the purchase price; profit is the sale price less the selling fee on the whole sale, the purchase, the renovation and carrying. Owner: leave the purchase price at 0; profit is the uplift less the selling fee on the uplift, the renovation and any carrying the work causes. The fee on the value you already had is not counted, because you would pay it whenever you sold.
-
They're selling, not auditing. Contractors have a financial interest in projects happening — and they're not the ones liable if the resale uplift doesn't materialise. Real estate agents have similar conflicts (their commission is based on sale price, but they only get paid IF the sale happens). The single most reliable source: comparable sales data — what did similar homes WITH and WITHOUT the renovation actually sell for? Get this from your local MLS, Zillow, Redfin, Realtor.com, PropertyGuru, 99.co, Lamudi. Don't trust prospective numbers from anyone with a financial stake in your project.
-
Different math entirely. With long horizons, renovation becomes BOTH lifestyle AND investment (because real estate appreciates over time, and well-maintained homes appreciate more than neglected ones). Run the math two ways: (1) Standard recoupment analysis (this calculator) for the renovation itself. (2) Maintenance avoidance: how much will the cost of deferred maintenance compound if you DON'T fix the roof / electrical / plumbing now? Long-tenure owners often justify renovations as "fixing things before they break", which has different ROI than "upgrading for resale." Both can be legitimate; just label them honestly.
-
Notoriously unreliable unless you anchor to real comparable sales. Methods, ranked by accuracy: Best: comparable post-renovation sales in your immediate neighbourhood within last 6 months (same school district, same building / development). Good: licensed appraiser's pre-renovation estimate with comp adjustments. Mediocre: real estate agent's CMA (comparative market analysis) — biased toward listing-incentive. Poor: contractor's verbal promise. Worthless: HGTV / generic blog "average uplift" numbers. For ASEAN markets, use PropertyGuru / 99.co historical sold-prices, not asking prices.
-
Buy, Rehab, Rent, Refinance, Repeat. You buy a property that needs work, renovate it, let it, then refinance against the new appraised value to take out much of the money you put in, while keeping the property and its rent. It avoids the costs of selling, but it depends on a lender accepting the higher valuation, on rent covering the larger loan, and on the renovation budget holding.

For work that needs no licence — painting, simple landscaping, replacing fixtures — doing it yourself removes the labour from the cost, which raises the uplift multiple if the finish is good enough not to lower the sale price. For electrical, plumbing, gas and structural work, use licensed contractors: rules differ by country and building type, and work that fails an inspection at sale costs more to fix than to do properly. In Singapore, check HDB's or the building's renovation rules before starting.
Method & sources
How it computes
Flip: profit = sale - selling% x sale - purchase - renovation - carrying. Owner: profit = (after - before) - selling% x UPLIFT - renovation - carrying. ROI = profit / cash put in; uplift multiple = uplift / renovation cost; break-even holding = surplus before carrying / monthly carrying. RecaProperty.renovation, tested.
What this tool implements
- Bug fixed: owner mode charged the selling fee on the ENTIRE after-renovation price to the renovation. The owner pays the fee on the before-value whether or not they renovate, so only the fee on the uplift belongs to the work. On the page's defaults (400,000 to 475,000, 35,000 work, 12,000 carrying, 6%) it reported a USD 500 loss for a renovation that clears USD 23,500 (50% on 47,000). Also fixed: a typed 0% selling cost silently became 6%; a break-even over 240 months read 'Already profitable'.
- Cost-recovery figures now from NAR and NARI's 2025 Remodeling Impact Report (steel front door 100%, closet renovation 83%, fiberglass front door 80%, as estimated by NARI members). The page's undated 'Cost vs Value' percentages could not be checked (the publisher's site is behind a CAPTCHA) and were removed.
- Removed as unsourced: 15-30% overrun rates, USD 1,500-3,000 monthly carrying, agent commission percentages by country, the flipper '30% below ARV' and '20% ROI' targets, BRRRR as 'the most reliable' strategy, ASEAN renovation cost ranges, and 'DIY saves 30-50%'.
