US Home improvement ROI calculator

How home improvement ROI is calculated

Renovation ROI compares two numbers: what the project costs, and what it actually adds to the home's resale value (not what it cost — what an appraiser will give you back). The formula:

ROI = (value added − project cost) / project cost

A $30,000 kitchen that adds $24,000 of appraised value at resale has a −20% ROI. The remaining $6,000 is the cost of enjoying the new kitchen yourself.

Typical ROI by project type

• Garage door replacement: ~95% recouped
• Manufactured stone veneer: ~95% recouped
• Entry door replacement: ~85% recouped
• Minor kitchen remodel: ~75–85% recouped
• Bathroom remodel: ~60–70% recouped
• Major kitchen remodel: ~55–65% recouped
• Master suite addition: ~50–55% recouped
• Composite deck addition: ~50–55% recouped
• Pool installation: ~25–40% recouped (often negative in non-pool climates)

These are US national averages — your specific market, the quality of the work, and current housing conditions all matter.

Worked example

You're considering a $25,000 kitchen refresh: countertops, refinished cabinets, mid-tier appliances, fresh paint.

• Expected resale value-add: $20,000 (~80% recoup)
• ROI: ($20,000 − $25,000) / $25,000 = −20%
• Alternative: $25,000 invested at 7% real for 5 years → $35,070
• Net comparison: by selling in 5 years and investing instead, you'd have roughly $10,000 more in net wealth than renovating

If you'd genuinely enjoy the new kitchen for 5 years, that enjoyment is the real return. Frame it as "I'm spending $10,000 net for 5 years of nicer kitchen" — not "this renovation is a financial winner."

When renovations pay off

• You're selling within 12 months and the home shows badly. Cosmetic refreshes (paint, flooring, deep clean, landscaping) often return 200%+ because they shape first impressions.
• A failing system needs replacement anyway. A 25-year-old furnace will fail; replacing proactively avoids a fire-sale repair during a sale.
• The home is at the bottom of its block by amenities. Adding a feature comparable homes have (second bath, garage, modern kitchen) closes the gap.

Common mistakes

• Over-improving for the neighbourhood. An $80,000 kitchen in a $300,000 home rarely returns its cost.
• Personal-taste renovations. Bold colour choices and luxury fixtures often reduce buyer appeal.
• Ignoring opportunity cost. Renovation money is money not invested elsewhere.
• Conflating enjoyment value with financial ROI. They're different — be honest about which one motivates the project.

What this calculator doesn't cover

• Energy-efficiency tax credits (varies by year and country)
• Contractor cost overruns (typically 10–20% above initial estimate)
• Disruption cost while work is underway
