Home Renovation ROI Calculator

Estimate how much resale value a home renovation project adds and what percentage of the project cost you can expect to recoup, based on national average cost-vs-value data by project type.

Home Renovation ROI Formula

This calculator applies an average 'cost recouped' percentage for a given project type to your actual project cost, estimating the added resale value and whether the renovation is likely to pay for itself at sale.

Estimated Value Added = Project Cost × (Recoup % ÷ 100)
Net Gain or Loss = Estimated Value Added − Project Cost
New Home Value = Current Home Value + Estimated Value Added
Cost Not Recouped = max(0, Project Cost − Estimated Value Added)

Recoup percentages are national averages drawn from cost-vs-value industry research and vary by project type, home price range, region, and quality of work. Projects like garage door and entry door replacements often recoup more than 100% of their cost, while large upscale remodels (major kitchen renovations, basements) typically recoup less than the amount spent. These figures are directional estimates, not guarantees of resale value.

How to Use the Home Renovation ROI Calculator

1

Select a project type

Choose from common renovation projects such as kitchen remodels, bathroom remodels, deck additions, siding replacement, or garage door replacement, each with its own average recoup percentage.

2

Enter your project cost

Input your actual or estimated budget for the renovation project.

3

Enter your current home value

Add your home's current estimated market value to see the projected value after the renovation.

4

Use a custom recoup percentage (optional)

If your project doesn't match a standard category, select 'Custom Project' and enter your own estimated recoup percentage.

5

Click Calculate

View the estimated value added, net gain or loss, new home value, and any cost not recouped at resale.

Real-World Scenario Example

"A homeowner with a $450,000 home spends $28,000 on a minor kitchen remodel, which historically recoups about 113% of its cost at resale."

Inputs

projectType:minorKitchen
projectCost:28000
customRecoupPercent:0
currentHomeValue:450000

Result

The remodel is estimated to add about $31,640 in resale value — a net gain of roughly $3,640 — bringing the estimated home value to about $481,640.

Important Disclaimer

Recoup percentages are national averages for educational and planning purposes only and do not guarantee any specific resale value. Actual returns depend on local market conditions, home price range, renovation quality, and timing of sale. Consult a local real estate professional or appraiser for property-specific estimates.
