Renovation ROI Methodology
Reviewed by Byron Malone · Last reviewed .
Primary sources
Renovation ROI data is sourced from two annual publications: Remodeling Magazine's Cost vs. Value report (remodeling.hw.net/cost-vs-value/) and the National Association of Realtors Remodeling Impact Report. Remodeling Magazine surveys contractors and Realtors across 150 US markets annually to compute project cost vs. resale value recovered. NAR surveys Realtors on perceived resale impact and homeowner joy scores.
Cost vs. Value methodology: median project cost (from contractor quotes) vs. median value at resale (from Realtor assessments of equivalent homes). ROI = resale value / project cost. These are medians, not means — outlier projects in premium markets can exceed 200% ROI; underperforming markets may yield <50%.
Top ROI projects
Consistent top performers in Cost vs. Value (national median 2024): garage door replacement (194% ROI), steel entry door replacement (188% ROI), manufactured stone veneer (153% ROI), fiber cement siding (89% ROI), minor kitchen remodel (86% ROI). These projects have high ROI because they are visible, high-impact curb appeal items that buyers notice and value.
Consistently low ROI projects: sunroom addition (46%), home office remodel (55%), master suite addition (58%). These have high costs but add less broadly marketable value — they are lifestyle improvements, not resale improvements.
Geographic adjustment
Cost vs. Value provides regional data (Pacific, Mountain, West South Central, East North Central, South Atlantic, New England, etc.). We weight national averages toward the user's selected region. Urban premium markets (SF, NYC, Boston, Seattle) consistently outperform the national average by 15-30% on ROI for the same projects.
Limitations
Cost vs. Value ROI applies at the margin — renovating one kitchen in a neighborhood of unrenovated homes adds more value than renovating 10 kitchens to the same standard. Renovation costs have increased significantly since the 2021-2022 supply chain disruptions; the most recent report is the most applicable. Individual project ROI depends on execution quality — a DIY project may yield different ROI than the contractor-quoted baseline.
