Renovation ROI by Project Calculator

This calculator estimates how much of a renovation's cost you'll recoup in home value at resale, starting from national-average cost-recoup percentages modeled on the Cost vs. Value Report — the annual national remodeling-ROI survey published by Zonda Media as the successor to Remodeling Magazine's long-running Cost vs. Value series — for ten common project types. Some projects recoup dramatically more than others: a garage door replacement is set at 194% recoup — meaning it's estimated to add more value than it costs, a well-documented anomaly in renovation ROI data — while a major upscale kitchen remodel sits at just 54%, since expensive kitchens rarely return their full cost at sale. That baseline percentage is then adjusted by three real-world factors. Market condition shifts recoup up to 15% in either direction (buyers pay closer to full value for improvements in a hot seller's market, less in a cold buyer's market).

Neighborhood level applies a ceiling effect: renovating above your neighborhood's typical standard clips the multiplier down, since appraisals and buyers cap what they'll pay based on comparable homes nearby, while an above-median neighborhood gives a modest boost. The calculator also checks for over-improvement risk directly: if your project cost exceeds 15% of your current home's value, a penalty kicks in and scales down as that ratio grows, capping at a 30% reduction — reflecting that spending disproportionately relative to home value hits diminishing returns even before a neighborhood ceiling applies. The final recoup percentage is capped at 200% regardless of inputs. From there, value added, net out-of-pocket cost (project cost minus value added — negative means the project is expected to be a net profit at resale), and new estimated home value are all derived directly. These are historical national averages from published industry surveys, not a valuation of your specific home or market: actual recoup varies by region, exact renovation quality, and how long you hold the home before selling, so use this to compare relative ROI across project types rather than as a precise resale forecast.
