Do new windows add value? Window replacement ROI calculator
New windows sell on comfort and energy bills more than on resale: they recover about three-quarters of their cost, then keep paying in lower heating and cooling costs. Here is the resale half of that math.
Directional estimate using national cost-vs-value recoup rates (2025 Cost vs. Value report). Returns vary widely by market, quality, and timing — not an appraisal.
How much value do new windows add?
Replacing 10 windows with insulated vinyl units (about $22,000) recouped roughly 76% of its cost in the 2025 Cost vs. Value report; wood windows (about $27,000) recouped about 70%. Add typical energy savings of a few hundred dollars a year and the lifetime return improves, but on resale alone windows sit in the middle of the pack.
Where windows do move value is when the existing ones are failing — fogged double panes, rot, painted-shut sashes, single-pane glass — because buyers and inspectors treat those as a must-fix.
What drives window ROI
Condition of the old windows. Replacing failed or single-pane windows returns the most; replacing working 15-year-old double-panes returns little.
Energy ratings. Low-E, argon-filled units with a good U-factor are what buyers in cold and hot climates look for.
Full set vs. partial. Mismatched windows look like a patch job; replace by elevation at least.
Material fit. Vinyl suits most homes; wood or clad-wood pays back on historic or high-end houses where vinyl would look wrong.
Vinyl vs. wood
Vinyl: lower cost, higher recoup, no painting, 20–30-year life — the default choice.
Wood or clad-wood: about 25% more, slightly lower recoup, better looks and longer life on the right house.
