Window Replacement Cost Calculator
TL;DR: In 2026, replacing windows in the U.S. typically costs $480–$2,200 per window installed, with the national median near $720 per vinyl double-hung insert and $1,250 per fiberglass full-frame.
Bottom line
- Typical range: $480 – $2,200 per window installed
- Median: $720 (vinyl insert) · $1,250 (fiberglass full-frame) · $13,800 whole-house (16 windows)
- Biggest driver: Frame material + install type (full-frame costs ~1.7× pocket insert)
- When this applies: Replace at 20–25 yrs for vinyl, 30–40 yrs for fiberglass/wood, or sooner with seal failure (fogging) or rot.
2026 installed window replacement cost by material and install type
| Frame material | Insert/pocket | Full-frame | Per whole house (16 windows) | Lifespan |

Overview
Window pricing is driven by five variables: frame material (vinyl, fiberglass, wood, aluminum-clad), glass package (Low-E, triple-pane, argon/krypton fill), install type (insert/pocket vs full-frame), window count, and any structural changes (rot repair, header sizing). This calculator uses 2026 manufacturer MSRPs from Andersen, Pella, Marvin, Milgard, and major regional brands plus current installer labor rates. Use this page if you're seeing fogged glass between panes, drafts, or rising heating bills, or you're planning a whole-house upgrade. Output includes a per-window estimate, a whole-house total, an energy-savings forecast, and a 'best brand for your climate' recommendation.
FAQs
How much do new windows cost in 2026?
Replacement windows cost $480–$2,200 per window installed in 2026. The national median is $720 for a vinyl double-hung insert and $1,250 for a fiberglass full-frame replacement. A typical 16-window whole-house upgrade with mid-tier vinyl runs $13,800 nationally; the same project in fiberglass runs $18,400.
Insert vs full-frame replacement — which should I choose?
Choose insert (pocket) replacement when the existing frame is sound, you want to save 30–40%, and you don't need to fix water damage. Choose full-frame when there is rot, the original windows are 40+ years old, you're changing the window size, or you want to maximize glass area. Full-frame adds $200–$500 per window but lasts the full lifespan of the new product.
Are triple-pane windows worth it?
In zones 5–7 (cold winters, heating-dominated), triple-pane delivers an extra 15–25% energy savings vs double-pane Low-E and pays back in 8–14 years. In zones 1–4 (warm, cooling-dominated), the marginal benefit is too small to justify the +$2,400 whole-house premium. Stick with double-pane Low-E + argon for most of the South and Southwest.
Which window brand is best in 2026?
Best by category: Andersen 100 Series (best vinyl value), Marvin Elevate (best fiberglass), Pella Lifestyle (best wood-clad), Milgard Tuscany (best West Coast vinyl), Window World (best budget national). Match the brand to your climate zone and salt-air exposure rather than picking by reputation alone.
How long does whole-house window replacement take?
A 16-window insert replacement takes 2–3 days for a 3-person crew. Full-frame replacement of the same project takes 3–5 days because of trim work and exterior wrap. Custom-order windows typically take 4–8 weeks to arrive after measurement.
Will new windows really cut my energy bill?
Replacing single-pane windows with Low-E double-pane typically reduces heating and cooling costs by 12–18% in cold climates and 8–14% in hot climates. Replacing already-functional double-pane windows usually saves only 4–8% — the payback math doesn't justify replacement on energy alone in that scenario.
