Buyers typically pay for the door itself, the frame or prehung unit, hardware, and labor. Main cost drivers include door material, whether it’s hollow or solid core, size, and whether installation is included.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Door (hollow core) | $40 | $120 | $250 | Most economical interior option |
| Door (solid core) | $150 | $350 | $600 | Better sound/durability |
| Prehung unit (door + frame) | $150 | $350 | $700 | Includes basic jamb |
| Hardware (knob/lever, latch) | $20 | $60 | $150 | Includes strike plate |
| Labor (installation) | $100 | $300 | $800 | Depends on crew and access |
| Finishing/paint/stain | $20 | $60 | $200 | Depends on finish |
Overview Of Costs
Cost ranges reflect typical residential interior doors, with or without installation. The total installed price usually spans from about $200 to $900 for most standard doors, while premium doors or custom sizes can push higher. The per-unit price for a basic hollow core door is commonly in the $40–$120 range, with installation adding $100–$300 on average.
Cost Breakdown
Table shows how components contribute to the total door project. A standard interior room door typically involves a door slab, a frame or prehung unit, hardware, and labor. The exact mix depends on door type, size, and whether any finishing work is required.
| Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials | $40 | $120 | $600 | Hollow vs solid core, wood species |
| Labor | $100 | $300 | $800 | Removal, fitting, alignment |
| Hardware | $20 | $60 | $150 | Knob/lever, hinges |
| Frame/Prehung | $150 | $350 | $700 | Includes jamb and shims |
| Finishing | $0 | $60 | $200 | Paint or stain |
| Permits/Delivery | $0 | $20 | $100 | Depending on locality |
What Drives Price
Material quality, door type, and installation complexity are primary drivers. Hollow core doors are inexpensive but less quiet; solid core doors cost more but offer better sound control. Prehung doors simplify installation but add to upfront cost. Size, irregular openings, and high-end finishes (stain, veneer, or fiberglass) push prices higher.
Labor, Hours & Rates
Labor is often the largest variable beyond material. Typical interior door installations run 1–4 hours, depending on whether hinges, hardware, and trimming require extra work. In urban areas, labor rates commonly range from $60 to $120 per hour; rural areas may be slightly lower. For a standard single door, expect around $120–$350 in labor if everything is ready to install.
Regional Price Differences
Prices vary by region due to material costs and labor markets. In the Northeast, total installed costs may run 10–15% higher than the national average. The South tends to be 5–10% lower, while the Midwest sits near the national average with occasional regional discounts. Expect +/- 8–12% variation when comparing urban, suburban, and rural settings for similar door configurations.
Additional & Hidden Costs
Hidden fees can affect the final bill. Hidden items include disposal of old doors, extra trim or casing, HVAC adjustments for door closers, and disposal of packaging. If the opening requires reframing or adjusting studs for a nonstandard size, costs can add $150–$500. Some projects need permits or inspections in certain jurisdictions, adding $50–$150.

Pricing FAQ
Frequently asked questions help clarify common cost questions. Do interior doors require permits? Most residential interior door installs do not require permits unless part of a larger remodel. Can I install a door myself to save money? Yes, but alignments and air sealing matter for fit and function; errors can add costs later. Are there energy-efficiency options? Yes, solid core or fiberglass doors offer better insulation and can affect long-term energy costs.
