Total Cost = (Door Cost + Hardware Cost + Installation) × Number of Doors
Door type costs (per door):
- Hollow core: $30–80 — lightweight, basic, good for closets
- Solid core: $70–250 — sound-dampening, heavier, better quality
- Glass panel: $150–500 — decorative, allows light through
Hardware costs:
- Basic knob set: $10–25
- Lever handle: $20–50
- Privacy lock (bathroom): $15–35
- Hinges (3 per door): $5–15 per set
