Prices for doorknobs vary widely by material, finish, and installation needs. This guide outlines typical costs and factors that influence the price, helping buyers estimate a realistic budget for a single knob or an entire door set. The main cost drivers are material quality, hardware style, and whether professional installation is required.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Doorknob Unit | $10 | $35 | $250 | Basic to premium materials and styles |
| Installation (labor) | $0 | $60 | $150 | Provided by a handyman or locksmith |
| Total for Single Knob | $10 | $95 | $400 | Assumes standard interior door |
| Tax & Fees | $0 | $6-$15 | $40 | Depends on location |
Overview Of Costs
Cost ranges for a single doorknob typically span from $10 to $250, with total project costs of $10-$400 when including installation and taxes. Basic knobs cost less if DIY installation is possible, while premium hardware and decorative lever sets push toward the higher end. Assumptions include standard interior doors, single-knob sets, and no structural work.

What Drives Price
Material and finish are the primary price drivers. Solid brass and oil-rubbed bronze finishes command higher prices than standard steel or zinc options. The style also matters: modern privacy or passage knobs are usually cheaper than designer or antique-look sets. For some homes, a lockset with integrated privacy or keyed entry adds $20-$100 on the high end.
Ways To Save
DIY installation saves modest amounts when tools and basic hardware skills are available. Compare standard latch-and-rose kits versus premium decorative rosettes, which can add 20% to 80% to the knob price. When replacing multiple doors, buying in bulk or matching finishes can reduce per-knob costs.
Regional Price Differences
Prices shift by region due to labor costs and sales tax. In the Northeast, doorknobs with premium finishes may be more common and priced 5%–15% higher than the national average. The South tends to have slightly lower labor charges, often reducing total installation costs by 5%–10%. Rural areas may show larger price gaps for installation due to travel time or fewer nearby installers, typically +5% to +20% for remote locations.
Labor & Installation Time
Labor for installing a single doorknob generally takes 0.5–1.5 hours depending on door fit and latch compatibility. Higher-end sets or multi-point locking systems can take 2–3 hours. Labor estimates account for tool access, door alignment, and latch compatibility, with hourly rates commonly ranging from $40 to $120 in typical markets.
