Formula: Total = (door + hardware + frame + finish + labor) x quantity + 5% misc
Worked example — Total: $1,365 | Per door: $170.63 | Materials: $520 | Labor: $780
Formula
Total = (door + hardware + frame + finish + labor) x quantity + 5% misc
Total cost equals the per-door cost (slab price plus hardware plus optional frame plus finishing cost plus labor hours times hourly rate) multiplied by the number of doors, plus a 5% allowance for miscellaneous supplies like shims, screws, and caulk.
Worked Examples

Frequently Asked Questions
How much does it cost to replace interior doors on average?
The average cost to replace an interior door ranges from $200 to $650 per door installed, with most homeowners spending around $350 per door. This includes the door slab ($50-$500 depending on material and style), hardware ($15-$150), and professional installation ($100-$200 per door at typical labor rates). Hollow-core doors are the most affordable option at $50-$120 for the slab, while solid wood doors can cost $250-$500 or more. If the door frame needs replacement, add another $50-$150 per opening. A typical home renovation replacing 8-10 interior doors costs between $2,000 and $5,000. Costs vary significantly by region, with urban areas generally having higher labor rates than rural areas.
What is the difference between hollow-core and solid-core interior doors?
Hollow-core doors have a cardboard honeycomb interior wrapped in a thin veneer or MDF skin, making them lightweight (15-20 lbs) and affordable ($50-$120). They provide minimal sound insulation and feel less substantial. Solid-core doors have a composite wood fiber core that makes them heavier (40-60 lbs) and provides significantly better sound dampening, fire resistance, and durability. They cost $120-$250 and are recommended for bedrooms, bathrooms, and home offices. Solid wood doors are the premium option ($250-$500+), crafted from hardwoods like oak, maple, or mahogany. They offer the best sound insulation, longest lifespan, and most premium feel, but require more maintenance as they can warp or expand with humidity changes.
Should I replace my interior doors myself or hire a professional?
DIY door replacement can save 40-60% of total cost by eliminating labor charges. If you are replacing a door in an existing frame (slab-only swap), it is a moderate DIY project requiring basic tools like a drill, chisel, level, and shims. The main challenges are properly aligning hinges, ensuring the door swings freely, and getting even gaps around the frame. Professional installation is recommended when you need to replace the frame and jamb, when walls are not plumb or square (common in older homes), for pocket doors or barn doors that require hardware tracks, or when you are doing many doors and want consistent quality. Professional installers typically complete one door in 1-2 hours, while a DIYer might take 2-4 hours per door.
What door styles are most popular for modern home interiors?
Shaker-style doors are currently the most popular choice for interior doors, featuring clean lines with a recessed center panel that complements both modern and transitional design styles. They typically cost $65-$300 depending on material. Flat-panel (flush) doors offer the most minimalist aesthetic, popular in contemporary homes, and are the least expensive at $50-$250. French doors with glass panels are popular for offices, dens, and separating living spaces while maintaining light flow, costing $120-$450 per door. Barn doors have surged in popularity for their rustic-modern aesthetic and space-saving sliding mechanism, ranging from $150-$500 plus hardware track costs of $50-$200. Raised-panel doors remain popular in traditional and colonial-style homes.
How does door hardware selection affect total replacement cost and functionality?
Door hardware significantly impacts both cost and the overall feel of your door upgrade. Basic hardware packages ($15-$25) include a standard lever or knob with a simple latch, adequate for closets and utility rooms. Mid-range hardware ($35-$75) offers better finishes like brushed nickel, oil-rubbed bronze, or matte black, with smoother mechanisms and more design options. Premium hardware ($75-$150) features designer knobs or levers from brands like Schlage or Baldwin with high-quality finishes and superior mechanisms. Smart locks ($150-$300) add keypad or smartphone entry for home offices or private rooms. When replacing multiple doors, choosing matching hardware throughout creates visual consistency. Budget approximately 10-15% of your total door replacement budget for hardware to maintain quality proportional to your door selection.
How much contingency should I budget on top of a renovation cost estimate?
Industry practice is 10-20% contingency on top of the itemized estimate, with older homes (pre-1980, especially pre-1950) warranting the higher end because of the greater chance of hidden problems once walls or floors are opened up — outdated wiring, undersized plumbing, water damage, or non-code framing. Newer homes with recent permit history can budget closer to 10%. Whatever the itemized total on a cost calculator like this one shows, treat it as the floor of your budget, not the ceiling, and don't spend the contingency unless it's actually needed.
