This calculator vs. a flat price per door
“$339 a door” is not a price for a cabinet refinish — it is a price for one specific door count, drawer ratio, finish method, and color change, quietly applied to every kitchen that calls in.
What a flat price per door is
A flat price per door is the fastest way to quote: multiply the door count by a number and read off a price. Homeowners shop it because it is easy to compare between bids, and it is the number a homeowner holding a competitor's flyer will ask you to match.
The number behind it was set for one kitchen — a shop-sprayed galley, one finish color, existing hardware reinstalled — and then reused for every kitchen afterward, whether or not the next job carries the same drawer fronts, hardware, finish method, and color change.
What this calculator is
This page keeps no account and sends nothing to a server. You enter the doors, drawer fronts, face-frame openings, and hardware pieces, the finish method (shop spray, on-site spray, or brush), the color change, degrease hours, and whether hardware is replaced, plus your own labor hours and material costs. It prices doors, drawer fronts, face frames, and hardware separately, scales labor by finish method and extra coats, then returns the walk-away price and a bid price above your target margin — for this kitchen, not a generic one.
| What a flat price per door does | What this calculator does instead |
|---|---|
| Charges the same rate per door whether the kitchen has 8 drawer fronts or 24, even though drawer fronts and face-frame openings do not scale with the door count a homeowner counts. | Prices doors, drawer fronts, and face-frame openings as separate piece counts, so a kitchen with more drawers than doors is never quoted off a door-only rate. |
| Has no line for hardware remove-and-rehang, or for replacing hardware with new pulls and knobs on every piece. | Prices hardware labor per piece, and adds material cost per piece when hardware is replaced, so a kitchen swapping 114 pulls and knobs costs more than one reinstalling the originals. |
| Applies one rate regardless of finish method, even though on-site spray runs 28% more labor hours than a shop-spray booth on the same doors, and on-site brush runs 55% more. | Scales door, drawer, and opening hours by the finish method's own labor factor, so on-site brush work costs more than the same doors sprayed off-site in a booth. |
| Prices a dark-to-light color change the same as touching up the same family of color, even though dark-to-light needs a whole extra finish coat on every removable piece. | Adds extra-coat hours on doors and drawer fronts when the color change calls for one, so a dark-to-light kitchen is never quoted at the same-color rate. |
| Gives the painter a number to quote, not a number to check a quote against. | Reports the walk-away price and the dollar gap against what a flat per-door rate would have quoted the same job, so a shopped price can be scored against real cost before you commit to it. |
Two kitchens, the same door-blind rate
Using this calculator's own shipped presets:
| Job | This calculator's price | A flat $339.00/door rate, applied by door count alone | Gap |
|---|---|---|---|
| 10-door, 8-drawer galley, shop spray, same-family color, existing hardware reinstalled (the job this flat rate was built on) | $3,389.95 — $339.00/door | $3,389.95 (same job, same rate) | No gap: this is the one job the flat rate fits. |
| 30-door, 24-drawer, 26-opening kitchen, on-site brush, dark-to-light extra coat, 114 pieces of new hardware | $13,683.76 bid price; $10,262.82 break-even cost | $10,169.85 | The flat rate quotes $92.97 below this job's own break-even cost — before a dollar of profit — and $3,513.91 below the calculator's bid price. |
Both flat-rate quotes use the $339.00/door rate the 10-door galley's own price works out to. Applied to the 30-door kitchen's door count, that rate carries none of the on-site brush labor factor, the dark-to-light extra coat, the 16 extra drawer fronts and 17 extra openings, or the $912 of new hardware the bigger job actually needs — and it prices below what the job costs to complete. Run your own kitchen's numbers in the calculator to see where it falls.
A flat rate is not wrong because it is simple — it is wrong when it is applied outside the one kitchen it was built for, and nothing about a per-door number tells you when that has happened. This calculator does not know your local market; it replaces the arithmetic a flat rate skips.
Common questions
Why does a flat price per door get a cabinet refinishing quote wrong?
Because the cost driver is drawer fronts, face frames, hardware, finish method, and color change, not door count. A 30-door kitchen with 24 drawer fronts, on-site brush finishing, new hardware on 114 pieces, and a dark-to-light extra coat needs far more labor and material per door than a shop-sprayed 10-door galley in one color. A flat per-door rate charges every door the same regardless of what else the job carries.
What does a flat per-door rate usually leave out entirely?
Drawer fronts and face-frame openings, which do not scale with the door count a homeowner counts; hardware remove-and-rehang or replacement; the extra labor factor for on-site spray or brush work versus a shop spray booth; and the extra finish coat a dark-to-light color change needs. A per-door number has no line for any of them.
How big is the pricing gap in practice?
On this calculator's own shipped presets: a 10-door, 8-drawer galley, shop-sprayed in one color prices at $3,389.95 -- $339.00 a door. Applying that same $339.00-a-door rate to a 30-door, 24-drawer kitchen with on-site brush finishing, a dark-to-light extra coat, and 114 pieces of new hardware quotes $10,169.85 -- $92.97 below that job's own $10,262.82 break-even cost, before a dollar of profit, and $3,513.91 below the calculator's own $13,683.76 bid price.
Is a flat price per door ever the right way to quote?
For a narrow band of near-identical jobs -- same finish method, same color change, no hardware replacement, a similar drawer-to-door ratio -- a flat per-door rate can land close. The risk is applying it outside that band without noticing, because the rate does not know which kitchen it was built on and neither does the painter until the doors are actually counted.
Does this calculator know what paint or labor costs in my market?
No. It has no data on local paint invoices or labor rates. It takes the door, drawer, opening, and hardware counts, the finish method, color change, and degrease hours, plus the labor hours and material costs you enter, and turns that into a price for this job -- the arithmetic a flat per-door rate skips, not a market survey.
