Cabinet Layout, Quantity and Cost Calculator
Create a preliminary base-and-upper cabinet module count from wall runs, appliance gaps, fillers, corners, and editable costs.
How to use the cabinets calculator
- Measure the actual project. Break irregular work into separate sections and record finished dimensions consistently.
- Enter the core measurements. The quick view focuses on project geometry; add or subtract sections where the calculator supports multiple areas.
- Review purchasing assumptions. Open Advanced inputs to replace example prices, waste, coverage, density, pack size, minimum order, or delivery assumptions with current project information.
- Calculate and verify. Review the formula, limitations, whole-unit rounding, product instructions, and supplier requirements before purchasing.
Key inputs covered: Cabinet module mode, Average standard base module width, Average standard upper module width, Custom base module width, Custom upper module width, Base cabinet example price, Upper cabinet example price, Installation example price, Wall run length, Appliance and sink gaps, and additional project-specific assumptions.
Result coverage: The cabinets calculator reports 7 separate quantities so the primary estimate and its supporting purchase or planning values can be checked together.
How the estimate works
Appliance gaps, fillers, and corner allowances are removed from each wall run; usable lengths are divided into entered base and upper module widths without overfilling the run.
A 12 ft wall less 3.5 ft of gaps and fillers leaves 8.5 ft for preliminary modules.
Assumptions, rounding, and limitations
Dimensions are treated as finished measurements. Only deductions and allowances entered above are included. Decimal measurements display to two places; purchase quantities round up when a whole container or piece is required.
- This is a preliminary module allowance, not a final kitchen design, order, or installation drawing.
- Corners, blind cabinets, door swings, fillers, panels, scribes, plumbing, electrical, ventilation, accessibility, and countertop support require a verified layout.
- Confirm each manufacturer's exact cabinet dimensions, nomenclature, pricing, and design rules.

Editorial process
BuildPlanCalc publishes the formula, editable assumptions, limitations, and supporting references so the estimate can be checked rather than treated as a black box. See the calculation and review methodology, or report a correction.
Frequently asked questions
Are the results exact?
No. Results are planning estimates based on the dimensions and assumptions entered. Confirm product coverage, site conditions, and ordering rules with the supplier.
