How do I estimate assembly labor for a custom door order?

Use the Door Assembly Labor calculator with the specific prep and hardware operations the order requires. A hollow metal door with three hinge preps, a mortise lock prep, and a closer takes far more time than a slab with a single bore. Combine it with Hinge Prep Cycle Time and Lockset Assembly Throughput so your quoted hours reflect the actual prep count, not an average that overprices simple doors and underprices complex ones.

What does fire-rating certification testing cost per design?

The Fire-Rating Test Sample Cost calculator captures the sample doors built for the test lab, the lab fees, and the labor to prep and ship samples. Because ratings like 20, 45, 60, and 90 minute are tied to specific assemblies, each new configuration may need its own test. Amortize that cost across expected volume for the rated design so low-volume fire assemblies carry their real certification burden.

How do I price a hardware kit accurately across SKUs?

Use the Hardware Kit Cost calculator to roll up hinges, lockset, closer, strike, and fasteners at current component prices for each configuration. Pair it with the SKU Option Complexity Score so highly configurable orders reflect their picking and kitting overhead, not just component cost. Since hardware is often the largest material component in a door, a stale kit cost quietly erodes margin as component prices move.

How do I calculate lead time for custom door orders?

The Custom Order Lead Time calculator adds material procurement, slab fabrication, prep and assembly hours, finish coating cure, and any fire-rating or access control testing to your current queue. Custom finishes and long-lead hardware often dominate. Feeding the SKU Option Complexity Score into it lets you flag orders that will run long before you promise a date, keeping your quoted lead times realistic.

How much warranty reserve should I hold per door shipped?

The Warranty Return Rate calculator applies your historical return or field-failure rate to units shipped, so you accrue for warped slabs, finish defects, and hardware failures. Pair it with the Packaging Damage Reserve calculator, since transit damage on doors is a common return driver. Funding both per unit shipped keeps returns from hitting a later period unbudgeted and highlights which configurations return most.

How do I plan test workload for access control devices?

The Access Control Test Workload calculator sizes the functional and cycle testing each electronic lockset or reader needs before shipment, from power-up checks to credential reads and mechanical cycle counts. As access control mixes with mechanical door lines, this testing becomes a real capacity constraint. Use it to staff the test bench so certified devices do not bottleneck at final QC while mechanical doors flow through faster.

Best calculators in this category

Door Assembly Labor: Estimate labor hours to assemble door leaves, frames, lite kits, seals, hinges, lock preps, and hardware reinforcement for a production order or opening schedule.
Hardware Kit Cost: Estimate the cost of hardware sets for door openings, including hinges, locksets, closers, exit devices, strikes, cylinders, thresholds, seals, fasteners, and access-control hardware.
Fire-Rating Test Sample Cost: Estimate the sample, lab, and documentation cost for fire-rated door, frame, glazing, hardware, or opening assembly testing.
Lockset Assembly Throughput: Estimate good lockset, latch, cylinder, or electronic lock assemblies available per shift after line availability and functional-test yield.
Finish Coating Cost: Estimate coating, paint, stain, powder coat, anodized hardware finish, or special color cost for doors, frames, and hardware components.
Custom Order Lead Time: Estimate required inventory or order coverage for custom doors, frames, hardware sets, cylinders, finish options, or access-control components with long lead times.
Hinge Prep Cycle Time: Estimate machining labor for hinge mortises, reinforcements, screw holes, pivots, continuous hinges, and frame/door hinge preparations.
Door Slab Material Yield: Measure usable door slab, skin, stile/rail, core, veneer, or hollow-metal blank yield from the cut or fabrication population.
Packaging Damage Reserve: Estimate reserve for freight, jobsite, and handling damage to doors, frames, hardware kits, access-control devices, glass kits, thresholds, and finished openings.
Access Control Test Workload: Estimate test labor for electrified locks, card readers, strikes, request-to-exit devices, door contacts, operators, credentials, and access-control panels.
SKU Option Complexity Score: Score complexity risk from door sizes, handings, swings, fire ratings, finishes, frame depths, lock functions, keyways, readers, and hardware-set variations.
Warranty Return Rate: Calculate return rate for doors, frames, hinges, locksets, closers, exit devices, cylinders, seals, readers, or electrified hardware shipped or installed in the field.
