How do you calculate hardware kit cost?

Multiply the number of kits by the cost per kit and by the allocation percentage, then add fixed handling. With 120 kits at $18.75, allocated 100 percent, plus $165 handling, the total is $2,415.

What does the allocation percentage do?

It assigns a share of a bulk hardware buy to one order. At 100 percent the full per-kit cost lands on this job; at 60 percent only 60 percent of the hardware cost is charged here and the rest carries to other orders.

What is the cost per kit in the example?

Divide the $2,415 total by 120 kits to get $20.125 per kit. That is higher than the $18.75 hardware-only figure because it absorbs the $165 fixed handling across the batch.

Should kitting labor go in cost per kit or fixed handling?

Put per-unit assembly of each bag in the cost per kit, and put one-time setup such as building the kitting station or counting bins in fixed handling. Keep them separate so you can see which scales with volume.

How do I quote hardware for RTA furniture?

Sum every hinge, cam lock, dowel, and screw into one cost per kit, then run this calculator. RTA hardware counts are deceptively high, so a per-piece bill of materials feeding the per-kit cost prevents underquoting.

What is a good hardware cost per kit?

It depends entirely on the product, but track it against your selling price as a percentage. For most contract furniture, hardware should be a predictable single-digit-to-low-teens percent of unit cost; spikes usually mean a SKU substitution or a missed bulk discount.

Furniture, Fixtures & Interior Products calculator

Hardware kit cost Calculator

Hardware kit cost is the loaded cost of the hinges, slides, connectors, fasteners, and pulls that ship with each furniture or fixture unit, plus the kitting and handling labor to assemble those bags. Purchasing managers and estimators use it to quote knock-down furniture and store fixtures accurately, because hardware is easy to under-count when a single cabinet can carry dozens of small parts. The allocation field matters when a bulk hardware buy is split across several orders, so each job carries only its fair share. Getting this right protects margin on high-volume RTA and contract furniture work where pennies per kit add up fast.

What this calculator does

Estimate the installed or kitted cost of hinges, drawer slides, pulls, brackets, glides, fasteners, locks, and specialty hardware.
Use it when procurement, estimating, or assembly needs a defensible hardware cost per cabinet, fixture, display, or interior product kit.
It computes total hardware kit cost and cost per kit by applying an order allocation percentage to the per-kit hardware cost and adding fixed handling.

Formula used

Variable hardware kit cost = furniture or fixture hardware kits × hardware cost per kit × hardware allocation to this order
Total hardware kit cost = variable cost + fixed hardware handling cost

Inputs explained

Furniture or fixture hardware kits:
Hardware cost per kit:
Hardware allocation to this order:
Fixed hardware handling cost:

How to use the result

Use it when quoting knock-down or contract furniture, allocating a bulk hardware purchase across orders, or checking kitting cost per unit.
It treats hardware cost per kit as a single blended figure; if kits differ by SKU or finish, run each variant separately or use a weighted average.

Current U.S. benchmarks

The producer price index for lumber and wood products stands at 280.994 (BLS, May 2026), up 4.2% from a year earlier. Quotes priced off last quarter's material cost miss this move.
The U.S. has 14,378 furniture and related products establishments employing about 355,594 workers (Census County Business Patterns, 2023).
