How do you calculate hardware kit cost?

Multiply openings by cost per opening by the scope percentage to get the included package cost, then add fixed keying, submittal, and packaging. For 100 openings at $45 each at 80% scope plus $250 fixed, the total is $3,850.

What does the scope percentage represent?

It is the share of each opening's full hardware schedule you are actually supplying. At 80% the $45-per-opening base becomes an effective $36 per opening, reflecting that you are providing most but not all of the hardware on the schedule.

Why is the effective cost per opening lower than the input?

Because the scope percentage scales it down. Here the $45 per-opening cost at 80% scope gives an effective $36 per opening before the fixed adder - $3,600 across 100 openings - which is the included package cost shown.

What goes into the fixed keying, submittal, or packaging cost?

One-time project charges that do not scale with opening count: keying and pinning labor, submittal preparation, special packaging, or master-key system setup. Entered here as $250 and added on top of the material total.

How do I pick a cost per opening?

Use a blended average across the opening types in the package - a simple passage set costs far less than a fire-rated opening with electrified hardware. The $45 default is a moderate commercial average; build it from your actual hardware schedule for accuracy.

Hardware kit cost vs installed hardware cost - what's the difference?

This tool covers material kit cost only. Installed cost adds the labor to mount hinges, locksets, closers, and access control at the opening, which is scheduled and priced separately from the $3,850 material figure.

Doors, Hardware & Access Control Manufacturing calculator

Hardware Kit Cost Calculator

Hardware kit cost is the total material cost to assemble door hardware kits for an opening package, scoped to only the portion of the hardware schedule you are supplying plus the fixed keying, submittal, and packaging charges. Estimators and project managers in door and hardware distribution use it to price a finish hardware bid and protect margin on partial-scope jobs. The scope percentage is the key control: on many commercial jobs you supply hinges, locksets, and closers but not everything on the schedule, so applying the full per-opening cost to every line overstates the bid. This calculator captures the scoped material cost and adds the fixed project charges that do not scale with opening count.

What this calculator does

Estimate the cost of hardware sets for door openings, including hinges, locksets, closers, exit devices, strikes, cylinders, thresholds, seals, fasteners, and access-control hardware.
Use it when hardware kit cost in doors, hardware and access control manufacturing is being put through a doors, hardware and access control manufacturing weighted-cost review.
It computes the included hardware package cost as openings times cost per opening times the scope percentage, then adds the fixed keying, submittal, and packaging cost.

Formula used

Included hardware package cost = hardware sets or openings kitted × hardware kit cost per opening × scheduled hardware scope included
Total hardware kit cost = included hardware package cost + fixed keying, submittal, or packaging cost

Inputs explained

Hardware sets or openings kitted:
Hardware kit cost per opening:
Scheduled hardware scope included:
Fixed keying, submittal, or packaging cost:

How to use the result

Use it when bidding a finish hardware package, validating a vendor quote, or pricing a partial-scope opening order.
It uses one blended cost per opening and one scope percentage, so it will not capture opening-by-opening hardware variation, freight, or price escalation on long-lead items.
