Door Hardware Budget Calculator
Total door hardware cost from opening count and specification.
About this calculator
This calculator builds a full door-hardware budget for a project, starting from the number of openings and the ANSI/BHMA A156.2 grade you're targeting — BHMA's own published lock standard, which defines Grade 1 for heavy commercial traffic, Grade 2 for light commercial, and Grade 3 for residential. Each opening percentage — the share needing deadbolts, lever handlesets, panic/exit devices, and closers — is applied to the opening count to get counts by hardware type, and grade-specific unit prices (deadbolts, levers, and panic hardware all cost more at Grade 1 than Grade 3) are multiplied in. Hinges are priced per opening at grade-appropriate rates covering a typical three-hinge set, and a flat 15% is added on top of the lockset subtotal to cover miscellaneous items like kick plates, door stops, and weatherstripping that don't get their own line item.
Installation labor scales both with opening count and with grade — Grade 1 hardware is assumed to take longer to fit and adjust (45 minutes per opening) than Grade 3 (25 minutes) — at a flat $75/hour labor rate. The result is a total project cost, a cost-per-opening figure useful for comparing bids, and the typical manufacturer warranty length for the selected grade. Because the hardware-type percentages are entered independently of one another (an opening could in principle need both a deadbolt and panic hardware), don't expect the categories to sum neatly to 100% of openings, and treat the unit prices as commercial-grade averages rather than quotes from a specific manufacturer.

How to Use This Calculator
- Enter the number of door openings in the project and the ANSI/BHMA security grade required (1 = heavy commercial, 2 = light commercial, 3 = residential).
- Set the percentage of openings needing deadbolt locks, lever handle locksets, and panic/exit device hardware.
- Set the percentage of openings needing door closers.
- Review the total project cost, hardware cost, and installation labor, plus the cost per opening.
- Check the lockset, closer, and hinge cost breakdown and the typical warranty years for the selected grade.
How the result changes with Number of openings
| Number of openings | Total project cost |
|---|---|
| 10 | $3,613.00 |
| 15 | $5,548.00 |
| 30 | $10,839.00 |
| 50 | $18,064.00 |

Frequently Asked Questions
Do the deadbolt, lever, panic, and closer percentages need to add up to 100%?
No. Each percentage is applied independently to the total opening count, so an opening can be counted toward more than one hardware type — for example, an exterior door might need both a deadbolt and a closer. There's no cross-check forcing the categories to sum to the opening count, so don't expect them to add up neatly to 100%.
What's actually included in the 15% miscellaneous hardware line?
The calculator computes miscHardware as a flat 15% of the lockset subtotal (deadbolts plus levers plus panic hardware only — closers and hinges aren't included in that base). It's meant to stand in for items that don't get their own line, like kick plates, door stops, and weatherstripping, rather than being itemized separately.
Why does installation labor cost more per opening at Grade 1 than Grade 3, beyond the hardware price difference?
The calculator assigns a different labor-minutes-per-opening figure by grade — 45 minutes for Grade 1, 35 for Grade 2, and 25 for Grade 3 — multiplied by a flat $75/hour rate. That reflects the assumption that heavier-duty commercial hardware takes longer to fit, template, and adjust than lighter residential hardware, independent of the hardware's own price.
Why is the typical warranty so much longer at Grade 1 than Grade 3?
The calculator maps a fixed warranty length to each grade — 10 years at Grade 1, 5 at Grade 2, and 2 at Grade 3 — as a lookup rather than a calculation, reflecting the general industry pattern that heavier-duty commercial hardware ships with longer manufacturer warranties than residential-grade hardware. Those three grade tiers themselves come from ANSI/BHMA A156.2, the standard BHMA publishes for bored and preassembled locks, which is why the same Grade 1/2/3 labels show up consistently across manufacturers' pricing and warranty terms.
