Door Hardware Cost Calculator
Prices hardware, where the requirements on a commercial door are quite different from a house.
Result
A planning estimate, not a quote. Access, the age of the equipment, what is found once it is opened up and local labour rates all move the real figure, sometimes a long way.

Time, the hardware and the call-out. Residential hardware is largely a matter of choice and finish: a handleset, a deadbolt, hinges and a strike, fitted to existing prep or with new boring. Commercial and multi-family work is where the requirements start. Hardware on an exit door has to allow egress without a key and often without tight grasping, which rules out some residential designs, and a door in a fire rated assembly needs listed hardware and a closer with positive latching. Those are code and listing requirements rather than specification preferences, and substituting attractive residential hardware onto a rated or exit door is a genuine compliance problem.
What moves the number
- Whether the door is residential, commercial, an exit, or part of a rated assembly.
- Existing prep, since matching an old bore pattern and backset is far quicker than new boring.
- Whether a closer is required, which adds hardware, adjustment and a return visit when it is set wrong.
- Keying, as keyed alike sets, master keying and rekeying are separate work from the hardware itself.
Where this one goes wrong
Lever handles rather than knobs, hardware that releases without a key from the egress side, and operating force limits are accessibility and life safety requirements on the doors they apply to, not upgrades. Fitting a keyed deadbolt requiring a key to exit onto a required exit door is both a code violation and a serious hazard, and it happens because a customer asked for it. On rated doors, listed hardware and an operating closer are part of what makes the assembly rated, so a propped or disconnected closer defeats it. Which rules apply depends on occupancy and the adopted code, so confirm rather than assume.
Before you quote
- Establish whether the door is an exit or part of a rated assembly before specifying.
- Match the existing bore and backset where reusing prep.
- Confirm a closer is fitted and adjusted where the assembly requires one.

Questions
About this calculator
Can I fit any lock I like on a commercial door?
No. Hardware on a required exit generally has to allow egress in a single motion without a key, and accessibility rules restrict designs needing tight grasping or high operating force. Doors in rated assemblies need listed hardware and a closer. Those apply by occupancy and adopted code rather than by preference.
Why are lever handles required in some buildings?
Because a lever can be operated without gripping and turning, which knobs require. Accessibility requirements in the buildings they cover reflect that. It is a requirement on those doors rather than an ergonomic upgrade, and it is one of the more commonly missed items on a commercial hardware schedule.
Is reusing the existing hardware prep cheaper?
Considerably, when the new hardware matches the bore diameter, backset and hinge locations. New boring and mortising on an installed door is careful work and easy to spoil. Checking the pattern before ordering is worth the few minutes it takes.
The formula
total = hours x people x rate + parts + call-out, then sales tax

A worked example
These are the figures the calculator opens with. Every number in the results column below is produced by the same calculation the page runs, so you can follow it through before putting your own figures in.
What goes in
| Input | Value |
|---|---|
| Hours on site | 16 h |
| People needed | 1 |
| Labour rate charged | $92 |
| Parts and materials | $4,200 |
| Call-out or diagnostic fee | $95 |
| Sales tax | 0% |
What comes out
| Result | Value |
|---|---|
| Estimated total main result | $5,767 |
| Labour | $1,472 |
| Before tax | $5,767 |
| Sales tax | $0 |
About $5,767: $1,472 of labour, $4,200 of parts and a $95 call-out.
How sensitive the answer is
Holding everything else steady and changing only labour rate charged, this is what happens to estimated total. It is worth knowing which of your inputs the answer actually hinges on, and which barely move it.
| Labour rate charged ($) | Estimated total |
|---|---|
| $46 | $5,031 |
| $69 | $5,399 |
| $92 example above | $5,767 |
| $138 | $6,503 |
| $184 | $7,239 |
Every other input is held at the example value while this one changes, which is not how a real job behaves. Treat it as a guide to which number matters most, not as five separate quotes.
