Stair Lift Cost Calculator
Estimate the installed cost of a residential stair lift from your stair run length and material (rail) and labor rates per foot.
How this calculator works
This estimates the installed cost of a residential stair lift based on the length of the stair run. It multiplies the stair run length by a rail material rate per foot, then multiplies the same length by a labor rate per foot, and adds the two together for a total.
Formula: Total cost = stair run length × rail material rate per ft + stair run length × labor rate per ft.
Worked example
A 14 ft stair run, $250/ft rail material, $100/ft labor:
- Rail material: 14 × $250 = $3,500
- Labor: 14 × $100 = $1,400
- Total estimated cost: $4,900
Notes
A straight stair lift is much cheaper than a curved-rail lift. Straight staircases can use standard rail sections, while a stairway with a landing or turn needs a custom-built curved rail, which raises both material and installation cost well above the straight-rail estimate.
This per-foot rate is a simplified planning number meant for comparing rough scenarios. Most stair lift companies quote a flat installed price after sending someone to your home to measure the staircase in person, so use this estimate as a starting point rather than a final number.
How to use
Enter the length of your stair run, then set a rail material rate and a labor rate per foot based on quotes for your stair type — straight or curved. Confirm with an in-home assessment before budgeting, since most installers price the job as a flat quote rather than a strict per-foot rate.
Estimates only. Actual cost depends on your region, material choice, and site conditions — get a contractor quote before budgeting.
Frequently asked questions
How much does a stair lift cost to install?
It depends mainly on the rail material cost and the labor to install it, both of which this calculator applies per foot of stair run. A straight staircase costs much less to fit than one with a landing or turn, so enter rates that match your stairway type for a more accurate estimate.
What is a stair run in this calculator?
The stair run is the total length, in feet, that the lift rail needs to travel along your staircase. It's the measurement used to scale both the rail material cost and the installation labor cost in this calculator.
Why is a curved stair lift so much more expensive than a straight one?
A straight stair lift uses standard rail sections that fit most straight staircases. A curved-rail lift has to be custom-built to match a stairway with a landing, turn, or bend, which requires custom measuring, fabrication, and a longer installation, all of which raise the cost well above a straight-rail system.
Is the per-foot rate what companies actually charge?
Not usually. This per-foot rate is a simplified planning number to help you compare rough scenarios. Most stair lift companies quote a flat installed price after sending someone to measure your staircase in person, so treat this as a starting estimate rather than a final quote.
