The short answer
For a straight staircase, expect roughly $3,000–$15,000 installed. For a curved staircase (one with a turn, a landing, or a spiral), expect $10,000 and up, because the rail has to be manufactured to the exact shape of your stairs. Outdoor and heavy-duty models fall at the higher end of their range due to weatherproofing and capacity.
Those are real installed prices in the Minnesota market, not teaser numbers. Below is what moves the figure up or down.
What drives stair lift cost
| Factor | Effect on price |
|---|---|
| Straight vs. curved staircase | The single biggest factor: curved rails are custom-built |
| Indoor vs. outdoor | Outdoor models cost more for weatherproofing |
| New vs. used/refurbished | Reconditioned straight lifts save money |
| Weight capacity & seat options | Heavy-duty and power-swivel options add cost |
| Length of the staircase | Longer rails use more track |
