Stair Lift vs. First-Floor Conversion Calculator

Compare two very different strategies on cost, useful life, and broader construction needs.

Planning inputsUpdates automatically

Stair layout

Curves and landings usually require custom rails.

First-floor conversion

Scope for creating daily living on one level.

Planning horizon

years

Used to include service and maintenance.

Lift annual service allowance

Use a local service-plan estimate when available.

Estimated result

Lift $8,300 · First floor $38,000

Modeled difference: $29,700. Compare usability and emergency egress too.

How to interpret the result

A stair lift may solve one route quickly; a first-floor zone can support more daily activities and future users.
Check transfer ability, emergency egress, power outages, and caregiver needs—not cost alone.

The tool applies this planning structure:

installed option + annual maintenance × planning years

Equipment configuration, structural support, electrical work, bath plumbing, and addition costs are site-specific.
