HOW TO USE IT
How to use the Wheelchair Ramp Installation Cost Calculator
- 1
Measure the rise first: The rise sets the ramp length at the code slope. Measure from the landing to the top of the step or threshold.
- 2
Apply the 1:12 slope: For every unit of rise you need twelve units of run. A taller rise means a longer ramp, more material and more support posts.
- 3
Wood vs aluminum: Wood ramps are cheaper but need footings, framing and maintenance. Aluminum ramps install faster, last longer and cost more per square foot.
- 4
Factor in permits and landings: A permit may be required, and landings at top and bottom are mandatory for safety. Include both in the bid.
THE MATH

What should I verify before using the result?
A 1:12 slope means 12 ft of ramp for every 1 ft of rise; measure rise before pricing.
Is this a final quote or design?
No. Use it as a planning estimate, then confirm measurements, local rates, product requirements, permits and jobsite conditions before bidding or building.
