How to Use This Calculator

Select modification categories: bathroom, kitchen, entry & access, and stairway solutions.
Within each category, choose specific modifications (grab bars, walk-in shower, lever handles, ramp, stairlift).
Review total modification cost and cost by category.
Compare modification cost to the annual cost of assisted living to determine the break-even point.
Consult a Certified Aging in Place Specialist (CAPS) for site-specific recommendations.
