FAQ
Calculator hub questions
Which calculator should I use first?
Start with the change you are planning. Use the ramp, doorway, turning space, and grab bar tools for home access and bathroom safety, the cost tools to budget care, and the medication and supplies tools for day-to-day caregiving.
Are the results exact?
No. These are planning estimates based on what you enter. Confirm local building codes, get professional quotes for installation, and follow medical advice for medication and care decisions.
Do the access tools follow ADA rules?
The ramp, doorway, turning space, and grab bar calculators use widely cited ADA accessibility figures as a starting point. Local residential codes can differ, so verify before building.
Can I use these on a phone?
Yes. Every page uses large labels, mobile-friendly inputs, and clear result cards so you can use them at the parent's home or the hardware store.
