The Aging In Place Modification Calculator helps seniors and their families evaluate the financial viability of home modification projects designed to enhance accessibility and safety. By inputting the total cost of planned modifications, projected increases in home value, estimated annual savings from avoiding assisted living or injury-related expenses, and the number of years they plan to stay in their home, users can determine the break-even point and overall return on investment. This tool is valuable for informed decision-making when planning long-term, independent living adaptations.
