Attendance feasibility
Work, caregiving, transit, hours, and health can limit usable visits.
Lifestyle planning
Build a protected gym-membership budget from joining fees, dues, annual charges, classes, travel, contingency, horizon, and dedicated savings.
GYM MEMBERSHIP BUDGET
For adults planning the cash commitment of a gym membership. The model extends dues, optional classes, and travel across a horizon; adds joining and annual fees once; applies one explicit contingency; and compares the protected total with dedicated fitness savings.
GYM MEMBERSHIP BUDGET
Use the protected total to test budget fit, but review health suitability, safety, accessibility, travel time, cancellation rights, and realistic attendance separately. Savings reduce the gap, not the cost.

R=(M+C+V)n; Base=J+F+R; Protected=Base(1+u); Gap=max(0,Protected-S)
Monthly dues, classes, and incremental travel extend across the horizon. Initiation and one annual fee are added once. One contingency applies after the base sum, and savings reduce only the funding gap.

DEEPER DECISION ANALYSIS
Work, caregiving, transit, hours, and health can limit usable visits.
Notice periods, freezes, annual fees, and payment authorization change exit cost.
Equipment, instruction, air quality, and accommodations determine suitability.
WORKED DECISION CASES
Higher dues are partly offset by lower travel and realistic attendance.
Transit and classes make the complete total exceed the target.
