Travel and friction
Distance, parking, transit, crowding, and limited hours reduce practical attendance.
Lifestyle planning
Compare two gyms using joining fees, monthly dues, per-visit charges, a common horizon, and a realistic completed-visit plan.
GYM COST COMPARISON
For adults comparing two memberships that both meet minimum health, accessibility, location, equipment, and schedule requirements. The model separates joining, monthly, and visit-dependent charges and reports total and complete cost per entered visit.
GYM COST COMPARISON
The lower cost matters only after both facilities pass health suitability, equipment, staffing, cleanliness, accessibility, travel, hours, crowding, and cancellation requirements. Expected visits are a plan, not a prediction.

CURRENT CALCULATION PROCESS
V=vn; T_A=J_A+nM_A+Vc_A; T_B=J_B+nM_B+Vc_B; Delta=T_B-T_A
Expected monthly visits multiply the horizon to form one shared visit count. Each option adds joining fees, horizon dues, and per-visit charges. Cost per visit divides the complete total by visits rather than dues alone.

MODEL AND FORMULA
Expected monthly visits multiply the horizon to form one shared visit count. Each option adds joining fees, horizon dues, and per-visit charges. Cost per visit divides the complete total by visits rather than dues alone.
DEEPER DECISION ANALYSIS
Distance, parking, transit, crowding, and limited hours reduce practical attendance.
Notice, nonrefundable fees, and freeze rights differ.
Classes, pools, adaptive equipment, or staff support must be matched.
WORKED DECISION CASES
Gym B becomes cheaper only after a horizon longer than the user can maintain.
Gym A costs more but its lower travel friction supports the actual schedule.
TECHNICAL LANGUAGE
EVIDENCE AND DATA LINEAGE
Retain both dated agreements, tiers, joining and annual fees, dues, visit charges, taxes, cancellation and freeze provisions, hours, accessibility, equipment, travel routes, attendance calendar, horizon, and unrounded totals.

FREQUENTLY ASKED QUESTIONS
Home workouts, cancellations, and intentions do not consume facility access.
Add charges inside the horizon to the joining layer and document them.
Joining and monthly dues then determine the difference.
Yes when material; use a documented separate adjustment.
No; frequency follows health, recovery, and personal goals.
Only when both satisfy the same intended activity requirements.
