IHRSA Industry Data Survey (monthly attrition benchmarks across big-box

Gym Member Lifetime Value (LTV) Calculator

Screen the unit economics of a gym, boutique studio, or wellness facility using the standard SaaS-style LTV formula adapted for monthly-recurring fitness: LTV per member equals ARPU times gross margin times the perpetuity factor of one over monthly churn. Reports LTV per member, total gross LTV across the active member base, expected member tenure, monthly contribution per member, CAC payback in months, the LTV-to-CAC ratio with a health flag (STRONG, HEALTHY, WARNING, UNHEALTHY) calibrated to the 3-to-1 industry threshold and the 5-to-1 over-investment threshold, current MRR, projected 12-month MRR under compounding net member growth, and projected ARR. Industry benchmarks drawn from the IHRSA Industry Data Survey (4-7% monthly churn, ten-year average), ClubIntel operator benchmark reports, and the canonical SaaS LTV references (David Skok, OpenView Partners). Tool, not advice — for financial planning decisions tied to facility valuation, debt-service coverage, or operator earn-outs, work with a credentialed CFO or financial planner who can layer cohort curves and ancillary revenue onto this baseline.

ClubIntel Annual Boutique Fitness Studio Operator Report (drop-in pricing distributions

Boutique Class-Pack Pricing Calculator

Build the boutique-studio class-pack pricing ladder from a cost-plus floor and a competitive-set anchor. Computes the per-class floor at the target gross margin, the recommended drop-in price (cost-plus floor clipped against comp-set median), the recommended 5-pack, 10-pack, and 20-pack prices at standard boutique discount tiers (10% / 15% / 25%), the recommended unlimited monthly price at typical boutique attendance volume, the per-class effective price for each pack tier, and the breakeven attendance per pack against the drop-in alternative. Reports a pricing-position flag (BELOW_COMP_SET / ALIGNED / PREMIUM / OVERPRICED) so operators can sanity-check whether the cost-plus floor sits inside the defensible competitive band. Industry benchmarks drawn from the ClubIntel boutique studio operator reports, IHRSA Industry Data Survey segmentation, and ClassPass marketplace pricing data. Tool, not advice — for pricing decisions tied to elasticity testing, multi-location rollout, or franchise pricing covenants, work with a credentialed pricing consultant who can layer demand curves and segment mix onto this baseline.

ClubIntel Annual PT Operator Report (per-session pricing distributions across 1:1

Personal Training Session Pricing Calculator

Price personal-training sessions across the standard delivery formats — one-on-one, 2:1 semi-private, 3:1 semi-private, and small-group (4-8 clients) — from the fully-loaded trainer hourly cost, facility rent per PT hour, target gross margin, and target trainer take-home per session. Computes total per-hour cost, recommended 1:1 session price from the cost-plus floor, recommended total session prices for the multi-client formats using the standard boutique PT multipliers (1.5x for 2:1, 1.75x for 3:1, 2.25x for small-group), per-client effective price for each format, trainer take-home from the 1:1 session with a target-comparison flag (MEETS_TARGET / BELOW_TARGET), and breakeven sessions per week with a productivity flag (PRODUCTIVE / UNDER_BOOKED) against the 25-sessions-per-week target. Industry benchmarks drawn from ClubIntel personal-training operator reports, IHRSA Industry Data Survey ancillary-revenue segmentation, NASM and ACE compensation surveys, and the IDEA Personal Trainer compensation studies. Tool, not advice — for compensation-structure decisions, multi-tier trainer pricing, or PT-program design tied to club retention, work with a credentialed PT-business consultant or operator CFO.
