How the comparison works
The gym charges every month plus a one-time initiation fee; the home gym charges once for the equipment plus a little every month for apps and maintenance. The gym total is the years times 12 times the monthly fee, plus the initiation fee. The home total is the equipment up front plus the years times 12 times the home monthly extras. The workouts are your visits a week times 52 times the years, and the cost per workout is each total divided by the workouts. The winner is whichever total is lower. The break-even is the equipment minus the initiation fee, divided by the gym fee minus the home monthly extras — the month the home gym's savings catch up with its up-front cost.
At the defaults — gym $45 a month, initiation $50, 4 visits a week, home equipment $1,200, home $10 a month, 5 years, 20 minutes of commuting — the gym costs $2,750.00 over 5 years and the home gym costs $1,800.00. Home wins by $950.00. Over 1,040 workouts that is $2.64 a workout for the gym and $1.73 for the home gym. Working out at home saves 69.33 hours of commuting a year.
| Case | Gym | Home | Winner | Gap | Workouts | Gym / workout | Home / workout | Break-even (mo) |
|---|
| Default ($45 gym, $50 initiation, 4/wk, $1,200 equipment, $10/mo home, 5 yr, 20 min) | $2,750.00 | $1,800.00 | Home wins | $950.00 | 1,040 | $2.64 | $1.73 | 32.86 |
| Gym fee $25 a month | $1,550.00 | $1,800.00 | Gym wins | $250.00 | 1,040 | $1.49 | $1.73 | 76.67 |
| Home equipment $500 | $2,750.00 | $1,100.00 | Home wins | $1,650.00 | 1,040 | $2.64 | $1.06 | 12.86 |
| 2 visits a week | $2,750.00 | $1,800.00 | Home wins | $950.00 | 520 | $5.29 | $3.46 | 32.86 |
| Home monthly extras $0 | $2,750.00 | $1,200.00 | Home wins | $1,550.00 | 1,040 | $2.64 | $1.15 | 25.56 |
| Gym fee $60 a month | $3,650.00 | $1,800.00 | Home wins | $1,850.00 | 1,040 | $3.51 | $1.73 | 23.00 |
The worked example, line by line
Setup: gym $45 a month, initiation $50, 4 visits a week, home equipment $1,200, home $10 a month, 5 years, commute 20 minutes a visit.
Line 1 — the gym total. 5 × 12 × $45 + $50 = $2,750.00.
Line 2 — the home total. $1,200 + 5 × 12 × $10 = $1,800.00.
Line 3 — the winner. $1,800.00 is less than $2,750.00, so home wins by $950.00.
Line 4 — the workouts. 4 × 52 × 5 = 1,040 workouts.
Line 5 — the cost per workout. $2,750.00 ÷ 1,040 = $2.64 for the gym, and $1,800.00 ÷ 1,040 = $1.73 for the home gym.
Line 6 — the break-even. ($1,200 − $50) ÷ ($45 − $10) = 32.86 months, so home pulls ahead in month 33. Rounding convention: all figures are computed from unrounded values and rounded only for display — money to cents, so a figure worked out from the rounded numbers can differ by a few cents from the figure shown.
Reverse: the break-even is 32.86 months — at month 32 the gym costs $1,490.00 against $1,520.00 for home (gym still ahead by $30.00), and at month 33 the gym costs $1,535.00 against $1,530.00 for home (home ahead by $5.00). In year one the gym costs $590.00 against $1,320.00 for home — the gym wins year one, because the home gym costs more up front.
Every branch, checked
Gym fee $25 a month: the gym costs $1,550.00 and gym wins by $250.00 — the flip, at $1.49 against $1.73 a workout. A cheap gym beats a home gym; the break-even stretches to 76.67 months. Home equipment $500: the home gym costs $1,100.00 and home wins by $1,650.00 — $2.64 against $1.06 a workout, and the break-even is 12.86 months.
2 visits a week: 520 workouts, and the gym costs $5.29 a workout against $3.46 for the home gym — home still wins by $950.00. How often you train changes the cost per workout, never the winner. Home monthly extras $0: the home gym costs $1,200.00 and home wins by $1,550.00 — $2.64 against $1.15 a workout, and the break-even is 25.56 months.
Gym fee $60 a month: the gym costs $3,650.00 and home wins by $1,850.00 — $3.51 against $1.73 a workout, and the break-even is 23.00 months. The gym fee is the lever that decides it: every $15 a month is $900.00 over 5 years.
Reverse — the other way round: the break-even is 32.86 months, so home pulls ahead in month 33; in year one the gym costs $590.00 against $1,320.00 for home; and working out at home saves 69.33 hours of commuting a year.
What the defaults assume
The model assumes the gym fee never rises, the home equipment never needs replacing, and the home monthly extras stay at $10 a month — no sales, no shipping, no accessories. It assumes you train the same number of times every week for the whole comparison, and the commute is the same every visit. It leaves out the training effect: a gym has machines, classes, and a coach, and a home gym has whatever you bought. It leaves out motivation: some people train more at a gym, some train more at home, and the workouts you actually do are the ones that count. With 0 visits a week the calculator asks for a real training schedule, because cost per workout needs a workout count. Rounding convention: all figures are computed from unrounded values and rounded only for display — money to cents, so a figure worked out from the rounded numbers can differ by a few cents from the figure shown.

Who uses this
- The member paying $45 a month: they learn home wins by $950.00 over 5 years — so they know the home gym costs $1.73 a workout against $2.64, and they check the year-one figures, $590.00 against $1,320.00, before deciding whether they will stick with it past month 33.
- The member on a $25 budget gym: they learn the gym wins by $250.00 — so they know the flip happens below a $45 fee, and they check the break-even, 76.67 months, before paying $1,200 for equipment they may not need.
- The buyer with $500 of equipment in mind: they learn home wins by $1,650.00 — so they know the break-even is 12.86 months, and they check the cost per workout, $1.06, before deciding whether $500 of kit covers the workouts they do.
- The commuter with a 20-minute drive: they learn working out at home saves 69.33 hours a year — so they know the time saving is worth as much as the $950.00, and they check the 2-visits-a-week figures, $5.29 against $3.46, before deciding how much the drive really costs them.
Accuracy & limitations
The math is exact for the numbers you enter: the gym total is the years times 12 times the monthly fee plus the initiation fee, the home total is the equipment plus the years times 12 times the home monthly extras, the workouts are visits a week times 52 times the years, the cost per workout is each total divided by the workouts, and the break-even is (equipment − initiation) divided by (gym fee − home monthly extras). What the model cannot do is know your real gym: check the fee, because gyms raise prices and charge annual fees on top of the monthly one, and check the equipment, because cheap kit can need replacing and good kit can last decades. It assumes the fee never rises and the equipment never breaks. It leaves out the training effect, the classes, the coach, and the motivation, which are the real reasons to pick one over the other.
