Estimates only. Assumptions are listed below, and you can change every input.

Equipment quotes are only part of the bill. By the time rubber flooring is installed over a proper subfloor, mirrors and lighting are in, and an electrician has run dedicated circuits for a treadmill and a mini split, the room often costs far more than the catalogue price of what stands in it. Owners who budget only for equipment tend to run out of money at the finishing stage, which is exactly where a luxury gym earns its name.

This estimator builds the budget from the bottom up. Flooring is priced from your room size and installed rate per square foot, equipment and finishes are entered as lump sums, a design fee is applied as a percentage of those hard costs, and a contingency is added on top of everything. The result is a planning total and a cost per square foot you can compare against contractor proposals.

How to use this tool

Enter the floor area of the room and the installed flooring rate your installer has quoted or you expect to pay.
Enter your equipment budget and a lump sum for mirrors, lighting, audio, electrical and ventilation work.
Choose how much designer involvement you want and set a contingency, then compare the total and cost per square foot with any proposals you have received.

What the math assumes

Flooring cost is simply room area multiplied by the installed rate you enter; no waste factor is added, so include waste in the rate if your installer quotes it separately.
Design fees are fixed at 0%, 5% or 12% of hard costs (flooring, equipment and finishes) depending on the option chosen; actual designer fees vary and may be quoted as a flat sum instead.
Contingency is applied to hard costs plus the design fee, at the percentage you enter.
Structural work, plumbing, permits, sales tax and financing costs are not included unless you add them to the finishes and systems figure.
All figures are entered in US dollars and treated as one-time costs; ongoing upkeep is not part of this estimate.

Frequently asked questions

Why does the estimator apply contingency to the design fee as well?

Because when hard costs rise, percentage based design fees rise with them. Applying contingency to both keeps the reserve consistent with how the final invoice will actually be calculated.

Is 10% contingency enough for a basement or garage conversion?

Conversions uncover more surprises than a finished room, from uneven slabs to inadequate electrical panels. Many owners raise the contingency to 15% or 20% for conversions and lower it for a room that is already finished.

Should the equipment budget include delivery and assembly?

Yes. Premium racks and machines are heavy, and white glove delivery with in-room assembly is often quoted separately. Including it in the equipment figure keeps the total honest.
