The spa
Start from a common job, then replace every figure with your takeoff. Changing size, access, or power never overwrites a rate you already typed. This prices a portable spa hang — not a pool plaster, and not a water-heater swap.
Your crew rates
A $48/h installer loaded at 34% is $64.32. Quoting the raw wage on a published $499-setup special is how a swim spa that needs a crane and sixty feet of trench that looked fine turns into a two-day loss after the first stuck disconnect. Set spa unit cost to 0 if you are pricing delivery and setup only.

Where the hours go
Where the cost goes
Transparent arithmetic from your own inputs. Starting hours and material rates are common ballpark figures, not an industry standard or an electrical design — replace them with your own takeoff.
Hand the customer a proposal
The price above is for you. This is the page you print or save as a PDF and give to the customer — your details, their details, the scope, the deposit split, and a line for them to sign. Your business details are saved on this device so you only type them once; the customer’s details are never saved.
Everything on the printed page is text you typed or a number this calculator worked out. It contains no warranty, lien, or cancellation wording — those depend on your jurisdiction and your contract, and this tool is not the place to invent them.
Common questions
Why can a dealer advertise a “$499 delivery and setup” special?
Because that price is written around one specific job, and it is the first preset here: a compact four-person spa, a driveway or patio drop with no crane, an existing 50A GFCI ten feet away, and an existing pad. That job really is close to $499 in setup labor. It stops being that job the moment the tub goes through a tight backyard gate, needs a crane over a fence, or has to wait on a new circuit — none of which the flat-fee flyer prices separately.
Why does going through a gate or over a fence change the price?
Access is billed on its own line, separate from the set itself. A through-gate or tight-path delivery adds 1.8 hours of access labor. A crane or boom over a fence or house adds 3.6 hours and a separate crane/boom fee — the only access tier that bills a rig at all. A driveway or patio drop bills zero access hours, which is most of why it can be the cheap special.
When does the calculator bill for the electrical circuit?
Only when the power scope is not “existing.” An existing 50A GFCI within 10 feet bills no circuit hours or material at all. A new 50A run bills the circuit kit plus a per-foot rate across the circuit footage you enter. A new 60A run adds the same per-foot billing plus a flat 1.2 hours for the disconnect itself — the half-day adder a coupon price never mentions.
How does spa size change the price beyond the unit itself?
Size sets both the set-hours and a multiplier on the spa’s unit cost, not just a bigger box. A compact 4-person spa starts at 2.5 set hours and a 1× cost multiplier. A mid 6-person tub is 3.4 hours and 1.35×. A large swim spa is 5.2 hours and 2.1× — more than double the compact tub’s material cost before a single extra (pad, haul-away, crane) is added.
What do the pad, haul-away, cover lift, steps, and gas extras add?
Each is its own toggle with its own hours and material cost, billed only when checked: a new concrete pad, hauling away an old tub, a cover lift, steps, and a gas line or conversion. None of them ride along with the base set price, so a mid-size tub with a new pad and haul-away can cost more than a large tub dropped on an existing pad with nothing to remove.
