What decides your number
Two deck projects the same size can land thousands apart. Three things move the total more than anything else, and the first one does most of the work.
TradesMetrics prices every job at one of four finish levels. This single choice is what stretches the sell price from $22,000 to $37,000.
Ranges below are what each finish level typically sells for, at normal access.
Basic
$22-27kStandard
$25-30kPremium
$27-33kLuxury
$31-37k2 · Site access
An easy ground-floor deck with parking is cheaper to work in than a tight upper-floor space with stairs and no loading. Difficult access adds labor hours for moving materials and debris.
3 · Where in VI
Local trade wages and material costs set the baseline, and US Virgin Islands's larger metros run higher than its smaller cities. The same deck costs more in Charlotte Amalie, Christiansted or Frederiksted than in Cruz Bay, Kingshill, Anna's Retreat or other cities in VI.
Where the money goes, and why markup is not margin
Here is a standard-finish, normal-access US Virgin Islands deck, milestone by milestone, then your cost, markup and price broken out by type. Ballpark for planning, not a line-item quote.
| Milestone | Lab | Mat | Equ | Sub | Fee | Total |
|---|---|---|---|---|---|---|
| Permits & Fees | - | - | - | - | $868 | $868 |
| Site Prep & Demolition | - | - | - | $560 | - | $560 |
| Exterior Works & Site | - | - | - | $21,252 | - | $21,252 |
| Closeout | $720 | - | - | $560 | - | $1,280 |
| Contingency | - | - | - | - | - | $0 |
| Your cost | $720 | $0 | $0 | $22,372 | $868 | $23,960 |
| Markup | $28840% | $010% | $010% | $2,23710% | $00% | $2,525~10.5% |
| Price | $1,008 | $0 | $0 | $24,609 | $868 | $26,485 |
Contingency is shown at $0 here. When you price a real job, account for it, typically 5 to 10% of cost.
Price and cost part ways at markup: the job's 10.5% markup over cost is only a 9.5% margin of the price. It's the same profit dollars measured two ways — markup divides by your cost, margin by the larger price — so the margin is always the smaller number. Underprice that gap and the bid quietly loses money.

Common questions
- How much does a deck build cost in US Virgin Islands in 2026?
- A standard deck build in US Virgin Islands costs a contractor about $23,960 to build, and at TradesMetrics default markups typically sells for about $26,485. See the ranges above for basic through luxury and easy through difficult access.
- What is the difference between basic, standard, premium and luxury?
- Basic is a full-scope deck build at entry finish: budget materials and standard fixtures, same layout. Standard steps up to mid-range materials and finishes with minor changes. Premium is semi-custom with high-end finishes and some layout change. Luxury is full custom: reworked layout and top-tier materials throughout.
- How much does a deck build cost per square foot?
- Most deck projects are priced by scope rather than by the square foot.
- Why does the price vary so much?
- For a US Virgin Islands deck, finish level is the biggest driver, then site access and where in the state you build. Trade wages vary by region, and larger metros run higher than smaller cities.
- Is this an estimate or a quote?
- It is an estimate: a planning range built from regional cost data and your finish level. A quote is a firm price a contractor gives after seeing the site and final selections. Use the estimate to set a budget, then get a quote to lock it in.
- How much should I budget for surprises?
- The base already reflects typical job costs, so you do not need a routine overrun buffer. Add an optional contingency (commonly 5 to 15 percent) only when a job carries real unknowns, like old wiring or plumbing you cannot see until the work opens up.
- What is the difference between markup and margin?
- On a standard deck priced with TradesMetrics default markups, the work costs you $23,960 and the client pays $26,485, the Price total of the table. That $2,525 difference is the same profit measured two ways: 10.5 percent of your cost (markup) but only 9.5 percent of the price (margin), because margin divides the same dollars by the larger price. The base already reflects typical job costs, so no contingency is added by default.
- What is the real cost of labor on a job?
- Base wage is not the real cost. Once you add payroll taxes, workers comp, benefits and paid time off, a worker costs 35 to 50 percent more than their hourly wage. Estimating off base wage is a common way to lose money.
