Download NowLabour is the cost a backyard builder most often forgets to price, and it dwarfs materials on any boat you have to pay someone to build. The labour cost calculator puts a number on that hidden line by estimating the hours a job implies from what you spend on materials, then valuing those hours at the rate you are paying or avoiding.
It leans on a rough trade heuristic that build hours scale with material cost, refined by a complexity multiplier so a simple refit and intricate custom joinery are not priced the same. From the estimated hours and an hourly rate it derives the labour cost and, crucially, the savings your own sweat retains versus hiring a professional.
Enter the material cost, the complexity and who is doing the work, and the calculator returns estimated hours, the labour value and what DIY or a mixed crew saves against a fully professional build.
Estimated Hours = Material Cost × 0.05 × Complexity Multiplier; Labour Cost = Hours × Hourly Rate; DIY Savings = Professional Cost − Actual Cost| Complexity | Multiplier | Typical Work |
|---|---|---|
| Low | 1.0 | Swap-out, simple panel |
| Moderate | 1.5 | Refit, systems, joinery |
| High | 2.5 | Custom build, fine finish |
| One-off / full refit | 2.5 and up | Many trades, unpredictable hours |
Complexity multipliers and what they imply.

The calculator converts material spend into implied hours using a rule of thumb that each dollar brings about five hundredths of an hour, then scales by a complexity multiplier and values the hours at a chosen rate. A $3,000 moderate job suggests 225 hours, which at $75 an hour is nearly $17,000 of labour, the number that shows what hiring out would cost.
Because skilled hours accumulate fast and are priced high, so on a professionally built boat labour routinely runs two to three times the material bill. The calculator makes that visible by turning your modest material spend into the large wage figure you avoid by building yourself, which is precisely why DIY boatbuilding saves money and why paid work is expensive.
Work where finish and fitting dominate rather than raw material, such as custom joinery, spray finishing, rigging and systems integration, priced at the 2.5 multiplier. A simple panel swap is low at 1.0, and a general refit sits at 1.5, so choose the tier where the difficulty and the hours, not the price of the parts, actually lie.
Not economically, though it costs no cash. Your hours have a wage value, and the calculator's DIY saving is the money you keep by supplying them yourself, which is real but finite: those are hours not spent on paid work, family or rest. Understanding the saving as avoided wages, not free value, is what makes the trade-off honest.
Often yes for the work you cannot afford to get wrong or simply dislike. The mixed option prices paying for a fraction of the hours, showing the cost of buying in a professional on the critical or tedious tasks while you do the rest, which is usually the smartest use of money and skill on a boat you want both finished and right.
A planning-grade approximation, not a quote. It captures the broad truth that labour tracks and multiplies material spend, but individual jobs vary with your speed, tools and the surprises that await inside any hull, so use the number to set a budget and weigh decisions, then confirm with a real yard estimate before paying anyone.
