Marine, Shipbuilding & Boat Manufacturing calculator

Boat Build Cost Estimate Calculator

Estimate the total cost to build a boat or small vessel. Enter your material bill (hull, deck, hardware, systems), total direct labor hours, fully burdened labor rate, and subcontractor costs (engines, electronics, upholstery). The result provides a preliminary build cost for budgeting, pricing, and go/no-go decisions on new vessel programs.

What this calculator does

  • Estimate total boat build cost using material cost, direct labor hours, labor rate, subcontractor cost, and overhead/margin markup for preliminary vessel pricing and budgeting.
  • Use it when preparing a preliminary build budget or customer quote for a new vessel to ensure all major cost categories are captured before detailed estimating.
  • The result estimates total vessel build cost combining materials, direct labor, and subcontracted systems.

Formula used

  • Direct labor cost = total labor hours x burdened labor rate
  • Total build cost = material cost + direct labor cost + subcontractor cost

Inputs explained

  • Total material cost: Sum of all purchased materials: fiberglass, resin, core, hardware, plumbing, electrical, paint, adhesives, and raw stock.
  • Total direct labor hours: All hands-on production hours: layup, assembly, outfitting, wiring, plumbing, paint, and commissioning. Use historical data or calculator estimates.
  • Fully burdened labor rate: Includes wages, benefits, supervision, tools, facility allocation, and utilities. Typical boatbuilding: $45-$120/hr depending on region and skill mix.
  • Subcontractor and purchased systems cost: Engines, generators, electronics, upholstery, canvas, specialized fabrication, and other outsourced items installed by the yard.

How to use the result

  • Use it for preliminary budgets, customer quotes, program feasibility checks, and comparing build cost across vessel sizes or configurations.
  • Does not include profit margin, sales commission, transportation to customer, warranty reserves, or engineering/design hours. Add these as markup percentages separately for a selling price.

Common questions

  • What cost categories should I include in materials? All raw materials and components your team installs: fiberglass, resin, core material, gelcoat, hardware, fasteners, plumbing fittings, wire, paint, adhesives, lumber, and sheet metal.
  • How do I estimate labor hours for a new design? Use the Hull Layup Labor and Outfitting Labor calculators in this category, or scale from a similar completed vessel using a size ratio (new hull length / reference hull length) raised to the power of 2.5.
  • What should be in the subcontractor cost? Items you purchase complete and install: engines, transmissions, generators, electronics packages, upholstery, canvas, custom metalwork, and any outsourced systems integration.
  • How do I get from build cost to selling price? Add overhead allocation (10-25%), engineering/design amortization, warranty reserve (2-5%), sales/marketing (5-10%), and profit margin (8-15%) depending on market segment and volume.
