Workshop business calculator

Model unit economics, cash runway, break-even and outsourcing with your own prices and costs. No promised sales, earnings or payback.

Reviewed September 25, 2026No account requiredMethod & evidence

Test the assumption, not a sales promise

Use the same shipping/revenue basis as your cost inputs.
A scenario you supply, not predicted demand.
Allocate fixed per-order fees separately in variable cost.
Materials, spoilage, packaging, shipping, paid labor and allocated fixed fees. Do not double-count.
Separate from cash payroll. Enter 0 explicitly if excluded.
Only costs not already included per unit.
After the owner-time allowance and allocated fixed costs. Margin is not markup.

Start with your own numbers

A high selling price is not the same as profit. Include sellable yield, fees, fixed costs and your own time. This tool never predicts how many customers you will get.

Zero is a valid entered cost; blank means you have not supplied the assumption.

Show formulas and assumptions
  • Cash contribution = price × (1 − percentage fees) − variable cash cost.
  • Monthly cash surplus = sellable units × contribution − monthly fixed cash cost.
  • Owner-time result subtracts the unpaid allowance separately. Do not include the same labor twice.
  • Break-even units round fixed cost ÷ positive contribution upward.
  • Target price = (variable cost + owner allowance + fixed cost ÷ units) ÷ (1 − fee rate − target margin), rounded upward to cents. Zero volume or an impossible margin makes it unavailable. With zero entered costs, the smallest supported positive price is $0.01; a zero price has no defined revenue margin.
  • Runway = cash remaining after setup ÷ positive monthly burn; an upfront gap must be funded first.
  • Outsource/own compares the same finished units and horizon. Payback needs positive repeated monthly cash savings.

No financing, tax effects, depreciation, residual value, delayed receipts or sales ramp are modeled. Seek suitable professional advice for business commitments.

Build the full setup budget

Carry the relevant model or configuration into this separate check. No purchase or installation approval is implied.

Ownership cost planner

Estimate recurring ownership spending from your own prices and intervals. Missing costs stay visible, and no filter lifespan is assumed.

Ownership costs beyond the machine

Map consumables, service, site costs, labor and downtime before buying. Use your own quotes and observed intervals, not promised operating costs.

Method, evidence and limitations

Original planning framework. Numeric results use only your entered assumptions and the stated formulas; examples are fictional. Checklists summarize your own records without independently verifying them. No prices, maintenance intervals, earnings or machine performance are assumed. Inputs stay in the page; no cloud save.

Manufacturer documents can change or disagree. These source links are unpaid references. Dates describe this page's review, not certification of every model or material. Report a correction · Editorial standard.
