Startup Cost Calculator

First-year funding need from one-time setup plus recurring monthly costs.

What belongs in setup

Entity formation, licences, equipment, initial inventory, website build, branding, deposits, and the legal review you are tempted to skip. Inventory is usually the largest line for a product business — and the one most often underestimated.

The number founders get wrong

Almost nobody funds enough runway. Twelve months of recurring costs plus setup is the honest baseline; six months is a gamble that assumes revenue arrives immediately, which it rarely does.

Reducing first-year cost

  • Lease equipment before buying
  • Start with a smaller inventory buy and reorder sooner
  • Use contractors for non-core work until volume justifies hires
  • Negotiate annual software pricing only after proving you need it

Reality check

Compare the total against what you can raise or save without stress. If the number requires a loan you cannot service from projected cash flow, the plan needs to shrink — not the assumptions to stretch.

Frequently Asked Questions

How much runway should a startup fund?

12 months of operating costs is the common target; 18 for hardware or regulated industries.

Should I include my own salary?

Yes, at a modest but real figure — founders who skip it discover the gap later.

Does inventory count as a startup cost?

Yes, as a one-time line, though it recycles as you sell.
