Example Scenario

First Business Launch

A founder estimates setup costs, monthly operating costs, revenue ramp, and a cash buffer. The calculator reveals the total funding needed to reach a stable operating state.

Technical Notes

One-time setup includes registration, equipment, branding, website, deposits, and initial inventory.

Operating costs during ramp-up assume costs run before full revenue arrives.

The reserve buffer covers unexpected expenses and slower-than-expected revenue growth.

Recommended startup capital is setup costs plus ramp-up operating costs plus the reserve buffer.

Break-even monthly revenue is the monthly operating cost that revenue must cover to stop losing money.

The first-year total includes setup costs plus a full year of operating costs.
