How Much Working Capital Do I Need to Start a Business?

Published June 2026

The Short Answer

Most new businesses need 3 to 6 months of operating expenses in working capital before opening, plus 10% to 20% contingency. The exact number depends on industry, fixed costs, and how long it takes to reach break-even revenue. Service businesses can launch with as little as $10,000 to $25,000. Brick-and-mortar retail typically needs $50,000 to $150,000. Restaurants and franchises often need $250,000 or more.

Why This Matters

Underfunded launches are the most common cause of small business failure inside the first 24 months. The SBA's own data shows that businesses with less than 3 months of working capital reserve fail at roughly twice the rate of those with 6+ months. A working capital loan, line of credit, or SBA 7(a) can close the gap between what you saved and what you actually need.
