Working Capital 101: How Much Do You Really Need to Run Your Business?

Working capital is the cash your business needs to cover day-to-day operations between when money goes out and when money comes back in. Get the number wrong on the low side and you create stress; get it wrong on the high side and you tie up capital that could be growing the business.

The simplest formula: working capital = (monthly operating expenses × cash conversion cycle in months) + a safety buffer. If your monthly expenses run $40,000 and your cash conversion cycle is 1.5 months, you need at least $60,000 just to keep the lights on while waiting for receivables.

The buffer matters. Most operators we fund target 1 to 3 months of operating expenses as a safety reserve on top of the working calculation. That cushion absorbs late payments, unexpected expenses, and slow seasons without forcing reactive decisions.

Where does the working capital come from? Ideally from operations — but in practice, growing businesses outrun their cash flow constantly. That's where business credit lines shine. A line of credit acts as a flexible working capital buffer, drawn only when needed and repaid as receivables come in.

Don't confuse working capital with growth capital. Working capital keeps you running. Growth capital funds new initiatives. They serve different jobs and should usually be sourced from different facilities.
