A working capital loan deposits $5,000 to $250,000 within one to two business days and repays daily, weekly or monthly over a few months to two years at published APRs of roughly 15% to 60%, with short-term products sometimes quoting a factor rate instead. It wants six months in business and credit around 550, it is underwritten on deposits and its cost runs for the full term whether or not the money is still needed.
A business line of credit approves a limit of $10,000 to $250,000, opens in one to three business days and lets the business draw, repay and redraw as needed, with interest of roughly 10% to 60% APR — some lenders quoting a weekly fee — accruing only on the outstanding balance. It wants six to twelve months in business, credit around 600 and roughly $10,000 or more in monthly deposits, and lines often open small and grow.
The line is the better tool for any recurring need and for any business that qualifies, because the cost stops when the balance is repaid and the capacity is there next time. The working capital loan is the more available tool: it accepts a thinner file, funds a day faster and suits a one-time gap with a known end. Using a loan for a recurring need means reapplying and paying the full cost each time.
