Working Capital Calculator

Current means convertible to cash, or due, within twelve months. Current assets: cash, marketplace payouts pending, accounts receivable, and inventory at cost. Current liabilities: supplier invoices, credit-card balances, sales tax collected but not remitted, loan payments due this year. Equipment and long-term debt stay out of both sides.

Between 1.5 and 2.0 is the comfortable range for most merchants. Below 1.0 means short-term obligations exceed short-term resources, a real liquidity risk. Well above 3.0 often signals capital sitting idle in excess inventory or an oversized cash pile that could be funding growth instead.

Temporarily, yes, especially for stores that collect from customers instantly and pay suppliers on terms, since cash arrives before bills do. But negative working capital removes all slack: one supplier demanding earlier payment, a platform payout hold, or a soft sales month can turn it into a genuine cash crisis.

Because inventory only becomes cash if it sells at full value, and distressed inventory rarely does. That is why analysts also compute the quick ratio: (current assets − inventory) ÷ current liabilities. If your working capital looks healthy but is mostly inventory, run the quick ratio too before trusting the cushion.

The working capital requirement is what day-to-day operations consume before sales turn back into cash: inventory plus receivables minus payables, projected at the volume you are planning for. A quick estimate for merchants comes from the cash conversion cycle: daily operating costs × cycle days. A store spending $2,000 a day with a 30-day cycle needs roughly $60,000 of working capital on hand, and the requirement scales with revenue — which is why fast-growing, profitable stores still need financing.
