Working Capital Calculator — Measure Your Business's Operational Cash Buffer
Calculate working capital and the working capital ratio. Understand if your business has enough liquidity to cover short-term obligations.
A profitable business can still run out of cash. Working capital is the buffer that keeps day-to-day operations running — paying suppliers, making payroll, managing inventory — while you wait for customers to pay. Too little and you're constantly in crisis. Too much and you have idle cash that could be working harder. The CalcHub Working Capital Calculator gives you the number and the ratio.
The Formulas
Working Capital = Current Assets − Current Liabilities Working Capital Ratio (Current Ratio) = Current Assets / Current LiabilitiesCurrent assets: cash, accounts receivable (within 30–90 days), inventory, short-term investments
Current liabilities: accounts payable, accrued expenses, short-term debt, advance customer payments
Example: A Manufacturing Business
| Current Assets | Amount | Current Liabilities | Amount |
|---|---|---|---|
| Cash + bank balance | ₹8,00,000 | Accounts payable (suppliers) | ₹12,00,000 |
| Accounts receivable | ₹15,00,000 | Accrued salaries | ₹3,50,000 |
| Inventory (raw + finished) | ₹18,00,000 | Short-term loan repayment | ₹5,00,000 |
| Prepaid expenses | ₹1,00,000 | Customer advances | ₹2,00,000 |
| Total | ₹42,00,000 | Total | ₹22,50,000 |
What the Ratio Means
| Current Ratio | Interpretation |
|---|---|
| < 1.0 | Negative working capital — technically insolvent on short-term basis |
| 1.0 – 1.5 | Tight but manageable; limited buffer |
| 1.5 – 2.5 | Healthy range for most businesses |
| > 3.0 | May indicate underutilized assets or inefficient capital allocation |
The Cash Conversion Cycle
Working capital alone doesn't tell the full story — you need to know how fast it cycles. The cash conversion cycle (CCC) measures the days between paying for inventory and collecting from customers:
CCC = Days Inventory Outstanding + Days Sales Outstanding − Days Payable OutstandingA business with ₹50L in working capital but a 120-day CCC is effectively "trapped" — the cash is tied up in inventory and receivables for 4 months at a time. The same ₹50L with a 30-day CCC cycles 4x faster, supporting 4x more revenue.
How to Use the Calculator
- List your current assets with amounts
- List your current liabilities with amounts
- Get working capital (absolute) and current ratio
- See quick ratio (excluding inventory) for a more conservative liquidity check
Quick Ratio
The quick ratio (acid test) strips out inventory from current assets, since inventory can be hard to liquidate quickly:
Quick Ratio = (Current Assets − Inventory) / Current LiabilitiesFrom the example: (₹42L − ₹18L) / ₹22.5L = 1.07 — much lower, and more conservative. This company's liquidity depends heavily on the quality of their receivables.
Can a business have too much working capital?
Yes. Excess working capital often means cash is sitting idle in low-value inventory or slow-paying receivables that could otherwise be invested in growth. Businesses in capital-efficient industries like software intentionally maintain lean working capital — even negative working capital in some cases (SaaS businesses collecting annual subscriptions upfront have negative CCC).
What's negative working capital and is it bad?
Negative working capital (current liabilities > current assets) is normal for some businesses — Amazon, Walmart, and many subscription companies operate with negative working capital because they collect cash from customers before paying suppliers. For manufacturing or service businesses with long collection cycles, negative working capital is a serious warning sign.
How do I improve working capital without taking on more debt?
Speed up receivables: offer early payment discounts, tighten payment terms, chase invoices earlier. Slow down payables: negotiate longer terms with suppliers. Reduce inventory: cut slow-moving SKUs, implement just-in-time for fast movers. Each of these improves working capital without adding any debt.
