Working capital calculator

Working capital is the difference between a business’s current assets and current liabilities.

Working capital = Current assets – Current liabilities

This figure shows how much cash and liquid resources your business has available for day-to-day operations.

A positive working capital indicates that your business can comfortably meet its short-term obligations, while a negative figure may suggest cash flow issues.

Why working capital matters

1) Supports daily operations

Working capital helps a business pay for everyday expenses such as:

• Wages and salaries
• Rent and utilities
• Supplier payments
• Inventory purchases
• Marketing costs

Without enough working capital, even profitable businesses can struggle to keep running smoothly.

2) Improves cash flow management

A healthy level of working capital means the business has enough liquid funds to cover short-term bills when they fall due.

This reduces the risk of:

• Missed payments
• Late fees
• Supplier issues
• Cash shortages

3) Shows financial stability

Investors, lenders, and business owners often use working capital as a key measure of financial strength.

Positive working capital generally suggests that the business is in a stable position.

Negative working capital may signal liquidity problems or potential financial stress.

4) Helps business growth

Growth often requires upfront spending on stock, staffing, equipment, or expansion.

Strong working capital gives businesses the flexibility to invest in these opportunities without relying heavily on borrowing.

5) Builds supplier and lender confidence

Suppliers and lenders are more likely to trust businesses that can meet short-term obligations consistently.

Good working capital can help secure:

• Better credit terms
• Improved supplier relationships
• Easier access to finance
