How Much Working Capital Does Your Business Actually Need?

A business can have $200,000 in receivables and still struggle to make a $30,000 payroll.

That’s why asking how much working capital a business has is not quite the same as asking how much it actually needs.

A contractor paying crews and suppliers 45 days before collecting a progress payment needs a different cash buffer than a retailer collecting most sales immediately.

The practical question is:

How much cash does your business need between the moment money starts leaving and the moment enough of it comes back?

That is the working capital gap owners need to understand.

Start with the cash cycle, not revenue

Revenue doesn’t tell you when money will be available.

Two businesses can generate $2 million a year and have completely different working capital requirements. One collects quickly and turns inventory fast. The other purchases materials upfront, runs payroll every two weeks and waits 45 to 60 days for customers to pay.

Same revenue. Different cash requirements.

Map your operating cycle.

When do you pay employees and suppliers? When is inventory purchased? When are GST/HST, payroll source deductions and other CRA obligations due?

Then determine when the cash associated with those expenses actually returns.

The distance between those dates is what the business has to finance.

Working capital on paper isn’t always cash you can use

The standard calculation is straightforward:

Current assets – current liabilities = working capital

If a company has $180,000 in current assets and $130,000 in current liabilities, it has $50,000 in working capital.

But that doesn’t mean $50,000 is sitting in the bank.

Some may be inventory. Some may be invoices customers won’t pay for another 45 days.

Those assets have value, but they aren’t necessarily liquid.

You cannot make Friday’s payroll with an invoice expected next month.

That’s why owners need to understand both working capital on the balance sheet and cash actually available during the operating cycle.

Calculate what has to leave before customers pay

Consider an Ontario contractor starting a commercial project.

Over the first month, the company expects to spend $38,000 on materials, $42,000 on payroll and another $12,000 on equipment, fuel and project costs.

That’s $92,000 leaving the business.

The first major progress payment isn’t expected until mid-next month.

The project may be profitable.

But profitability doesn’t fund those weeks.

Cash does.

The contractor needs enough liquidity to carry the project while continuing to meet obligations elsewhere in the business.

Growth can increase the gap

Working capital requirements often rise when business improves.

If that contractor wins two additional projects, another crew may need to be hired, materials ordered and equipment rented.

Expenses begin immediately.

Revenue arrives later.

Growth generates revenue eventually. It consumes cash first.

Before taking on substantially more work, calculate the cash required to deliver it—not only the revenue and margin it should produce.

Find the lowest point in the next 12 weeks

An eight-to-twelve-week cash forecast can reveal how much working capital the business actually needs.

Use the dates customers realistically pay, not simply the dates printed on invoices. Then map payroll, suppliers, rent, inventory purchases, equipment payments and CRA obligations.

Most importantly, find the lowest cash point.

You might have $150,000 coming in and $140,000 going out over eight weeks. That looks comfortable.

But if $70,000 has to leave before the largest customer payment arrives, you can still have a significant short-term gap.

The totals work. The calendar doesn’t.

Then leave room for normal business friction: a customer paying ten days late, an equipment repair or a supplier requiring a larger deposit.

A plan that only works when everything goes perfectly is already too tight.

When additional working capital makes sense

Sometimes the underlying business is healthy but available cash temporarily falls below what the operating cycle requires.

A confirmed contract may require materials before the first progress payment. Seasonal inventory may need to be purchased before peak sales. A large receivable may arrive after payroll and supplier payments are due.

Those are timing gaps.

When future cash flow is reasonably visible, additional working capital can provide room to bridge them. A merchant cash advance is one option businesses may consider for short-term requirements such as inventory, payroll, supplier payments or an essential repair.

But funding should start with two questions:

How much cash is actually missing?

What future cash flow is expected to close the gap?

If those answers aren’t clear, additional funding may simply postpone a larger problem.

Your number should change with your business

There is no universal working capital target.

If payroll increases, customers take longer to pay, inventory turns more slowly or the business takes on larger contracts, the amount of liquidity required changes.

Know how much cash has to leave before revenue comes back. Find the lowest point in the next eight to twelve weeks. Then leave enough room for the delays and expenses that routinely happen in a real business.

The right amount of working capital isn’t the biggest balance you can keep in the bank. It’s enough liquidity to keep a healthy business operating without every delayed payment becoming a problem.
