Working capital is one of the first things a buyer or valuation professional examines, because working capital valuation shows whether a business can meet its short-term obligations and keep operating smoothly. Alexander Financial Solutions has more than 30 years of financial services industry experience, and understanding how a balance sheet affects what a company is worth is central to the advice we provide small and mid-size business owners. A business with strong earnings can still lose value if its working capital is poorly managed. This guide explains how working capital shapes business valuation, and what owners can do about it before a sale or review.

Why Working Capital Matters When a Business Is Valued

Working capital is the cash a business needs to fund day-to-day operations. It is the difference between current assets, such as cash, receivables and inventory, and current liabilities, such as payables and short-term debt. Buyers care about it because working capital valuation depends on the operating cash a business needs to keep running after closing, and they inherit that cash with the company.

A company that consistently runs short of working capital often has to rely on emergency borrowing, delayed supplier payments or rushed collections. Each of those creates risk a buyer will price in. A company with a healthy, predictable working capital position signals operational discipline, which tends to support a stronger valuation.

The Net Working Capital Formula Explained

Net working capital (NWC) is calculated as current assets minus current liabilities. Many valuation professionals strip out cash and debt-like items so the figure reflects only operating activity:

NWC = (Accounts Receivable + Inventory + Other Operating Current Assets) − (Accounts Payable + Accrued Liabilities + Other Operating Current Liabilities)

Excluding cash and interest-bearing debt keeps the calculation focused on how the business runs day to day. A positive NWC means the business has more operating assets than short-term obligations. A negative NWC is not always a problem, since some businesses collect from customers before they pay suppliers, but the trend matters and should be explained.

How Working Capital Feeds Into Discounted Cash Flow and Free Cash Flow

In a discounted cash flow (DCF) model, free cash flow to the firm is built from net operating profit after tax (NOPAT), plus non-cash charges such as depreciation and amortization, minus capital expenditures, minus the change in net working capital. That last line is where working capital does its damage or its good: an increase in NWC is a cash outflow, and a decrease is a cash inflow.

The mechanism is straightforward once you see it as a bridge. Suppose a company grows revenue and, to support that growth, its receivables and inventory rise by more than its payables. The change in NWC is positive, so free cash flow is reduced dollar for dollar. The income statement may show healthy profit, but the cash that profit generates is partly trapped on the balance sheet.

The reverse is equally important. A business that collects receivables faster, trims inventory, or stretches payables within reason releases cash, and that release shows up as a one-time boost to free cash flow. Valuation professionals are careful here: a release that comes from sustainable operating improvement supports value, while a release from liquidating inventory the business actually needs is not repeatable and should not be capitalized.

A common pattern in practice is to model the change in NWC as a percentage of the change in revenue, often called the incremental working capital ratio. If a company historically invests 12 cents of net working capital for every additional dollar of revenue, the forecast should reflect that.

Inflation adds a layer that most generic guides ignore. When input costs and selling prices rise, the dollar amount tied up in receivables and inventory rises even if physical volumes are flat. A company that historically needed $1.5 million of NWC at a given sales level may need $1.8 million at the same volume once prices rise. If the model holds the NWC ratio constant in dollar terms, it understates the reinvestment required and overstates free cash flow.

Watch out: a terminal value that assumes zero incremental working capital investment while also assuming perpetual revenue growth is internally inconsistent, and a sophisticated buyer will catch it in the first pass through the model.

Owners should expect buyers to rebuild this line from monthly data rather than accept the seller’s forecast. The defensible approach is to show historical NWC as a percentage of revenue over at least three years, explain any trend, and tie the forecast assumption to that history. SEC filings and 10-K working capital disclosures are a useful public reference for how comparable companies describe their working capital needs.

Working Capital Adjustments in M&A Transactions

Most acquisition agreements include a working capital adjustment. The purchase price is set on the assumption that the business will be delivered with a normal level of working capital at closing. If working capital at closing is higher or lower than that target, the price is adjusted up or down.

The target, often called the peg, is usually based on a trailing average of monthly working capital over several months. This protects both sides. The seller is not penalized for timing receivables collections, and the buyer is not left funding a shortfall the seller created by stripping cash out of the business before closing.

Disputes over these adjustments are common, usually because the definitions of working capital items were not clearly agreed in advance. Owners should ensure the calculation methodology is documented in the purchase agreement.

Normalized Working Capital, Peg Targets and Sector Benchmarks

Normalized working capital is the level a business needs to operate at its normal capacity, stripped of one-time distortions. Setting the peg, the target working capital figure written into the purchase agreement, requires that normalized number, because the closing adjustment is measured against it.

The normalization exercise is where deals are won and lost. A large customer paying early in the measurement month, a supplier delay that pushed payables into the next period, a one-time inventory build ahead of a product launch, or a year-end bonus accrual that will not recur, each of these moves the trailing average and, if left in, sets the peg too high or too low.

Sector benchmarks matter because a buyer will compare the target to peers whether or not the seller does. The most useful benchmarks are the cash conversion cycle and its components: days sales outstanding (DSO), days inventory outstanding (DIO), and days payables outstanding (DPO). A common pattern is that distributors and manufacturers carry meaningfully more inventory relative to sales than service businesses, while subscription and software businesses often bill in advance and run negative working capital by design.

Rather than rely on general rules of thumb, build the peer set from public comparables in the same industry and revenue band. Public company 10-K filings disclose receivables, inventory, and payables, which lets an owner compute DSO, DIO, and DPO for a handful of peers and present a range. Where public comparables do not exist, industry association surveys and the business’s own multi-year history are the defensible fallback. The point is not to hit a precise benchmark but to show the buyer that the peg is grounded in evidence rather than negotiation.

Distressed and turnaround situations need a different treatment, and this is where most guides stop short. When working capital is negative or volatile, a simple trailing average can produce a peg that is meaningless or even negative. The better approach is to model the working capital the business will need to operate under the buyer’s ownership at the forecast volume, not the level it happened to run at under the seller’s stressed conditions. That often means a forward-looking peg rather than a historical one, with a true-up mechanism if actual performance diverges.

Watch out: a peg built on a trailing average that includes a single unusually strong collections month will systematically favor the buyer at closing, because the seller will be measured against a target it cannot repeat.

Owners preparing for a sale should build the normalization schedule and the peer benchmark analysis before the buyer asks for them. Presenting both signals that the working capital position has been examined and defended, which reduces the chance of a late-stage adjustment dispute and supports a cleaner valuation.

Working Capital Management Strategies That Protect Valuation

Several practical steps can improve working capital before a sale or review:

• Tighten collections. Review aging receivables weekly and follow up promptly on overdue invoices. Shortening days sales outstanding releases cash without changing revenue.
• Manage inventory carefully. Identify slow-moving stock and reduce it. Excess inventory ties up cash and may need to be written down during due diligence.
• Negotiate supplier terms. Where possible, align payment timing with collections so the business is not paying suppliers faster than it is paid.
• Forecast cash needs. A rolling 13-week cash flow forecast helps owners spot shortfalls early and avoid emergency borrowing.

Invoice factoring is one tool some businesses use to convert receivables into cash quickly. It can help bridge a gap in working capital, though it has costs and affects how receivables appear on the balance sheet, so the effect on valuation should be considered.

The article lists practical steps owners can take to improve working capital before a sale or review.

Preparing Your Business for a Valuation Review

Start preparing at least a year before a planned sale or formal valuation. Gather monthly balance sheets for the past two to three years so you can show how working capital has moved over time. Be ready to explain seasonal swings, one-time items and any unusual payment terms.

Clean up the balance sheet. Remove obsolete inventory, resolve disputed receivables and confirm that accrued liabilities are recorded accurately. Buyers and valuation professionals will test these items, and errors reduce confidence in the rest of the financial statements.

Addressing working capital issues early gives you more options and a stronger position when valuation discussions begin.

Working capital is not just an accounting figure. It reflects how well a business runs, and it directly affects what buyers are willing to pay. Owners who understand the formula, manage the cycle carefully and prepare their records early are better placed to protect their valuation.
