The working capital peg is a contractual mechanism that establishes the expected level of current assets and liabilities a business must maintain at closing. It functions as a bridge to ensure the buyer receives a functional operation while preventing the seller from stripping assets before the transaction concludes.
The short answer
- A working capital peg prevents asset stripping and ensures the buyer receives a functional business with sufficient operational resources.
- Target working capital is calculated using a multi-year average of monthly balances to account for seasonal fluctuations in inventory and receivables.
- Inventory that is obsolete or stagnant should be written off or liquidated before due diligence begins to prevent purchase price disputes.
- Closing adjustments reconcile the actual balance sheet against the agreed peg, ensuring the final price remains neutral to short-term fluctuations.
01What is a working capital peg?
In a business transaction, the purchase price assumes a normalized level of operational liquidity. Working capital is the difference between current assets like inventory and receivables, and current liabilities like accounts payable. The peg is the specific dollar figure the parties agree represents the normal, day-to-day balance of these accounts for that company. Establishing this figure early in the deal process helps both parties align on what constitutes a healthy, ongoing operation for the business entity.
When the deal closes, the buyer and seller compare the actual working capital on the balance sheet to the agreed peg. If the company maintains more capital than the peg, the buyer pays the seller the difference. If it has less, the seller owes the buyer or accepts a purchase price reduction. This protects both sides from fluctuations in inventory or payables during the final 90 days of ownership. It prevents sellers from delaying bill payments to artificially inflate cash holdings.
Without this mechanism, a seller might stop purchasing necessary inventory to boost personal distributions before handing over the keys. The peg anchors the business to a verifiable standard, ensuring the buyer takes over a functional operation that sustains itself on day one. Buyers typically model their acquisition financing, such as a 5-year bank note, around the expectation that the business carries the necessary assets to generate consistent monthly free cash flow.
02How is the net working capital target calculated?
The target is typically calculated by averaging the company month-end working capital over the preceding 24 months. This approach accounts for seasonality, as many businesses experience swings in inventory or receivable balances depending on the time of year. Using a 2-year average smooths out these cycles and provides a fair baseline for both buyer and seller. You must exclude non-operating items, such as idle cash or personal debt, to ensure an apples-to-apples comparison of true operational needs.
Sellers should analyze historical balance sheets to identify the true, normalized operating requirements of the business. You must adjust for non-operating items, such as cash held in the business that is not required for daily tasks or debt-like items that inflate current liabilities. This level of rigor creates a transparent comparison. If your average monthly working capital is $250,000, your peg should reflect that reality rather than a speculative number derived from a single good month.
Once you establish the average, you often include seasonal adjustments to reflect the specific month in which the deal closes. If you sell a retail business, the working capital needed in October before the holiday rush is 40% higher than the amount needed in February. A simple 12-month average without seasonality adjustments leads to an unfair result. Define these monthly variances in your letter of intent to keep the process grounded in evidence rather than negotiation.
03Does the business sale price include inventory?
The sale price includes the inventory required to operate at a normal capacity, as defined by the working capital peg. If your inventory levels at the time of closing are 10% higher than your historical average, the buyer effectively purchases that excess inventory as a dollar-for-dollar addition to the purchase price. Conversely, if levels fall below the threshold, you sell a less-resourced operation, and the price adjusts downward to compensate the buyer for the missing working capital assets.
Inventory management is a common source of friction in deals. You must categorize inventory as saleable or obsolete before the deal begins. Obsolete inventory is often excluded from the calculation entirely because it provides no value to the buyer. You should liquidate or write off stagnant inventory well before a buyer begins due diligence to avoid these negotiations. A clean warehouse signals that you have managed the business with an eye toward future value rather than short-term gain.
Buyers want to ensure they do not overpay for stock that is dusty, damaged, or slow-moving. A clear inventory policy agreed upon in the letter of intent sets the stage for how these items contribute to or subtract from the final price. Treat inventory as a productive asset rather than a warehouse cost. If you hold more than 3 months of inventory on hand, be prepared to justify that level as essential to your specific supply chain cycle.
04What happens when the actual working capital differs from the peg?
Post-closing adjustments are a standard component of the purchase agreement. After the closing date, the buyer and seller reconcile the actual working capital against the agreed-upon peg using a final closing balance sheet. This process takes 30 to 60 days depending on the company size and the complexity of the internal accounting. Both parties rely on this final review to ensure the business transition occurs on the agreed financial terms and that no hidden asset drain occurred.
If the calculation shows a shortfall, the seller owes the buyer the difference. In many deals, this is settled through an escrow account established at closing. A portion of the proceeds, often 5% of the total purchase price, is held back to cover potential adjustments. This provides the buyer with recourse if the business arrives with fewer resources than represented in the initial diligence. It creates accountability for the seller during the transition weeks.
If the calculation shows a surplus, the buyer pays the seller the additional amount. This ensures the seller is compensated for cash or inventory invested in the business during the final transition period. The goal remains neutrality. Neither the buyer nor the seller should gain or lose value based on how the company short-term assets shift in the final weeks. Neutrality respects the ownership context, whether you are a founder or an investor.
05How can you minimize disputes over the peg?
The most effective way to prevent arguments is to define the calculation methodology early. Use the same accounting firm to review the historical data that you intend to use for the closing balance sheet. If your accounting methods have changed significantly over the last 2 years, you must normalize the historical statements to match current practices. Transparency prevents the buyer from making negative assumptions about your business practices and helps maintain trust during the delicate diligence phase of a transaction.
Exclude unusual, one-time expenses or owner-related liabilities from the calculation. If you have been running personal expenses through the business, these must be stripped out so they do not impact the working capital peg. Buyers are wary of unclear balance sheets, so clean, consistent financial reporting serves as your best defense against an aggressive buyer-side negotiation. When your financial data is clear, you reduce the time required for due diligence by weeks.
Be transparent about how seasonality impacts your business. Presenting a report that shows the month-by-month variation in working capital over the last 3 years removes the mystery. When you provide evidence upfront, you control the narrative rather than forcing the buyer to build their own model based on incomplete information. Providing a clear, documented path to the peg keeps your focus on the core goal of completing a successful transaction.

Questions people ask about this
What is the typical timeframe for a working capital calculation?
The target is typically based on an average of the preceding 24 months of month-end working capital. This timeframe smooths out seasonal spikes and provides a stable, defensible figure.
How do you handle seasonal inventory in the peg?
You should apply a monthly seasonal adjustment to the average to reflect the specific time of year the deal closes. This prevents the buyer from paying for excess inventory that is only needed for a temporary, peak demand cycle.
What happens if the inventory is worth less than the peg expectation?
If the closing balance sheet shows inventory below the agreed peg, the difference results in a reduction of the final purchase price paid to the seller. This adjustment ensures the buyer is not penalized for receiving fewer operational resources than expected.
Why is the 90-day post-closing window important?
The post-closing window allows both parties to finalize the closing balance sheet with accurate, reconciled data. This period ensures all accounts receivable and payable are correctly reflected before the final peg adjustment is calculated.
