How to Value a Convenience Store: From SDE to Sale Price

In Part 1, we calculated SDE for Parkside Market across four years. Now we'll turn those earnings into a valuation—and show why using multiple metrics produces a more accurate estimate than relying on SDE alone.

Quick Recap: The Numbers

Parkside Market is a family-run convenience store with declining revenue but stable operations. Here's what we calculated:

Revenue declined 7% over four years. SDE shows inconsistency due to owner compensation choices, but the weighted average smooths this out.

Step 1: Calculate Weighted Averages

We weight recent years more heavily:

• Year 1 (most recent): 40%
• Year 2: 30%
• Year 3: 20%
• Year 4: 10%

Step 2: Apply Industry Multiples

Convenience stores have established industry multiples based on thousands of actual transactions:

• SDE Multiple: 2.34x (base)
• Revenue Multiple: 0.41x (base)

But these are just starting points. Every business has specific characteristics that adjust the multiple up or down.

Step 3: Risk Factor Assessment

Five factors adjust the base multiples:

Factor	Parkside Market	Adjustment
Owner Involvement	Moderate (buyer can run with some help)	1.00x (no adjustment)
Financial Trend	Declining (7% drop over 4 years)	0.93x (−7%)
Key Employees	None (entire family leaving)	0.90x (−10%)
Customer Concentration	Diversified (retail + lottery)	1.05x (+5%)
Books & Records	Adequate (organized but not CPA-prepared)	1.00x (no adjustment)

The declining revenue and lack of employees reduce value. The diversified customer base adds some back. Net result: buyers will pay 12% less than the base multiple.

Why These Adjustments Matter

Declining Revenue (−7%): Buyers worry the decline will continue. Even if the owners are just "coasting," buyers can't be certain. The trend creates uncertainty.

No Key Employees (−10%): The buyer inherits an empty store. They must hire, train, and hope those hires work out. This represents real cost and risk.

Diversified Customers (+5%): No single customer dominates. The mix of retail and lottery creates multiple revenue streams. If one weakens, the other cushions the impact.

Step 4: Calculate Adjusted Multiples

We apply the adjustment factor to both multiples:

Step 5: Dual-Metric Valuation

Using both SDE and revenue produces a more complete picture than either metric alone:

Notice the revenue valuation is higher. Why? Because revenue captures scale—the store processes $1.3M annually through the register. That represents established market presence, customer traffic, and supplier relationships that have value beyond pure profit.

Why Use Both Metrics?

SDE measures earnings power—what the owner takes home. Revenue measures market presence—the scale of operations. Both matter.

Consider: two stores both earning $207K in SDE. Store A does $1.3M in revenue (like Parkside). Store B does $500K in revenue. Same earnings, very different businesses. Store A has more customer transactions, more supplier leverage, more potential for margin improvement. Revenue captures this dimension.

Step 6: Weighted Combination (70% SDE / 30% Revenue)

SDE is the primary driver of small business value, but revenue provides a meaningful check:

This weighted approach prevents over-reliance on any single metric and produces a more holistic estimate.

Step 7: Add Inventory

Inventory transfers at cost—it's not part of business value but gets added to the purchase price:

The Final Valuation Range

No valuation is exact. Market conditions, buyer motivation, and negotiation all affect final price. A responsible estimate provides a range (±7%):

The business itself is worth approximately $410K-$475K. Add inventory and total purchase price runs $475K-$550K.

What This Means for a Buyer

At $512,780 purchase price, a buyer is paying:

• 2.47x annual SDE
• 0.38x annual revenue

They'll earn approximately $207K per year working in the business. The ROI depends on their ability to stabilize or reverse the revenue decline.

The declining trend creates both risk and opportunity. A capable operator might improve performance through:

• Enhanced product mix
• Better marketing and community engagement
• Improved inventory management
• Building the lottery customer base

But buyers will heavily scrutinize the decline during due diligence. They'll want to understand why revenue dropped and whether the trend can be reversed.

Compared to Peak Performance

In Year 3, Parkside did $1.4M in revenue. If that were still the current number, here's what changes:

• Weighted revenue: $1.38M (instead of $1.33M)
• Financial trend: Stable or growing (1.00x or 1.05x instead of 0.93x)
• Combined adjustment: 0.945x or 0.99x (instead of 0.879x)
• Final value: $525K-$565K (instead of $475K-$550K)

The declining trend costs approximately $40K-$50K in valuation—roughly 8-10%. That's the price of coasting.

Key Takeaways

Dual metrics matter. Using both SDE and revenue produces a more complete picture than either alone. The 70/30 weighting prioritizes earnings while incorporating scale.

Risk adjustments are significant. The 12% reduction from declining revenue and no key employees translates to real dollars. These aren't theoretical—they represent actual buyer concerns that affect offers.

Inventory is separate. The $442K business value reflects earnings power. Inventory adds to purchase price but isn't part of business valuation.

Trends drive value. The same SDE with an upward trend would command a premium. Declining trends create skepticism even if current earnings are acceptable.
