SDE vs EBITDA for E-commerce (Plain-English Guide)

SDE (Seller's Discretionary Earnings) is for owner-operated businesses. EBITDA is for businesses with a management team. Those two sentences are the whole framework.

The rule of thumb: if you are the primary operator and draw a salary or distributions, use SDE. If a management team runs the business without you, use EBITDA. Most e-commerce businesses under roughly $1M in annual earnings use SDE. Above that level, with real management infrastructure, EBITDA is the standard.

Use the wrong one and you misstate the business by 20-40%. On a $500K-earning business, that gap is $400K-$600K in purchase price. It is not a rounding error.

SDE: What It Is and What Goes Into It

SDE measures the total economic benefit a single working owner gets from the business. Start with net profit, then add back everything the owner runs through the business for personal benefit, plus non-cash items.

SDE = Net Profit + Owner Salary + Owner Benefits + One-Time Costs + Depreciation + Amortization + Interest

Legitimate add-backs for an e-commerce business:

• Owner's salary and payroll taxes
• Health insurance premiums paid through the business
• Personal vehicle or travel expensed to the business
• One-time legal, consulting, or software costs that will not repeat
• Depreciation, amortization, and interest on business debt

The logic: a buyer stepping in captures the owner's salary because they are replacing the owner. That salary is not a cost to the new operator. It is earnings. So it goes back into the earnings base.

The limit: this only works if one person can run the business. Once the business needs a management team, those salaries are real ongoing costs. They do not come back out.

EBITDA: What It Is and When It Applies

EBITDA shows core operating profitability by stripping out financing and accounting decisions. It does not add back the owner's salary, because a business with management infrastructure pays a manager regardless of who owns it.

EBITDA = Net Profit + Interest + Taxes + Depreciation + Amortization

No owner salary. No personal benefits. Use EBITDA when:

• A management team runs day-to-day operations
• The owner could step away and the business keeps running
• Annual earnings are above roughly $1M and hiring a replacement manager is realistic
• The buyer is institutional or strategic, not an individual stepping in as operator

On a business where the owner takes no salary and a full team is in place, EBITDA and SDE will be nearly identical. The gap only appears when the owner's compensation is significant.

SDE vs EBITDA: Side-by-Side

| | SDE | EBITDA | |---|---|---| | Adds back owner salary? | Yes | No | | Adds back owner benefits? | Yes | No | | Adds back D&A and interest? | Yes | Yes | | Best for | Owner-operated, under ~$1M earnings | Managed businesses, above ~$1M earnings | | Typical buyer | Individual operator, small PE | Institutional, strategic, larger PE | | 2026 e-commerce multiple range | 2-4.5x | 3.5-5x |

A Worked Example: Same Business, Two Numbers

An outdoor gear brand on Amazon, founder-operated. Annual P&L:

• Revenue: $2,000,000
• COGS: $700,000
• Amazon FBA and platform fees: $340,000
• PPC spend: $200,000
• Owner salary: $150,000
• Contractors (VA, designer): $60,000
• Software: $20,000
• Owner health insurance (run through business): $12,000
• One-time trademark legal cost: $18,000
• Depreciation on equipment: $10,000
• Interest on credit line: $8,000
• Net Profit: $482,000

EBITDA: $482,000 + $8,000 interest + $10,000 D&A = $500,000

SDE: $482,000 + $150,000 salary + $12,000 health insurance + $18,000 one-time legal + $10,000 D&A + $8,000 interest = $680,000

Same business. $500K vs $680K. A $180,000 difference in the earnings base before any multiple is applied.

The valuation gap at 3x:

| Metric | Earnings Base | 3x Multiple | Valuation | |---|---|---|---| | EBITDA | $500,000 | 3x | $1,500,000 | | SDE | $680,000 | 3x | $2,040,000 |

The $540,000 gap is real. The correct metric here is SDE. This founder is the operator. A buyer stepping in captures that $150K salary. Using EBITDA hands the buyer a $540K argument to lower the price. Using SDE on a managed business creates friction in diligence when buyers challenge the add-backs.

Get the metric right before any buyer conversation starts.

What Multiples Apply to Each in 2026?

Consistent with what buyers are paying across 50+ deals reviewed:

| Business Type | Multiple Range | Right Metric | |---|---|---| | Single-channel Amazon FBA | 2-3x | SDE | | Amazon + DTC | 3-4x | SDE or EBITDA | | Amazon + TikTok Shop | 3.5-4.5x | SDE or EBITDA | | Multi-channel (3+ channels, managed) | 3.5-5x | EBITDA |

The aggregator era pushed multiples to 5-6x. Those funds are mostly restructured or shut down. Current buyers are operators and strategic acquirers who understand unit economics.

For businesses at the crossover point (earnings around $1M, partial management in place), most buyers want to see both metrics, normalize for partial management costs, and apply a multiple that reflects the actual level of owner dependency. Full detail on what moves you up or down inside these ranges is in how to value an e-commerce business in 2026.

How to Know Which Metric a Broker Is Using

Listings often present the metric that makes the deal look best. A listing at "3x EBITDA" for an owner-operated business is almost certainly understating the price in SDE terms. A listing at "2.5x SDE" for a managed business may be inflating it.

Three questions to ask before any call:

Is the owner's salary included or excluded? Ask for the add-back schedule. Every well-prepared seller has one. It lists every item added back with dollar amount and justification.

What would a replacement manager cost? If the answer is $80K-$150K and that salary is not in the current expenses, the business may need EBITDA, not SDE. Or the multiple needs to reflect that the buyer is stepping into an operator role.

Are the multiple and the metric consistent? SDE multiples and EBITDA multiples for the same business type are not interchangeable. Single-channel FBA at 3x SDE is reasonable. That same business at 3x EBITDA (with owner salary excluded) means the seller expects more than the multiple implies. Confirm both numbers before any LOI conversation.

The full due diligence process, including financial verification and add-back scrutiny, is in how to acquire an e-commerce business in 2026. The buyer's perspective on what those numbers signal is in what I look for when acquiring an e-commerce business.

The Short Version

SDE is for owner-operators. EBITDA is for managed businesses. The crossover is roughly $1M in annual earnings and the presence of a real management team. The metric determines the earnings base. The earnings base times the multiple determines the price. Get the metric wrong and every number that follows is wrong too.
