How to Use This SDE Valuation Calculator
- Enter revenue and earnings. Input your annual revenue and SDE (Seller's Discretionary Earnings). SDE = net profit + owner salary + benefits + personal or non-recurring expenses run through the business.
- Add SaaS metrics. Enter your monthly churn rate, year-over-year growth rate, and net revenue retention. These SaaS-specific metrics are major drivers of the SDE multiple.
- Set business characteristics. Configure owner dependency, customer concentration, and other factors that adjust the valuation up or down from the base multiple.
- Review your estimate. The calculator shows your SDE multiple, valuation range, and which factors are helping or hurting. Compare against market data for similar transactions.
What Is SDE and How It's Calculated for SaaS
Seller's Discretionary Earnings (SDE) represents the total financial benefit a single owner-operator derives from the business. It captures the true earning power available to a new owner who will replace the current operator. For SaaS businesses, SDE is calculated as:
- Net income from the P&L
- + Owner's salary and benefits (the largest add-back for most founder-led SaaS)
- + Personal expenses run through the business (travel, meals, home office, phone, etc.)
- + One-time or non-recurring costs (legal fees for a specific matter, one-time development projects, conference sponsorships)
- + Interest, depreciation, and amortization
For a typical founder-led SaaS with $500K in revenue, SDE might be $250-350K once the owner's $120K salary and $30-50K in discretionary expenses are added back. This SDE figure is then multiplied by the applicable SDE multiple to estimate valuation.
SDE vs. EBITDA: When to Use Which
The key difference: SDE includes the owner's compensation in earnings, EBITDA does not. This distinction determines the type of buyer the valuation is calibrated for.
| Factor | SDE | EBITDA |
|---|---|---|
| Owner comp included? | Yes | No |
| Typical buyer | Individual, search fund | PE firm, strategic acquirer |
| Business size | Under $3-5M ARR | $3M+ ARR |
| Team structure | Owner-dependent | Professional management |
| Typical multiples | 3-5x | 5-10x+ |
If a solo founder runs a $1.5M ARR SaaS and pays themselves $150K, EBITDA might be $200K while SDE is $350K. An SDE buyer pays 4x $350K = $1.4M. An EBITDA buyer pays 7x $200K = $1.4M. The purchase price can be similar, but the buyer profiles and deal structures are different.
How to Reduce Owner Dependency Before Selling
Owner dependency is the most actionable valuation lever for founder-led SaaS. Reducing it before going to market can increase your SDE multiple by 0.5-1.5x. Here are the highest-impact changes:
- Hire or contract customer support. If you handle support tickets personally, this is the first function to delegate. Buyers see founder-as-support as a red flag.
- Document all processes. Standard operating procedures for deployment, customer onboarding, billing, and content creation reduce transition risk.
- Build a development pipeline. Even a part-time developer who can handle bug fixes and minor features demonstrates the product isn't solely dependent on the founder's technical skills.
- Automate recurring tasks. Billing, reporting, onboarding emails, and infrastructure management should all run without manual intervention.
- Track your hours. Buyers will ask how many hours per week you spend. Getting below 15-20 hours of primarily strategic work significantly increases your multiple.
Start this process 6-12 months before going to market. It takes time to hire, train, and demonstrate that the business runs without you.
SaaS SDE Valuation FAQ
What is SDE (Seller's Discretionary Earnings)? +
SDE is the total financial benefit a single owner-operator derives from the business. It equals net profit plus owner salary and benefits, plus personal or non-recurring expenses run through the business. SDE represents the cash flow available to a new owner who will replace the current operator.
What is the difference between SDE and EBITDA for SaaS? +
SDE includes the owner's salary and benefits; EBITDA does not. Use SDE when the business has a single owner-operator whose role would be absorbed by the buyer. Use EBITDA when there's a professional management team that stays post-acquisition. Under $3-5M ARR with a solo founder, SDE is typically appropriate.
What SDE multiple do SaaS businesses sell for? +
Owner-operated SaaS businesses typically sell for 3-5x SDE, with exceptional businesses commanding 5-7x. Key drivers are monthly churn, growth rate, and owner dependency. Low churn (under 2% monthly), moderate growth (15%+), and low owner dependency achieve the upper range. High churn, flat growth, or heavy owner involvement typically trade at 2.5-3.5x.
How does owner dependency affect SaaS valuation? +
Owner dependency is one of the largest valuation discounts for founder-led SaaS. If the owner handles development, support, and sales, the buyer faces significant transition risk. Businesses where the owner works 10-15 hours per week on strategic tasks command higher multiples than those requiring 40+ hours of hands-on work. Reducing dependency before selling is one of the most effective ways to increase your multiple.
What churn rate is acceptable for selling a SaaS business? +
Monthly revenue churn below 3% is acceptable for owner-operated SaaS, and below 2% is considered strong. Annual gross churn below 10% is the gold standard. Churn above 5% monthly significantly compresses SDE multiples because it constrains growth and makes revenue less predictable. Reducing churn before listing is one of the highest-ROI pre-sale activities.
When should I use SDE vs. ARR multiple for my SaaS? +
Use SDE multiples when the business is founder-led with under $2-3M ARR and the owner's role is significant. Use ARR multiples when the business has $2M+ ARR and a professional team, with buyers pricing on revenue quality rather than owner cash flow. In the $1-3M ARR range, either methodology can apply — try both calculators to understand the range.
