Micro-SaaS businesses under $1M ARR typically sell for 2.5x to 4.5x SDE (Seller Discretionary Earnings), while those crossing $500K ARR with strong retention can command 3x to 5x revenue multiples. The method you use depends entirely on your revenue size and who is buying.
Most valuation advice assumes you are running a venture-backed SaaS with $10M ARR. That advice is useless for a solopreneur running a $200K ARR tool with 80% margins. Micro-SaaS valuation works differently because the buyer profile, deal structure, and risk profile are completely different.
SDE vs ARR: The Method That Matches Your Size
The wrong valuation method can leave six figures on the table.
Micro-SaaS valuation splits at roughly $500K ARR. Below that threshold, buyers use Seller Discretionary Earnings. Above it, ARR multiples take over. Use the wrong one and you either undervalue your business or scare off buyers with an unrealistic ask.
SDE calculates what a single owner-operator takes home: pre-tax profit plus owner salary and perks. It answers the question, “What does this business actually put in my pocket?” For a micro-SaaS doing $200K ARR with $120K profit and $60K owner salary, your SDE is $180K. At a 3x SDE multiple, that is a $540K valuation.
ARR multiples work for larger SaaS businesses where the buyer is not replacing an owner. They are paying for the recurring revenue stream and its growth trajectory. A micro-SaaS at $800K ARR growing 30% year over year might trade at 4x revenue, or $3.2M.
| ARR Range | Method | Typical Multiple | Buyer Type |
|---|---|---|---|
| Under $100K | SDE | 2.0x to 3.0x | Individual operators |
| $100K to $500K | SDE | 2.5x to 4.5x | Solo buyers, small firms |
| $500K to $1M | SDE or ARR | 3.0x SDE / 2.0x to 3.5x ARR | Small funds, searchers |
| $1M to $5M | ARR or EBITDA | 3.0x to 5.8x ARR | PE, strategic buyers |
The crossover between SDE and ARR is not clean. A buyer might use SDE for a $600K ARR business if the founder is critical to operations. Or they might use ARR if revenue is diversified and growing fast. The method follows the risk, not a formula.
Five Metrics That Move Your Multiple
The multiple is not fixed. It moves based on the quality and predictability of your revenue. Here are the five metrics that matter most.
1. Monthly churn rate. Buyers discount heavily for churn. A micro-SaaS with 3% monthly churn loses a third of its customers every year. At 1% monthly churn, you lose 11%. That difference can swing your multiple by a full point. We cover this in depth in our SaaS churn benchmarks for valuation guide.
2. Net revenue retention. If existing customers spend more over time, your business is worth more even without new logos. NRR above 110% signals a product that compounds value. Our post on net revenue retention and SaaS valuation breaks down how NRR above 120% can double your multiple.
3. Revenue concentration. One customer making up 30% or more of your ARR is a red flag. Buyers see concentration risk as existential. If that one customer leaves, your valuation collapses. We explain how to fix this in our guide on customer concentration risk in SaaS exits.
4. Owner dependency. Can the business run without you for 30 days? If every support ticket, sales call, and deployment goes through the founder, the buyer is acquiring a job, not a business. Reducing owner dependency before going to market can add 0.5x to 1.0x to your multiple.
5. Growth rate. A micro-SaaS growing 40% year over year will command a meaningfully higher multiple than one flat at the same ARR. Growth signals product-market fit and future earnings power. Buyers pay for trajectory, not history.
Flippa’s 2026 SaaS deal data shows smaller SaaS businesses sell in this profit multiple range. Revenue multiples range from 2.0x to 3.5x. Premium multiples up to 5.8x revenue go to businesses with verified competitive moats and strong retention metrics.
What Buyers Actually Look For in a Micro-SaaS
Buyers of micro-SaaS are not PE associates running DCF models. They are operators, search fund founders, and small holding companies. They evaluate three things fast.
Can I run this? The buyer wants to know if they can operate the product without the founder. Clean documentation, automated onboarding, and a support system that does not require the original author move the needle.
Is the revenue real? Buyers verify MRR by checking payment processor records, not dashboards. They look for seasonality, refund rates, and whether revenue comes from a handful of enterprise accounts or hundreds of self-serve customers. Diversified revenue is more valuable than concentrated revenue.
Will it decay? A micro-SaaS built on a platform API (Shopify app, Chrome extension) carries platform risk. A standalone product with direct customer relationships and low churn is worth more. Buyers discount for platform dependency because policy changes can kill the business overnight.
Buyers do not value your product. They value the predictability and transferability of your revenue. Every decision you make about documentation, automation, and customer diversification either builds or destroys that value.
Common Valuation Mistakes Micro-SaaS Founders Make
The biggest mistake is using ARR multiples from venture-backed SaaS comparables. A $300K ARR micro-SaaS is not worth 10x revenue because a public SaaS trades at 10x. The buyer pool, risk profile, and deal structure are completely different.
The second mistake is ignoring owner salary. If you are taking $80K in salary and your business shows $30K in profit, your SDE is $110K, not $30K. Buyers value SDE, not net income. Mixing up the two undervalues your business by 50% or more.
The third mistake is assuming growth will continue. A micro-SaaS that grew 60% last year might slow to 10% this year. Buyers price for sustainable growth, not peak growth. If your growth is decelerating, be upfront about it. Surprises during due diligence kill deals faster than bad numbers.

Frequently Asked Questions
How do you value a micro-SaaS with no revenue?
Pre-revenue micro-SaaS is valued using the Berkus method, which caps at $2M pre-revenue and $2.5M post-revenue across five risk factors. In practice, most micro-SaaS acquisitions require at least some MRR. Without revenue, you are selling potential, and buyers discount heavily for that risk.
What is a good SDE multiple for a micro-SaaS?
A SDE multiple of 3.0x to 4.5x is strong for a micro-SaaS under $500K ARR. Anything above 4.5x requires low churn, diversified revenue, minimal owner dependency, and growth above 25% year over year. Below 2.5x usually signals one or more risk factors the buyer is pricing in.
Can I use ARR multiples for a sub-$1M SaaS?
ARR multiples become relevant around $500K to $1M ARR, especially when the buyer is a fund or strategic acquirer rather than an individual operator. Below $500K, SDE is the standard because the buyer is effectively buying a job and valuing the total owner benefit.
How does customer concentration affect micro-SaaS valuation?
If one customer represents more than 20% of ARR, expect a 0.5x to 1.0x multiple reduction. At 30% concentration, many buyers will not proceed. Diversifying your customer base before going to market is one of the highest-ROI steps a founder can take.
What documentation increases my micro-SaaS valuation?
Buyers want a runbook covering product architecture, deployment steps, customer support workflows, and key vendor accounts. A well-documented business reduces transition risk and can add 0.25x to 0.5x to your multiple because the buyer can operate it without the founder.
