Summary

Comprehensive SaaS performance benchmarks covering acquisition, retention, efficiency, and unit economics metrics across SMB, mid-market, enterprise, and PLG segments. Median NRR compressed to 101% in 2025 while CAC payback improved to 20 months, reflecting a market shift toward efficiency over growth-at-all-costs. [src1]

Data vintage: Based on H2 2025 data from 1,500+ SaaS companies across all segments.

Key shift: Market-wide pivot to profitable growth — median EBITDA margins turned positive while NRR compression hit SMB and mid-market hardest.

Constraints

These benchmarks represent VC-backed SaaS companies with $1M-$100M ARR. Do not apply to bootstrapped, pre-revenue, or $100M+ public companies.
Figures are medians unless stated. Mean values are skewed by outliers; use median for planning, 75th percentile for ambitious targets.
Primarily US data (70% of sample). EMEA typically shows 10-15% lower CAC but 5-10% lower NRR.
Data collected H2 2025. If more than 6 months old, search for updated figures before citing.
Only compare companies within the same segment row. Cross-segment comparison is misleading.

Metrics

Acquisition Metrics

Customer Acquisition Cost (CAC)

Definition: Total sales and marketing spend divided by new customers acquired. Excludes customer success and onboarding costs.

Segment	Median	25th Pct	75th Pct	Top Decile
SMB (<$10K ACV)	$4,800	$2,500	$8,200	$1,800
Mid-Market ($10-100K)	$18,000	$12,000	$28,000	$8,500
Enterprise (>$100K)	$67,000	$42,000	$120,000	$32,000
PLG / Self-Serve	$1,200	$650	$2,800	$350

Trend: Up 14% YoY driven by rising paid channel costs.

Red flag threshold: CAC exceeding 12 months of contract value = unsustainable acquisition economics.

CAC Payback Period

Definition: Months to recover fully loaded CAC from gross margin of a new customer.

Segment	Median	Healthy Range	Alarm Threshold
SMB	11 months	6-14 months	>18 months
Mid-Market	17 months	12-22 months	>28 months
Enterprise	22 months	16-30 months	>36 months
PLG	6 months	3-9 months	>14 months

Retention Metrics

Net Revenue Retention (NRR)

Definition: (Starting MRR + expansion - contraction - churn) / starting MRR, measured over 12 months.

Segment	Median	25th Pct	75th Pct	Top Decile
SMB	95%	88%	103%	110%
Mid-Market	103%	96%	112%	125%
Enterprise	112%	104%	128%	145%
PLG	98%	90%	108%	118%

Trend: Down 3-5 points YoY. Median compressed to 101% overall.

Red flag threshold: Below 100% = revenue base contracting. Below 90% = urgent churn problem.

Gross Revenue Churn

Definition: MRR lost from downgrades and cancellations / starting MRR, annualized.

Segment	Median	25th Pct	75th Pct	Top Decile
SMB	12% annual	8%	18%	5%
Mid-Market	8% annual	5%	13%	3%
Enterprise	5% annual	3%	9%	1.5%
PLG	14% annual	9%	22%	6%

Efficiency Metrics

Rule of 40

Definition: Revenue growth rate (%) + EBITDA margin (%).

ARR Range	Median	25th Pct	75th Pct	Top Decile
$1-10M ARR	28%	12%	42%	55%
$10-50M ARR	35%	22%	48%	62%
$50M+ ARR	38%	28%	52%	68%

Unit Economics

LTV:CAC Ratio

Definition: Customer lifetime value / customer acquisition cost.

Segment	Median	25th Pct	75th Pct	Top Decile
SMB	2.8:1	1.8:1	4.2:1	6.0:1
Mid-Market	3.6:1	2.4:1	5.5:1	8.0:1
Enterprise	4.5:1	3.0:1	7.0:1	12.0:1
PLG	3.2:1	2.0:1	5.0:1	7.5:1

Gross Margin

Model	Median	25th Pct	75th Pct	Top Decile
Pure SaaS	78%	72%	84%	89%
SaaS + Services	65%	58%	72%	78%
Usage-Based	72%	65%	80%	86%

Composite Metrics & Rules of Thumb

Rule	Formula / Threshold	Interpretation
Rule of 40	Growth rate + EBITDA margin ≥ 40%	Healthy balance of growth and profitability
LTV:CAC > 3:1	LTV / CAC > 3.0	Sustainable unit economics — safe to scale
Magic Number > 0.75	Net new ARR / prior quarter S&M	Efficient growth engine — increase spend
CAC Payback < 18mo	CAC / (monthly rev × GM)	Healthy acquisition cash cycle
NRR > 110%	Expansion > contraction + churn	Best-in-class retention compounding growth
Burn Multiple < 2x	Net burn / net new ARR	Capital-efficient growth

Segment Definitions

Segment	Definition	Typical Characteristics
SMB SaaS	ACV < $10K, target < 100 employees	Self-serve or low-touch, monthly/annual contracts, high logo churn offset by volume
Mid-Market SaaS	ACV $10K-$100K, target 100-2,000 employees	Inside + field sales, annual contracts, 3-6 month sales cycles
Enterprise SaaS	ACV > $100K, target 2,000+ employees	Field sales, multi-year contracts, 6-18 month cycles, procurement
PLG SaaS	Self-serve acquisition, freemium or free trial	Bottom-up adoption, usage-based expansion, low CAC, higher free-tier churn

Common Misinterpretations

Comparing logo churn to revenue churn: They measure different things. A company can have 10% logo churn but negative net revenue churn if expansion from remaining customers exceeds losses.
Applying enterprise NRR targets to SMB: Enterprise NRR above 120% is normal due to seat expansion. Expecting this in SMB sets unrealistic targets.
Treating median as a target: Median means half of companies are below. Use 75th percentile for ambitious targets; median is a sanity check.
Ignoring gross margin in CAC payback: Raw payback without gross margin adjustment understates true payback by 20-30%.
