NRR (Net Revenue Retention)
What is NRR (Net Revenue Retention)?
NRR (Net Revenue Retention), also known as Net Dollar Retention (NDR), is a critical SaaS metric that measures the percentage of recurring revenue retained from existing customers over a specific period, accounting for expansions, contractions, and churn. NRR is expressed as a percentage and serves as a key indicator for revenue forecasting, business health assessment, and investor valuation in subscription-based business models.
Unlike gross retention metrics that only track revenue loss, NRR captures the complete picture of customer revenue dynamics within a cohort. An NRR of 115% means that even without acquiring a single new customer, your revenue from existing customers grew by 15% through upsells, cross-sells, seat expansions, and usage-based growth. This metric has become the gold standard for evaluating SaaS companies because it reflects both retention effectiveness and expansion capacity within the existing customer base.
NRR is particularly crucial for pipeline and forecasting teams because it provides a predictable revenue foundation independent of new customer acquisition. RevOps and finance teams use NRR to build bottom-up revenue forecasts, model growth scenarios, and assess the sustainability of revenue targets. Investors scrutinize NRR alongside ARR growth because companies with NRR above 120% demonstrate product-market fit, efficient growth, and reduced dependency on expensive new customer acquisition to hit revenue goals.
Key Takeaways
Forecasting Foundation: NRR enables accurate revenue forecasting by quantifying how much growth comes from existing customers versus new acquisition
Expansion Economics: NRR above 100% indicates your product naturally expands within accounts, creating capital-efficient growth without high acquisition costs
Valuation Driver: Public SaaS companies with NRR above 120% typically command premium valuations due to predictable, sustainable growth profiles
Cohort Performance: Tracking NRR by customer cohort, segment, or acquisition channel reveals which customers drive long-term value
Pipeline Independence: Strong NRR reduces pressure on sales pipeline generation, as existing customers fund significant growth
How It Works
NRR measures the net revenue change within a defined customer cohort over a specific period, typically calculated monthly or annually. The calculation begins with the total recurring revenue from existing customers at the start of the period, then adds expansion revenue (upgrades, additional seats, cross-sells, usage increases) and subtracts contraction revenue (downgrades, seat reductions) and churned revenue (cancellations).
The metric isolates revenue movements within the existing customer base while excluding all new customer bookings. This provides pipeline and forecasting teams with a pure view of organic revenue growth or contraction from current accounts. For example, if Q1 begins with $5M in ARR from existing customers, adds $800K in expansion, loses $200K to downgrades, and $300K to churn, the ending ARR is $5.3M, producing an NRR of 106% ($5.3M / $5M).
Revenue operations teams layer NRR into multi-year forecasting models by applying cohort-specific NRR rates to project future revenue. A company with $50M ARR and consistent 120% NRR can forecast $60M from existing customers alone in year two, establishing a revenue floor that de-risks growth targets. Finance teams combine NRR projections with new customer acquisition forecasts to build comprehensive revenue models for board presentations and investor reporting.
Advanced forecasting teams segment NRR by customer characteristics—enterprise vs. mid-market, product tier, acquisition channel, industry vertical—to identify high-performing cohorts and optimize go-to-market investments. For instance, discovering that customers acquired through product-led growth channels show 130% NRR while enterprise sales customers show 110% NRR might shift resource allocation toward self-serve expansion programs.

Use Cases
Multi-Year Revenue Forecasting
Finance and RevOps teams use NRR as the cornerstone of bottom-up revenue models. A company with $100M ARR and 115% NRR can forecast $115M from existing customers next year, $132M in year two, and $152M in year three from the current customer base alone. This provides a conservative growth foundation, with new customer acquisition representing upside rather than required growth to hit targets.
Investor Reporting and Valuation
CFOs and investor relations teams highlight NRR in board decks, earnings calls, and investor presentations because it demonstrates sustainable growth potential. A company showing consistent 125% NRR over multiple quarters signals to investors that the business has strong unit economics, product-market fit, and efficient growth mechanics that justify premium valuations compared to companies with lower NRR.
Sales Capacity Planning
Sales operations teams use NRR forecasts to determine how many new customer acquisition reps to hire versus account expansion specialists. If NRR analysis shows that 30% of revenue growth comes from existing customers organically, the company can allocate more sales capacity to expansion motions rather than new logo hunting, improving overall CAC efficiency and shortening payback periods.
Implementation Example
NRR-Based Revenue Forecasting Model
Most finance and RevOps teams build NRR forecasting models in spreadsheets or financial planning tools, integrating data from CRM and billing systems.

Scenario Planning Framework:
According to McKinsey's research on SaaS growth, NRR serves as a critical input for scenario planning and risk assessment. Forecasting teams should model:
Conservative Case: Apply worst historical NRR (e.g., 105%) to existing ARR
Base Case: Use trailing 12-month average NRR (e.g., 115%)
Upside Case: Project improved NRR based on product releases or CS program initiatives (e.g., 125%)
Revenue forecasting best practices from SaaS Capital's benchmarking data recommend monthly NRR monitoring for operational course-correction and annual NRR reporting for strategic planning. Companies should track NRR volatility—large month-to-month swings indicate forecasting risk—and investigate outliers promptly.
Finance teams typically integrate NRR models with pipeline forecasting, combining bottom-up existing customer projections with top-down new customer acquisition targets to create comprehensive revenue forecasts with confidence intervals.

Frequently Asked Questions
What is NRR (Net Revenue Retention)?
Quick Answer: NRR measures the percentage of revenue retained from existing customers over time, including expansions, contractions, and churn. NRR above 100% means your customer base generates revenue growth without new acquisition.
Net Revenue Retention provides forecasting teams with a critical metric for projecting sustainable growth. It answers: "If we stopped acquiring new customers today, how would our revenue change?" This makes NRR essential for building bottom-up revenue forecasts and assessing business health. Unlike metrics that focus solely on losses, NRR captures the full revenue dynamics within your customer base, making it the most comprehensive retention and expansion metric for SaaS businesses.
What's the difference between NRR and NDR?
Quick Answer: NRR (Net Revenue Retention) and NDR (Net Dollar Retention) are identical metrics with different names. Both measure revenue retention including expansion from existing customers. The terms are used interchangeably in the industry.
Some companies and investors prefer "Net Revenue Retention" while others use "Net Dollar Retention," but the calculation methodology and business interpretation are exactly the same. The key distinction is with GRR (Gross Revenue Retention), which excludes expansion revenue and caps at 100%, whereas NRR/NDR includes expansion and can exceed 100%. When reading investor presentations or industry reports, treat NRR and NDR as synonymous terms.
How do you calculate NRR?
Quick Answer: NRR = (Starting ARR + Expansion - Contraction - Churn) / Starting ARR × 100. For example, starting with $10M ARR, adding $2M expansion, losing $500K to downgrades and $1M to churn gives $10.5M ending ARR, or 105% NRR.
The calculation requires clean categorization of revenue movements within an existing customer cohort. Starting ARR includes all recurring revenue from customers present at period start. Expansion includes upgrades, additional seats, cross-sells, and usage-based increases. Contraction includes downgrades and seat reductions. Churn includes full cancellations. New customer revenue is excluded entirely. Most companies calculate monthly NRR for operational tracking and annual NRR for strategic planning and investor communications.
Why is NRR important for forecasting?
NRR is critical for forecasting because it quantifies the revenue growth or contraction from existing customers, which typically represents 60-80% of total revenue for mature SaaS companies. Accurate NRR projections enable finance teams to build reliable multi-year revenue models with predictable growth floors. A company with $100M ARR and 120% NRR has a $120M revenue foundation next year before counting any new customers, dramatically reducing forecast risk.
This predictability makes NRR essential for resource planning, hiring decisions, and capital allocation. If NRR projections show strong organic growth from existing customers, companies can invest more aggressively in product development and customer success, knowing that revenue growth doesn't depend entirely on expensive new customer acquisition. Conversely, declining NRR signals that forecasts relying heavily on existing customer expansion may be at risk, requiring increased investment in new customer pipeline generation.
What is a good NRR for forecasting purposes?
For forecasting reliability, NRR above 100% is essential because it means existing customers generate growth rather than requiring new acquisition to offset churn. Best-in-class SaaS companies target NRR above 120% for confident growth forecasting. NRR between 100-110% requires strong new customer acquisition to hit growth targets, increasing forecast risk. NRR below 100% signals that churn exceeds expansion, meaning the business must acquire new customers just to maintain current revenue levels.
From a forecasting perspective, NRR stability matters as much as the absolute number. Consistent 110% NRR over eight quarters enables more reliable projections than volatile NRR swinging between 105-125%. Revenue operations teams should track NRR standard deviation and investigate root causes of variability—seasonality, large customer concentration, or operational issues—to improve forecast confidence intervals and reduce surprises.
Conclusion
Net Revenue Retention has emerged as the most critical metric for revenue forecasting, business health assessment, and investor valuation in B2B SaaS. For pipeline and forecasting teams, NRR provides the foundational data needed to build reliable multi-year revenue models, assess growth sustainability, and reduce dependency on unpredictable new customer acquisition.
Finance teams rely on NRR to create bottom-up revenue forecasts, model growth scenarios, and set realistic targets that balance existing customer growth with new customer acquisition. Sales operations teams use NRR insights to allocate capacity between new logo hunting and account expansion, optimizing CAC efficiency and payback periods. Customer success teams drive initiatives to improve NRR through expansion programs, churn prevention, and value realization strategies. Revenue operations teams integrate NRR tracking with forecast accuracy monitoring to continuously improve projection quality.
As SaaS business models mature and efficient growth becomes paramount, NRR will continue to serve as the definitive measure of customer revenue dynamics and growth predictability. Companies that consistently maintain NRR above 120% demonstrate strong unit economics, product value, and sustainable growth potential that justifies premium valuations and enables aggressive investment in future growth initiatives. For any subscription business, mastering NRR measurement, forecasting, and optimization is essential for building predictable, scalable revenue growth.
