For SaaS CFOs and revenue leaders needing clear visibility into ARR movement and retention metrics
Visualize ARR movement from starting balance through new bookings, expansion, churn, and contraction to ending ARR. Calculate net revenue retention (NRR) and gross revenue retention (GRR) metrics, understand where revenue growth comes from, and model comprehensive ARR bridges for board reporting.
Ending ARR
$6.50M
ARR Growth
$1.50M
Net Revenue Retention
100%
Your ARR grew from $5,000,000 to $6,500,000 (30% growth). Your net revenue retention is 100%, indicating strong expansion from existing customers.
The ARR bridge visualization helps SaaS companies understand the key drivers of revenue growth by breaking down the components of ARR change. Net revenue retention (NRR) above 100% indicates that existing customers are expanding their usage faster than churn and contraction combined, a key indicator of product-market fit. Gross revenue retention (GRR) measures your ability to retain existing revenue without considering expansion, with best-in-class SaaS companies maintaining GRR above 90%.
Understanding the composition of ARR growth is critical for scaling efficiently. Companies with high NRR (above 120%) can grow primarily through existing customer expansion, reducing customer acquisition costs. The balance between new ARR and expansion ARR reveals whether growth is driven by new customer acquisition or upsells to existing customers, informing go-to-market strategy and resource allocation.

The ARR bridge reveals the true drivers of SaaS growth that headline ARR numbers mask. A company experiencing strong headline growth could have two completely different stories: healthy diversified growth with substantial new bookings, meaningful expansion, and manageable churn, or growth masked by severe retention problems with high new bookings compensating for significant churn and contraction. The bridge exposes which scenario you face, informing whether to invest in sales, customer success, product, or fix underlying retention issues.
Net Revenue Retention (NRR) and Gross Revenue Retention (GRR) are the most predictive SaaS metrics for valuation and sustainability. NRR = (Starting ARR + Expansion - Churn - Contraction) / Starting ARR. Strong NRR enables hypergrowth with minimal new logo pressure. Moderate NRR can support healthy growth. When NRR shows churn exceeding expansion, companies require heavy new bookings to grow. GRR measures pure retention: GRR = (Starting ARR - Churn - Contraction) / Starting ARR. Higher GRR indicates excellent retention, while lower GRR may be concerning.
The Quick Ratio (New + Expansion) / (Churn + Contraction) measures growth efficiency. A higher Quick Ratio indicates healthy growth where you gain substantially more than you lose. A moderate Quick Ratio is acceptable but growth requires more effort. A lower Quick Ratio means you are losing revenue faster than gaining it relative to scale, indicating fundamental business issues. Public SaaS companies at scale typically have strong Quick Ratios, while early-stage companies often see lower ratios as they find product-market fit.
Startup finding PMF with high churn but strong new bookings
Substantial ending ARR growth, moderate NRR and GRR, healthy Quick Ratio
Scaling company with improving retention and expansion
Significant ending ARR growth, strong NRR above baseline, excellent GRR, strong Quick Ratio
Established SaaS with strong expansion motion
Considerable ending ARR growth, strong NRR with expansion exceeding churn, very high GRR, excellent Quick Ratio
Public SaaS with best-in-class metrics
Exceptional ending ARR growth, outstanding NRR with strong expansion, near-perfect GRR, exceptional Quick Ratio
GRR (Gross Revenue Retention) measures pure retention: how much ARR you keep from existing customers excluding expansion. Lower GRR indicates revenue lost to churn and contraction. NRR (Net Revenue Retention) includes expansion: strong NRR means expansion exceeded churn. NRR can exceed 100%, GRR cannot. Both metrics together show the full retention story.
Best-in-class companies achieve strong NRR with expansion-driven growth. Good NRR shows expansion offsetting most churn. Acceptable NRR may show slight net contraction. Lower NRR can indicate significant retention challenges. Early-stage companies often see lower NRR while finding PMF, and should improve as they mature. Enterprise SaaS typically targets higher NRR levels.
Increase numerator (new + expansion): accelerate sales, improve expansion programs, add new products for cross-sell. Decrease denominator (churn + contraction): improve onboarding, customer success, product value. Most efficient gains come from reducing churn and increasing expansion since existing customers have zero CAC. Aim for a healthy Quick Ratio that demonstrates efficient growth.
Both, but expansion often has better economics. Expansion has zero CAC, shorter sales cycles than new logos, and higher win rates. Companies with strong NRR can achieve substantial growth from existing customers alone. That said, new bookings expand total addressable market and customer base for future expansion. A balanced approach typically includes meaningful contributions from both new customer acquisition and expansion.
Monthly for internal management (track trends, early warning signs). Quarterly for board reporting (aligns with business reviews). Annually for strategic planning and valuation analysis. Leading SaaS companies review ARR bridge in weekly revenue meetings to monitor metrics like NRR, churn, and Quick Ratio in real-time.
NRR can improve from: product stickiness (integrations, data lock-in), expansion programs (CS-led upsell, product-led growth), multi-product strategy (more to expand into), and moving upmarket (larger customers may expand more). NRR can decline from: economic downturns (budget cuts), competitive pressure, product quality issues, or pricing misalignment with value.
