Net Revenue Retention Waterfall Charts: The Complete SaaS Guide

Net revenue retention is the metric investors care most about — it tells you whether your existing customers are growing or shrinking over time. A waterfall chart is the best way to show why your NRR is what it is.

What is net revenue retention?

Net revenue retention (NRR), also called net dollar retention (NDR), measures how much revenue you retain from an existing customer cohort over a given period, including expansion and contraction. An NRR of 118% means that for every $100 of revenue you started with from existing customers, you ended the period with $118 — even before counting new logos.

NRR above 100% means your existing customer base is growing without any new sales effort. It's the clearest signal of product-market fit and pricing power. Top-quartile SaaS companies maintain NRR above 120%; enterprise-focused companies with strong expansion motions can exceed 130%.

Why use a waterfall chart for NRR?

A single NRR number — say, 118% — is useful but opaque. It doesn't tell you whether expansion is strong and churn is strong (a volatile business), or whether expansion is moderate and churn is low (a sticky business). These are very different situations with very different implications.

A waterfall chart decomposes NRR into its individual components — upsell, cross-sell, price increases, downgrades, and churn — so the audience can see the full picture at a glance. Starting from a 100% baseline, each positive bar shows a source of expansion, each negative bar shows a source of contraction, and the ending bar shows the resulting NRR.

This is especially powerful for board meetings and investor presentations, where the question is never just "what is NRR?" but "what's driving NRR, and is it sustainable?"

The anatomy of an NRR waterfall

A well-constructed NRR waterfall typically includes these bars:

Starting bar: Beginning cohort (100%)

This represents the revenue from a defined customer cohort at the start of the period. It's always 100% — this is the baseline against which everything else is measured. Some companies use dollar values instead of percentages, but percentage-based NRR waterfalls are more common because they're comparable across time periods and company sizes.

Positive bars: Expansion drivers

Break expansion into its meaningful components. The most common breakdown:

  • Upsell — customers moving to higher-tier plans or adding more seats
  • Cross-sell — customers purchasing additional products
  • Price increases — contractual or renewal-based price adjustments
  • Usage growth — for usage-based models, organic consumption increases

Separating these matters because they have different sustainability profiles. Upsell driven by genuine product adoption is more durable than price increases, which face a natural ceiling.

Negative bars: Contraction and churn

  • Downgrades — customers moving to lower-tier plans or reducing seats
  • Churn — customers who cancelled entirely

Some companies combine these into "gross revenue churn," but separating them is more informative. Downgrades suggest the customer is still engaged but cost-conscious; churn suggests a deeper product or fit issue.

Ending bar: Net revenue retention

The total on the right. If this is above 100%, you have net expansion. If below, you have net contraction. The height of this bar relative to the starting bar is the visual punchline of the entire chart.

Design best practices for NRR waterfalls

1. Use percentage, not dollars

NRR is inherently a percentage metric. Presenting it in percentage terms makes it comparable across quarters and across companies. The subtitle should clarify the cohort definition and time period: "Net revenue retention walk, Q1 2025 cohort, trailing 12 months."

2. Highlight the 100% line

Since 100% is the critical threshold, consider adding a subtle horizontal reference line or annotation at the 100% mark. This makes it instantly visible whether the company is in net expansion or net contraction territory.

3. Order by magnitude within direction

Put the largest positive driver first, then descending. Same for negatives. This puts the most important story elements in the most visually prominent positions.

4. Add trend context

A single quarter's NRR waterfall is useful; showing how the components have changed over time is even better. Consider placing the waterfall next to a small table showing the same breakdown for the prior 2-3 quarters, so the audience can spot whether expansion is accelerating or churn is creeping up.

5. State the insight in the title

"NRR held at 118% as expansion offset a 2pp increase in churn" is infinitely more useful than "Net Revenue Retention, Q1 2025." The title should answer the "so what?" question before the audience even looks at the bars.

NRR waterfall vs. ARR bridge: when to use which

These two charts are complementary, not interchangeable:

  • The ARR bridge shows the absolute dollar movement of your total ARR, including new business. It answers: "How did our total recurring revenue change?"
  • The NRR waterfall isolates existing customers and shows retention dynamics in percentage terms. It answers: "How healthy is our installed base?"

Most board decks include both: the ARR bridge for the full revenue picture, and the NRR waterfall for a deeper look at customer health. They naturally appear on consecutive slides.

Benchmarks to keep in mind

When presenting an NRR waterfall, it helps to know where you stand relative to peers:

  • Best-in-class (NRR > 130%): Snowflake, Datadog, and other usage-based or platform companies with strong expansion loops.
  • Very good (NRR 115-130%): Most successful enterprise SaaS companies with effective upsell motions.
  • Healthy (NRR 100-115%): SMB-focused SaaS or early-stage companies still building expansion playbooks.
  • Concerning (NRR < 100%): The installed base is shrinking. Requires urgent attention to churn and pricing.
