Should You Switch to Usage-Based Billing? Calculate Your ROI First
Bas de GoeiSuccessful SaaS companies know that keeping customers happy matters just as much as finding new ones. That's where net revenue retention, or NRR, becomes one of your most important numbers to track.
NRR in SaaS means the percentage of recurring revenue you retain from existing customers over a period after expansions and minus downgrades and churn.
When NRR is above 100%, your existing base spends more than the revenue you lost, which signals strong product value and expansion potential. NRR shows whether expansion from current customers outweighs contraction and churn.
Note: Want a deeper dive into the concept and how it is used in board decks? Read our guide to net dollar retention.
Yes. Net dollar retention (NDR) and net revenue retention are two names for the same metric used widely in SaaS.
Gross revenue retention (GRR) only looks at revenue kept from the same customers and excludes expansion revenue. GRR can never exceed 100%. Track both to avoid masking churn with expansion.
Quick takeaway: Use NRR to see net growth from your base. Use GRR to see pure retention without the lift from upsells.
Note: For a side-by-side breakdown, seeNRR vs. GRR.
Net revenue retention formula (monthly view):
NRR (%) = [(Starting MRR + Expansion MRR − Contraction MRR − Churned MRR) ÷ Starting MRR] × 100
Start the month at $100,000 MRR. During the month, you add $15,000 in expansions, lose $5,000 to downgrades, and $2,000 to churn.
NRR = ($100,000 + 15,000 − 5,000 − 2,000) ÷ $100,000 = 1.08 → 108%
Result: You grew revenue from the same customers by 8% without adding new customers.

NRR above 100% is good because expansion offsets downgrades and churn. Many teams set the floor at 100% and push higher over time as the product matures and upsell paths improve.
Public and private benchmarks vary by segment, but the rule of thumb holds: the higher above 100%, the healthier the base.
SaaS retention rates context: GRR often sits lower than NRR because it excludes expansion. Track both to see where revenue durability comes from.

Here are some core reasons why NRR is so important in the SaaS industry:
You can calculate net revenue retention SaaS metrics with a simple workflow.
This flow avoids double counting and aligns teams. Finance uses it to build trend lines. Customer success uses it to target savings. Product uses it to spot where adoption drives upsell paths.
Tip: Pair NRR with GRR in SaaS dashboards. GRR shows pure retention. NRR shows net growth from the same base. Together, they give you a clean view of SaaS retention rates.
NRR is cross-functional:
NRR behaves differently depending on the monetization style. Plan moves and usage patterns change how expansion shows up. Let’s zoom in on each monetization strategy.
Expansion comes from more seats or higher tiers. Contraction comes from seat cuts or role changes. Watch adoption by team and the ratio of paid seats to total users. Strong admin adoption often predicts upgrades.
Expansion follows higher consumption. Contraction follows lower activity or better efficiency. Set clear billable metrics.
Align value with usage, then educate buyers on why more usage creates more outcomes. This is common in net revenue retention SaaS leaders with strong product adoption.
Expansion can come from both levers. Set upgrade prompts when either seats or usage hits a threshold. Make value steps clear so buyers understand the cost path before a renewal.
Expansion comes from add-on modules and higher editions at renewal. Build a calendar of value reviews 90 days before the renewal. Use product usage to tailor the offer.
Define what counts as net recurring revenue at your company. Document how credits, coupons, and service fees are treated. Publish the rules, so teams read the same number.
NRR meaning: Net revenue retention shows how much recurring revenue you kept and grew from the same customers over a period, including expansions and minus downgrades and churn.
The net revenue retention (NRR) formula is:
(Starting Recurring Revenue + Expansion − Contraction − Churn) ÷ Starting Recurring Revenue × 100.
Use MRR for monthly views or ARR for annual.
NRR is different from net recurring revenue because they represent separate parts of the formula. Some finance pages use “net recurring revenue” to describe the revenue from existing customers in the period, which is an input to the NRR calculation.
Net revenue retention is the percentage result after you add expansions and subtract contraction and churn.
A healthy NRR benchmark is 100% or higher. Above 100% means your base is expanding. Pair NRR with GRR to verify that expansion is not hiding a retention issue.
