Gross Revenue Retention (GRR)

GRR

Gross Revenue Retention (GRR) measures the percentage of beginning-period MRR retained from existing customers after accounting for cancellations and downgrades — but before adding any expansion revenue. It can never exceed 100% because it only measures retention, not growth. GRR is the purest signal of how well you hold onto the revenue you already have.

formula.sh

GRR = (Beginning MRR − Churned MRR − Contraction MRR) / Beginning MRR × 100

> Beginning MRR — total MRR from existing customers at period start
> Churned MRR — revenue fully lost from cancellations
> Contraction MRR — revenue reduction from customers who downgraded
> Expansion MRR is explicitly excluded — GRR is capped at 100%

example

example.sh

Beginning MRR $250,000. Lost $10,000 to cancellations. Lost $5,000 to downgrades.

($250,000 − $10,000 − $5,000) / $250,000 × 100

→ 94% GRR — the company retains 94 cents of every dollar of beginning MRR before counting any expansion.

why it matters

GRR reveals the floor of your retention health. Unlike NRR, which can be flattered by an aggressive upsell motion, GRR shows exactly how much revenue you retain without any help from expansion. A 94% GRR means you will always have at least 94% of your existing revenue at the start of next period — that is your floor.

For investors, GRR is a critical companion to NRR because it exposes hidden churn. A company with 115% NRR and 70% GRR is in a very different position than a company with 115% NRR and 95% GRR. The first company is dependent on constant upsell just to offset catastrophic churn. The second company has a stable base that expands naturally.

Benchmarks: enterprise SaaS targets 90%+ GRR annually, mid-market targets 85%+, SMB SaaS typically sees 70–85%. Below 70% GRR annually is a structural retention problem that no amount of expansion revenue will solve sustainably.

common mistakes

✗Presenting only NRR to investors without showing GRR — the difference between the two reveals the quality of your retention vs expansion mix.

✗Confusing annual GRR with monthly GRR — a 94% monthly GRR compounds to approximately 50% annual retention, which is catastrophic.

✗Not segmenting GRR by customer tier: enterprise GRR and SMB GRR require completely different remediation strategies.

pro tips

✓Use GRR as the baseline for your revenue forecast: multiply beginning ARR by GRR to get your contracted floor before any new sales or expansion.

✓When modeling fundraising scenarios, stress-test your GRR down 5–10 points to show investors your business survives a retention shock.

✓Track GRR improvement quarter-over-quarter as a lagging indicator of your customer success investment effectiveness.

the mrrsucks take

GRR is what you're left with when the expansion fairy goes home. If your GRR is below 80%, you don't have a retention strategy — you have a retention hope, and hope doesn't scale.

faq

Why can GRR never exceed 100%?+

Because GRR measures only revenue preserved, not revenue grown. It explicitly excludes expansion MRR. The best possible outcome is that every existing customer stays on the exact same plan — which equals 100% GRR.

Should I optimize for GRR or NRR?+

Both, but with different teams and tactics. GRR is optimized by improving product stickiness, onboarding, and support — the customer success function. NRR is optimized by adding expansion revenue on top of good GRR through pricing design and upsell motions.
