Where You Stand Against the Market
NRR benchmarks across B2B SaaS have never been more clearly defined. Top-quartile companies exceed 120%. The median sits at 106%. Anything below 100% means your existing base is shrinking — and every new logo you close is partially just filling that hole.

Year 1 Growth Rate by NRR Scenario
Same starting ARR. Same ambition. Retention is the variable that separates the two trajectories from month one. At 90% NRR, 10% of your base leaves every year — that revenue must be replaced before you grow a single dollar.
02 · Year 1
The Cost of Replacing Churned Revenue
Below 100% NRR, revenue leaks out the bottom and your sales team refills the bucket before the business grows a dollar. New-logo ARR is the most expensive kind to buy: the median B2B SaaS company spends $2.00 in sales and marketing to win $1 of new ARR, versus $1.00 for a dollar of expansion. Churn forces you to re-buy revenue you already had, at the premium price.

Churn locks you into the expensive path. You spend 2.0× to win back revenue you already had — a bill you pay again every year it keeps leaking.

extra S&M / year vs. expansion
The median B2B SaaS company spends $2.00 in sales and marketing to acquire $1 of new ARR, versus $1.00 per $1 of expansion. A dollar retained and expanded is roughly twice as capital-efficient as a dollar won from a new logo. Source: Benchmarkit 2025 SaaS Performance Metrics (2024 data), with Pavilion.
What Your Sales Team Actually Has to Close
Your growth target is fixed. What changes with NRR is how much of it your existing base covers — and how much lands on your sales team's quota. Churn inflates that number. Expansion shrinks it. The difference is real pipeline.

Revenue Trajectory Over 9 Years
Compounding works both ways. The NRR gap doesn't grow linearly — it accelerates. The area between these two lines is the cost of inaction.
05 · Trajectory
Revenue gap (your opportunity)
Revenue goal (at 100% retention)
The default scenario models a venture-scale path: $2M ARR just after product-market fit growing to a $100M ARR exit over 9 years — the start and end points of Battery Ventures' T2D3 framework ("triple, triple, double, double, double"), and roughly the median founding-to-IPO timeline. Median ARR at IPO actually runs higher (~$220M), so $100M is a conservative exit anchor. Change any input for your own numbers. Sources: Battery Ventures (T2D3); Meritech (SaaS IPOs).
Estimated Exit Valuation
Private SaaS is valued on a multiple of ARR, and that multiple is driven by market conditions, growth rate, and net revenue retention. Retention wins twice: it compounds into a larger ARR base and earns a higher multiple on top. Software Equity Group's index shows companies below 100% NRR trade at 3.1× revenue, while those above 120% trade at 9.3×.

Growth is the exit-year rate; SCI is the SaaS Capital Index (public median ARR multiple, 3.8× as of Jul 2026, adjustable in Advanced Inputs). The baseline is the center of a ±30% range.

The Real Reason
Most companies will see these numbers and still do nothing.
Building this model, one thing kept surfacing: retention is the highest-leverage number on the page. Move net revenue retention a few points and the growth rate, the sales burden, and the exit valuation all move with it. The lever is already inside the base you have, which is exactly why the numbers get big. This is a real opportunity, not a rounding error.
So why does it sit unclaimed? Because before the sale, progression is designed, and after the sale, we mostly hope for it. Sales gets a pipeline, a forecast, and a room full of people paid to advance it. Post-sale gets a health score and a QBR. The cost of churn never shows up as a line item, so you feel it as "we need more pipeline" and hire more sellers to refill a bucket that is quietly draining. And renewal gets treated as an event at the end instead of a pipeline from day one. If you have to build the case for renewal in the last quarter, you waited too long.
Post-sale is not churn insurance. It is a revenue engine. This calculator is the arithmetic. The operating system that captures it is the book.
