Expansion revenue is the additional recurring revenue you earn from existing customers through upgrades to higher tiers, add-ons, cross-sells, extra seats, extra usage and price increases. In MRR terms, expansion MRR is the sum of every month-on-month increase from customers who were already paying. It's tracked separately from new-customer revenue, and it's what pushes net revenue retention above 100%.
Key takeaways
- Expansion MRR = the total increase in MRR from customers who were already paying at the start of the period.
- Six sources: upgrades, add-ons, cross-sells, seats, usage and price rises.
- In ChartMogul's 2023 report, 37.1% of new ARR at $15M–$30M companies came from expansion.
- Only count the increase. A customer moving from $20 to $50 is $30 of expansion.
- Design the upgrade path on day one: if there's nothing to buy next, there's no expansion.
My local bakery has a clever habit.
It gives free samples of every bread it makes to local cafes, and tells them there's no minimum order. The cafes try the bread, love it, and order a small amount. Then, month by month, the orders grow as the bakery's bread becomes part of the menu.
I used that bakery in Chapter 7 of The Subscription Playbook as an example of land and expand. The "land" is the free sample. The "expand" is every extra loaf the cafe orders after that.
That second part has a name. It's expansion revenue, and it's the cheapest money you'll ever make.
What is expansion revenue?
Expansion revenue is the extra recurring revenue you earn from customers who are already paying you.
In Chapter 9 I defined it as "money you make selling more to your existing customers," like a move to a more expensive membership tier, plus money from cross-selling related products. In 2026 I'd add four more sources: extra seats, extra usage, add-ons and price rises.
What it isn't: revenue from new customers, one-off fees, or customers coming back after cancelling (that's reactivation).
Expansion MRR = Sum of MRR increases from customers who were paying at the start of the period
Expansion rate = Expansion MRR ÷ Starting MRR × 100
A third version tells you how much of your growth comes from the existing base:
Expansion share of new MRR = Expansion MRR ÷ (New-customer MRR + Expansion MRR) × 100
How do you calculate expansion MRR? A worked example
An online bookkeeping service, one month (illustrative)
Starting MRR is $30,000 from 100 clients.
- 4 clients move from the $250 plan to the $400 plan: 4 × $150 = $600
- 6 clients add a $90 payroll add-on: 6 × $90 = $540
- 2 clients add a second business entity at $200 each: $400
- New clients this month bring in $2,000 of MRR (not expansion)
Expansion MRR = $600 + $540 + $400 = $1,540
Expansion rate = $1,540 ÷ $30,000 = 5.1% for the month
Expansion share of new MRR = $1,540 ÷ ($2,000 + $1,540) = 43.5%
Nearly half of this firm's new monthly revenue came from clients it already had, with no marketing spend.

| Lever | How it works | Example from the research |
|---|---|---|
| Upgrade (upsell) | Customer moves to a higher tier | DocuSign's single-user plan up to Business Pro (book, Ch 7) |
| Cross-sell | Customer buys a related product | Zoom selling Phone and Contact Center to existing customers |
| Add-on module | Customer bolts on an extra capability | Employment Hero adding recruitment and engagement to payroll |
| Seats | More of the customer's team joins | Per-seat software as a team grows |
| Usage | Customer uses more of the value metric | Procore pricing on construction volume |
| Price rise | Same product, higher price | Xero's average revenue per customer rose 23% in FY26 |
The best businesses use more than one. Employment Hero lands with payroll, the service that's painful to move, then adds HR, recruitment and engagement tools. It passed A$300 million in ARR in October 2025, a tenfold increase in just over five years.
What does good look like?
There's less published data on expansion than on churn, but here's what's sourced.
| Source and year | Finding |
|---|---|
| ChartMogul, 2023 report | 37.1% of new ARR at $15M–$30M ARR companies came from expansion |
| ChartMogul, 2023 report | 39.2% of new ARR at companies with ARPA over $500 a month came from expansion |
| SaaS Capital, 2025 | Median NRR 101% and GRR 91%, which implies expansion of about 10% of starting revenue a year |
| Procore, FY2025 | NRR 106% and GRR 95%, which implies about 11 points of expansion |
| Zoom, FY2026 | Enterprise net dollar expansion of 98%: expansion didn't fully cover losses |
The pattern: the higher your price point, the more of your growth comes from expansion. Cheap, single-price products have little room to expand.
The gap between your net and gross retention is the simplest way to track your own expansion rate year to year.

Common mistakes
- Counting the full new price. A $250 client who moves to $400 is $150 of expansion, not $400.
- Mixing in new customers. A customer who signed up and upgraded in the same month is new MRR.
- Netting expansion against churn. Report expansion and churn separately, then combine them. Netting hides both stories.
- Giving everything away on the entry plan. In Chapter 7 I warned you to hold back. If the first tier has everything, there's nothing to expand into. See packaging: what goes in each tier.
- Pushing expansion on unhappy customers. Upselling someone who's struggling is a fast route to cancellation. Fix onboarding first.
How expansion revenue links to the book
Chapter 4 explained why usage-based pricing produces expansion automatically: as the customer grows, so does the bill.
Chapter 7, land and expand, is the strategy. Its five factors (an attractive initial offer, product/market fit, re-earning the business, solid onboarding and a funnel) are the conditions expansion needs.
Chapter 9 is the payoff. Combine expansion revenue with low churn and you get net negative churn.
How a gym, cafe or local service can use it
You don't need software to earn expansion revenue. You need a next step.
- Gym: off-peak, full and premium memberships, plus personal training packs and a family add-on.
- Cafe coffee club: a base coffee plan, a "coffee plus pastry" tier, and an office pack for workplaces.
- Cleaning or trades: price per room or per service, and offer a maintenance plan on top of the call-out.
Then track it. Each month, write down how much extra revenue came from existing members. If that number is zero three months running, your customers have nowhere to go.
What to do next
- Calculate last month's expansion MRR and expansion rate.
- List every way an existing customer can pay you more. Aim for at least two.
- Design your upgrade path with the pricing table builder.
- Check the result in your net revenue retention next quarter.
Frequently asked questions
Is expansion revenue the same as upsell revenue?
Upselling is one part of it. Expansion revenue covers every way an existing customer pays you more: moving to a higher tier (upsell), buying a related product (cross-sell), adding seats or usage, buying add-ons and absorbing a price rise. Most analytics tools lump these together as expansion MRR. Splitting them out shows you which lever is actually working.
Do price increases count as expansion revenue?
Yes, in most definitions, because the customer was already paying and now pays more. SaaS Capital's gross revenue retention explicitly excludes price increases, which tells you they sit on the expansion side of NRR. Report price-driven expansion separately, though. It's a different signal from customers choosing to buy more, and you can't repeat it every month.
What's a good expansion rate?
There's no single benchmark, but you can estimate one from retention data. SaaS Capital's 2025 medians for private B2B SaaS were 101% NRR and 91% GRR, which implies expansion of roughly 10% of starting revenue a year for a typical company. Procore's 2025 figures (106% NRR, 95% GRR) imply about 11 points. Track your own gap between NRR and GRR over time.
Should sales teams be paid commission on expansion?
Usually yes, but differently from new sales. In Chapter 4 I suggested rewarding salespeople on a customer's usage at the point of sale and on how that usage grows. If nobody is rewarded for expansion, nobody chases it. Many firms give account managers or customer success teams the expansion target, so the new-business team keeps landing customers.
How do I find expansion opportunities in my customer base?
Look for customers hitting limits: plan caps, seat counts, usage thresholds or frequent extra purchases. Those are buying signals. Monster.com in the book triggered a sales call when a customer ran low on job listings. Your billing system and product data can flag the same moments, so your offer arrives exactly when the customer needs more.
