Expansion Revenue
Additional revenue generated from existing customers through upgrades, add-ons, or increased usage.
Definition
Expansion revenue represents the additional income generated when existing customers increase their spending with your business. This can occur through plan upgrades, purchasing additional features, buying more licenses, or increased usage-based billing. It's often more cost-effective than acquiring new customers.
Types of Expansion
Upselling
Upgrading to higher-tier plans with more features or capacity
Cross-selling
Adding complementary products or services
Usage Growth
Increased consumption in usage-based billing models
Seat Expansion
Adding more user licenses or team members
How to Calculate
Formula:
Expansion Revenue = Upsell Revenue + Cross-sell Revenue + Usage Growth Revenue
Expansion Rate:
(Expansion Revenue ÷ Starting Revenue) × 100
Real-World Example
SaaS Company:
- • Customer starts at $100/month (Basic plan)
- • Upgrades to $300/month (Pro plan) = $200 upsell
- • Adds integration feature for $50/month = $50 cross-sell
- • Doubles team size (+5 licenses at $20 each) = $100 expansion
Total Expansion Revenue: $350/month
