Growth in SaaS isn’t just about moving fast—it’s about moving smart. By focusing on the right revenue growth metrics, you get a clearer picture of your business performance and can make smarter decisions that lead to sustainable success.
In the SaaS world, growth isn’t just about acquiring more users—it’s about acquiring the right users, retaining them, and optimizing every stage of their journey to drive predictable and scalable revenue. Whether you’re a growing startup or an established SaaS provider, tracking the right revenue growth metrics is essential to measure success, make informed decisions, and stay competitive.
Let’s break down the key metrics every SaaS business should be monitoring regularly.
Monthly Recurring Revenue is the heartbeat of your SaaS business. It tells you how much predictable revenue you’re generating each month from active subscriptions.
Key insights MRR offers:
Overall growth trends
The impact of new customer acquisitions
Churn and downgrade signals
Expansion through upgrades and cross-sells
Pro Tip ⇨ Track MRR by source (new vs. existing customers) to better understand which segments are driving growth.
LTV shows the total revenue a business can expect from a single customer over the entire relationship.
LTV = Average Revenue per Account (ARPA) × Customer Lifetime
Pairing LTV with Customer Acquisition Cost (CAC) helps determine how sustainable your growth strategy is. The higher the LTV-to-CAC ratio, the more profitable your SaaS model is.
CAC measures how much you spend to acquire a single paying customer.
CAC = Total Sales & Marketing Costs ÷ Number of New Customers
This metric is essential for understanding how efficient your go-to-market efforts are. If your CAC is climbing faster than your LTV, it’s time to revisit your acquisition strategy.
NRR shows how much revenue you retain from your existing customers over a period, including upgrades, downgrades, and churn.
Now, your prospects are close to making a decision.
Guide your leads smoothly through this final stage to seal the deal and convert them into paying customers.
Churn tells you how many customers (or how much revenue) you’re losing over time. There are two types:
Logo Churn: Percentage of customers who cancel
Revenue Churn: Percentage of recurring revenue lost
High churn not only stalls growth but signals problems with onboarding, product-market fit, or customer experience.
ARPU helps you understand the revenue efficiency of your user base.
ARPU = MRR ÷ Total Number of Active Customers
It’s also helpful for comparing customer segments or pricing tiers.
This includes upsells, cross-sells, and any increase in revenue from existing customers. In SaaS, your most cost-effective growth often comes from the customers you already have.
Track expansion revenue to:
•Validate your upgrade strategy
•Measure the success of new product features
•Understand user satisfaction and stickiness
This metric helps measure how efficiently your team is contributing to revenue. While more common in later stages, it’s a helpful benchmark for scaling teams.
Tracking these metrics consistently helps you:
Diagnose growth issues early
Make strategic pricing decisions
Optimize sales and marketing efforts
Prove ROI to stakeholders and investors
A strong revenue metrics dashboard should be part of your executive reports and reviewed monthly or quarterly depending on your growth stage.
Growth in SaaS isn’t just about moving fast—it’s about moving smart. By focusing on the right revenue growth metrics, you get a clearer picture of your business performance and can make smarter decisions that lead to sustainable success.
Start with the basics—MRR, LTV, and CAC—and evolve your strategy as you scale.
