アップセル、クロスセル、アップグレードによる既存顧客からの収益成長率を計算します。

Expansion Revenue Rate measures the percentage of revenue growth driven by existing customers through upsells, cross-sells, and plan upgrades. It is the most important sign of product-market fit because it shows that customers find increasing value in your product over time. High expansion rates compound growth - companies with 120%+ NRR grow without acquiring a single new customer. This metric is particularly important for investors evaluating SaaS companies because expansion revenue is higher-margin and more predictable than new business. This calculator helps you track how effectively you're growing your existing customer base.

この計算機の使い方

Enter your beginning MRR at the start of the period and the expansion MRR generated during that period from existing customers.
The calculator will show your expansion revenue rate as a percentage.
Track this monthly alongside churn rate to understand net revenue retention..

計算式と具体例

Expansion Revenue Rate = (Expansion MRR ÷ Beginning MRR) × 100:

For example: $15K expansion MRR on $100K beginning MRR = 15% expansion revenue rate.

This means existing customers grew their spending by 15% during the period through upgrades and cross-sells..

よくある質問

What is a good expansion revenue rate?expand_more

Above 20% annually is excellent. 12-15% is median. Below 5% suggests limited upsell opportunities or product limitations.

How is expansion revenue rate different from NRR?expand_more

NRR includes both expansion revenue and churn/contraction. Expansion revenue rate only measures the positive side - growth from existing customers.

What drives high expansion revenue?expand_more

Usage-based pricing (customers spend more as they grow), multi-product strategy (cross-sell adjacent products), and tiered plans with natural upgrade paths.

How do I increase expansion revenue?expand_more

Build usage-based pricing components, create clear upgrade paths between tiers, develop adjacent product features, implement a customer success team focused on growth, and identify power users for upsell. Monitor expansion revenue trends with Baremetrics.

How often should I track expansion revenue rate?expand_more

Monthly. Track alongside logo expansion rate (percentage of customers who expanded) for a complete picture of expansion effectiveness.

Does expansion revenue rate vary by customer segment?expand_more

Yes. Enterprise customers typically have higher expansion potential (20-40% annually) than SMB (5-15%). Segment by customer size for accurate benchmarking.

What is the relationship between expansion and churn?expand_more

Even modest expansion can offset churn. A 10% expansion rate can offset 10% revenue churn, resulting in 100% NRR. High expansion is the strongest predictor of long-term SaaS success.

How does product-led growth affect expansion?expand_more

PLG companies with usage-based pricing naturally drive expansion as customers grow. This creates a powerful flywheel: more usage → more value → more spend → more product investment.
