# ARR for Usage-Based Pricing: Quick Q&A Guide

A quick, simplified Q&A version of our main guide on calculating ARR when your pricing model includes usage.

## Understanding ARR + Usage

### Why is ARR harder to calculate when a product has usage-based pricing?

ARR is straightforward with [fixed subscription fees](/products/subscription-billing-software/) because the recurring amount is known. Usage-based fees fluctuate, making it harder to determine which portion is truly recurring.

### Why does usage variability matter?

Because the more revenue fluctuates month to month, the harder it is to classify as predictable or repeatable.

## When to Include Usage in ARR

### When should usage-based revenue be included in ARR?

When it is predictable and consistent over time, especially when viewed across the entire customer base.

### What patterns indicate predictability?

Month-over-month stability or consistent long-term behavior that recurs across customers.

## When to Exclude Usage from ARR

### When should usage-based revenue be excluded from ARR?

When usage varies significantly, is irregular, or does not repeat reliably.

### Why exclude inconsistent usage?

Because sporadic or unpredictable usage cannot reasonably be classified as recurring.

## Annualization Methods for Usage Revenue

### How do companies annualize usage-based revenue?

Common approaches include:

• Annualizing last month’s usage revenue (× 12)

• Annualizing last quarter’s usage revenue (× 4)

• Using trailing 12-month usage revenue (× 1)

### Which approach is best?

Any of the above can work as long as the method is consistent and clearly documented.

### What if usage is seasonal?

If usage is seasonal but consistent year over year, average it across a 12-month period to determine the recurring portion.

## Segment and Seasonality Considerations

### What if some customer segments show predictable usage and others don’t?

Include usage-based revenue for consistent segments and exclude it for segments with irregular patterns.

### Why separate segments?

Because different customer groups may inherently behave differently, and mixing inconsistent data can distort ARR.

## Combining Subscription + Usage for Total ARR

### How do you combine subscription revenue and usage-based revenue to get total ARR?

• Calculate ARR for fixed subscription fees
• Annualize the recurring portion of usage-based revenue
• Add the two together to form total ARR

### Why calculate them separately?

Because fixed fees and usage-based fees behave differently and require [different logic](/faqs/how-do-billing-platforms-handle-proration-and-billing-adjustments/) before combining.

## Governance & Internal Alignment

### What should companies do before finalizing an ARR methodology?

• Document the calculation method
• Align internally or obtain board approval
• Train [accounting, rev ops, billing, and FP&A teams](/blog/success-with-usage-based-pricing-requires-collaboration-across-business/)
• Embed the method in systems, spreadsheets, and processes
• Communicate the methodology externally to investors and stakeholders

### Why is consistency important?

Because ARR is a key growth metric, and inconsistent calculations erode credibility.

## One-Sentence Takeaway

[Accurate ARR for usage-based pricing](/products/investor-metrics/arr-reporting-software/) requires clear rules on predictability, a consistent annualization method, and disciplined internal alignment.
