How to Calculate Price Elasticity for SaaS: A Step-by-Step Guide
To know how price changes might affect your subscription revenue, calculate the ratio of the percentage change in quantity demanded to the percentage change in price. Calculating price elasticity shows how sensitive your customers are to cost before you update your pricing.
This guide provides the process for quantifying these changes, which helps you make decisions based on data related to expansion and retention.
Audit customer habits and "stickiness"
Start by assessing your current market position before making any calculations. SaaS products fall into two categories:
Elastic (where demand drops significantly when price rises) or Inelastic (when demand remains stable despite price rises).
In the B2B context, elasticity isn’t a straight line but more of a curve that is influenced by the Product-Led Growth (PLG) cycle and the maturity of your SaaS branding.
Try these self-assessment questions for strategy selection:
- Switching Costs: How much effort is required for a user to export data and move to a competitor’s product? High technical debt for the user usually results in inelasticity.
- Relevancy: Is the tool required for daily operations, or is it a feature you can do without?
- Market Share: Does your SaaS branding position you as the obvious choice in your niche?
- Budget Authority: Who pays for the tool? A developer’s use of a tool funded by corporate procurement may present different elasticity traits compared to an indie developer that pays directly.
If your software is considered critical, you likely have low price elasticity of demand, allowing for higher margins. If your software is more of a nice-to-have option in the market, utilize B2B brand awareness strategies that will improve the perceived value before raising prices. Many companies have discovered that offering tiered pricing helps satisfy different levels of elasticity across their customer segments.

Establish your baseline and Segment your cohorts
Create a specific group of users and document their behavior over a set period (typically 6–12 months). You will need the starting price and the average number of active subscriptions. However, a “clean” baseline requires removing noise from seasonal churn. Use a SaaS churn rate calculator to understand your current baseline of lost users before making any changes.
Separate your baseline by geography. For example, a startup that sells to Germany may experience different elasticity than one that is selling to Brazil due to local purchasing power.
A “clean” baseline is more than just a list of users; it is a segmented view of your Net Revenue Retention (NRR) potential.
- The Noise Filter: Isolate “Acquisition Elasticity” from “Retention Elasticity.” New leads are naturally more price-sensitive than existing users who have already integrated your product into their workflow.
- The Seasonality Guardrail: Ensure your baseline excludes “budget flush” periods (e.g., Q4 for Enterprise) or seasonal troughs, which can create a false signal of inelasticity.
- Metric Focus: Track MRR by Seat/Usage specifically. If you are selling to high-compliance markets, ensure your baseline accounts for localized Purchasing Power Parity (PPP).
Use “Active Paid Subscriptions” rather than “Registered Users.” If you are implementing freemium pricing, free-tier users do not contribute to price elasticity for SaaS calculations because their starting price is zero, which negates the standard price elasticity formula.

Implement a controlled price adjustment
Choose a specific segment of your audience or a certain geographic region to test the new price. This is sometimes referred to as the “Van Westendorp Price Sensitivity Metering” in advanced circles.
Case study: The digital whiteboarding platform Miro sorted its pricing tiers to better reflect its value as a collaboration hub. By isolating the change to new sign-ups first, they were able to measure the delta in conversion rates without triggering immediate customer churn in their current user base. This allowed them to calculate elasticity while considering possible effects on their primary revenue stream.
Samsara, a vertical SaaS provider for the logistics industry, experienced revenue changes with a shift from hardware sales to a comprehensive SaaS subscription model. They found that the addition of safety features influenced demand elasticity, which potentially had an impact on their average revenue per account (ARPA).

Apply the Price Elasticity Formula
Adopt the Midpoint Formula to determine your score. This method is the preferred strategy in SaaS financial management because it provides the same elasticity value regardless of whether the price increases or decreases.
The Midpoint Method is used because the results of standard percentage change calculations may differ depending on the direction of the change. Increasing the price from $10 to $15 represents a 50% change. Reducing it from $15 to $10 represents approximately a 33% decrease. The Midpoint Method addresses the ‘base-point’ concern, which is key for SaaS pricing optimization.

Analyze revenue sensitivity and CAC correlation
Compare the elasticity coefficient to your Customer Acquisition Cost (CAC).
- Result < 1 (Inelastic):
Congratulations, you have “pricing power”; a price increase may correlate with a change in total revenue, influenced by the relative magnitudes of user decrease and per-user revenue increase.
- Result > 1 (Elastic):
Your product is price-sensitive; there may be a relationship between a price increase and total revenue, where an increase might affect total revenue. In this case, focus on SaaS lead generation to replace lost volume.
When analyzing your results, look beyond the binary “Stay vs. Churn” outcome. You must account for Cross-Price Elasticity (Cannibalization).
- The Downshift Risk: If your coefficient for a “Pro” plan hike is high, analyze how many users didn’t leave, but instead “downgraded” to your “Starter” tier. This protects your user count but dilutes your ARPU (Average Revenue Per User).
- CAC Correlation: If your product is Elastic (Result > 1), your LTV:CAC ratio is at risk. Any price increase must be met with a corresponding increase in B2B Brand Awareness or perceived utility to “pull” the curve back toward inelasticity.
Expensify noticed that for SMB SaaS users, price sensitivity was higher than for their enterprise SaaS clients. To resolve this, they used SaaS price anchoring—presenting a much higher-priced custom plan that makes the standard tiers feel more affordable.

High Elasticity? Fine-tune your B2B brand awareness strategy
If your data shows high elasticity, your product is more than likely viewed as a commodity. To counter this, your B2B brand awareness strategy should shift its focus from features to outcomes.
Below are listed three major B2B Brand Awareness Tactics for Elastic Products:
- Integration partnerships: Clearly demonstrate how your tool can be integrated into any existing workflows.
- Community Building: SaaS community building has been proven to influence customer loyalty.
- Thought Leadership: Leverage whitepapers that highlight the pain points your tool manages, especially those less frequently addressed by competitors.
If your software is highly elastic, consider offering usage-based billing. This shows a direct correlation between costs and the value received by the customer, thus reducing the perceived price sensitivity compared to a flat-rate fee.
Once you know what your base elasticity is, you can refine it by using SaaS charm pricing. Remember, this is where your prices end in “.9” or “.99” to psychologically reduce the perceived cost.
Additionally, look at SaaS odd-even pricing. For premium SaaS branding, even numbers ($100) signify quality and simplicity, whereas odd numbers ($97) represent a bargain. If your elasticity is high (>1), odd pricing may help maintain volume during a price hike.

See the impact of elasticity on SaaS valuation
Gaining an understanding of your SaaS price elasticity isn’t only relevant for operational revenue; it’s also the basis of your SaaS valuation calculator inputs. Investors tend to look for pricing power as a sign of a healthy SaaS ecosystem.
If you can clearly articulate how your product is inelastic, your ARR multiple will increase. This is because inelasticity suggests a “moat” which is a competitive advantage that prevents SaaS churn even when market conditions change.

The "Post-Mortem" – churn and tax compliance
Price elasticity is never static. You should conduct customer churn analysis 90 days after every price modification. Furthermore, price increases often lead to higher annual recurring revenue (ARR), which can trigger new legal obligations.
The 120-Day Window: For Enterprise SaaS, the true impact of a price change may not surface until the next renewal cycle.
The Tax Nexus Trap: As you raise prices, your revenue in specific states (like New York or Texas) may cross the threshold for economic nexus. You would then be legally required to collect and remit SaaS sales tax. Failure to consider this in your elasticity model will lead to significant hidden costs in penalties. But using a Merchant of Record can help automate this compliance as you scale.
- High Elasticity: This can be due to external factors, such as a sudden market downturn. Always compare with benchmarks from SaaS industry market trends.
- Lagging Indicators: Churn is not necessarily limited to the initial month. Be sure to check your SaaS retention rate calculator over a 120-day timeframe.
- Feature Overlap: When price increases coincide with the introduction of a new product development strategy, the measurement reflects value acceptance in addition to, or instead of, price elasticity.
Conclusion
Precisely calculating SaaS price elasticity requires using the Midpoint Formula, which compares the percentage change in user volume against the percentage change in subscription cost. By using the price elasticity formula, you will be able to understand if the B2B brand awareness tactics are successfully protecting the product from price sensitivity. Monitoring price elasticity metrics offers valuable insights on the correlation between pricing strategies and value-driven revenue growth. Analyzing the elasticity coefficient provides data that may influence the evolution from a startup mindset to an enterprise revenue model.
FAQ
-
A coefficient of less than 1.0 is considered ideal, because it shows inelastic demand where customers are not highly sensitive to price changes. This gives businesses the opportunity to raise prices to grow revenue without experiencing a significant loss in subscriber base.
-
They should effectively perform this calculation annually or whenever a significant change in the competitive landscape occurs. Regular monitoring will ensure that your SaaS pricing optimization is relevant to current market demand.
-
Directly, it does not, because elasticity requires a non-zero starting price. Although SaaS free trials can lower long-term elasticity. By showing users the value of the product first, you lower their sensitivity to the eventual subscription cost.
-
High elasticity usually happens when there are many low-cost competitors or when the SaaS branding hasn’t shown how their product differs. If customers perceive your tool as a commodity, they tend to switch providers over minor price fluctuations.
-
Yes, a strong B2B brand awareness process can raise the perceived value and unique utility of your software. When customers trust a brand as the market leader, they are more inelastic and less likely to churn when any price adjustments occur.
-
Enterprise elasticity is configured by tracking seat expansion and contract renewals after a price hike. Because enterprise SaaS involves long-term service level agreements, elasticity is calculated over a 12-to-24-month period rather than a monthly timeframe.
-
In standard economics, elasticity is almost always negative because demand drops as price rises. However, we use the absolute value for simplicity. A rare “Veblen effect” occurs if a higher price actually increases demand by signaling elite status, though this is uncommon in B2B software.
