Upgrade/Downgrade Rate

What is upgrade/downgrade rate?

Upgrade/downgrade rate measures the percentage of subscribers who move between pricing tiers or subscription plans within a given period. An upgrade occurs when a customer shifts to a higher-value plan, while a downgrade happens when they move to a lower-cost option. This metric helps businesses understand subscriber mobility, pricing fit, and the effectiveness of packaging strategies.

Why upgrade/downgrade rate matters

  • Revenue optimization: Upgrades increase average revenue per user (ARPU), while downgrades highlight pressure points in pricing or feature adoption.
  • Customer health signal: Frequent downgrades may indicate dissatisfaction or price sensitivity, whereas upgrades reflect recognition of added value.
  • Retention strategy: By tracking this rate, teams can identify opportunities to encourage upsell while designing safeguards against churn risk tied to downgrades.

How to calculate upgrade/downgrade rate

Upgrade/Downgrade Rate = (Number of Subscribers Who Changed Plan ÷ Total Subscribers) × 100

For example, if 200 out of 5,000 subscribers upgraded or downgraded in a month, the rate would be 4%. This can be further split into upgrade rate and downgrade rate to get a clearer picture of movement in each direction.

Inclusions and exclusions

  • Include: All voluntary subscriber-initiated plan changes within the subscription model.
  • Exclude: Involuntary changes due to billing issues, free-to-paid conversions, or administrative adjustments outside customer control.

Upgrade/downgrade rate in subscription businesses

In subscription businesses, especially media and SaaS, this metric reveals how well offerings align with evolving customer needs. A healthy upgrade rate shows that subscribers are finding value in premium tiers, while spikes in downgrade activity may indicate affordability concerns or feature gaps. With Subsets, businesses can segment audiences to test different pricing prompts, monitor downgrade patterns before they turn into cancellations, and design personalized upsell journeys that maximize retention and lifetime value.

The depth and breadth of the results analysis we can generate from Subsets has been invaluable. We are aiming to turn validated experiments into 'always on' and let Subsets select subscribers for targeting and trigger the campaigns.
