Definition:
New Subscriptions is a subscription metric that counts first-time paid subscriptions activated during a selected reporting period. It shows how many acquired users move into a paying subscriber relationship for the first time.
What Are New Subscriptions?
A new subscription begins when a user completes their first successful paid subscription transaction for a subscription product. This is a major step in the subscriber lifecycle because it marks the point where an acquired user becomes a paying subscriber.
A typical subscription journey might look like:
Install → Trial → New Subscription → Renewal → Cancellation or Expiration
Not every user follows this exact path. Some users subscribe immediately without a trial. Others start a trial but never convert to paid. The New Subscriptions metric focuses specifically on the first paid activation. It does not count later recurring payments as new subscriptions. Later payments tied to the subscription cycle are considered renewals.
New Subscriptions vs. New Trials
New Trials measure trial starts. New Subscriptions measure first-time paid subscription activations.
Example: A mobile fitness app generates 2,000 New Trials and then 600 New Subscriptions. Only a fraction of the trial group becomes paid. If all 600 paid subscribers came from the trial population, a simplified trial-to-paid conversion rate would be 30%.
Some users may also subscribe without a trial, so teams should understand how their reporting system defines conversion paths. For user acquisition, the key point is that a trial start is not the same as revenue. New Subscriptions is a deeper conversion event.
New Subscriptions vs. Renewals
New Subscriptions counts the first paid subscription activation. Renewals count existing subscriptions that successfully process another recurring payment.
Consider a user who pays $10 per month for four months. The lifecycle includes one New Subscription in the first month and three subsequent renewals. This separation helps teams understand whether growth is coming from acquiring more new paying users or from retaining existing subscribers.
How Do You Calculate Subscription Conversion Rate?
Subscription conversion rate can be defined in different ways depending on the funnel stage used as the denominator.
A common formula:
Subscription Conversion Rate = New Paid Subscriptions ÷ Acquired Users × 100
Example: A campaign generates 5,000 installs and 250 New Subscriptions.
250 ÷ 5,000 × 100 = 5% install-to-subscription conversion rate
Another team may calculate trial-to-paid conversion instead:
500 New Subscriptions ÷ 1,500 New Trials × 100 = 33.3% trial-to-paid conversion
Both calculations are useful, but they answer different questions. Before calculating, teams should define the denominator clearly when discussing subscription conversion rate.
New Subscriptions and Subscriber Acquisition Cost
New Subscriptions is also the denominator for a useful acquisition-efficiency metric: subscriber acquisition cost.
The formula:
Subscriber Acquisition Cost = Acquisition Spend ÷ New Paying Subscribers
Example: A campaign spends $15,000 and generates 500 New Subscriptions.
$15,000 ÷ 500 = $30 per new subscriber
That number becomes more meaningful when compared with subscriber LTV. If the average subscriber eventually generates $80, a $30 acquisition cost may support profitable growth. If the average subscriber generates only $20, the acquisition economics are much weaker.
Measure New Subscriptions by Campaign
An MMP connects the first paid subscription event with acquisition information. This allows marketers to compare New Subscriptions by dimensions such as network, campaign, creative, country, platform, Product ID, and acquisition cohorts.
These breakdowns reveal the shape of acquisition and make it possible to connect spend and sources directly to paid conversions.
New Subscriptions and New Subscription Revenue
New Subscriptions is a count. New Subscription Revenue is a monetary value. Two campaigns can generate the same number of new subscribers but very different revenue.
Example:
- Campaign A: 100 New Subscriptions on a $10 monthly plan → $1,000 New Subscription Revenue
- Campaign B: 100 New Subscriptions, mostly on a $50 annual plan → $5,000 New Subscription Revenue
The subscriber count is identical; the first-payment revenue is not. This is why Product ID and plan mix matter when interpreting New Subscriptions.
New Subscriptions and Cohort Maturity
New Subscriptions usually appear earlier than renewal revenue, but timing still matters. A cohort with a 14-day free trial will take longer to produce paid subscriptions than a cohort with no trial or a three-day trial.
Campaign A may appear to have fewer New Subscriptions simply because a larger share of its users are still inside the trial period. A fair comparison measures paid conversion after enough time for each cohort to complete its trial.
How Tenjin Supports New Subscription Measurement
Tenjin’s iOS Subscription Revenue Report connects New Subscriptions with the wider subscription lifecycle and acquisition data. The report includes:
- New Trials
- New Subscriptions
- New Subscription Revenue
- Renewals
- Renewal Revenue
- Cancellations
RevenueCat and Adapty integrations are supported for teams using those platforms to manage subscription events. This means the new subscription is not treated as an isolated conversion. It can be evaluated alongside what happened before it and what happens afterward. The strongest acquisition source is not always the one generating the most first-time paid conversions. It may be the one generating subscribers who renew, retain, and create the highest long-term value.
Best Practices for Measuring New Subscriptions
- Define a new subscription as the first successful paid activation.
Do not mix first payments with renewals. - Measure paid conversion by acquisition source.
Blended subscriber counts can hide campaign differences. - Compare subscriber acquisition cost.
New subscription volume becomes more useful when connected with spend. - Track Product ID.
Different plans can produce very different revenue and retention behavior. - Follow subscribers into renewal.
The first paid transaction does not reveal full subscriber quality. - Account for trial timing.
Give cohorts enough time to complete the trial before comparing conversion. - Compare subscriber LTV.
More subscribers do not automatically mean more profitable growth.

Frequently Asked Questions
What are New Subscriptions?
New Subscriptions are first-time paid subscription activations during a selected reporting period.
Is a New Subscription the same as a trial?
No. A trial is a pre-paid-conversion stage, while a New Subscription represents a first successful paid subscription.
Is a renewal counted as a New Subscription?
No. Later recurring payments from an existing subscriber are renewals, not new subscriptions.
Why should marketers track New Subscriptions by campaign?
It shows which acquisition sources convert users into paying subscribers rather than only generating installs or trials.
Are more New Subscriptions always better?
Not necessarily. Subscriber quality also depends on plan value, renewal behavior, cancellation, LTV, and the cost of acquisition.
