Chart: Free Trials
The Free Trials chart tracks the number of free trials over time.
For SaaS businesses, trial volume is a leading indicator of pipeline health — it sits at the top of the conversion funnel and directly influences future subscriber growth. Monitoring this chart alongside trial-to-paid conversion rate gives teams a complete view of how well their acquisition efforts are working.
If you're new to ChartMogul, get to know how charts work.
ChartMogul automatically imports lead and trial data from a number of our integrations. A free subscription is classified as a trial based on an invoice line item of the “trial” type. If your Free Trials chart appears empty, you may need to set up trial tracking. Learn more.
Chart Notes
Only customers with a Trial started at date contribute to this chart.
On October 2, 2025, we introduced a new “trial” line item type and are gradually making it available to all customers. If you have this feature enabled:
- Free Trials includes both customers with a Trial started at date and those with trial invoice line items.
- One customer can have multiple trials.
- You can filter Free Trials by plan. Plan filters exclude customers who have a Trial started at date but no trial invoice line items.
- If a customer has both a Trial started at date and trial invoice line items, ChartMogul ignores the Trial started at date.
Calculation
To calculate the number of trials, ChartMogul uses the number of customers who have a Trial started at date and the number of free subscriptions classified as trials (generated from invoice line items of the “trial” type). If a customer has both a free trial date and a free trial subscription, ChartMogul ignores the free trial date and only counts the free trial subscription. If a customer has multiple free trial subscriptions, ChartMogul counts each subscription separately.
Chart Data
The Chart Data table for Free Trials works differently than other charts. It provides the following breakdown:
- Free Trials — The number of customers with a
Trial started atdate. - Change — The increase or decrease in Free Trials from the previous report interval, shown as a percentage.
Select a Free Trials cell to see the list of free trials started in the reporting period.
