Update activity

How busy the existing users are, measured as downloads in the last 30 days for every 1,000 active sites. A spike means a new release everyone's pulling; a long, slow decline means an aging user base that updates less.

How often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Estimated value

What this plugin might earn a year, and what it might sell for. Modeled from public signals; we don't see anyone's books.

low confidence

Est. annual revenue

≈$560 range $160–$2K

Est. acquisition value

≈$1.1K range $240–$5K

A small install base leaves thin data to model from. A declining trend compresses what a buyer would pay. The range spans more than 10x because wp.org publishes install counts as broad bands, and conversion and price compound on top. Read the midpoint as an order of magnitude, not a valuation.

How we estimate this

Assumptions

  • Free → paid conversion. 0.5%–2% of active installs pay for the pro tier. Typical for freemium WordPress plugins; the real rate varies a lot by product.
  • Annual price per customer. $79–$199 a year, typical for Booking & Events plugins rather than this plugin's own pricing.
  • Acquisition multiple. 1.5x–2.5x annual revenue, the going range for small WordPress-plugin businesses, compressed because the install trend is declining.
  • Install base. 400–500 active installs, from our install estimate (wp.org only publishes the floor).

Revenue is installs × conversion × price; value is revenue × a typical acquisition multiple. Every factor is an assumption band, so the output is a wide range on purpose. If you're buying or selling, treat this as a starting point for due diligence.

    I had high hopes for this plugin for a private school website. But there are no instructions on how to actually add events or use categories, etc. And by the looks of the support forum, there is non-existent support for it.

    Its simple and works perfekt for our needs. we do not have huge events we need to announce that have to be filled with text and picture, location and much more. this is like the only plugin i could find and it fits perfect. i faced the same problems the user mentioned with the 1970 date error, but after contacting the support hte issue was solved asap and its running just fine. looking for further develompments. best regards

    You cannot enter dates, they all become January 1, 1970. It also does not allow descriptions of the events. Very limited and does not work.
