How freemium works
A freemium product has a free plan with limits: a number of projects, users, messages or storage, or a set of features left out. Customers use it as long as they like without paying. When they hit a limit or need a missing feature, they upgrade to a paid plan.
A free plan is not a free trial. A trial gives the full product for a set time and then asks for payment; a free plan never ends, but it never gives everything. Some businesses offer both: a free plan forever, plus a trial of the paid plan.
The number that matters is the free-to-paid conversion rate: the share of free users who move to a paid plan in a period. Because free users cost something to serve, the limits have to be set so that a growing customer reaches them.
free-to-paid conversion rate = users who upgrade in the period ÷ free users at the start of the period
Worked example
A note-taking app has 2,000 users on its free plan at the start of the quarter. The paid plan costs $15 a month, and 60 free users upgrade during the quarter.
- Free users at the start of the quarter
- 2,000
- Free users who upgrade
- 60
- Free-to-paid conversion: 60 ÷ 2,000
- 3%
- New MRR from the upgrades: 60 × $15
- $900.00
The 1,940 who stayed free add $0 of MRR. They count as users, not as paying customers.
Why freemium matters
A free plan removes the hardest step, the first payment, so people can adopt the product without asking anyone for a budget. When it works, free users bring in colleagues and the product spreads before a sale is ever made.
It is also a cost. Every free user uses servers and support, and a free plan that is too generous gives customers no reason to pay. Freemium works when the free plan is useful and the paid plan is clearly worth more to anyone who grows.
Common mistakes
- A free plan with no reason to upgrade If the free plan covers everything most customers need, most will never pay. Put the limit where growing customers meet it.
- Counting free users as customers Free users are not MRR and not paying customers. Report them separately, or growth numbers look better than revenue.
- A hard wall with no path forward When a free user hits a limit, show what the paid plan adds and let them upgrade on the spot, not a bare error.
