Key features
Who should use Cal.com?
If you are a Solo / freelancer...
The free plan covers the basics. You will probably not need to upgrade until you hit the limits of the Free plan.
If you are a 5-person startup...
Start on the free plan and upgrade when collaboration features become essential. Budget around $75/mo for a team of five on the paid plan.
If you are a 50+ person company...
You will likely need the Teams plan or above. At this scale, check the workflow automations and payment collection capabilities — they matter more as teams grow.
Pricing: the honest take
The free plan is genuinely useful for unlimited bookings and routing forms — not just a teaser. You can run real work on it. When you outgrow it, the jump to Teams at $15/mo is reasonable.
