Basecamp pricing explained
A free plan for one project, a simple per user step, and a flat rate that turns unlimited users into one fixed bill.
Basecamp prices itself unlike almost anyone else in the category. The free plan runs one project for up to twenty users; Plus bills a flat $15 for each employee with unlimited projects; and Pro Unlimited charges one fixed $299 a month for unlimited users, which is the headline that defines Basecamp's economics. Clients and contractors are free on every plan. The decision is mostly about headcount, since the flat plan overtakes per seat billing at around twenty paid users. Below are all plans as of June 2026, then a plain look at what moves the cost.

Is Basecamp free?

As of June 2026, the Plus plan is $15 per user per month and bills only for employees, not clients or contractors. The Pro Unlimited plan is a flat $299 a month for unlimited users. Check the vendor for current pricing.
When is Pro Unlimited cheaper than Plus?
Plus at $15 per user reaches the $299 flat rate of Pro Unlimited at about twenty paid users. Above roughly twenty employees, the flat Pro Unlimited plan is the cheaper option and removes per seat math entirely.
Does Basecamp charge for clients?
