Freemium with a free plan, per-user monthly billing on Plus, and a fixed monthly flat-rate Pro Unlimited tier; optional paid upgrades are sold separately on Plus.
↻ Billing notes
Basecamp publicly offers monthly pricing on Plus and Pro Unlimited, with a 30-day free trial on the Free account and a 60-day free trial mentioned for Pro Unlimited. The company says no credit card is required to try Basecamp, and if you choose a pay package with a free trial, you enter payment details only at the end if you want to continue. The pricing page also says you can upgrade, downgrade, and cancel any time; annual-package cancellations are prorated back to the credit card. Non-profit customers receive 10% off if they are registered 501(c)(3) organizations, while K-12, homeschoolers, and universities are free for class work only.
Official pricing copy does not state a public dollar amount for the Free plan on the page text supplied. It is described as a single-project package elsewhere on the page, with one project at a time on the free package.

⚠ The official pricing page makes clear that some capabilities are optional upgrades on Plus, so buyers should budget for add-ons if they need time tracking, expanded admin controls, or more storage. The page also notes that clients and contractors are free, but employee or full-user seats are billed on Plus, which can materially change total cost as the team grows.
⚠ Basecamp also says cancellation is self-serve and that annual-package cancellations are prorated back to the credit card. That means there may be timing effects when changing plans, even though the company says there is no long-term lock-in.
