Basecamp Pricing in 2026: When the Flat $299 Plan Beats Per-User Billing
Basecamp costs $0 on its Free plan, $15 per user per month on the Plus plan (employees only, billed monthly), and a flat $299 per month billed annually — or $349 per month billed monthly — on Pro Unlimited, which drops the per-seat charge entirely and gives you unlimited users. That flat option is the unusual part: most project management tools bill you per person forever, so a growing team’s cost climbs with every hire. Basecamp caps it.
Prices and limits change, so confirm the current numbers on Basecamp’s official pricing page before you buy. Here’s how the three plans actually break down, and the exact team size where the flat plan starts saving you money.
Basecamp plans at a glance
| Plan | Price | Billing | Users | Storage |
|---|---|---|---|---|
| Free | $0 | — | Up to 20 | 1 GB |
| Plus | $15 per user/mo | Monthly, per employee | Unlimited | 500 GB |
| Pro Unlimited | $299/mo | Annual (or $349/mo monthly) | Unlimited | 5 TB |
Clients and contractors are always free to add on every plan — only employees (full users) count toward the Plus per-seat charge.
Free
The Free plan is a permanent tier, not a trial. You get 1 project, 1 GB of storage, and up to 20 users, plus Basecamp’s core toolset: message boards, to-dos, card tables, Campfire chat and Pings, the schedule, docs and files, and check-ins. Support is 24/7/365 even on the free tier. The single-project cap is the real ceiling here — it’s fine for one small team running one initiative, but you’ll hit the wall the moment you need a second workspace.
Plus
Plus is the per-user plan at $15 per user per month, billed monthly. It unlocks unlimited projects, bumps storage to 500 GB, and keeps the full core feature set. The seat-counting rule is genuinely generous: you only pay for employees and full users, while clients and contractors are added for free. A five-person agency serving 40 clients pays for five seats, not 45.
Two things to watch on Plus: some capabilities are paid add-ons rather than included. Timesheet and the Admin Pro Pack each run $50/month, and extra storage is $50/month per additional terabyte. Those add-ons are what make the flat plan’s all-in bundle attractive as you scale.
Pro Unlimited
Pro Unlimited replaces per-seat billing with a single flat rate: $299/month when billed annually (that’s $3,588 for the year) or $349/month if you pay month to month. For that you get unlimited users, unlimited projects, and 5 TB of storage. The Timesheet and Admin Pro Pack add-ons that cost extra on Plus are included here, and you get priority support with personal onboarding. It also accepts payment by check, ACH, and wire — a sign it’s aimed at larger orgs and procurement teams.
This flat-price model is unusual in the category and reflects 37signals’ bootstrapped, no-VC stance: they’d rather charge a predictable capped fee than meter you per seat as you grow.
When flat pricing wins
The math is simple. Plus costs $15 per employee per month. Pro Unlimited’s annual rate is $299/month no matter how many people you add. Divide $299 by $15 and you get ~20 users — that’s the break-even. Below it, Plus is cheaper; above it, the flat plan wins and keeps winning.
| Team size (employees) | Plus (per-user/mo) | Pro Unlimited (annual/mo) | Cheaper |
|---|---|---|---|
| 5 | $75 | $299 | Plus |
| 15 | $225 | $299 | Plus |
| 25 | $375 | $299 | Pro Unlimited |
| 50 | $750 | $299 | Pro Unlimited |
At 25 employees you’re already saving $76/month on the flat plan; at 50 you’re saving $451/month. If you compare against Pro Unlimited’s monthly rate of $349 instead, the break-even shifts to roughly 24 employees ($349 ÷ $15). And remember the add-ons: if your team on Plus needs Timesheet plus the Admin Pro Pack, that’s another $100/month, which pulls the real break-even down further because both are bundled into Pro Unlimited for free.
Gotchas that don’t show up in the headline price
- Annual vs monthly on Pro Unlimited is a real gap. $299/month billed annually vs $349/month billed monthly is a $600/year difference for the same plan. If you’re committed, annual is the obvious choice.
- Plus add-ons stack up. Timesheet ($50/mo), Admin Pro Pack ($50/mo), and extra storage ($50/mo per TB) are billed on top of your per-seat cost. A mid-size Plus team can quietly spend more than the flat plan once these are added.
- Storage caps are per plan, not per user. Free gives you 1 GB total, Plus 500 GB, Pro Unlimited 5 TB. File-heavy teams (design, video, construction) burn through 500 GB faster than you’d expect.
- The “free guests” rule is about billing, not access. Clients and contractors get full project access without counting toward your seat charge — but they’re still real users in your account, so factor them into how you organize projects and permissions.
Is Basecamp free?
Yes, permanently — but with hard limits. The Free plan gives up to 20 users, 24/7 support, and the full core feature set, capped at 1 project and 1 GB of storage. It’s a genuine free tier rather than a time-limited trial, which makes it viable for a single small team running one project indefinitely. Need a second project or more space and you move to Plus (which also offers a 30-day free trial) or Pro Unlimited (60-day trial). Nonprofits get 10% off, and K-12 schools and universities can use Basecamp free for classwork.
When Basecamp isn’t the right fit
Basecamp’s pricing is refreshingly simple, but the product is deliberately opinionated — flat structure, no custom fields or advanced automations, no Gantt-style dependency chains. If your team needs those, the flat price won’t matter. Two comparisons worth reading before you commit: our roundup of Basecamp alternatives for teams that have outgrown its simplicity, and the head-to-head on Basecamp vs Asana if you’re weighing structured task management against Basecamp’s calmer approach. For a per-seat comparison, Asana pricing and Monday pricing both bill per user, so run the same break-even math against your headcount before choosing.

"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
