Short answer: Thinkific charges 0% platform fee on its TCommerce processor and 1-5% surcharge on every transaction if you use your own Stripe (5% on Basic, 2% on Start, 1% on Grow). At $5,000/month in revenue on Basic with own Stripe, that's $250/month — $3,000/year — in fees that don't appear on Thinkific's pricing page. The processor choice matters as much as the plan choice.

What Is TCommerce and How Is It Different From Your Own Stripe?
TCommerce is Thinkific's built-in payment processor. Under the hood it uses Stripe Connect, but the Stripe relationship is owned by Thinkific — meaning your students pay through Thinkific's payment infrastructure rather than your direct Stripe account. Functionally, customer experience looks the same: card checkout, recurring billing, refunds. The differences are structural.
With TCommerce: Thinkific charges 0% platform fee. Transactions appear in Thinkific's dashboard. Tax reports, refunds, and disputes are managed through Thinkific's interface. Active subscription billing relationships are tied to Thinkific.
With your own Stripe: Thinkific charges a 1-5% platform surcharge depending on tier. Transactions appear in your Stripe dashboard. You manage tax, refunds, and disputes directly in Stripe. Subscriptions live in your Stripe account and survive a platform migration cleanly.
What's the Surcharge by Plan?
From Thinkific's own pricing structure, here's the own-Stripe surcharge by tier:
| Thinkific plan | TCommerce fee | Own-Stripe surcharge |
|---|---|---|
| Basic ($36/mo annual) | 0% | 5% |
| Start ($74/mo annual) | 0% | 2% |
| Grow ($149/mo annual) | 0% | 1% |
| Plus (custom) | 0% | Custom |
Note: all four tiers charge 0% on TCommerce. The surcharge only kicks in when you bring your own Stripe account. Both options sit on top of Stripe's standard processing (2.9% + 30¢ for US cards, +1% for international).
What Does the Surcharge Cost at Each Revenue Level?
The surcharge scales linearly with revenue. Here's the monthly own-Stripe surcharge by plan and revenue level (this is on top of the monthly plan price and standard Stripe processing fees):
| Monthly revenue | Basic (5%) | Start (2%) | Grow (1%) |
|---|---|---|---|
| $1,000 | $50 | $20 | $10 |
| $2,500 | $125 | $50 | $25 |
| $5,000 | $250 | $100 | $50 |
| $10,000 | $500 | $200 | $100 |
| $25,000 | $1,250 | $500 | $250 |
At $5,000/month on Basic with own Stripe, the surcharge alone ($250) is 7× the plan price ($36). Annual cost of the surcharge at that revenue: $3,000. For comparison, Thinkific Basic plan + surcharge totals $286/month, while Thinkific Start with own Stripe at the same revenue is $74 plan + $100 surcharge = $174/month — substantially cheaper because the higher-tier surcharge percentage is lower.
When Does Upgrading Tiers Save Money on Own-Stripe?
Because the surcharge percentage drops as you upgrade, there are revenue thresholds where upgrading actually saves money for own-Stripe users. The math:
- Basic → Start breakeven (own Stripe): $1,267/month in revenue. Below that, Basic + 5% surcharge is cheaper than Start + 2% surcharge. Above $1,267/mo, Start saves money despite the higher plan price.
- Start → Grow breakeven (own Stripe): $7,500/month in revenue. Below that, Start + 2% is cheaper than Grow + 1%. Above $7,500/mo, Grow saves.
Derivation for Basic → Start: $36 + 0.05R = $74 + 0.02R → 0.03R = $38 → R = $1,267. Derivation for Start → Grow: $74 + 0.02R = $149 + 0.01R → 0.01R = $75 → R = $7,500.
Practical implication for own-Stripe users: if you're at Basic doing more than $1,267/month, you save money by upgrading to Start. If you're at Start doing more than $7,500/month, you save money by upgrading to Grow. The TCommerce path doesn't have these breakevens because there's no surcharge to optimize away — you just pay the plan price.
What Are the Non-Financial Trade-Offs?
If you sell memberships or payment plans, the most important difference isn't the surcharge percentage — it's subscription portability. The math isn't the whole picture. Several structural differences between TCommerce and own-Stripe matter beyond what's on the pricing page:
| Consideration | TCommerce | Own Stripe |
|---|---|---|
| Platform fee | 0% | 1-5% |
| Subscription portability if you leave Thinkific | Locked (subscribers re-subscribe) | Portable (lives in your Stripe) |
| Stripe dashboard access | No (Thinkific dashboard only) | Yes |
| Tax reporting | Through Thinkific | Through Stripe |
| Refund and dispute handling | Through Thinkific | Direct in Stripe |
| Setup simplicity | One-click | Stripe Connect setup |
The biggest non-financial consideration is subscription portability. If you're running memberships or payment plans through TCommerce and later decide to leave Thinkific, your subscribers don't port to a new platform — they need to cancel and re-subscribe. This is structurally identical to the Kajabi Payments lock-in problem. For one-time course sales, the lock-in doesn't matter. For subscription-driven businesses, it's the most important factor in the choice.
Which Should You Choose?
The decision usually comes down to three questions:
- Are you running subscriptions or memberships? If yes, own Stripe is the safer long-term choice — portable, your relationship with the customer survives any platform migration. The surcharge is the cost of preserving that flexibility.
- Are you doing more than $1,267/month on Basic, or more than $7,500/month on Start? If yes and you're on own Stripe, upgrade the tier. The lower surcharge percentage on the higher tier saves more than the plan-price difference costs.
- Do you have existing Stripe customer relationships you want to preserve?If yes, own Stripe. If you're starting fresh and your business is mostly one-time purchases, TCommerce is the simpler default.
For context on the upper edge of what Thinkific's tier structure can hold: Christine Valters Paintner at Abbey of the Arts runs 367 active courses with roughly 18,000 students through deep community engagement. Thinkific's 10,000 student cap on every standard tier (Basic/Start/Grow) would force her onto Plus enterprise pricing regardless of processor choice. For broad-catalog teaching businesses near or past 10K students, the processor question becomes secondary to the cap question.
How Does This Compare to Other Platforms?
Thinkific's processor-choice surcharge structure isn't unique — it's similar to Kajabi's split (Kajabi Payments has 0% Kajabi fee but 0.7% subscription surcharge, own Stripe has 0.5-2% Kajabi surcharge). For a fair comparison at the processor question specifically:
- Thinkific Basic + own Stripe — $36/mo plan + 5% surcharge ($250 at $5K revenue)
- Kajabi Basic + own Stripe — $143/mo plan + 2% surcharge ($100 at $5K revenue), plus 0.7% subscription surcharge if applicable
- Teachable Builder — $69/mo plan + 0% Teachable platform fee (just standard Stripe)
- Ruzuku Core — $99/mo + 0% Ruzuku fee on every processor (no surcharge structure)
For creators bringing existing Stripe relationships, Teachable Builder and Ruzuku Core are the cleanest options — no platform surcharge on top of standard Stripe processing. For creators willing to use TCommerce, Thinkific Basic is the cheapest path. The full breakdown is in our Thinkific alternatives roundup.
Bottom Line
Here's the version I'd give a friend: Thinkific's "0% transaction fees" marketing is accurate only if you use TCommerce. If you bring your own Stripe — which most creators with existing customer relationships do — the surcharge structure creates three clean thresholds on own Stripe:
- Under $1,267/mo: Basic ($36/mo annual, 5% surcharge) is cheapest.
- $1,267 to $7,500/mo: Start ($74/mo annual, 2% surcharge) wins.
- Above $7,500/mo: Grow ($149/mo annual, 1% surcharge) wins.
Or commit to TCommerce on any tier and accept the subscription lock-in in exchange for the 0% platform fee. The choice between own-Stripe-plus-surcharge and TCommerce-with-lock-in is the real decision; the tier upgrade question follows from your revenue level.

One more thought, since we build a competing platform. If the own-Stripe surcharge structure feels wrong for your business — if you want a platform that doesn't charge a premium for using your own processor — that's the structural problem Ruzuku solved by not having a processor-choice fee at all. 0% Ruzuku fee on every plan regardless of processor. The free tier is the no-pressure way to test the difference on one course.
