What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Substack is the better fit if you want a publication-centered workflow for free and paid writing; WordPress.com is stronger if you need a broader website, plugin extensions, or more room to customize. Substack takes 10% of paid subscription revenue, while WordPress.com’s subscription transaction fee varies by plan from 0% to 10%. Neither is universally cheaper or better: your choice depends on expected subscription income, site needs, and how much you value portability.
This comparison is specifically about WordPress.com, the hosted service—not WordPress.org software installed with independently chosen hosting, whose costs depend on the host and setup.
How the two platforms differ
Substack centers on a publication: writers can publish free or paid posts, offer subscriptions, and use integrated publishing features such as podcasts. WordPress.com can also support publishing, but its broader website focus makes it a better match when the publication needs to sit alongside other pages or use plugin-based extensions.
WordPress.com says its marketplace offers more than 60,000 plugins. Substack emphasizes an integrated publication workflow. These differences are more useful than a blanket ease-of-use ranking: the official product descriptions do not establish that one platform is objectively easier to use.

Compare the costs that affect your decision
| Cost | Substack | WordPress.com |
|---|---|---|
| Publishing or site plan | Publishing is free regardless of subscriber count, according to Substack’s pricing article updated September 29, 2026. Paid subscriptions add fees described below. | Paid plans begin at $4 per month when billed annually, according to WordPress.com’s creator page. The price is a starting point, not a complete cost estimate for every site. |
| Platform fee on paid subscriptions | 10% of each paid subscription payment, according to Substack’s pricing article updated September 29, 2026. | 0–10%, depending on plan, according to WordPress.com’s paid-subscriptions page. That page does not provide enough plan-by-plan detail here to calculate a precise comparison. |
| Payment processing | Substack lists U.S. card processing at 2.9% + $0.30 per payment and a 0.7% Stripe Billing fee for recurring payments. Other payment methods and account geographies may have different rates. | Standard Stripe processing fees also apply. The reviewed WordPress.com page does not state a specific processing rate. |
| Custom domain | $50 USD as a one-time fee to connect a custom domain, according to Substack’s domain help article updated April 29, 2026. | A custom domain is included with paid plans, according to WordPress.com’s creator page. |
The domain charges are different kinds of costs: Substack’s figure is a one-time connection fee; WordPress.com’s $4-per-month starting price is for a paid plan billed annually. They should not be treated as directly equivalent charges. See Substack’s pricing details, WordPress.com’s paid-subscriptions details, and Substack’s custom-domain instructions.
Estimate fees against your own revenue
Do not assume WordPress.com is always cheaper because its transaction fee can be 0%, or that Substack is always cheaper because publishing is free. Compare the fee on your intended plan with your expected paid subscription revenue, payment methods, and any wider site requirements. The available WordPress.com pricing information does not establish a precise break-even point against Substack.
Which platform fits your publishing plans?
Choose Substack for a publication-centered workflow
- Your main goal is to publish writing and offer free or paid subscriptions in an integrated publication environment.
- You do not need a broader website or plugin-based extensions to meet your current needs.
- The 10% platform fee on paid subscription payments, plus processing charges, fits your business model.
Choose WordPress.com for a broader site
- Your publication is one part of a fuller website with other pages or site functions.
- Access to plugin extensions matters; WordPress.com describes a marketplace with more than 60,000 plugins.
- You are willing to compare plans and their transaction fees, which range from 0% to 10% according to WordPress.com.
Compare both before committing
If paid subscriptions, a custom domain, or a possible future move matter to you, check the exact current plan and payment terms. Model costs using the payment mix you expect rather than comparing platform percentages alone.

Substack’s custom-domain setup begins in publication settings; Substack provides a CNAME alias to add with your DNS provider. WordPress.com says its paid plans include a custom domain. Check the current setup instructions and plan terms before choosing based on domain costs.
Both services describe some ways to move audience data. Substack says it supports imports from WordPress and lets writers export data. WordPress.com says a Substack subscriber CSV can be imported, and that content and subscriber lists are exportable. Those capabilities do not guarantee that every post format, setting, or subscriber state will transfer intact. Before switching, verify which content types and subscriber fields your specific migration will preserve.
