Grammarly pricing now sits inside a broader Superhuman product story, which can make an apparently simple subscription choice confusing. The stand-alone writing assistant offers Free, Pro and Enterprise tiers, while the Superhuman suite bundles other tools. A buyer should decide whether they need writing feedback or a broader collection of applications before comparing the headline prices.
Official US plan and support pages checked October 26, 2026 list Grammarly Pro at $12 per member per month when billed annually or $30 per member when billed monthly. A quarterly option is also documented. These figures describe vendor-posted prices, not a customer-specific invoice; region, discounts and tax can change checkout totals.
What the Free tier is designed to do
Grammarly Free covers basic writing corrections and tone visibility, with a limited allowance of generative prompts. On the current public plan page, Free lists 100 AI prompts, while Pro lists 2,000 per member per month. Those allowances are a better way to understand practical use than generic statements about “AI writing,” since high-volume drafting and basic correction are different jobs.
For someone who only wants spelling help in everyday text, start with Free. Test the actual apps and languages used, because a feature displayed on a marketing page may behave differently by device, integration or operating system. Do not treat AI-generated text or plagiarism detection as proof of originality or independent fact checking.
Grammarly Pro: price and included use cases
The official pricing/support pages list Pro at $144 per member for one year, equivalent to $12 per month when prepaid annually. On monthly billing, the support page lists $30 per member. For a single user, those choices total $144 versus $360 across twelve uninterrupted monthly payments at the posted rates, a difference of $216 before tax.
Pro adds full-sentence rewrites, tone changes, enhanced writing suggestions, generative prompt capacity, and features aimed at teams. That does not mean a company can delegate legal review or verify citations automatically. Someone should still check dates, factual claims and sources in high-stakes material, regardless of how polished the sentences appear.
Quarterly billing and choosing the commitment
Grammarly’s official support material also lists a $60 three-month Pro subscription, equivalent to $20 per month over that quarter. Four consecutive quarters at the listed rate would be $240 across a year. These are straightforward nominal comparisons and do not incorporate sales tax, promotions, exchange rates or future plan changes.
Use monthly billing if a short project may end before a year and the higher cash rate is acceptable. Annual billing is financially attractive if sustained use is reasonably certain and upfront payment fits your budget. Estimate the cost of unused months rather than assuming the largest percentage discount is always the right purchase.
Small-team seat math
For a hypothetical five-person writing team, Pro on annual rates is five times $144, or $720 for the year before tax. Five fully active members on monthly rates for an entire year would be five times $360, or $1,800. These figures are arithmetic from the published individual per-member list, not a quotation for a particular corporate contract.
Grammarly states Pro can accommodate multiple seats and that seat additions are prorated. Confirm the seat assignment rules and renewal terms before inviting members. Administrative time, accepted style-rule governance and how people actually use the product can matter more than counting the number of people with accounts.
Enterprise and the wider Superhuman suite
Grammarly Enterprise uses contact-sales pricing and adds negotiated organizational capabilities, including advanced permission and data controls. It is not appropriate to invent an Enterprise price from the Pro seat rate. Ask which products and contractual services are included in the quote, especially because marketing information may also refer to Superhuman Go and bundled applications.
The Superhuman suite publishes its own tiers for Grammarly, Go, Docs and Mail combinations. A $12 suite headline on annual billing does not automatically mean every stand-alone Grammarly add-on or Mail capability is included. Compare the actual entitlement list, cancellation terms, administrator features and data-processing terms before merging two different price pages into one table.
Understand the legacy plan names
Grammarly’s support pages explain that Pro replaced the older Grammarly Business plan. They also discuss Premium subscriptions, including those bought via app stores, and how features or prompt limits differ from Pro. A search result showing a Premium price may describe a different purchase channel or older arrangement, not the currently promoted web Pro checkout.
Existing customers should check their billing portal and renewal notice instead of assuming a newer public price overwrites their current contract. Migration, refunds, promotional trials and tax treatments depend on specific account circumstances. Read the conditions before canceling or replacing a working subscription.
When paying is worth it
Use a concrete threshold. If the free plan handles nearly every task and you rarely need sentence restructuring, paying may not help. If Pro reliably reduces edits across regular English-language customer communications, document the time saved and the types of errors caught. Keep the assessment separate from unverifiable claims that a product makes every writer more persuasive.
For a team, test whether centralized terminology rules and tone guidance actually reduce correction cycles. Count approved messages, measured reviewer effort and retained accuracy. A free writing check plus a shared editorial guide may be the better low-cost answer when an organization has infrequent writing needs or unusually strict security requirements.
A purchase checklist for October 2026
Identify required devices and apps, the number of named members, expected prompts, whether you need shared style guidance and who will administer billing. Then compare monthly, quarterly and annual payments with the likely length of the project. Confirm the current checkout rate in the US or your region and keep a copy of the terms.
Finally, separate “better writing suggestions” from “verified content.” Grammarly can help improve wording, but it cannot transfer responsibility for a customer commitment or a regulatory claim away from the author. For sensitive data, have the organization validate privacy and enterprise terms before onboarding documents or enabling connectors.
How We Research
We cross-checked the official Grammarly plans page, Pro billing support guidance, Premium-to-Pro explanation, and Superhuman suite pricing. Figures refer to posted US rates observed October 26, 2026, before taxes and discounts. Seat calculations are illustrative arithmetic, not checkout tests or account-specific quotes.
