Grammarly Pricing 2026: Free, Pro & Enterprise Costs

Grammarly pricing is unusually straightforward for an AI writing product. Free costs nothing, Pro has three published billing cadences, and Enterprise is custom-priced for organizations that need broader governance.

The headline pricing choice is mostly about commitment. The exact same Pro plan can cost $30 per member on monthly billing or the equivalent of $12 per month when paid annually. That 60% gap makes annual billing compelling for committed users but expensive to reverse because Grammarly's general refund policy is restrictive.

Grammarly pricing at a glance

Free: $0

Grammarly Free includes the core writing experience: grammar, spelling and punctuation assistance, tone visibility and limited generative AI.

Current support documentation lists 100 generative AI prompts per month.

Free is enough for users who want mistake detection and occasional AI help but do not need full-sentence rewrites, advanced tone adjustment, team brand controls or high AI usage.

Pro monthly: $30/member/month

Monthly Pro is the most flexible paid option and the most expensive per month. It costs $30 per member with no longer billing commitment.

The plan includes advanced writing features, full-sentence rewrites, tone adjustment, brand tools and 2,000 monthly AI prompts.

Monthly billing makes sense for short projects, temporary teams or buyers who want flexibility after the trial. Long-term users pay a large premium for that flexibility.

Pro quarterly: $60/member/three months

Quarterly billing costs $60 per member every three months, equivalent to $20 per month.

This is a middle ground between the $30 monthly rate and $12 annual-equivalent rate.

For users who are not ready to commit for a year but expect to use Grammarly for several months, quarterly pricing saves $30 over three months compared with monthly billing.

Pro annual: $144/member/year

Annual Pro costs $144 per member per year, equivalent to $12 per month.

Twelve months of monthly billing would cost $360, so annual billing saves $216 per member over a full year, or 60% compared with paying monthly.

The discount is substantial enough that users should decide based on expected duration, not only the convenience of monthly payment.

What Pro includes

Pro includes everything in Free plus full-sentence rewrites, tone adjustment, advanced suggestions, plagiarism and AI-detection access in supported workflows, 2,000 monthly generative AI prompts and team functionality.

For teams, Pro also includes features such as style guides, brand tones, knowledge share, snippets and usage analytics.

These collaboration features make Pro relevant to small and midsize teams, not only individuals.

Pro seat limit

Grammarly Pro supports up to 149 seats under the current web-purchased plan.

Additional seats use the same selected billing cadence and are prorated based on the remaining days in the subscription period.

A team should therefore model annual cost as $144 multiplied by active seats, while also accounting for seats added mid-term.

Enterprise: custom pricing

Enterprise is designed for larger organizations and is now sold through the broader Superhuman environment.

Current plan materials list unlimited members, dedicated support, confidential mode, granular roles and permissions, data loss prevention and unlimited generative AI prompts.

Because numerical Enterprise pricing is not public, buyers should request seat, platform and bundle details from sales.

Enterprise versus Pro

The main reason to move beyond Pro is governance rather than writing quality alone.

Pro already supports up to 149 members and gives teams style guides and brand controls. Enterprise becomes relevant when security teams need confidential-mode enforcement, DLP, unlimited membership, granular permissions and more advanced administrative requirements.

Organizations should compare the cost of Enterprise with the operational risk it reduces rather than expecting dramatically different grammar suggestions.

Seven-day free trial

Grammarly currently offers a seven-day free trial for eligible paid subscriptions.

A payment method may be verified during signup. Grammarly says a pending verification charge can appear temporarily but should not become the actual subscription charge if the trial is canceled properly.

Canceling a free trial ends paid access immediately and converts the account to Free.

How to cancel the trial

Users can cancel from Account → Subscription. Grammarly requires the user to confirm cancellation and select a reason.

Because trial access ends immediately, someone who wants to test all seven days should schedule cancellation carefully rather than canceling immediately after signup.

AI prompt limits

Current Grammarly support documentation lists 100 monthly prompts for Free and 2,000 for Pro.

Legacy/mobile Grammarly Premium includes 1,000 monthly prompts. Current web-purchased Pro doubles that allowance and adds team features.

Enterprise materials advertise unlimited generative AI prompts.

What happens if Pro runs out of prompts?

When the monthly allowance is exhausted, generative AI stops until prompts refill. Grammarly currently advises paid users who run out early to contact support.

There is no standard public self-serve overage price per prompt on Pro.

This makes Pro simpler than token-based billing but less flexible for a user who needs a temporary burst above 2,000 prompts.

Prompt refill timing

Grammarly says prompts automatically refill monthly based on the date generative AI first became available for the account.

The reset therefore may not match the first day of the calendar month.

Teams should avoid assuming every member resets on the same date unless their account configuration confirms it.

Premium versus Pro

Grammarly Premium still exists through the App Store and Google Play. It is designed for individuals and includes core paid writing features with 1,000 monthly generative AI prompts.

Web-purchased Grammarly Pro includes 2,000 prompts and team features for up to 149 seats.

Buyers should therefore distinguish mobile-store Premium from current web Pro when comparing screenshots or older reviews.

Additional seat pricing

Additional Pro seats follow the selected billing cadence: $30 monthly, $60 quarterly or $144 annually per member.

Seats added during the term are prorated for the remaining subscription period.

For a growing team, annual seat cost remains transparent, but administrators should remove unnecessary seats before renewal if they no longer need access.

Taxes and regional pricing

Grammarly says the default currency is USD but supports regional pricing in euros, British pounds and Indian rupees, with the actual currency/rate shown at checkout.

Taxes can apply based on location and business status.

SearchSagar uses US-dollar list pricing for consistency; the user's actual checkout can differ.

Payment methods

Grammarly supports major credit/debit cards along with PayPal, Apple Pay and Google Pay where available.

Specific payment methods can vary by processor or region.

Refund policy

Grammarly says paid subscriptions can be canceled at any time, but refunds are issued only when required by law.

App Store purchases use Apple's refund process.

This means the annual discount should be treated as a real commitment. A user should not assume Grammarly offers a general 30-day money-back guarantee.

Cancellation policy

Canceling a paid subscription stops automatic renewal. Paid features remain available for the rest of the current paid term.

This differs from canceling a free trial, which ends trial access immediately.

Current Superhuman support also notes that canceling through an associated Grammarly account can apply across linked Superhuman-suite applications, so bundled users should review the impact before canceling.

Annual savings calculation

Monthly billing for one year costs $360 per member. Quarterly billing for four quarters costs $240. Annual billing costs $144.

That means annual saves $216 compared with monthly and $96 compared with quarterly.

For 10 users, annual Pro costs $1,440/year before tax compared with $3,600 if those seats remain monthly for a full year.

Cost scenario: solo professional

A solo writer who expects to use Grammarly all year has the strongest economic case for annual Pro.

A freelancer with a three-month client project may prefer quarterly billing even though the unit price is higher.

Someone who mainly wants spelling and grammar correction should start on Free and upgrade only when advanced rewriting or AI limits become a real constraint.

Cost scenario: 20-person team

Twenty annual Pro seats cost $2,880 per year before taxes.

The same seats on monthly billing for a full year would cost $7,200.

At this scale, teams should also compare Enterprise if confidential mode, DLP, SSO, unlimited prompts or governance requirements have operational value.

When annual Pro breaks even

Annual Pro costs $144. At the $30 monthly rate, a user reaches $150 after five months. That means anyone expecting to keep Pro for five months or longer pays less with the annual plan than by staying monthly for the same period.

Quarterly billing costs $60 every three months. Two quarters cost $120, while three quarters cost $180. Annual becomes cheaper than quarterly once usage extends beyond roughly seven months.

The tradeoff is refund flexibility. Because Grammarly generally does not refund unused subscription time except where law requires it, the lower annual price should be chosen only after the seven-day trial confirms the workflow fit.

Prompt economics

Pro's 2,000 monthly prompts equal roughly 66 prompts per day in a 30-day month if usage is evenly distributed. Most users will not need that many generative actions if Grammarly is primarily used for grammar and rewriting.

Heavy generative-AI users should track whether they approach the limit. Grammarly does not publish a standard per-prompt overage rate, so a user cannot simply buy 500 extra prompts the way some credit-based AI products allow.

This makes Enterprise's unlimited generative AI allowance more relevant for organizations that want employees to use Go/Grammarly agents intensively without individual prompt ceilings.

50-seat and 100-seat annual examples

At published annual Pro pricing, 50 seats cost $7,200 per year before tax and 100 seats cost $14,400. The same seats kept on monthly billing for a full year would cost $18,000 and $36,000 respectively.

At those team sizes, the commercial decision is no longer only about discount. Buyers should compare Enterprise governance, DLP, confidential mode, SSO and unlimited AI usage against the operational risk and administration burden of self-serve Pro.

Pricing versus ChatGPT

ChatGPT Plus costs $20 per month, while Grammarly Pro is $30 monthly but only $12 annual-equivalent. ChatGPT is broader for research, coding and open-ended generation; Grammarly is more specialized as an inline communication layer.

A writing-heavy professional may use both because they solve different parts of the workflow.

Pricing versus Jasper

Jasper Pro currently costs $69 per month or $59 per month billed annually and includes one seat, Canvas, marketing Agents and brand customization. Business is custom-priced.

Jasper costs more than Grammarly because it is positioned as a marketing content platform rather than primarily an editing assistant.

Pricing versus Writesonic

Writesonic's current positioning is AI search visibility plus content/SEO. Starter is $79 per month billed annually and Basic $199 per month billed annually under the current brand pricing surface.

That makes it a very different purchase from Grammarly. Teams should only compare Writesonic if SEO/GEO content production is part of the requirement.

Final pricing verdict

Grammarly has one of the clearest pricing models in AI writing. The decision is mostly whether advanced features justify Pro and which billing cadence matches expected usage duration.

Annual Pro is by far the strongest value for committed users. Monthly billing is useful for flexibility, while Enterprise should be evaluated for governance rather than basic writing quality alone.
