Grammarly is everywhere — browser extensions, Google Docs, Microsoft Word, desktop apps, and now your IDE. But with three distinct tiers, a restructured AI writing layer, and per-seat Business pricing that scales quickly, figuring out what you actually need to pay for takes more than a glance at the pricing page.
This breakdown covers every Grammarly plan for 2026: what’s included, what’s locked away, how the math works for teams, and whether the upgrade from Free is actually worth it for your specific use case.

Grammarly Plan Overview: Quick Summary
Free | $0/month | Basic grammar, spelling, punctuation checks; limited GrammarlyGO AI prompts; browser extension; works in 500,000+ apps
Premium | $12/month (annual) or $30/month (monthly) | Everything in Free + advanced suggestions, clarity rewrites, tone detection, plagiarism checker, full GrammarlyGO AI access
Business | $15/seat/month (annual, 3-seat minimum) | Everything in Premium + style guides, brand tone settings, admin dashboard, team analytics, priority support, SAML SSO
All plans include the core Grammarly editor, browser extension for Chrome/Firefox/Safari/Edge, and desktop apps for macOS and Windows. The differences are in suggestion depth, AI generation limits, and team management tools.
Grammarly Free: What You Actually Get
The free plan is more functional than most “freemium” tiers in this category. It catches real errors — not just obvious typos but subject-verb disagreement, comma splices, and basic punctuation issues. For someone writing casual emails or social posts, it gets the job done.
Free Plan Inclusions
- Grammar, spelling, and punctuation corrections
- Basic sentence structure suggestions
- Tone detection (limited — shows “formal,” “neutral,” “informal”)
- GrammarlyGO: 100 AI prompts per month (rewrite, generate, improve)
- Works across 500,000+ apps via browser extension
- Mobile keyboard for iOS and Android
- Grammarly desktop editor
What Free Doesn’t Cover
- Clarity and conciseness suggestions (flagging wordy sentences)
- Advanced vocabulary and word choice improvements
- Plagiarism checker (no access at any level below Premium)
- Full tone detection breakdown and rewrite suggestions
- GrammarlyGO beyond 100 monthly prompts
- Style guides (Business only)
The 100 AI prompt limit on Free resets monthly. For a light user editing a few emails per week, that’s enough. For anyone producing regular long-form content, you’ll hit the ceiling within days.
Grammarly Premium: Pricing and What Changes
Premium Pricing
| Billing Cycle | Monthly Cost | Annual Total |
|---|---|---|
| Monthly | $30/month | $360/year |
| Annual (billed yearly) | $12/month | $144/year |
| Quarterly | $20/month | ~$240/year |
The annual plan is by far the best value — $12/month compared to $30/month on monthly billing is a 60% discount. If you try it monthly and decide to stick with it, switching to annual at renewal saves you $216 per year.
Student discount: Grammarly offers discounted Premium pricing for verified students. Exact pricing varies by region and academic institution, but discounts typically reach 20–40% off standard annual rates. Check Grammarly’s student page with a .edu or institution email.
What Premium Adds Over Free
- Clarity rewrites: Grammarly flags overly complex sentences and offers simplified alternatives — not just pointing out an issue, but showing you a better version
- Vocabulary suggestions: Word choice upgrades based on context, not just synonym swaps
- Full tone detection: More granular breakdown (confident, diplomatic, accusatory, etc.) with rewrite options to shift tone in a specific direction
- Plagiarism checker: Compares your text against 16 billion web pages; shows percentage match and sources
- Fluency suggestions: Particularly useful for non-native English speakers — catches unnatural phrasing that’s technically grammatically correct
- GrammarlyGO full access: Unlimited AI prompts for rewrites, tone shifts, length adjustments, and freeform generation
- Formatting suggestions: Flags inconsistent punctuation, hyphen use, list formatting
GrammarlyGO on Premium
GrammarlyGO is Grammarly’s AI writing assistant, built on top of large language models with Grammarly’s own writing rules layered over the output. On Premium, you get unlimited prompts. The practical use cases:
- Rewriting a paragraph to be more direct or more formal
- Generating a first draft from bullet points
- Adjusting email tone before sending
- Summarizing long documents
- Expanding a short note into a full section
The output quality is solid for business writing — better than generic ChatGPT output for professional tone because it’s calibrated toward clear, correct English rather than conversational output. It’s not a replacement for a writer, but it’s a fast starting point.
Grammarly Business: Pricing and Team Features
Business Pricing
| Seats | Cost Per Seat/Month (Annual) | Monthly Total | Annual Total |
|---|---|---|---|
| 3 seats (minimum) | $15/seat | $45/month | $540/year |
| 10 seats | $15/seat | $150/month | $1,800/year |
| 25 seats | $15/seat | $375/month | $4,500/year |
| 50+ seats | Custom (contact sales) | — | — |
There is no published flat rate for teams above 50 seats — Grammarly moves to negotiated enterprise pricing with custom contracts. For teams between 3–49 seats, the $15/seat/month rate applies consistently.
Compare that to Premium: if you have a 3-person team each buying Premium annual, you’re paying $36/month total ($12 × 3) vs. $45/month for Business. The $9/month difference buys you style guides, admin controls, and centralized billing. For most teams, that’s worth it. For solo freelancers, it’s not.
What Business Adds Over Premium
Style Guides
This is the flagship Business feature. Style guides let admins set organization-specific writing rules: preferred terminology, banned words, formatting standards, and brand voice guidelines. Every team member’s Grammarly instance enforces these rules in real time.
Practical example: a SaaS company can add a style guide rule that flags “utilize” and suggests “use,” bans the term “solution” in customer-facing copy, and enforces Oxford comma usage. Writers see these as suggestions inline — the same way Grammarly’s core grammar checks appear.
Brand Tones
Beyond individual tone detection, Business lets admins define approved tone profiles. GrammarlyGO on Business accounts can generate content that matches the defined brand voice rather than defaulting to generic professional English.
Admin Dashboard
- Centralized seat management (add/remove users)
- Usage analytics by team member
- Consolidated billing with invoice support
- Permission controls for style guide editing
SAML Single Sign-On (SSO)
Enterprise-standard authentication via your existing identity provider (Okta, Azure AD, Google Workspace, etc.). Required by most IT security policies at mid-size companies. Not available on Premium.
Priority Support
Business accounts get priority routing in the support queue. For a team-critical writing tool, faster resolution on account issues matters.
Snippets
Shared text snippets that the whole team can access — pre-written email openers, standard disclaimers, common response templates. Triggered by shortcuts in any text field where Grammarly runs.

Grammarly vs. ProWritingAid vs. Hemingway: Pricing Snapshot
If you’re evaluating Grammarly against alternatives, here’s how the pricing stacks up for individual users:
| Tool | Free Tier | Paid (Annual) | Lifetime Option |
|---|---|---|---|
| Grammarly Premium | Yes (limited) | $12/month | No |
| ProWritingAid Premium | Yes (limited) | $10/month (~$120/year) | Yes (~$399 one-time) |
| Hemingway Editor | Free web version | N/A | $19.99 desktop app |
ProWritingAid is cheaper per year and has a one-time lifetime option — a genuine advantage for long-term individual users. But Grammarly’s real-time inline suggestions across every app (not just a standalone editor) is a practical workflow advantage that ProWritingAid hasn’t fully matched. Hemingway is a different category entirely: it’s a readability tool that flags passive voice and adverbs, not a grammar checker.
For teams, the comparison shifts further toward Grammarly — ProWritingAid Teams pricing is competitive, but Grammarly’s app coverage and style guide feature are stronger for organizations with mixed writing environments.
Who Should Stay on Free
- Casual email writers and social media users who don’t produce regular long-form content
- Students who only need occasional help with basic errors (and don’t need plagiarism checking)
- Anyone testing Grammarly before committing to a paid plan
- Non-native English speakers doing personal writing where perfect fluency isn’t required
Who Should Upgrade to Premium
- Freelance writers, copywriters, and content marketers producing regular written output
- Professionals writing client-facing or executive communications (proposals, reports, presentations)
- Non-native English speakers who need fluency suggestions beyond basic grammar
- Anyone submitting academic work where plagiarism verification matters
- Remote workers who need AI writing assistance without switching tools
The annual plan at $12/month is the right choice if you’re writing more than a few hundred words per week professionally. Monthly billing at $30 is hard to justify unless you need it for a single project.
Who Needs Business
- Content and marketing teams that need consistent brand voice across writers
- Companies with IT security requirements (SSO, centralized credential management)
- Agencies managing multiple clients with different style standards
- Organizations where billing consolidation and usage visibility matter to finance or IT
- Any team of 3+ where individual Premium subscriptions would require manual reimbursement
The $3/seat/month premium over Premium is justified almost entirely by style guides and admin controls. If neither of those matter to your team, individual Premium subscriptions are cheaper.
Free: Adequate for casual use. Hits a real ceiling fast for anyone writing professionally.
Premium Annual ($12/month): Best value for individual professionals. The plagiarism checker and unlimited GrammarlyGO alone justify the cost for anyone publishing content regularly.
Business ($15/seat/month): Worth the premium specifically for style guides and SSO. For small teams without those needs, individual Premium accounts save money.
Monthly Premium ($30/month): Only makes sense for short-term project-based use. Switch to annual if you’re staying more than 2 months.
How to Get the Best Price
- Annual billing always: The gap between monthly ($30) and annual ($12) Premium is one of the largest in any SaaS product. Never pay monthly if you plan to use it long-term.
- Student discount: Verify with a school email before buying. Discounts are real and substantial.
- Black Friday deals: Grammarly typically runs 40–55% off Premium annual subscriptions in November. If you’re on the fence, waiting for that window can cut the annual cost under $90.
- Business vs. individual Premium: Run the math. For 3 people: Business = $540/year vs. Premium × 3 = $432/year. The $108 difference buys you style guides and admin controls — price them accordingly for your team.
Bottom Line
Grammarly’s pricing structure is actually fairly honest: Free is usable but limited, Premium is a real upgrade with a real annual discount, and Business adds team management features that either matter to your organization or they don’t.
The decision point for most people is Premium vs. Free. If you write professionally — anything customer-facing, published, or submitted for evaluation — $144/year for Premium annual is a defensible expense. The clarity suggestions and plagiarism checker alone justify it for content writers. GrammarlyGO’s unlimited AI prompts make it more valuable still as AI-assisted writing becomes standard practice in 2026.
For teams, the question is whether style guides and SSO are worth $3 more per seat per month than individual Premium accounts. For most content and marketing teams, yes. For small teams without brand voice requirements, probably not.
