Grammarly’s pricing structure is simpler than it looks, but the “Business plan” situation is a bit of a mess right now and worth explaining. Let me break it all down.
Grammarly Plans at a Glance (July 2026)
| Plan | Monthly Cost | Annual Cost | Best For |
|---|---|---|---|
| Free | $0 | $0 | Casual users, students, basic editing |
| Pro (annual billing) | $12/month | $144/year | Writers, professionals, frequent users |
| Pro (monthly billing) | $30/month | $360/year | Short-term users, testing Pro |
| Pro (quarterly billing) | $20/month | $240/year | Middle ground option |
| Enterprise | Custom | Custom | Organizations, teams, compliance needs |
The Free Plan: What You Actually Get
Grammarly Free is legitimately useful. It’s not a crippled demo.
You get real-time grammar and spelling checking that works across the web — Chrome extension, Google Docs integration, email, social media. The fundamental error-catching (typos, punctuation mistakes, subject-verb agreement) is available in the free tier and works well.
What’s included in Free:
- Grammar and spelling corrections
- Basic punctuation and sentence structure fixes
- 100 AI prompts per month (for rewrites and suggestions)
- Browser extension, desktop app, and Google Docs add-on
- Tone detection (basic)
What’s not included:
- Advanced clarity and engagement suggestions
- Delivery adjustments (formality, confidence level)
- Full plagiarism checker
- Style suggestions
- More than 100 AI-assisted prompts per month
The 100 AI prompts limit is the practical ceiling of the free tier. If you’re using Grammarly’s AI rewrite features heavily, you’ll hit this. If you mostly use it as a grammar checker, 100 prompts/month is probably enough.
Pro Plan: What You’re Actually Paying For
Pro costs $12/month on annual billing. That’s $144 upfront. Monthly billing is $30 — if you’re planning to use Grammarly for more than 5 months, annual is dramatically cheaper.
The upgrade from Free to Pro is about writing quality, not just error volume. Grammarly Free catches mistakes. Grammarly Pro catches mistakes and makes your writing better.
Advanced suggestions in Pro analyze your writing for clarity, engagement, and persuasiveness. Instead of just flagging a grammar error, Pro might flag a sentence as unclear and suggest a rewrite that actually communicates your point more effectively.
Tone adjustments in Pro are more granular. You can set a target formality level or adjust for specific communication contexts — more confident, more diplomatic, more concise. This is genuinely useful if you write across different contexts (internal Slack messages vs. client emails vs. public content).
Plagiarism checking in Pro compares your text against billions of web pages. If you’re writing content that needs to be original — blog posts, academic work, business reports — this is a real feature, not a marketing checkbox. It finds unintentional similarity to existing web content.
Up to 1,000 AI prompts/month vs. 100 in Free. For writers using Grammarly’s AI features regularly, this is a meaningful difference.
Is Pro worth it? Depends on the use case.
If writing is central to your work — content marketing, copywriting, communications, journalism — Pro pays for itself. The quality improvements are real and the time savings on revision are real.
If you write occasional emails and simple documents, Free is probably enough. The difference between a Free-corrected email and a Pro-corrected email is real but not dramatic enough to justify $144/year for a casual user.
The Business/Enterprise Situation
This is where Grammarly’s pricing gets confusing.
Grammarly previously offered a Business plan at $15/user/month (billed annually) for teams of 3 or more. That plan included centralized billing, admin controls, usage analytics, and brand tone guidelines.
In 2025-2026, Grammarly has been transitioning team accounts toward their Enterprise tier, which has custom pricing based on team size, features, and contract terms. The old Business plan pricing isn’t consistently advertised anymore.
What this means for you:
- Individual users: Pro pricing above is current and accurate
- Teams and organizations: Contact Grammarly Sales (grammarly.com/enterprise) for current team pricing
- Existing Business plan customers: You likely have grandfathered pricing until your contract renews
Enterprise adds: SSO and SAML authentication, admin dashboards, style guide enforcement at the organization level, API access, dedicated support, and compliance features. For organizations writing at scale or with brand consistency requirements, these features are worth the conversation.
How Grammarly Compares to Its Alternatives
vs. Microsoft Editor (free with Microsoft 365): If you’re already paying for Microsoft 365, Editor covers the basics for free. It’s less capable than Grammarly Pro on advanced suggestions, but for MS Word and Outlook users, it’s a reasonable default.
vs. ProWritingAid: ProWritingAid’s annual plan runs around $70/year — cheaper than Grammarly Pro at $144/year. ProWritingAid goes deeper on writing style analysis but is heavier and slower. Grammarly wins on speed, browser integration, and ease of use. ProWritingAid wins on depth of feedback for manuscript-length writing.
vs. Hemingway App: Hemingway is a one-time purchase (~$20) with no subscription. It focuses on readability and sentence simplification, not grammar checking. Different tool entirely — use Hemingway to simplify writing, Grammarly to check and improve it.
Getting the Best Price
Annual billing is almost always right. $12/month annually vs. $30/month monthly. If you know you’ll use Grammarly for more than 5 months, annual saves you money immediately.
Student discount. Grammarly offers a student discount — check grammarly.com/student for current offers. It’s typically 20% off Pro.
Black Friday/Cyber Monday. Grammarly runs significant discounts in November — typically 40-60% off Pro annual subscriptions. If you’re not in a hurry, waiting for their November promotion gets you the best price of the year.
The Verdict
Grammarly Free is a good product that’s actually free. Use it if you write occasionally or just need a grammar safety net.
Grammarly Pro at $12/month (annual) is worth it if writing is part of your job. The improvement in suggestion quality is real, the plagiarism checker has genuine utility, and the AI prompt limits in Free become annoying quickly for active users.
The Enterprise/team situation is opaque right now. If you’re evaluating Grammarly for your team, contact sales rather than trying to reverse-engineer what pricing applies.
