Grammarly simplified its pricing in 2025 — killing the old Premium and Business tiers and replacing them with Free, Pro, and Enterprise. Simpler, but the AI prompt limits and per-seat costs still need explaining. Here’s what each plan actually includes and what the real annual cost looks like.

Grammarly Pricing at a Glance
| Plan | Monthly | Quarterly | Annual | Best for |
|---|---|---|---|---|
| Free | $0 | $0 | $0 | Basic grammar/spelling |
| Pro | $30/mo | $20/mo | $12/mo | Individuals and teams (1-149 seats) |
| Enterprise | Custom (150+ seats) | Large organizations | ||
Three tiers. Clean. But the gap between $12/month (annual) and $30/month (monthly) is 150% — one of the largest billing period penalties in SaaS.
Free: Better Than Nothing, Worse Than You’d Hope
Grammarly Free does catch basic errors. For casual email writers, it’s fine.
- Basic grammar, spelling, and punctuation corrections
- Tone detection
- 100 AI prompts per month
- Works in Chrome, Edge, Word, Gmail, etc.
What Free misses: clarity rewrites, vocabulary suggestions, tone adjustments, plagiarism detection, and the full AI writing assistant. The 100 AI prompts sound decent until you realize each “rewrite this paragraph” or “make this more formal” counts as one prompt. Heavy users burn through 100 in a few days.
Pro ($12-30/mo): Everything in One Plan
Grammarly consolidated Premium and Business into a single “Pro” tier. Whether you’re one person or a 149-person team, it’s the same plan.
- Everything in Free
- Full-sentence rewrites for clarity and conciseness
- Vocabulary enhancement suggestions
- Tone adjustments — shift writing between formal, casual, confident, etc.
- Plagiarism detection (checks against 16B+ web pages)
- 2,000 AI prompts/month — 20x more than Free
- Brand tones and style guides — define how your team should write
- Snippets — reusable text templates for common responses
- Analytics dashboard (for teams)
- Admin controls and team management (multi-seat)
The pricing varies dramatically by billing period:
$144 vs $360 /year
Annual: $12/mo × 12 = $144/year
Quarterly: $20/mo × 12 = $240/year
Monthly: $30/mo × 12 = $360/year
Annual billing saves you $216/year over monthly. That’s 60% savings.
The annual commitment is a no-brainer if you plan to use Grammarly for more than 5 months. Even quarterly billing saves $120/year over monthly.
Pro for Teams: Same Plan, Per-Seat Pricing
Grammarly Pro works for teams of up to 149 seats. Each seat gets the full Pro feature set.
| Team size | Annual cost (per seat) | Total annual |
|---|---|---|
| 1 person | $144/yr ($12/mo) | $144 |
| 5 people | $144/yr each | $720 |
| 10 people | $144/yr each | $1,440 |
| 25 people | $144/yr each | $3,600 |
| 50 people | $144/yr each | $7,200 |
No volume discounts below 150 seats. A 50-person team pays the same per-seat rate as a solo user. If you’re at 100+ seats, start a conversation with Grammarly’s sales team about Enterprise pricing — you might get a better deal.
Enterprise: Custom Everything
Enterprise is for organizations with 150+ users. Pricing isn’t public, but you get:
- Everything in Pro
- SAML SSO
- Advanced admin controls and analytics
- Security and compliance features (SOC 2, HIPAA-eligible)
- Custom AI prompt limits
- Dedicated customer success manager
- Data governance and retention policies
- Priority support
Based on vendor data, Enterprise pricing typically ranges from $15-25/seat/month depending on volume and contract terms. At scale, this can actually be cheaper than Pro’s $12/seat when bundled with other features.
The AI Prompt Limit: Will You Hit It?
Grammarly’s generative AI features use a prompt-based system:
| Plan | AI prompts/month | What counts as a prompt |
|---|---|---|
| Free | 100 | Each AI-powered rewrite, suggestion, or generation |
| Pro | 2,000 | Same actions, 20x more |
| Enterprise | Custom | Negotiable |
2,000 prompts/month is generous for most users. If you write 10 emails a day and use AI assistance on each, that’s ~300 prompts/month. You’d need to write heavily and use AI rewrites on virtually everything to hit 2,000.
But for teams sharing a pool of prompts? It depends on how many heavy writers you have. A 25-person team with 5 heavy AI users could potentially feel the cap.
Grammarly vs the Competition
| Tool | Price (annual) | AI writing? | Key difference |
|---|---|---|---|
| Grammarly Pro | $12/mo | Yes (2,000 prompts) | Best all-around writing assistant |
| ProWritingAid | $10/mo | Limited | Deeper style analysis, cheaper |
| Hemingway Editor | $10 one-time | No | Simplicity-focused, no subscription |
| ChatGPT Plus | $20/mo | Full AI writing | More powerful AI, no grammar checking |
Hidden Costs and Gotchas
The billing period trap
$30/month vs $12/month is the same product. The only difference is your commitment. Grammarly bets most monthly users will forget to cancel. If you’re going to use it, commit to annual.
No volume discounts under 150 seats
Seat #1 costs the same as seat #149. No loyalty pricing, no bulk discount. This is unusual in SaaS — most tools offer tiered pricing above 10-25 seats.
Plagiarism checks are limited
Plagiarism detection is included with Pro, but heavy academic use may hit undisclosed limits. Grammarly isn’t a replacement for Turnitin if you’re checking dozens of papers daily.
Browser extension data
Grammarly’s browser extension processes your text on their servers. For privacy-sensitive content (legal, healthcare, financial), consider whether this is acceptable for your compliance requirements.
Who Should Pick What
Occasional writer: Free. The basic grammar and spelling corrections catch most errors.
Daily writer (emails, docs, content): Pro annual ($12/mo). The clarity rewrites and AI prompts are genuinely useful. The annual plan is the only pricing that makes sense.
Teams (5-50): Pro for teams. Same price per seat as individual, but you get admin controls, brand tones, and shared style guides.
Large org (150+): Enterprise. Negotiate for volume pricing and SSO.
Frequently Asked Questions
Is Grammarly Free good enough?
For catching typos and basic grammar, yes. For improving writing quality (clarity, tone, vocabulary), no. The paid features make a noticeable difference in writing quality.
Is Grammarly Pro worth $12/month?
If you write professionally — emails, reports, content, client communications — yes. The time saved on editing and the quality improvement easily justify $144/year. If you write a few emails a week, Free is probably enough.
What happened to Grammarly Premium and Business?
Grammarly consolidated them into a single “Pro” tier in 2025. Pro includes everything from both old plans. Simpler pricing, same features.
Does Grammarly work with Google Docs?
Yes. Grammarly integrates with Google Docs, Microsoft Word, Gmail, Outlook, Slack, and most text fields via browser extension. It also has desktop apps for Mac and Windows.
Can Grammarly detect AI-generated text?
Grammarly has an AI text detection feature, but it’s separate from the writing assistant. Detection accuracy varies — don’t rely on it as your sole AI content checker.
