Is Grammarly Worth It?
Grammarly Free is sufficient for most casual writers. Premium at $12/mo is worth it for professionals who write daily — the plagiarism detection, full-sentence rewrites, and 1,000 AI prompts pay for themselves if you spend 30+ minutes per day writing emails, documents, or content. Business at $15/mo per member is a no-brainer for teams that need brand consistency.
Annual vs Monthly Billing
Premium is $12/mo on annual billing ($144/year) vs $30/mo on monthly billing — a 60% savings. The free plan has no time limit and is generous enough to evaluate whether the Premium features are worth the upgrade for your workflow.

Cost Per Unit
At $12/mo on Premium, Grammarly costs roughly $0.40/day. If it catches one embarrassing email mistake per week or saves 10 minutes of proofreading per day, the ROI is immediate. A professional editor charges $30-60/hour — Grammarly provides continuous editing for a fraction of a single editing hour.
How Grammarly Pricing Compares
Grammarly Premium ($12/mo) is cheaper than ProWritingAid Premium ($10/mo annual) but more expensive than its free tier. Hemingway Editor is a one-time $19.99 purchase but lacks real-time integration. ChatGPT Plus ($20/mo) can proofread but does not integrate into your browser, email, and docs the way Grammarly does.
