Grammarly Pricing Explained (2026): Every Plan & Cost

Grammarly costs $0 on the free plan and $12/month for Pro if you pay annually — but that same Pro plan is $30/month if you pay month-to-month, a 150% markup for the convenience. Enterprise is custom-quoted. The free tier is genuinely capable, so the real decision is whether Pro's AI features earn the upgrade. Here's every plan and the traps to avoid.

Every plan & price

Plan	Price	Best for
Free	$0	Grammar, spelling, basic tone, 100 AI prompts/month
Pro (annual)	$12/mo ($144/yr)	Individuals who use rewrites and generative AI weekly
Pro (quarterly)	$20/mo	Short commitments, still cheaper than monthly
Pro (monthly)	$30/mo	Testing only — the most expensive way to pay
Enterprise	Custom	Organizations needing SSO, SCIM, and admin controls

The free plan

Grammarly's free tier is one of the better free plans in software. It covers grammar, spelling, punctuation, and basic tone detection across every app the extension supports, with no payment details or seat minimum required. It also includes 100 AI prompts per month for generative writing and rewrites.

For most people who just want cleaner emails and documents, this is enough — you may never need to pay. The free plan is the reason we tell readers to install Grammarly before deciding whether Pro is worth it.

Pro, and the billing trap

Pro unlocks unlimited rewrites, the full generative AI, a style guide, brand tone, snippets, and team analytics — plus light team features like up to two user groups. The features are worth it if you use them, but how you pay matters more than most tools: annual is $12/mo, quarterly is $20/mo, and monthly is $30/mo.

That means month-to-month costs 2.5× the annual rate. The trap is signing up monthly "just to try it" and forgetting to switch — you'd pay $360 a year instead of $144. Use the free plan to test, then commit annually once you know you want it.

Enterprise

Enterprise is quote-only and aimed at larger organizations. On top of everything in Pro it layers the security and administration features IT teams require: SAML single sign-on, SCIM provisioning, managed mode, BYOK encryption, data loss prevention, custom roles, an Audit Logs API, and dedicated support. If you're a solo user or small team, you'll never need it; if you're rolling Grammarly out to hundreds of employees under a compliance policy, this is the tier your IT department will want.

Is it worth it?

Free is worth it for everyone — install it, no question. Pro is worth it if you rewrite for tone, generate drafts and replies, or maintain a consistent style across a team, and you pay annually at $12/mo. That's cheaper than most AI subscriptions and it works in every app, which is hard to beat for the money.

Pro isn't worth it if you only need grammar and spelling — the free plan already does that — or if your real need is drafting long-form content, where a dedicated tool like Jasper or Copy.ai is a better spend.
