Grammarly pricing: what it really costs per year (2026)

TL;DR

• Grammarly starts at $12.00/month on its Pro plan — $144 a year, $432 over three years at the recorded entry rate.
• That puts it in the 41th percentile of the 32 tool prices we track: 19 tracked tools cost more per month, the rest cost less.
• Grammarly is the only writing tool in our priced set, so there is no category median to compare it against yet.
• No tracked lifetime prices were observed this cycle, so there is no break-even comparison to draw.
• Grammarly has a free tier, so for low-volume use the honest comparison is free versus one-time, not subscription versus one-time.

The cumulative bill for Grammarly

The interesting question about a $12.00/month tool is never affordability. It is duration. Grammarly costs $144 for a year and $1,440 if it stays in your stack for a decade, and low-priced tools are the ones that stay longest because nothing ever forces a review. Annual Pro billing is about $12/month.

Time on Grammarly	Baseline cost for one subscription	Break-even one-time price
1 year	$144	Under $144
2 years	$288	Under $288
3 years	$432	Under $432
5 years	$720	Under $720
10 years	$1,440	Under $1,440

The break-even column is a ceiling, not a recommendation. It assumes uninterrupted use across the whole horizon and a perpetual licence that keeps working. Neither assumption is free: churn on your side and vendor shutdown on theirs both destroy the payback.

How Grammarly prices against the market

We hold published entry prices for 32 software tools, which lets us place Grammarly on a distribution instead of calling it affordable or premium with nothing behind the word. Grammarly sits at the 41th percentile. The median tracked tool costs $14.00 per month. That places Grammarly in the cheaper half of our priced set, with 19 tracked tools costing more each month.

The tracked tools priced closest to Grammarly are Calendly at $12.00/month, Notion at $12.00/month, monday.com at $12.00/month. If any of those already sit in your stack, the overlap question comes before the pricing question: two tools at this price point cost $288 a year together, and consolidation is usually the larger saving than any discount on either one.

Grammarly runs its checks server-side, so a permanent licence would commit the vendor to unbounded inference cost. Lifetime writing tools typically use your own model API key to sidestep exactly that problem.

The free tier changes the comparison

Grammarly does not force payment to start, which means the honest framing of the Pro tier is incremental: what does it add over free, and is that increment worth $12.00 every month indefinitely? Name the single limit that would push you to pay, and price that limit. Feature lists are designed to make the upgrade look inevitable; a named constraint makes it a decision.

Try this before upgrading: stay on free for one full month and log each blocked action. A short log means the $432 you would spend over three years buys comfort, not ability.
