Grammarly pricing: what it really costs per year (2026)
Tracker data last verified 2026-08-15. LemDeals is an independent tracker, not the seller.
- Grammarly starts at $12.00/month on its Pro plan — $144 a year, $432 over three years for a single seat.
- That puts it in the 33th percentile of the 24 tool prices we track: 16 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.
- The median lifetime deal we currently track costs $49.99 — the equivalent of 5 months of Grammarly.
- 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 | Cumulative cost (1 seat) | Cumulative cost (5 seats) | Break-even one-time price |
|---|---|---|---|
| 1 year | $144 | $720 | Under $144 |
| 2 years | $288 | $1,440 | Under $288 |
| 3 years | $432 | $2,160 | Under $432 |
| 5 years | $720 | $3,600 | Under $720 |
| 10 years | $1,440 | $7,200 | 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.
What happens when the team grows
Even at a low unit price, seat multiplication is what turns Grammarly into a line item worth reviewing. Assuming linear per-seat pricing on the Pro plan:
| Seats | Monthly | Annual | Three-year total |
|---|---|---|---|
| 1 | $12.00 | $144 | $432 |
| 3 | $36.00 | $432 | $1,296 |
| 5 | $60.00 | $720 | $2,160 |
| 10 | $120.00 | $1,440 | $4,320 |
| 25 | $300.00 | $3,600 | $10,800 |
Where this table will be wrong is at scale: enterprise agreements, education pricing and annual commitments all bend the curve downward. It will not be wrong in the direction of costing you more.
How Grammarly prices against the market
We hold published entry prices for 24 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 33th percentile. The median tracked tool costs $15.00 per month. That places Grammarly in the cheaper half of our priced set, with 16 tracked tools costing more each month.
The tracked tools priced closest to Grammarly are Calendly at $12.00/month, Notion at $12.00/month, Loom at $12.50/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.
What perpetual licences cost right now
Grammarly has never sold a lifetime plan. "Grammarly lifetime" listings are account resales, not licences. These are the cheapest one-time-payment tools our crawler currently observes across the marketplaces we track, each converted into the number of Grammarly months it equals.
| Tracked one-time deal | Category | Marketplace | Lowest observed price | Months of Grammarly it equals |
|---|---|---|---|---|
| Email List Validation | Software | AppSumo | $0.00 | 0 |
| ProductDyno | Software | AppSumo | $0.00 | 0 |
| Shopper.com | Software | AppSumo | $0.00 | 0 |
| Your Cart | Shopping | StackSocial | $0.00 | 0 |

| How to Sell Your Product on AppSumo: The Ultimate Marketing Playbook for Your AppSumo Launch | Courses & learning | AppSumo | $0.00 | 0 |
The conversion column is the point of this table. A perpetual licence is not "cheap" in the abstract — it is a fixed number of subscription months, and it repays only if the tool outlives them.
