Grammarly pricing table
Compare meters side by side before opening each calculator. Watch the unit carefully: a “cheap” host rate is not comparable to a per-GB or per-million-events rate. The source column links to the official page used for verification.

Grammarly services and APIs in this catalog
Each table row maps to a full service page: volume calculator, cost profile (what 1, 1k, and 1M units cost, and how far $100 goes), and the pricing documentation link. If Grammarly publishes included quotas on monthly plans, use the calculator for the variable part and read the inclusion on the official source.
For engineering and finops teams, the practical flow is: (1) list the meters your product actually hits, (2) fill real or peak volume, (3) sum the results instead of guessing a single “platform average.” Large platforms mix several counters—logs, APM, infrastructure, RUM—and budget misses start when every line is treated as the same meter.

Frequently asked questions about Grammarly
What does Grammarly bill for usage in this catalog?
There are 2 published meters for Grammarly, billed in units such as Pro member-month (annual), Pro member-month (monthly billing). Each page shows the list unit price, the billing unit, and the date the figure was checked against the public source.
Which Grammarly meter has the lowest unit price here?
Grammarly Pro member seat (annual) lists $12.00 per Pro member-month (annual). Use that page’s calculator to project daily and monthly volume before you lock a budget.
Do Grammarly monthly plans roll into the calculator figure?
When the source publishes a per-unit rate (per GB, per request, per seat, and so on), the calculator uses that linear list rate. Included quotas, monthly minimums, annual packs, and volume discounts still need to be read on the official docs—CostUse keeps the source and verification date visible on every service page.
How should I compare Grammarly services against each other?
Use the pricing table on this page and sort by what you actually consume: log ingest, hosts, spans, seats, and storage are not comparable on the same unit. Then run each calculator with your team’s real volume, not a generic placeholder.
