Important
A $20 flat commission per referral is a moderate one-time payout for a well-known consumer product, spread across two products for slightly more promotional flexibility. There's no recurring component since it's a flat fee, and direct enrollment is simple, but no cookie window or other mechanics are documented.
High - $0.20 per free signup + $20 per premium upgrade confirmed; 30% also mentioned for higher tiers
What you would be selling
A $20 flat, one-time payout per referred customer with direct enrollment and a 90-day attribution window across two products.
Grammarly is one brand with 2 products, bought by different people. What one converted customer is worth cannot be worked out for any of them: that needs a rate, a plan price and a commission window, and this program does not publish all three.

Attribution window, payout terms and approval time researched on August 26, 2026.
Comparison notes rewritten on August 26, 2026.
Program duration confirmed on September 27, 2026: Grammarly's affiliate terms set no fixed end date but allow the company to close an affiliate's account after twelve consecutive months of inactivity.
Whether an affiliate must be a paying Grammarly customer remains unconfirmed as of September 27, 2026; the affiliate terms page does not address this either way, so the field stays blank rather than assuming no such requirement exists.
The exact flat-dollar commission amounts (twenty dollars per premium upgrade, twenty cents per free signup) could not be independently confirmed against Grammarly's own affiliate terms page as of September 27, 2026, which describes commission categories but withholds specific rates, directing applicants to the affiliate portal instead. These figures are left unchanged because no first-hand Grammarly source contradicts them, but they rest on prior sourcing rather than a fresh primary citation.
Network, cookie window, and application flow reconfirmed on September 27, 2026 by reviewing grammarly.com/affiliates directly: affiliates apply and are tracked through Impact (app.impact.com) with a ninety-day cookie window.
Checked whether Grammarly discloses any incentive for the referred customer on September 27, 2026 by reading grammarly.com/affiliates and its affiliate terms page directly; neither page states what, if anything, the referred customer receives, so the field is left blank rather than assumed to be nothing. The terms page does note that affiliates may only use coupon or promotion codes issued through the affiliate portal, but this describes what affiliates may distribute, not a confirmed customer benefit, so it was not treated as first-hand confirmation of a specific offer.
Read, and not published
Grammarly’s own material was read on these and says nothing. That is the answer: a program that does not state a term is not bound by one.
