Grammarly Pro costs $12 per seat per month. This plan is designed for individuals and teams, offering features like full sentence rewrites and tone adjustments. Large organizations requiring dedicated support and custom encryption must contact sales for Enterprise pricing.
At team scale, the Pro plan costs $1,200 monthly for 100 users, or $14,400 annually. For a department of 250 users, the monthly commitment is $3,000. These costs are fixed per seat, making the path to a positive return on investment dependent on verified time savings.

Break-even hours = seat price ÷ loaded hourly cost. Each seat pays for itself once it saves that much verified time per month.
How do per-seat costs impact the budget?
The Pro plan scales linearly, meaning a marketing operation can accurately forecast spend based on headcount. For an annual commitment of 100 seats, the budget requirement is $14,400. The Enterprise tier is reserved for organizations that need proactive AI and security features like BYOK encryption, which are not included in the standard Pro seat.
What is the threshold for a positive return?
The financial justification for Grammarly depends on the loaded hourly cost of your staff. At a $50 hourly rate, a Pro seat breaks even after saving just 12 minutes of work per month. If the user's loaded cost is $100 per hour, the software pays for itself in only 6 minutes. This low threshold makes it one of the more accessible AI tools to justify from a cost-benefit perspective.
To determine if this spend truly pays back, you must measure time saved against your specific writing baseline. Rather than relying on soft claims, NetLift allows you to track whether your team is actually hitting the 0.1 to 0.2-hour monthly savings required to zero out the seat cost. This shifts the conversation from a discretionary expense to a verified efficiency gain.
