GitHub Copilot provides a tiered credit-based system starting at $10 per month for the Pro plan, rising to $100 for the Max plan. Tabnine uses a seat-based annual subscription model, with the Code Assistant at $39 and the Agentic Platform at $59 per month.
For a developer with a $100/h loaded cost, Tabnine’s base plan pays for itself after just 24 minutes of saved time per month. GitHub Copilot's value is tied to its credit allotments, which scale from $15 to $200 in value depending on the chosen tier.

Break-even hours = seat price ÷ loaded hourly cost. Each seat pays for itself once it saves that much verified time per month.
How do credit allotments impact Copilot costs?
GitHub Copilot pricing is structured around AI Credits and Flex allotments. The $10 Pro plan includes $15 in credit value, while the $39 Pro+ plan provides $70 in value. The $100 Max plan offers $200 in total credit value. Procurement leaders should monitor whether teams actually exhaust these credits, as unused capacity can diminish the effective ROI of the higher tiers.
When does Tabnine’s annual model provide better value?
Tabnine’s $39 and $59 plans are billed annually and offer a distinct advantage for teams requiring data sovereignty. These plans include unlimited usage when integrated with your own LLM on-prem or via your own cloud endpoint. This makes the cost predictable for high-volume engineering departments that want to avoid the variable constraints of credit-based systems.
The financial risk in AI adoption is the 'seat waste'—often 20-30% of licenses remain inactive or underutilized. To calculate true net return, you must measure the actual hours saved per seat against the loaded hourly cost of your developers. NetLift helps finance teams move beyond seat counts by tracking these time-savings metrics, ensuring that a $39 or $100 monthly spend is actually offsetting enough manual labor to justify the renewal.
