Team AI Plan Cost Calculator (seats, monthly vs annual billing, VAT in won)

How it works

Monthly cost (US$) = standard seats × standard price + premium seats × premium price, using the monthly or annual-billing prices. In won: × exchange rate × (1 + VAT). A business registered for VAT can usually reclaim the VAT as input tax. Default prices are the Claude Team plan (standard US$25/US$20, premium US$125/US$100 per seat per month, 2–150 seats) — change them for any other team plan.

FAQ

Do we need a premium seat for everyone?

Usually not — give premium seats to the few heavy users and standard seats to the rest, then compare the totals here.

Is there a cheaper route for occasional users?

For people who use AI only now and then, a shared API-based tool can cost less than a seat. Use the subscription vs API calculator to check.
