Microsoft 365 Cost Calculator
Same seats, three ways to commit. Enter your plan mix and see the yearly cost on annual upfront, annual billed monthly and monthly terms, plus a split that keeps your flexible seats on monthly so you can drop them without paying for the full year.
How the three terms work
Annual, paid upfront
One-year commitment, billed once. The lowest price per seat. You can add seats any time; you cannot remove them until the renewal date.
Annual, billed monthly
The same one-year commitment, paid in twelve installments. Microsoft charges about 5% more than paying upfront. Seats still cannot be removed mid-term.
Monthly
A rolling one-month term, about 20% above the annual upfront price. Cancel or reduce seats at the end of any month. Worth it only for seats you expect to drop.
The seven-day rule
After you buy or renew, you have seven days (168 hours) to reduce or cancel seats for a prorated refund. After that, annual seats are locked until renewal. Count carefully before day seven.
