Most Stata licenses are perpetual, that is, they are not limited in time. When a new version of Stata is released in the future you can choose to continue to use your current license at no charge or to pay for upgrade. The price of upgrade is always considerably lower than new purchases.

If you prefer, you can also choose to buy maintenance at the same time as the license. Maintenance is an annual fee that includes future upgrades of the license.

For larger workplaces there is also the possibility to lease Stata. A Stata lease is an N simultaneous-user license that expires after one year. If a new release of Stata occurs during this year, the new release is automatically sent to the lease holder at no additional charge. For prices see headings A6 and B4 in the web shop.

The sizes of Stata/SE leases are 15, 25, 50, 100, 150, 200 or larger, and the sizes of Stata/MP leases are 10, 15, 25, 50, 100, 150, 200 or larger.

With maintenance or a lease license, software expenses are predictable and you will always be using the latest version of Stata.

Although we cannot promise to never raise prices, the prices to renew leases and maintenance vary mostly with the exchange rate between the US dollar and the Swedish Krona.
