The duration of online MBA programs can vary depending on the institution and the specific program. While some programs may be completed in 1-2 years, others may take longer.

However, there is no indication that the duration of online MBA programs will be increased by 3 years in 2025. Such a significant change would likely require regulatory approval and would have a major impact on the popularity and affordability of online MBA programs.

If you are considering an online MBA, it is best to research specific programs and institutions to determine their duration and requirements.
