Programme length is a cost, not just a schedule
An extra year is an extra year of living expenses and of earnings not earned, which is usually larger than the tuition differences people compare.
Comparisons tend to focus on tuition because it is the published number. The larger variable for most people is time: an additional year means another year of housing, food and transport, and another year out of full-time earnings.
So the question worth asking each institution is what proportion of students finish in the advertised time, and what the common reasons are when they do not. Course availability, sequencing and placement requirements are frequent causes and are specific to each programme.
Aid has time limits attached. There are caps on how long certain federal aid can be received and requirements about academic progress, so a programme that runs long can run past the point where aid continues.
Accelerated options, credit by examination and summer terms can shorten things, and each has its own trade-off in intensity. These are worth asking about before enrolling rather than once behind.
