It's roughly between $20-$25 per person. I recommend getting a membership. For the cost of my family of 5, it was only $40 more ($165) than it would be to buy one single ticket per member. We ended up with a premier membership. There are different tiered memberships but the additional discounts on food, shows and parking make it well worth the investment. We've gone 3 times since December already
$25 adults / $20 children
Children $20 Seniors $21 Adults $25 MIT students. Free Members Free
Every time I have been there admittance has been free if all you want to do is look around, there are shows at the planetarium and other places around the museum that you do need to pay for but there are also other attractions and displays of interest that cost nothing.
In between 9 and 25
Adult (12+) $25 Senior (60+) $21 Child (3-11) $20 Member (all ages) FREE
Membership entry is discounted. I recommend getting a Go City Pass. It includes most of the attractions in the city and surrounding area.
i believe entry is free if you become a member. Mass teachers get a discount. Their website explains all.
