About $100.05.
Goggles vary in quality and in price but the two are not tightly correlated.
I like goggles with lots of room inside the glass - the type that claim you can wear eyeglasses inside them. The extra airspace, and particularly the extra ventilation, makes them less likely to fog up (but actually wearing glasses inside them tends to negate that advantage), and the larger coverage helps avoid frostbite in those gaps that your balaclava leaves around your eyes. For hiking, go with minimal tinting - you'll be wearing them in blizzard conditions when it's already fairly dark.
In other words, the sort of ski goggle you can find for about $15 online.
If you're above treeline often you may want to carry two of them, so if one fogs up you've got another one ready to wear.
