Attic insulation matters, but so does your basement. Air leaks in rim joists (where your foundation meets the floor framing) can waste as much energy as a poorly insulated attic.
Sealing and insulating rim joists with spray foam or rigid board stops cold air from sneaking in and cuts heat loss where most homeowners don't think to look. You'll feel the difference in comfort and see it on your heating bill.
