Bare ventilation equipment budget calculator

Quantity times unit cost is summed across equipment items; installation and controls are separate costs.

Cequip=Nm×cm+Nv×cv+Ns×csC_{\text{equip}} = N_{m} \times c_{m} + N_{v} \times c_{v} + N_{s} \times c_{s}

Worked example

Given

  • NmN_{m} = 4 unit
  • cmc_{m} = 500 $/unit
  • NvN_{v} = 4 unit
  • cvc_{v} = 800 $/unit
  • NsN_{s} = 10 unit
  • csc_{s} = 1,000 $/unit
Cequip=4×500+4×800+10×1000=15,200C_{\text{equip}} = 4 \times 500 + 4 \times 800 + 10 \times 1000 = 15{,}200
