Kickoff BOM purchase estimate example

A build lead estimates drivetrain, control, hardware, and bumper-fabric purchases while applying owned inventory and a 10% contingency.

  • Total before contingency: $902.16
  • Contingency: $90.22
  • Total with contingency: $992.38
  • Required cost: $752.40
  • Owned inventory offset: $148.00
  • Units to buy: 17

Assumptions

  • Part legality, safety, inspection, vendor, and school purchasing requirements must be checked outside SciPacket.
  • Already-owned quantities reduce purchase quantities but do not confirm usable condition or rule compliance.
  • Tax and shipping are planning estimates, not vendor quotes.
  • Do not enter vendor account credentials, payment details, student data, or official rule text.

Calculation notes

  • Purchase quantity = quantity needed - quantity already owned. The result does not go below zero.
  • Line subtotal = purchase quantity times unit cost.
  • Line total = line subtotal + shipping + estimated tax.
  • Estimated tax = line subtotal times tax rate percent.
  • Contingency amount = total before contingency times contingency percent.
  • Total with contingency = total before contingency + contingency amount.
  • Required cost sums rows whose priority includes `required`.

Questions coaches ask

QuestionWhat does this BOM estimator do?

It estimates purchase quantities, owned-inventory offsets, shipping, tax, contingency, required cost, and category totals in your browser. You can print, export CSV, or download a backup file.

QuestionDoes this check whether a part is legal or safe?

No. Use official rules, inspection resources, safety guidance, mentor review, and vendor documentation outside SciPacket.

QuestionWhat data should stay out of this estimator?

Do not enter vendor account credentials, payment details, banking information, tax IDs, student private data, or copied official rule text.
