Before you rely on the result

Use the calculator as a working aid.

Subtract direct job cost from revenue to find gross profit, then divide gross profit by revenue to find gross margin. The required-revenue view uses the entered break-even base and target margin.

Applicability: For after-the-fact job review or pricing scenarios where the direct-cost and break-even assumptions are documented.

Field example: At $10,000 revenue and $6,200 direct cost, gross profit is $3,800 and gross margin is 38%. If the entered break-even base is $8,000 and target margin is 15%, required revenue is about $9,411.76.

Common input problems

  • Using gross margin as a substitute for net profit.
  • Mixing direct job cost with annual fixed overhead without a consistent allocation method.
  • Forgetting to update the break-even input when company conditions change.
