Blends margin, scope buffer, deposit strength, and hourly rate protection.

Review the assumptions behind the result.

  • Labour is valued at the entered internal hourly rate.
  • Scope and revision buffers are added before target margin.
  • Deposit is calculated from the recommended project price.

Turn the output into a practical next step.

  • Use the buffer to price uncertainty before the client sees the quote.
  • Separate pass-through costs from your labour economics.
  • Use the deposit amount to reduce cashflow risk before work begins.
