Where the quote goes

info
$2.4k
quote
Your work83%
Scope buffer17%

Of every $100 the client pays, $83 pays for the work itself and $17 shields you from scope creep. If the client pushes the price down, the buffer slice is what thins first; the work slice is your floor.

How this calculator works

The quote is built up, never guessed:

  • Base labor = estimated hours × your hourly rate.
  • Scope buffer = base labor × buffer %. It funds revisions and surprises so they don't become free work.
  • Project expenses ride on top at face value.
  • If a platform takes a fee, the quote is grossed up: quote = (labor + buffer + expenses) ÷ (1 − fee %), so the cut comes from the client's side of the number.
  • The proposed range runs from the quote to quote + 10%, for negotiation room.
  • The floor (shown once you've set up the rate calculator) is the price below which the project loses you money even if every buffer hour gets worked.
