Project Quote Calculator
A single number is a fragile quote. This builds a defensible band, with contingency baked in, so a few surprise hours do not erase your profit.
Why fixed quotes lose money
Fixed-price work fails when scope drifts and the buffer is zero. Add contingency up front, define what is included, and price anything beyond it as a change order. A proper proposal and contract tool makes that the default, not an awkward exception.

Frequently asked questions
Should I show the client the full range?
Usually quote the recommended figure as your price. The low and high anchors are for your own confidence and for tiered proposals.
How big should the contingency buffer be?
For well-understood work, 15%. For fuzzy scope or a new client, 25% or more. Estimates almost always run long, and the buffer is what keeps the job profitable.
