Freelance Project Quote Calculator

Quoting a flat project price gets risky the moment scope starts creeping, so it pays to build in a cushion. Combine your estimated hours, hourly rate, extra costs and a risk margin to land on a quote you can send without second-guessing.

How to use Project Price Calculator

  1. Enter the estimated hours and your hourly rate.
  2. Add extra costs (tools, subcontractors).
  3. Add a buffer/margin for scope changes and risk.
  4. See the price to quote.

Examples

  • 40 hours at $60 plus $200 costs and a 15% buffer ≈ a $2,990 quote.
  • Adding a bigger buffer for an unclear brief.

Supported formats & limits

  • Base = hours × rate + extra costs; price = base × (1 + buffer%)

Limitations

  • Estimate hours generously — projects usually take longer than expected.
  • Fixed-price work needs a bigger buffer than hourly.

Frequently asked questions

Why add a buffer?

Projects almost always run over — a buffer protects your profit from scope creep and surprises.

Hourly or fixed price?

Fixed price rewards efficiency but carries more risk, so use a larger buffer and a clear scope.

Should I show the breakdown?

Often a single clear price plus a defined scope works better than an itemised hour count.
