We open-sourced the display-price calculator (free, one HTML file)

Description and use

A client‑side HTML tool lets freelancers adjust bids to match the displayed price, eliminating a ~25% display wedge in freelance marketplace negotiations.

Problem

Freelance marketplace negotiations often inflate the displayed price by ~25% compared to the submitted bid, creating a display wedge that misleads clients.

Outcome

Freelancers can now submit bids that match the client’s displayed price, avoiding the 25% display wedge and improving pricing accuracy.

Workflow

• 1. Open the single HTML file in a browser.
• 2. Enter the desired displayed price into the input field.
• 3. Optionally adjust the multiplier (default ×1.25).
• 4. Read the calculated actual bid to submit to the marketplace.
• 5. For reverse calculation, enter the actual bid and obtain the displayed price.

Evidence

The ×1,25 default is a wedge we measured on one marketplace across multiple live negotiations.

The calculator says so inline, and the README tells you to run a test bid before trusting it on anything that matters.
