Why I built a collection of 5 free, zero-signup career finance tools for solo builders

Hey everyone,

Transitioning to freelance work, contracting, or solo building comes with a massive administrative tax. Suddenly, you have to verify market salaries, audit long legal contracts, calculate multi-variable hourly rates, map out an exit timeline, and figure out corporate tax structures (LLC vs Sole Prop).

To eliminate this operational friction, I built SalaryParity—a completely free dashboard packed with 5 focused financial and admin utilities.

Here is how the workspace is structured:

Salary Reality Check: Instantly validates corporate offers against baseline market metrics.

Contract Scanner: Analyzes agreement text to highlight liability risks and IP traps before you sign.

Freelance Rate Calculator: factors in taxes, tools, overhead, and unbillable hours to give you a true sustainable rate.

Last Day: A runway tracker to plan your exit strategy from full-time employment.

LLC vs. Sole Proprietor: Maps out the exact revenue inflection point where incorporating actually makes tax sense.

There are no email capture walls, no popups, and no sign-ups. You can play with all 5 tools instantly.

I'd love to know what calculation models or administrative pain points I should build into the dashboard next!
