I created a free financial research hub with 100+ data pages covering every US state — from average mortgage payments to nurse salaries to credit card debt. All data tables are sortable, mobile-friendly, and free to reference. Here's how and why.
The Problem I Wanted to Solve
Ever tried to find "average rent by state" or "teacher salary by state" and ended up on 5 different sites, each with different numbers, paywalls, or outdated data?
I wanted one place where anyone — journalists, bloggers, students, financial planners — could find clean, sortable financial data for all 50 states. For free. No sign-up. No paywall.
What I Built
FreeFinCalc.net now has 100+ original data pages organized into 8 categories:
State Rankings (50 pages)
Every page has a sortable 50-state table with unique calculated metrics:
- Average Mortgage Payment by State
- FIRE Number by State
- How Far $100K Goes by State
- Best States for Remote Workers
- Rent vs Mortgage by State
- ...and 45 more at freefincalc.net/data
Salary by Profession (15 pages)
Average salary across all 50 states with cost-of-living adjusted rankings:
- Teacher Salary by State
- Nurse Salary by State
- Software Engineer Salary by State
- All 15 professions: freefincalc.net/salary-data

The Tech Stack

- 1,660+ total pages generated from ~15 data source files
Each data page includes:

- Visual bars and letter grades
- Key stats (best, worst, average, median)
- FAQ schema for rich results
- Related calculator links
Why I'm Sharing This
Because I want people to use and cite this data. If you're writing about housing affordability, link to the mortgage payment page. Writing about teacher pay? Link to the salary data. It's all free, and it helps us both.
Every page is designed to be the single best reference for its topic. No fluff, no paywalls, no sign-up walls. Just clean data tables you can reference in your articles.
Also: Word Counter Tool
I also built WordCounterTool.net — a free word counter with 350+ pages including:
- Word Count of Popular Books (Harry Potter, LOTR, Bible)
- Social Media Character Limits 2026
- Most Spoken Languages in the World
- Essay Word Count Guide
Both sites are 100% free, no sign-up, no paywall. Built as a solo developer project.
If you find the data useful, a link back is appreciated but not required.
