Hey everyone -- I built UseCalcPro because I was tired of calculator sites that load slowly, bury results behind ads, or require you to create an account just to divide two numbers.

The site now has 225+ calculators across 10 categories. Some of the most popular ones:

- Mortgage Calculator -- with amortization schedule and PMI estimates
- BMI Calculator -- with WHO classification and health context
- Budget Calculator -- 50/30/20 rule with visual breakdown
- Concrete Calculator -- material estimates for slabs, footings, and columns
- Solar Panel Calculator -- ROI, payback period, and energy savings

Everything is free, works on mobile, and gives you results instantly. No signup required.

I focused on making each calculator actually useful rather than just a basic input/output box. Most include visual breakdowns, formulas explained in plain language, related calculators, and practical examples.

Would love to hear which calculators you'd find most useful, or if there's a category I'm missing. Thanks for checking it out!
