About Punch The Numbers

Free calculators for people who need real answers — not a sales pitch.

Every calculator on this site exists because I needed it myself and couldn't find one that was fast, free, and didn't try to sell me something after I got my answer.

Why This Exists

Try Googling "mortgage calculator" and count how many sites make you enter your email, show you 14 ads, or redirect you to a lender before giving you a number. It's exhausting.

Punch The Numbers is the opposite: open the page, pick a calculator, get your answer. No signup, no email capture, no wall of ads between you and the math. Just clean tools that do one thing well.

Who Built This

I'm a safety and operations professional with 26 years in the transportation and distribution industry. Some of these calculators — like the TRIR/DART rate calculator and fleet cost per mile — come directly from tools I've built for my own work. Others — like the mortgage and compound interest calculators — are tools I use in my personal life and got tired of finding bloated versions of online.

The 3D print cost calculator ties into another project of mine: I run a small 3D printing operation printing replacement parts in ASA filament, and needed a clean way to price jobs.

The Rules

Always free. No freemium tier, no "unlock advanced features" paywall.
No login required. Your data stays in your browser. We don't store your inputs.
No misleading results. The calculators use standard formulas. The guides explain the math so you can verify.
Real content, not filler. Every guide is written to actually help you understand what the numbers mean — not just to stuff keywords for SEO.
