About pnlcalculator.com

Clear numbers, built with care.

Hi, I'm Halim Türkoğlu, the product designer behind pnlcalculator.com.

I've spent years designing dashboards and complex tools for SaaS products — the kind where a wrong number or a confusing screen can actually cost someone money.

That background is why I care more about a calculator being clear and honest than sounding impressive.

Every calculator on this site works the same way: you enter real numbers and see the math. Nothing is hidden behind a login or a paywall, and no live market data or price feeds are used.
