Built by a Trader, for Traders

The story behind CosmikWaffle — and why every other calculator was missing the point.

What CosmikWaffle Is

CosmikWaffle is a collection of 35+ free trading calculators that don't just give you a number — they tell you what that number means for your trade.

Every other calculator gives you output like: 166

CosmikWaffle gives you: "Buy 166 shares at $14.20. If your stop at $12.70 hits, you lose $249 — that's exactly 1% of your $25,000 account. Your target at $18.00 gives you a 2.5:1 reward-to-risk ratio."

That's the whole difference. Context. Plain English. What it actually means for you.

Why It Exists

I kept opening four different browser tabs every time I wanted to analyze a trade setup. One for position size. One for risk/reward. One to check what win rate I'd need. Another to project my account growth.

And every one of them gave me a number with no explanation. I knew the formula — I'd just get a number and have to interpret it myself every single time.

I wanted one place that did all of it and explained the results like a smart friend who actually trades, not a textbook.

So I built it.

Questions or Feedback?

If a calculator is wrong, broken, or missing something useful — I want to know. If there's a tool you wish existed, tell me.

The best tools on this site came from someone saying "I wish there was a calculator that did X."
