Stock Average Calculator

About This Tool

Look, I get it—tracking your stock buys over time isn’t glamorous. But if you’ve ever bought shares at different prices and wondered, “Wait, what’s my actual average cost per share?”—this thing’s for you. The Stock Average Calculator is basically a no-nonsense way to figure out your break-even point without doing mental math or opening Excel every time. It’s not rocket science. You punch in how many shares you bought and at what price each time, and it spits out your weighted average cost. That number? It’s gold when you’re deciding whether to hold, sell, or buy more. No fluff, no jargon—just the math you actually need.

Key Features

• Simple input fields for shares and price—no confusing menus or hidden settings.
• Handles multiple purchases automatically. Bought 10 shares at $50, then 20 at $45? Just add both.
• Shows total investment and average cost per share side by side.
• Works for any stock, ETF, or crypto (yes, even that random altcoin you impulsively grabbed).
• No login required. No tracking. It runs in your browser and forgets everything the second you close the tab.
• Mobile-friendly. Because let’s be real, you’re probably checking this on your phone during lunch.

FAQ

Q: Why do I even need this? Can’t I just average the prices myself?
A: You could—but that’s wrong. Averaging $50 and $45 gives you $47.50, but if you bought twice as many shares at $45, your real average is lower. This tool weights each purchase correctly. It’s the difference between guessing and knowing.

Q: Does it save my data or send it anywhere?
A: Nope. Nothing leaves your device. It’s all local. Close the page, and it’s like it never happened. Privacy isn’t a premium feature here—it’s the default.
