T212 Profit Calculator

About

Most investors know the feeling — you're looking at a stock, you think it might be a good buy, and then you spend the next few minutes doing rough maths in your head. How many shares would I get? What would I actually make? Is it worth it?

T212 Profit Calculator answers all of that in seconds, right where you're already working.

It's as simple as three steps
Open any stock on Trading 212. Click the extension. The price fills in automatically — just enter how much you want to invest and where you'd sell. That's it. Your profit, shares, and return are calculated instantly.

New Investment
Working out a potential trade? Enter your investment amount and sell target. The extension tells you exactly how many shares you'd get, your profit in your own currency (GBP, EUR, or USD), and your percentage return — no calculator needed.

My Position
Already holding a stock? Enter your shares and average buy price (both shown on T212) and a sell target. You'll see your total profit vs what you paid, how much you'd gain from the current price, your current position value, and your break-even price — all in one glance.
