I used Ubigi on my last trip to the States and had the same feeling - very convenient and dead simple.

Remaining number of shares is 67 Each share is valued at 1,500 yen I sell all 67 shares 67 x 1,500 = 100,500 yen ↑ Is Capital Gains tax also applied to the sale of these 67 shares? Yes, your capital gains on that portion would be 67 * (1500 - 1000), just as your capital gains on the previous portio...

Just for the record, in this simplified example you'd need to sell 36 shares to get 50,344 yen into your bank account after tax.

What she said is true but is simplified to the point of causing you confusion about how this works. When you make an investment, you buy shares. When you cash out of your investment, you sell shares. So in the simplest case let's say you've purchased one share for 100,000. Later the value of one sha...

Ah, okay then your understanding does appear to be off a bit. Let's use your numbers for simplicity's sake. You've purchased 200 shares @500 yen a share (assuming no fees) so your average share cost is 500 yen. If today you sold 80 shares @750 yen then your capital gains would look like (750 - 500) ...

In your bullet points are you leaving out some purchases that caused your average share price to jump from 500 to 625? The calculation after that looks right. (750 - 625) x 80 = 10,000 yen in profit which is subject to capital gains taxation. And, what if I start selling my initial investment amount...

You have to think in terms of share value when determining capital gains taxation. You buy 100 shares at 100 yen each, your average share price is 100 yen. Then you buy 100 shares at 110 yen each, your average share price is now 105 yen. Then you sell 50 shares at 120 yen each. We can calculate the ...
