Yes, your calculations are correct.

However, did you realise that using 10% annually (no compounding) means:

51875 / 1.10^10 = $20,000 present value (instead of 19,083.75).

And the present value of the dividends: 600(1 - 1/1.10^10) / .10 = $3,686.74

So why go to the contortions of compounding interest when looking at an estimate

over a long period (10 years), when all sorts of fluctuations can occur.

Btw, "compounding continuously" sounds GREAT....

but compare it to "cpd. daily" using a million dollars over 1 year:

1,105,170.92 (continuous)

1,105,155.78 (daily)

A difference of $15.14 !!
