Frequently Asked Questions
How are the shares calculated?
Total invested (contribution × periods) ÷ average buy price. $250 for 24 periods at an average of $40 buys 150 shares, worth $6,750 at a $45 ending price.
What should the average buy price be?
Your average cost per share, which for fixed-dollar buys is the harmonic mean of the prices, not the simple average. It is lower than the simple average because you buy more shares when prices dip.
Is dollar-cost averaging better than investing a lump sum?
Historically a lump sum wins more often when markets rise, because the money is invested sooner. DCA reduces regret from bad timing and fits people investing from each paycheck.
