Dollar-cost averaging calculator

Dollar-cost averaging means buying a fixed amount on a fixed schedule, whatever the price. Enter your purchases to see your average cost per coin, or plan a schedule to see what it costs in fees.

Your average cost

How to read the result

Your average cost per coin is everything you spent divided by the coins you received. It is usually lower than the plain average of the prices, because the same number of dollars buys more coins when the price is low.

That is all dollar-cost averaging does. It takes timing out of the decision. It does not protect you from losses: if the price keeps falling and does not recover, every purchase loses money.

What this calculator does not do

It does not predict prices or tell you what would have happened in the past.
It does not know your tax position. Every purchase has its own date and price for tax.
It does not tell you how much to invest. Lesson 20 covers that.

This page does not look up live prices and does not save or send what you type. It is arithmetic, not advice: prices can fall, and you can lose everything you put in.
