FAQ
How does the crypto dollar cost averaging calculator work?
Recurring buys smooth entry price in a volatile asset. The key number is your average cost, which tells you exactly where the position turns green. The underlying maths is: Average price = Total invested ÷ Total units accumulated.
What do I need to enter?
6 values: amount per buy, frequency, months of buying, average asset price over the period, current price, and fee per buy. Each field starts with a sensible default, so you can change one number at a time and watch the result move.
What does the position value today result mean?
It is returned as a money amount in US dollars and updates live as you edit the inputs, so you can compare two or three versions of a scenario in a few seconds.
Is this calculator free, and do I need an account?
Yes, it's free, and no account is required. Nothing you type is stored on our servers — the maths runs entirely in your browser.
How accurate is the result?
It applies the standard formula exactly, so the arithmetic is precise. Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
Who is this tool for?
It's built for anyone comparing money scenarios before committing — budgeting a payment, sanity-checking a quote, or seeing what a change in rate or term actually costs.
Accuracy and limitations
- Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
- Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
- This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
