DCA (dollar-cost averaging) means buying the same amount on a schedule instead of trying to time the market. This calculator uses bitcoin's real daily closing price since August 2017 and converts it to your currency with each day's exchange rate (for Argentina you can pick the official or the blue rate). You get the total invested, bitcoin accumulated, today's value, your average cost, the worst moment along the way and a comparison with investing everything at once.
How it works
Pick amount, frequency and date
For example, $100 every month since January 2020. Change the currency and the exchange fee if you want.
Each buy uses that day's price
Every purchase uses bitcoin's real closing price on that day, converted to your currency with that day's exchange rate.

What makes it different
Real historical prices
Binance BTC/USDT daily close since 2017, not a made-up curve or a yearly average.
Your currency, your exchange rate
Euros, Mexican and Argentine pesos (official or blue), Colombian and Chilean pesos, Peruvian soles, reais and more, from official sources.
Lump sum comparison
See whether investing everything on day one would have beaten spreading it over time.
The worst moment
The deepest loss you would have had to sit through and when it happened, which most calculators hide.

What people use it for
Check whether DCA worked
Test with real dates how someone buying every month would have done, drawdowns included.
Weekly or monthly?
Compare frequencies with the same budget and see how much the average cost changes.
Think in your own currency
Where the local currency loses value, seeing the result in pesos or soles tells a different story than dollars.
Argentina: official or blue
See the difference between the official dollar and the blue rate many people actually buy at.

How it differs from other DCA calculators
Most DCA calculators only work in dollars and hide the bad part. This one:
- Calculates in your currency with each day's exchange rate, not by converting at the end.
- Lets you pick the official or blue dollar for Argentina.
- Shows the worst moment along the way, not just the final result.
- Compares with buying everything at once with the same money.
- Needs no account or email, and your amounts never leave your browser.
Frequently asked questions
How much would I have today if I had bought $100 of bitcoin every month since 2020?
Enter 100, choose monthly and the date 2020-01-01: the calculator uses the real closing price on every buy date and shows the total invested, the bitcoin accumulated and its value at the latest available price. The result changes every day with the price.
What is bitcoin DCA?
DCA (dollar-cost averaging) means buying a fixed amount on a schedule, for example every week or month, without trying to time the market. You buy more bitcoin when it is cheap and less when it is expensive, which smooths your average cost.
Is DCA better than investing a lump sum?
It depends on the dates. If the price rises most of the time, buying everything on day one usually wins; if there are big drops after you start, DCA usually loses less. The calculator shows both with the same money for your dates.
Where do the prices and exchange rates come from?
Bitcoin: Binance BTC/USDT daily close since August 2017. Exchange rates: the European Central Bank for euro, Mexican peso and real; BCRP for soles; Central Bank of Chile for Chilean pesos; Banco de la República for Colombian pesos; and argentinadatos.com for the official or blue Argentine dollar. The page shows the date of the latest data.
Can I calculate in Argentine pesos with the blue dollar?
Yes. Choose ARS and then blue or official. The blue rate is closer to what people buying crypto in Argentina actually paid; the official rate gives a lower bitcoin price in pesos.
Does it include exchange fees?
Yes, you can set a per-purchase fee in percent (0.5% by default). It does not include withdrawals, local exchange spreads or taxes.
Does this tell me how much I will make in the future?
No. It uses past prices and the past does not guarantee what comes next. It is an educational tool, not investment advice: bitcoin can drop a lot, as the worst moment in the result shows.
